Frequently Asked Questions

From equipment selection and process optimization to maintenance and troubleshooting, these frequently asked questions address many of the challenges encountered in wheel blast operations. If you don’t find the answer you’re looking for, the Empire Wheel Blast team is always available to help.

General Blasting Performance & Pattern Issues

  • Why doesn’t my wheel blaster clean like it used to?
    • Check if the impeller is gone or if the blades are worn.
    • Determine if the blast pattern needs adjusting or if your parts have changed.
    • Verify that the machine is not out of abrasive and that the blast wheel motor is not running backwards.
  • Why is one end wheel blast chamber liner wearing faster than the other?
    • Your blast pattern may be off, or you may be experiencing “abrasive trailing,” which occurs when abrasive leaves the tip of the blade and trails to the other side due to high-speed momentum.
  • How do I test and adjust the wheel blast pattern?
    • Test the pattern using a painted plate of steel, never cardboard, as wheel blasters are aggressive and will immediately clog the screens with cardboard debris.
    • To adjust the “Hot Spot” of the blast stream, use an adjustable wrench and a medium flat screwdriver to rotate the Control Cage clockwise or counter-clockwise.
    • Ensure the notch in the cage is facing approximately 180 degrees away from the blast pattern, typically starting at the 12 o’clock position.

Amperage & Blast Wheel Motor Issues

  • Why can’t I get my blast wheel amperage above idle?
    • Check if the abrasive valve is open and adjusted properly.
    • Verify that the air is turned on to activate the abrasive valve.
    • Ensure the solenoid/Mac valve is not leaking or stuck, and check that the blast wheel motor isn’t running backwards.
  • How do I correctly set the blast wheel motor amperage during startup?
    • Turn the blaster on and check the Full Load Amp (FLA) against the motor’s schematic.
    • If the amperage is higher than the FLA, shut the motor off immediately to prevent an overload condition.
    • If the FLA is lower than required, adjust the abrasive valve cylinder to increase the abrasive flow rate until you reach the correct FLA.
  • Why is my blast wheel motor vibrating excessively?
    • A rotating component—such as the impeller, blades, bare wheel, or hub—is likely out of balance, which becomes highly apparent at 3600 rpm
    • Check all items for wear, and if nothing is obvious, remove them one at a time to isolate the problem
    • Rotate the wheel by hand and wait for it to stop; if it rolls back the other way, it is out of balance
    • Alternatively, the motor bearing may have failed

Recovery System & Dust Collection Issues

  • Why does my wheel blasting recovery motor overload keep tripping?
    • Check if the elevator belt is loose or slipping.
    • Inspect for a clogged rotary screen or an abrasive gate restricting flow, both of which can backfill the elevator.
    • Verify that there are no loose wires, the overload isn’t malfunctioning, and the overload isn’t set below the normal operating amperage.
  • Why isn’t my dust collector performing like it used to?
    • Check if the air pressure is too low for the reverse pulse system to function, or if the filter cartridges or dust pipes are clogged.
    • Ensure the slide gate isn’t open and that ambient air isn’t entering the duct and reducing the air volume/CFM.
    • Confirm whether it is time to change the filter cartridges, which is recommended at 5” of static pressure.
  • When should dust collector filter cartridges be replaced?
    • Empire Wheel Blast recommends replacing filter cartridges when static pressure reaches approximately 5 inches.
  • I installed a dust collector and the reverse pulse system is not working. What should I check?
    • Ensure the 110-volt electricity is hooked up to the reverse pulse system, as the equipment might be too loud for you to notice if it is on
    • Verify that the pneumatic air is turned on to the system
    • Check if the bolts on the bladder cover are loose, which allows air to leak by the air pipe

Belt Tracking & General Equipment Setup

  • How should I adjust a tumble blast mill after installing a new belt?
    • Tension the belt to the factory paint line to create a ¼” bow in the middle near the front roller.
    • Run the mill conveyor belt for about 15 minutes to verify tracking.
    • If tracking is improper, tension the same side the belt is moving toward by about 3/8” periodically (waiting 3-5 minutes per adjustment) until the belt centers.
  • What are the critical pre-startup checks before adding media?
    • Ensure the equipment is anchored, shimmed, and placed on a level, flat concrete floor with proper weather protection, as steel media can oxidize overnight.
    • Verify the correct voltage has been connected (208/230/380/460/575) to prevent component failure, and that the air is clean, dry, and set to the factory PSI requirement (typically 90psi).
    • Check all visible set screws, bump the motors to check rotations, ensure doors open and close properly, and recommend earth-grounding the dust collector in dry areas.
    • Make sure the abrasive valve closes just before the blast wheel motor comes to a stop, which serves as the primary safety device on most standard equipment.
  • What is your installation and Smart Start Service?
    • During startup, we verify wheel rotation, abrasive flow, recovery and separation, dust collection, part handling, controls,  interlocks, and safety functions. We process parts, adjust operating parameters, and optimize the blast pattern. Training is also essential. Operators need to understand  loading, recipes, inspections, and normal machine behavior. Maintenance personnel must know the primary wear points, service intervals, adjustment  procedures, and early indicators of a problem. Our Smart Start Service brings those activities together in a structured startup and production-readiness process. We  work with the customer’s team at the machine, using actual parts and operating conditions whenever possible. We confirm that the equipment, process settings,  material handling, dust collection, safety systems, and employee training are working together as intended. The objective is not merely to demonstrate that the  machine turns on. Before our team leaves the facility, we want the customer prepared to load parts, select or manage the correct settings, recognize normal machine  performance, complete routine inspections, and begin production with confidence. That provides peace of mind that the handoff is complete and that the customer is not left alone to translate a successful factory test into a working production process.
  • How does Empire Wheel Blast Equipment support customers after startup?
    • We provide technical assistance, troubleshooting, OEM replacement parts, preventive-maintenance guidance, and local support through our distributor network. Wheel-blast equipment operates in an inherently abrasive environment. Wheel components, liners, elevator belts, buckets, seals, bearings, and recovery-system  components will eventually wear. The key is managing that wear before it affects production quality or creates an unexpected shutdown.

Product Related Information

  • What are some key features and benefits of Empire Wheel Blast’s automated systems?
    • Empire Wheel Blast’s automated wheel blast systems are designed for 24-hour production with the goal of minimizing labor costs by automating processes that are otherwise accomplished with batch type blasters. We emphasize repeatable results, increased efficiency, and improved safety. Key features include PLC programming for consistent performance, manganese steel blast cabinets with cast alloy liners, entrance and exit vestibules for abrasive containment, multiple blast wheels, and ease of maintenance. The systems are designed to integrate smoothly into existing production lines, often directly preceding or following paint lines. They also offer the capability to clean a wide range of sizes and shapes, from small parts to large fabrications.
  • What are the benefits of using a Dual Chamber Spinner Hanger system?
    • Dual Chamber Spinner Hanger systems are designed for batch blasting fragile or awkward parts that are mounted on hooks. The dual-chamber design allows for continuous operation because one chamber is loaded and unloaded while the other is processing within the blast stream. They provide 360° workpiece coverage via a rotating spindle in each chamber, and can be programmed for repeatable performance. These systems enhance productivity and safety, and provide consistency of results.
  • How does Empire Wheel Blast’s Pipe Blasting system work?
    • Empire Wheel Blast’s pipe blasting systems are fully automated and use a skew roll conveyor to rotate pipe 360 degrees as it passes through the blast chamber. The process removes rust and mill scale, creating a surface profile for coating adhesion. It employs sensors to control media flow and includes a media recovery system with a bucket elevator and auger. The system utilizes abrasive shot propelled by a blast wheel, and it can be customized for various pipe sizes, usually ranging from 1″ to 42″ in diameter, along with various liner options within the chamber for increased durability. Industry-leading HMI controls allow the user to adjust settings, providing different surface finishes.
  • What advantages does Empire Wheel Blast’s TB120XT Table Blast system offer as an alternative to a traditional blast room?
    • The TB120XT is a large table blast system that offers an automated alternative to manual blast rooms. It features a 120″ diameter turntable with a 10,000 lb capacity, dual doors for easy access, safety interlocks, and powerful blast wheels. Compared to a manual blast room, the TB120XT provides greater operator safety, higher energy efficiency (due to lower process air consumption), and improved consistency in finishing quality. It allows for easier, more efficient and consistent processing of large parts without an operator needing to be enclosed within the blast chamber.
  • What makes your full-scale wire-mesh belt testing capability different?
    • It allows customers to evaluate continuous throughput rather than testing only a few parts in a small batch machine. We can process larger quantities, longer or  irregular parts, and mixed-part loads under conditions that more closely resemble production. After testing, we provide a documented report that can include process  parameters, media information, observations, adjustments, photographs, video, and recommendations. We also return the processed parts so the customer can inspect, coat, assemble, measure, or test them internally. Depending on the application, the report may also include surface-profile measurements, cleanliness results, peening intensity and coverage, cycle times, or estimated production rates. If a manufacturer is considering replacing a manual process or bringing outsourced work  back in-house, testing gives it a documented starting point rather than forcing it to recreate the process through trial and error. If possible, we strongly recommend  that customers visit our facility and take part in the testing process. That is often the ideal scenario for collaboration and for determining the best solution moving forward.  The customer is not being asked to purchase equipment based solely on our assurance. We provide physical evidence.
  • What product innovations is Empire Wheel Blast making to its wheel blast technology?
    • Innovation does not always mean adding technology for its own sake. It means solving a customer problem in a better way. We focus on practical innovation: changes that improve safety, consistency, productivity, flexibility, maintenance, or total operating cost. The technology must create measurable value for the customer.

General Company Information

  • How do you select the right Wheel Blast System for the application?
    • It all starts with a conversation and a customer’s part, along with mutual collaboration. In the early stages it is more art than science. While we consider ourselves experts within the Wheel Blast System industry, there are many things we need to know in order to get started on the correct path. Are there any applicable specifications to follow, are there any current in-house procedures to be followed, and do they have their own validation process just to name a few. These basic questions are indicators to provide an initial direction. As the process evolves it turns in to more of the science component, providing technical solutions to the application. In some cases, it is completely new process and we are able to provide options through various trials.
  • What is Empire Wheel Blast’s process for engineering wheel blast equipment to meet customer requirements?
    • We assign a team to engineered projects. That team can include a Regional Application Manager, Project Manager, mechanical and controls engineers, manufacturing personnel, and the local surface-finishing distributor.  Customers are updated through defined project milestones and regular communication.  Customers review  drawings and CAD models so they can confirm the machine layout, loading method, access points, controls, interfaces, and other important details. As the machine  moves into manufacturing, our Project Managers communicate progress and manage open items. Before shipment, we conduct factory testing and, when applicable, a formal Factory Acceptance Test using customer parts
  • What is the “Empire Difference”?
    • The “Empire Difference” refers to Gibson’s commitment to providing a high level of service and support, with a dedicated team assigned to each project including a Regional Manager, Project Manager, Engineer and local surface finishing distributor. It also includes on-site meetings, two-way communication, local support for maintenance and parts, data-driven machine selection, dedication to machinery evolution, in-house engineering, on-site demonstration labs, in-house manufacturing, installation and start-up services and post-installation support. This comprehensive approach emphasizes partnership, aiming to exceed customer needs for equipment and support. We focus on quality process, customer service and unbiased processing recommendations.
  • What is the purpose of Empire Wheel Blast’s on-site Demonstration Lab?
    • Empire Wheel Blast’s on-site Demonstration Lab allows customers to test their parts on actual machines before purchase. This helps customers evaluate expected results, confirming the correct machine for their application. This testing process is documented with formal procedures and helps the customer make an informed purchasing decision and adjust parameters immediately. It provides a physical, tangible demonstration of how the machine will process the customer’s parts, moving beyond theoretical projections. Customers are invited to attend and collaborate during these trials.
  • What are the primary factors I should consider when purchasing wheel blast equipment?
    • Specifications and price are important, but neither one tells you whether the machine will reliably produce acceptable parts in the customer’s facility.  Our approach is to understand the customer’s business objective first. We want to know what the company is processing, what result it needs, how many parts it must produce, how the  parts move through the facility, and what problem it is trying to solve. Only then Advancing Wheel Blast Technology can we recommend the right processing method and equipment platform. The difference begins with accepting responsibility for the process, not simply supplying a machine.
  • How can Empire Wheel Blast help to reduce the risks involved in making capital-equipment purchases for wheel blast equipment?
    • One of our strongest advantages is the ability to test actual customer parts in our Wheel Blast Demonstration Lab. Instead of relying exclusively on calculations or past experience, we can evaluate the part under real operating conditions. Our laboratory includes tumble, table, spinner-hanger, overhead-hanger, and wire-mesh belt  equipment. We can test different media, exposure times, wheel arrangements, part orientations, and processing methods. That helps us determine whether the required finish is achievable and which equipment platform provides the best result. Every Request for Test is assigned a sample number and reviewed by our demonstration lab team and the Regional Application Manager. We clarify the customer’s objective before testing begins, whether that involves surface preparation,  cleaning, deburring, peening, coating adhesion, appearance, or production rate. That structure keeps the test tied to the decision the customer must make.
  • How does Empire Wheel Blast handle replacement parts and maintenance for their equipment?
    • We emphasize the importance of using genuine OEM replacement parts for optimal performance and longevity of their equipment. We offer a wide array of replacement parts that are domestically manufactured and meet OEM specifications for materials and engineering, including components like elevator belts, blades, liners and motors. We also offer parts for other manufacturers including Goff, Coyote, Pangborn, Wheelabrator, Viking, and Bronco. We provide expertise and technical support to assist customers in maintaining their machines, and emphasizes faster response times with most parts in stock for immediate delivery. We see maintenance as an opportunity to troubleshoot issues before they lead to shutdowns.
  • Why is Empire Wheel Blast equipment manufactured in the U.S.A.?
    • Domestic manufacturing and in-house capabilities improve control, responsiveness, and long-term support. We fabricate many machine components and build  electrical panels and controls internally. We also retain the drawings, bills of materials, programs, and equipment history needed to support the system after it enters production.
