The BTM is a low-speed mill that primarily grinds coal by impact and attrition. The VRM is a medium- speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed

The wheel speed, in terms of peripheral speed, is commonly in the range of 5,500 to 6,500 fpm (about 30 to 35 m/sec). High-speed grinding, operating at about twice that speed, is used on specially built surface grinding machines only, which are designed generally for abrasive machining and require appropriately manufactured grinding wheels.

This grinder has some cool features, and comes with a freeze-pack jacket for the grinding tube. Grinding non-frozen meat can create lots of heat, and it can sometimes cause ground meat to cook in the grinder. Leave the jacket in the freezer overnight, then clamp it around the grind tube to help remove that heat.
Inerting System Design for Medium Speed Vertical Spindle Coal Pulverizers The PRB Coal Users' Group plans to develop a Design Guide for Mill Inerting as an aid to users when designing a mill inerting system. This is a first draft document by the The Group on the subject of mill inerting. Feedback is encouraged. TABLE OF CONTENTS Preface 2

provide optimum performance. Worn grinding elements cannot create the maximum pressures required to reach maximum grinding effectiveness. Lower HGI fuels of course, exacerbate the true capacity problem when the grinding elements are worn. Illustration of the "grinding zone" on a MPS mill Horsepower/Ton Consumption
Historically, operators performed right-angle grinding primarily on carbon steel using small grinding wheels with fused aluminum oxide grain to remove welds or bevel parts. Grinding wheels were used for medium to large welds because of the improved performance and life compared with the fiber discs available at that time.
