DELUMPING WET CORE DISHWASHER DETERGENT
 

Background / Requirement

An automatic dishwasher detergent manufacturer wishes to improve the efficiency of his process. At present, the customer lacks a piece of equipment to reduce up to 4 inch (100 mm), case hardened, wet core agglomerates. Therefore, they must allow their material from the mixer to partially dry in the floor bin before any attempt is made at size reduction. The breakdown habit of the partially dry material is such that fines are generated by the multi-stage reduction operation.

If they could reduce their agglomerates from the mixer in the wet core stage, they would:
   a) reduce fines level
   b) increase dryer efficiency
   c) eliminate partial drying in the floor bin
   d) eliminate finger crusher and oscillating grinder

Comil Performance

The Comil was introduced to size reduce the wet core agglomerates received from the mixer consequently supplying the dryer with the proper size particles.
a) The percentage of fines recycled to the mixer was reduced.
b) Some re-agglomeration occurred during the drying process however, the bond between these particles was weak and could be easily fractured by reintroduction to the Comil.

Summary

The Comil, by size reducing the wet core agglomerates directly from the mixer, greatly increased the efficiency of this process. The Comil was able to eliminate the finger crusher, save space and time by eliminating the bin drying, increase drying efficiency and produce a superior product. This is an excellent trouble-free Comil application.
