Understanding the Different Types of Crushers | Agg-Net

Jaw crushers. A jaw crusher is a compression type of crusher. Feed material is reduced by squeezing it between a moving piece of steel and a stationary piece of steel, with the discharge size controlled by the gap setting, ie the space between those two pieces of steel. The tighter the setting, the smaller the output size and the lower the ...

What is an Attrition Mill and How Does it Work?

Attrition mills mechanically reduce solid particles through the intense acceleration of particles against one another in a curved or flat grooved surface called a stator. These mills use a high-speed rotor to create centrifugal forces that facilitate the necessary particle interactions. Rotors' designs can vary, where some include multiple ...

Attrition scrubbers

Attrition scrubbers are used to scour particulate surfaces, removing undesired materials and breaking down clays – cleaning and desliming the particles prior to other treatment processes. It is the friction between the particles, created by turbulence and supplied by the machine's impulsion, that provides the highly efficient cleaning action.

differences between attrition mills and hammer mills

Attrition mills are best suited for fibrous materials such as grains, fibers, and wood chips, while hammer mills excel at reducing non-friable materials like stone aggregates or metal ores. In terms of advantages, attrition mills offer precise control over particle size distribution due to their ability to adjust grind settings easily.

Attrition Crushers

Attrition is a term applied to the reduction of materials by scrubbing it between two hard surfaces. Reducing it in size and shape. Used with friable or not too abrasive materials. Hammermills operate with close clearances between the hammers and the screen bars, and they reduce by attrition combined with shear and impact reduction.

More About Crushers

Jaw crushers use a pair of opposing jaw plates set in a V, at the base of which is an opening for crushed material to fall through. Because of the spacing of the jaw plates, the large pieces are crushed at the top of the plate, and become progressively smaller as they fall downward. ...
