Known for several features such as fast and efficient grinding, easy operation, flexibility etc., our Laboratory Attritors are widely acclaimed by clients. Laboratory Attritors are used for obtaining homogenous and fine dispersions under controlled conditions. These Laboratory Attritors have a compact design, and are used for agriculture flowables, chemicals, ceramics, metal oxides etc. SF Attritor is used for producing fine & homogenous dispersons quickly & repeatedly under controlled conditions. Used for the manufacture of ceramics , inks, paints, coatings, metal oxides, ferrites, chocolates, chemicals & pharmaceuticals. The Attritor is often referred to as a agitated ball mill. The material to be ground is charged into a vertical tank filled with grinding media. Both the material and grinding media are then agitated by a shaft with arms causing the media to exert shearing & impact forces on the material. This action produces an extremely fine material measured in microns. No pre mixing is required. All attritors are provided with cooling jackets. Recirculating facility is available as optional. Attrition Mills, Also Called Stirred Ball Mills, Are A Very Fast, Powerful And Efficient Method For All Operations Of Grinding, Blending And Milling, Either Wet Or Dry. The Advantage Of An Attrition Mill Is That It Ensures That All The Grinding Media Are In Action All The Time. This Results In Much Faster Action. For Example, Wet Milling A Casting Slip Can Be Completed In One Tenth Of The Milling Time Required In A Conventional Ball Mill. Advantages of Using a Batch Attritor

• Ten times faster than ball mills
• Simple to operate
• Energy efficient
• No premixing required
• Minimum maintenance required
• Rugged construction
• Compact design
• No special foundation necessary

Advantages of SF Lab AttritorFast And Efficient Grinding, Scale-Up Capability, Numerous Options, No Premixing, Flexibility, Easy Operation, Repeatability, Low Maintenance SF Customer Knows From Experience That The Attritor Is One Of The Most Versatile Pieces Of Equipment In There Lab.

Working The Attritor Is Often Referred To Generically As A Stirred Ball Mill. The Operation Of An Attritor Is Simple And Effective. The Material To Be Ground Is Placed In A Stationary Tank With The Grinding Media. Carbon Steel, Stainless Steel, Chrome Steel, Tungsten Carbide And Ceramic Balls Are Commonly Used Media. The Material And Media Are Then Agitated By A Shaft With Arms, Rotating At High Speed. This Causes The Media To Exert Both Shearing And Impact Forces On The Material. The Final Result Of This Remarkably Efficient Process Is An Extremely Fine Material, Measured In Microns Or Fractions Of Microns, Distributed On A Very Narrow Curve. The Laboratory Attritor Works Up To Ten Times Faster Than The Conventional Ball, Pebble Or Jar Mill. Its Compact, Vertical Profile Requires Minimal Space. No Premixing Is Necessary. Adding Ingredients (Or Taking Samples) Can Be Done At Any Time During The Grinding. ConstructionThe Vessel Is Made From Thick S.S.304.

We are offering Hammermill to the clients. Hammer Grinding Mill, offered by us, is suitable for grinding a variety of food products such as spices, sugar, cattle feed, coffee, herbs roots, woodchips, fish, sawdust, poultry feed etc. We are offering Hammer Mill in several sizes and specifications to meet the varying requirements of clients. PrincipleThe material is passed from the feed tray to the grinding chamber where it is crushed to fine particles by free swinging hammers rotating at high speeds. The pulverized powder passes through a screen and is collected pneumatically by a cyclone collector. The pulverized material is collected at the bottom of the dust collector in bags.
