Fuzzy TOPSIS method to primary crusher selection for Golegohar
Selection of the crusher required a great deal of design regarding to the mine planning. Selection of suitable primary crusher from all of available primary crushers is a multi-criterion decision making (MCDM) problem. The present work explores the use of technique for order performance by similarity to ideal solution (TOPSIS) with fuzzy set Roll crusher circuit design.

What is a double roll crusher MIXING AND CRUSHING
The double roll crusher is mainly composed of rollers, roller support bearings, pressing, adjusting devices and driving devices. Install a wedge or shim adjusting device between the two rollers, so install an adjusting bolt in front of the wedge to adjust the fineness of the device material. That is, when the adjusting bolt pulls the chock, theBroad Prospects of Crusher Design Process.
