Silo / Hopper Design Calculation methods Why it is important. Powder has a given ability to slide and fall when it is stored in a hopper. A key variable that will have an impact on the flow of product outside of a bin is its cohesive strength. In a bin, the powder is submitted to pressure, due to the fact that there is a height of powder in the bin, the powder on top pushing on the powder ...
Get PriceBelt life varies greatly depending on not only how the belt is installed, but on how the belt is tensioned at installation. Belt tensioning also affects bearing life. When a belt is loose it will slip, causing excess heat. This leads to hot bearings and lowered bearing life.
