  PRINCIPLES OF FUNCTION

Raw material fed manually or automatically through the Hopper enters into the grinding chamber. The impact of Hammers on the feed material against the Liner Plates and also the inter-collision of particles reduce the material into fine powder. The Blower sucks out the fine powder into the Delivery Cone for collection and the Whizzer fitted between the Grinding Chamber and Blower obstruct the coarser particle to go into the Cone, allows only finer particles to pass. Excess air and fine air blown particles from Delivery Cone travels through pipe line to the Cyclonic Dust Collector Cone where super fine particles are trapped by the filter cloth bags and air is vented out partially. Return air goes to the grinding chamber again through the pipe to complete the air circuit without emitting the dust to the surroundings.

Illustrations are to give a general idea of the machine. All dimensions & specifications are subject to change and alteration. The figures mentioned under production are for guidance only and may vary from case to case depending on many a factor like Hardness, Moisture Content, Feed Size, Operative Fineness, Typical characteristic of the Feed Material, etc. For specific case, our offer document shall be referred.

Production follows the rule “Coarser the Mesh Higher the Output, Finer the Mesh Lesser the Output” and “Softer the Material Higher the Output, Harder the Material Lesser the Output”.

Material can ground higher than 150 mesh to 250 mesh also but in that case the production will be lower.

 OPERATION & MAINTENANCE

	Rotation of the machine should always be as per the arrow mark shown.
	Use the Hammers of equal weights opposite each other to avoid any vibration.
	To increase the fineness of the product Whizzer of 2, 4 or 6 Arm to be fitted as per the requirement. Using Whizzer with more number of Arms will give more finer product.
	To regulate the fineness, the Whizzer to be adjusted, forward and backward.
	If fine mesh is required, push the Whizzer towards the Blower and if coarse mesh is required, vice-versa, i.e. “Whizzer nearer the Disc coarser the Mesh, Whizzer nearer the Blower finer the Mesh”.
	Every Nuts & Bolts, pins of the Hammers of the machine to be minutely checked before starting the machine.
	Pipe Lines and Cloth Tubes to be cleaned by light hammering.
	Grinding Chamber is lined with 12 pcs. Top Liners & 8 pcs. Side Liners and blower Chamber with 17 pcs Liners. It should be replaced if and when required.
	Whizzer section is protected with Single Piece Conetype Liner.
	Before starting every day, pour 100 ml. lubricating oil in both the Bearings.
	Cleaning of Grinding Chamber and Pipe Lines through the inspection windows to be done once is a week. Light greasing of Bearings to be done once in a month.
	18 number Cloth Tubes fitted in the Cyclonic Cone should be washed and dried once in a month.
