Micron

TECHNICAL DETAILS & WORKING SYSTEM
Micron Pulverisers are swing hammer type, High speed, multipurpose impact grinding mills. The fine grinding is accomplished by impact of hammers on the feed materials in between of liner plates.
Micron Pulverisers are among leading manufacturers of pulveriser. The rendered product is made with quality grade mild steel or special C.I.casted. This provides strength and longer working life to the product and is damage free. The main shaft runs in two double rows self aligned heavy duty, roller or ball bearings.
The strong suction blower sucks the pulverized product and the air stream inside the mill carries the result product. In between the fan and the grinding chamber (having beaters/hammers) is the whizzer classifier consisting of blades with tips tapered to conform the contour of whizzer classifier cone. Whizzer classifier rejects the coarse material back to the grinding chamber for regrinding. The whizzer knife fitted with clamp control fineness of product. The entire wearing consisting of grinding chamber whizzer classifier and blower are lined with replaceable lining plates. These products are well recognized as these are fully automatic with auto feeding system for regular and regulated feed.
The blower delivers the pulverized powder or metal in the cyclone separator. Cyclone separates the material from air which is recirculated in the grinding chamber and air circuit is closed and excess air coming in to the system from feeder with material and all fine particles bled of through dust collector.
Grinding chamber is provided with a pocket. For iron, nut bolts are trapped here.
SPARE PARTS
All genuine and standard spare parts are available.
