Crusher for Fertilizer Manufacturing Industry

The flow diagram of fertilizer manufacturing industry contains four major units:
1) absorption tower,
2) gypsum converter,
3) concentrator-crystallizer, and
4) solid handling system.



A specific size of ammonium sulfate is demanded by the fertilizer and chemical industries. If suficiently large crystals of ammonium sulfate cannot be produced, an alternative is to compact the smaller crystals. A process for compacting the smaller size product was developed and used to estimate the additional costs.

For the compaction process, the smaller size ammonium sulfate is delivered to a fresh feed hopper. The crystals are weighed and then delivered to the compactors, which are two rolls that are hydraulically operated so that the materials passing between the rolls are compressed into flakes. The flakes are broken to desired sizes by a specially designed coarse crusher. Materials from the crusher are screened to extract the desired particle size. Oversize materials from the screens are returned to the crusher, fines from the screens are recirculated to the compactor. The sized product is usually passed through a rotary drum to remove the rough edges from the product.
