Using the impact force calculator.This versatile impact force calculator is useful for estimating the impact forces involved in collisions of different kinds.For example, it can be used to calculate the impact force of a vehicle car, truck, train, plane, football, of birds hitting a plane or wind mill, as well as for falling bodies that crash into the ground.
Free-of-charge bulk conveyor calculation program for many years jansen heuning is providing a calculation program for belt conveyors, bucket elevators, screw conveyors and chain conveyors.The program is very easy to use, in the english language and has extended help files to explain how the calculations are done and based on what formulas or data.
Pin mill work by similar principle as hammer mills impacts and shearing but with typically faster tip speed rotor-stator configuration of intermeshing pins which impact the particles as solids are directed through the intermesh pins.The mill product leaves by centrifugal forces to the periphery and is then collected or further processed.
