Virtually nothing sticks to the CRODON wear surface. Its naturally low coefficient of friction keeps even the most stickiest of materials from building up and causing material flow problems. We have seen conditions where operators once had to clean previous surfaces multiple times a day now never cleaning the surfaces again. This improves productivity and labor efficiency.

Unlike other non-stick surfaces, CRODON wear plate also resists wear and impact and is tolerant to heat past 700º F. And because it is also extremely resistant to abrasion, you won't have extremely thick (and heavy) sheets of material just to obtain a reasonable life cycle.

Mass flow is the angle that allows material to move without binding to the chute or hopper surface. It improves material through-put, prevents segregation, rat-holing, and corrosion based wear from material that clings to the wall surface. Easier mass flow allows less steep hopper and chute angles for more efficient and flexible hopper design.

The data below show the minimum angles that non-converging chutes and non-converging cone shaped hopper funnels need to achieve mass flow. The hopper outlet diameter for this data is two feet. The calculations are based on bulk material made of eastern bituminous coal and western coal from the Powder River Basin. Angles are measured from the horizontal where 0° would be perfectly flat. UHMW and stainless steel data are from published materials of a major manufacturer.
