VSI Crusher Drive Belt Tensioning Correct tensioning is the most important factor necessary for long, satisfactory drive belt operation. Too little tension will result in slippage, causing rapid belt and pulley wear, and poor efficiency. Too much tension results in excessive strain on belts, bearings (especially motor bearings), and shafts. Measure Select the second…

VSI Crusher Rotor Balancing It is important that the rotor is properly balanced in order to provide the maximum trouble-free life of the shaft line assembly in the crusher. Most brands of VSI crushers manufactured rotor balance machines are designed specifically, and only, for this job. To get the best results from the balance machine,…

VSI Crusher Rotor Installation The life of the shaft line assembly is greatly reduced when the VSI crusher rotor is running with excessive vibration for long periods. When this vibration is extreme, there is potential for catastrophic failure, i.e. shaft breakage. One factor which has a direct influence on the smooth running of the crusher…

VSI Crusher Rotor Build-up The build-up in the rotor is a deliberately retained pocket of material that forms a surface over which rock slides and generally forms the shape of a wave with the crest toward the centre of the rotor. Primary function The build-up in the rotor needs to protect the internal walls of…

What are VSI crusher trail plates? VSI (Vertical Shaft Impact) crusher trail plates are components used in the construction of VSI crushers, which are machines used to crush rocks and other materials into smaller, more uniform particles. The trail plates are a type of wear part that is designed to protect the metal surfaces of…
