Sand smooth roll crusher system existing in 1800mmx750mm light roll crusher l units, this design uses one with a prepared plan, the original small 1800mmx750mm light roll crusher spare, l Taichung 1900mmx800mm additional light roll crusher. It features: dual-motor drive, hydraulic coupling overload and snake spring coupling buffer and other devices. With cast frame, compact, rack has good shock absorption, reducing the effect of vibration generated by the impact load on the plant. Sand crushing roller hydraulic protection system device, can withstand the powerful thrust, both held at the broken material roll gap constant, stable and reliable, uniform particle size, and can effectively protect the equipment, and slow down the roller reset impact. Crushing roller for easy loading and unloading roller adopts modular structure, roll skin surface using third-generation Sand resistant materials, used for some time after the middle of the roll leather wear to a certain extent, special cutting device available on the roll surface to be restored to ensure return powder particle size, while the extended roll life. First look at Sand equipment materials and production processes. Sand making equipment from the process, there are two general points made steel body and welded body. Sand for the same, simply cast steel body is a whole body formed integrally vsi Sand Sand, which is made by the model casting. Such devices have the advantage in terms of resistance to vibration crusher manufacturers, but also to ensure its durability, extended service life. Welded body itself is put together by a few pieces of material, and by manually selecting the material welded together. Whether more superb welding process, in terms of firmness, but definitely better than the steel body.
