The vertical shaft sand making system makes the crusher have multiple effects of "crushing, shaping, sand making and grading" to achieve the best crushing particle shape, and it is equipped with vibration screening, as well as off-line ash cleaning pulse dust removal method to concentrate dust removal and collection.

On the shaft there are a series of spools; one spool for each roller. A rubber O-ring runs from a spool on the powered shaft to each roller. When the shaft is powered the rubber O-ring acts as a chain between the spool and the rollers, making the roller rotate. The rotating of the rollers pushes the product along the conveyor.

HPGR (high pressure grinding rollers), roll/roller crushers, or mineral sizers use two large rollers or a roller and a flat surface. The rolls can be serrated, toothed, or smooth. Vertical impactors use the weight and friction of the feed (autonomous) or add hammer-like processors. Horizontal shaft impactors spin feed against various surfaces.

Main shaft To keep the main shaft in good lubricating situation, you need to guarantee enough geese between thrust plate.The grease added to the bearing box needs to occupy about 50% of its space and be replaced every 3-6 months. When changing the engine oil, please use clean gasoline or kerosene to clean the roller bearing raceways.
