Ideal for milling even easily oxidizable coal samples with upto ~12% superficial moisture without external air drying.
No flying dust escapes the mill and thus all the fed material is contained within the mill and collected for analysis.
A highly innovative helical feeding system ensures regulated feeding in the grinding zone.
A safety hopper mesh to protect operators hand from entering the grinding zone during material feeding.
A Positive air flow system to transfer the ground material into collection bin eliminates manual cleaning of the grinding zone after each operation.
No need of additional dust extraction system
Pulverizes small quantity of Laboratory sample (upto 5 Kg/hour). Sample upto a maximum size of -5 mm can be pulverized to - 212 micron as per the defined particle size distribution in IS 436.
The coal sample to be ground is introduced into the pulverizing chamber through a hopper. The material travels through a helical screw and it is uniformly delivered into the grinding chamber.
The rapidly rotating hammer's centrifugal force disintegrates material by shearing action between the fixed toothed circular inserts and rotating hammer arms.
As particles get smaller than the size of underneath sieves, the material passes through the sieve mesh and gets collected in a stainless steel container.
No dust is dissipated in the process. Need for separate dust extraction is eliminated and no sample is lost.
Small space separating the toothed circular inserts and rotating hammer arm plates determine the product fineness.
