Refresh your VSI operation In an industry where reducing the cost per ton of an operation is paramount, the new Orange Series Rotor delivers results for Vertical Shaft Impactor (VSI) operators by adding operational uptime, securing faster service turnaround times and a longer wear life of parts. The twin goals of availability and serviceability Availability and serviceability of the Barmac VSI are greatly improved with Orange Series Rotors offering both longer wear life and easier servicing. Parts have been designed to more easily interchange and replace components to maximize wear life...

Wear part lifetimes drastically increased Primary components in the Orange Series Rotor will, in most cases, result in longer service intervals caused by an increase in wear life. As a result, you will benefit from increased uptimes and lower costs per crushed ton, reducing your total cost. Wear life increase Tip 30 - 50% Cavity wear plate 20 - 30% Upper and lower wear plates 30 - 40% Multiple rapid change wear parts The main wear parts are quick and easy to change. The new and unique design of the retaining bar structure further enhances the ease in wear parts replacement....

Orange Series Rotor components Multiple wear part replacement If multiple wear parts need to be replaced, you may consider removing the rotor and replacing it with a new assembly to keep downtime and service costs to a minimum. The removed rotor can be cleaned, rebalanced and wear parts replaced while the new assembly is in operation. Dressing the rotor Wear parts for the rotor are supplied either in sets or as individual components. All sets are weight matched to ensure the rotor is not subjected to an imbalance because of the addition of wear parts. The bare rotor is supplied pre...

Top and bottom wear plates Long lasting top and bottom wear plates provide maximum protection for the rotor body. The rotor is no longer hard faced - no more costly weld repairs are required. Removal/installation Access: Through the roof and spider. It is not recommended to remove and install the top wear plate with the rotor still in the crusher due to the requirement of rebalancing the rotor after installation. Removal 1. Remove the rotor from the crusher. 2. Remove the six retaining bolts from the underside of the rotor weldment top plate. 3. Shock the top wear plate loose with a hammer...

SIMPLE TIP SELECTION GUIDE - ORANGE SERIES ROTORS Red Black Yellow Green Orange Our wear plate tips - made of high quality tungsten carbide - have optimized profiles for extended wear life. The retaining bar holds wear plate tips in place without the use of nuts and bolts, making them simple to change. All tips are accessible through the service door decreasing your service time by up to 80%. Removal/installation Access: Through service door. 1. Loosen all the tips and the retaining bar in a port. This is best achieved by shocking the tip hangers and the retaining bar with a...

Back-up tips For maximum protection against rotor body wear, our back-up tips are made of tungsten carbide. Back-up tips are secured in slots in the rotor top and bottom wear plates. Tips, retaining bar and upper and lower wear plates must be removed when replacing these parts. Service door access makes back-up tips easy to replace. Cavity wear plates With the retaining bar removed, the cavity wear plates are free to be replaced or repositioned as their wear condition requires. Thanks to a retaining bar fixing method that does not require nuts and bolts, replacement takes less than half the...

Rotor balancing Bearing Adpater sleeve (840/990 only) Balance shaft Bearing rest Side plate Joining plates First assemble the rotor balancing machine. Ensure the bearings are not damaged or dirty. Clean off any dirt or old oil, and if they sound or feel too worn, we recommend the bearings be changed. After they are clean, add a little oil. Use a spirit level to be sure the rotor balance machine is level. Make sure there is no loose material or wear parts in the rotor that could move as it is turned. Balance the rotor with top and bottom wear plates. Balance the rotor weldment. Stage 2 The...
