IMPORTANT TECHNICAL INFORMATION ON PIN MILLS
Premium Pin Mill Is A Specially Designed Pulverizer To Deal Efficiently And Economically With A Wide Range Of Materials To Grind Them To Predetermined Fineness From Coarse To Fine Powder Up To 150 Mesh (100 Micron) And Above. The Grinding Operation Is Effected Through Beating, Shearing, Crushing And Auto Collision Of Material. Feeding Is Manually For Small Mills And For Medium And Large Capacity Mills, Either Hopper With Horizontal Gate Valve With Rack & Pinion Is Provided Or Screw Feeder With Variable Speed Drive. This Will Give Uniform And Controlled Feed Into The Mill, Pin Mill, Pin Mill Pulverizer, Pin Mill Manufacturer In India.

THE INTERNAL DESIGN
MAIN BODY / STATOR
Main Body Of Premium Pin Mill Consists Circular Husing To Accommodate Rotor With Pins, Screen Drum And Main Shaft With Nut. Housing Has Broad Base For Mounting. Other Half Is In The Form Of Hinged Door With Opening In Center & Round In Shape And Have Stationary Casted Rings Mounted On Inside Of Door. The M.O.C Is Either M.S Or S.S In Casted Form. Large Pin Mills Are Fabricated From Thick Plates And Are Welded And Streesreleaved.
The Drum Is Designed To Facilitate Required Mesh Size Screen To Be Fitted Around The Rotor. The Screen In Semi Circular (Two Halves) Form Is Held In Place By Outer And Inner Rings. The Rest Slot Decides The Location And Helps In Fixing The Screen Drum And Prevents From The Circular Motion. Correct Overlap Of Screen Avoids Leakage. The Adjusting Screws In The Rings Fix The Screen Drum Properly.
This Consists Of Several Concentric Rings Of Beater (Pin) Plates Arranged Around The Shaft With Heavy Duty Ball Bearing Mounted In Heavy Duty Bearing Housing With Adequate Arrangement For Lubrication.
The Pins In The Rotor Are Generally In “L” Shape And Are Riveted On Plate. The Number Of Such Pins Depend Upon The Rotor Diameter”. The Shape Of Pin Can Be In Form Of Studs (Round Pins) Also. Even Stator Rings Can Be Provided With Round Pins For Better Grinding Efficiency. Special Type Of Pins And Its Geometry Shape And Location Will Improve Grinding Efficiency Further. There Pins Are Made Out Of Forged Steel Or Forges Stainless Steel.
These Baloons Are Made Out Of Thick Cloth Bag And Is Fitted At The Top Of Chamber / Collection Bin. It Allows To Escape Air From The System And Avoids Back Pressure.
