Attrition Mill

Attrition Mill Advantages / Features

• Ten times faster than ball mills and Easy grinding small batch with easy temp control.
• No premixing as Ingredients may be added at the beginning or any other time during the process.
• Fine homogeneous dispersions as average particle sizes of 1 micron or less.
• Low power consumption as all power is used for grinding and dispersion.
• Minimum floor space as a mill is extremely compact in size and requires no special foundations.
• Shorter grinding times – up to ten times faster than conventional equipment, such as ball or pebble mills.
• Corrections can be made without stopping the machine.
• No need grinding media separation and multi type grinding media can be process. 
• Manufacturing facility approved well-known consultants.
• Easy to install and works efficiently.
• Small occupation area low investment cost.
• Low operation cost and long service life.
• Good final product quality and easy to maintain.
• Environmentally friendly and high classifying capacity.
• Can be manufactured as per Client specifications.

Working/ Operating Principle of Attrition Mill

Attrition Mill machine works along the similar principle as the agitator mills in which the vertical special agitator with self-rotating hardened dot welded beaters is close-fitted with agitator shaft arranged in staggered positions one above the other and at a specific angle in relation to one another. In Attrition Mill, the agitator runs in a container which can be heated or cooled as required. 

Attrition milling’s batch type operation where ingredients to be ground are served in as a suspension or as single modules with built-in product discharge valve with screen allows the separation of product material and grinding media. Size and material of the grinding media depend on the product to be processed and the exchange of the grinding media is made possible by a tilt apparatus. Attrition Mill’s capacity is dependent on prerequisite particle size of the reduced material, with rougher products produced at higher rates. The replaceable Attrition milling plates are provided in numerous patterns to optimize size reduction for specific types of materials. Vertical orientation of the discs, together with a quick-release hinged stator disc housing, permits for thorough clean-out between product runs.

Applications of Attrition Mill

Raymer Engineering Corporation Attrition Mill is extensively used for reducing fibrous and friable materials within a comparatively narrow particle size range from coarse down to 100 mesh. Attrition Mill are widely used where materials that cannot be reduced by impact (hammer mills or pin mills) or by screen classification (screen classifying cutters) including: metal powders grains, spices, seeds, tobacco, roots, cellulose, fibers, minerals, and coatings, inks, and other relevant industries, for the reduction and dispersion of pigments in liquids. Attrition mills are mainly used for paints manufacturing, coatings manufacturing, inks manufacturing, dispersion of pigments in liquids manufacturing, processing enamels manufacturing, cement primers manufacturing, for emulsions manufacturing, etc.
