Grinding principles and usage of sand plant equipment

Sand plant equipment is the type of fine grinder which is used a free impact of material particles with a wear plate. Any hard or friable materials can be ground with low value of metal waste. This type of sand plant equipment is combined with a classifier for fine tuning of a product size.

Grinding principle A schematic drawing of a sand plant equipment is shown at Fig.into the sand plant equipment accelerator .An sand plant equipment accelerator rotates with a high speed and particles increase their speed by a centrifugal force. After leaving channels of the sand plant equipment accelerator particles impact with a wear plate .in the sand plant equipment grinding chamber. A high speed impact leads to destruction of particles into pieces of different size. Big particles fall down to outlet and later they transport to hopper by an elevator. Other particles lift by air stream into a classifier where blades make rotating dust flow. Middle size particles shift to wall by centrifugal force in a big chamber of a classifier and fall down to cone and later they move into an accelerator Small particles move by air stream to outlet Fine tune of a product size is achieved by changing of blade angle.

Usage of sand plant equipment You cannot use VSI sand maker 'as is'. We need to organize feeding, an air stream and its cleaning from product. Therefor full complete grinding line consists of a feeder, an elevator, a sand plant equipment with an air classifier, a cyclone, a fan and a bag filter. If raw material is soggy we need to organize drying before grinding.gy consumption.
