Stainless Steel Pulverizer

This is a one type of powder grinding machine, operated with high speed electric motor with v belt. Its mechanism of The pulverized material is carried out of the mill by the flow of air moving through it. The size of the pulverized particles released from the grinding section of the mill is determined by a classifier separator. If the coal is fine enough to be picked up by the air, it is carried through the classifier. 

Operation:

The basic principle is straight forward. A pulveriser mill is essentially a steel drum containing a vertical or horizontal rotating shaft or drum on which hammers are mounted. The hammers are free to swing on the ends of the cross, or fixed to the central rotor. The rotor is spun at a high speed inside the drum while material is fed into a feed hopper. The material is impacted by the hammer bars and is thereby shredded and expelled through screens in the drum of a selected size. The pulveriser can be used as a primary, secondary, or tertiary crusher. The screen less pulveriser uses air flow to separate small particles from larger ones. It is designed to be more reliable, and is also claimed to be much cheaper and more energy efficient than regular hammer mills. The design & structure of the pulveriser is always determined by the end use. 

Rotor: 

Assembly rotates inside machine on heavy duty horizontal shaft, supported on two dustsbtight bearing housing fitted with bearings. Hammers swings around pint between catch plates. 

An adjustable replaceable whizzer and fan assembly are provided at respective location. 

Cyclone: 

It is single cyclone of LEHO design. A manual flap damper valve is provided below it. A frame and leg structure is provided for support. Bagginig height is 750 mm below valve. 

Cyclone Bag: Big single Bag balloon made from filter cloth. 

Ducting: Fan to cyclone with 90o bend and pipe.
