They can be used in coal, salt, coke, glass, and trona operations, among others. Triple Roll Crushers combine a Single Roll Crusher with a Double Roll Crusher to form a crusher that is capable of achieving a 6:1 reduction ratio in the primary stage and a 4:1 reduction in the secondary stage while producing a cubicle product at high capacity.

2008.4.9 Usually the double-roll type of crusher is used as the size reduction unit in urea granulation circuits. This device is constituted by two pairs of rolls that rotate in opposite directions at different speeds. The rolls can be smooth, corrugated or toothed and the distance between them (gap) is a key variable parameter.

2009.2.16 Abstract. A model has been developed to describe the breakage behavior of particle breakage in a smooth double roll crusher. In addition to this, an empirical relationship has been obtained between Hardgrove Grindability Index (HGI) of material and breakage parameters. The model uses matrix method of breakage process analysis.

2018.9.12 Double roll crusher (also called twin roll crusher) is composed of two cylindrical rollers as the main working mechanism (Figure 1). When working, the two round rollers rotate in opposite directions, and the material (ore) is crushed by the friction between the rollers, which rolls the material into the crushing cavity formed by the two rollers.

2008.4.9 The double-roll crusher model, first proposed by Austin et al. [15] and lately refined by Austin et al. [16], is based on the following assumptions: a) breakage of each size particle occurs independently of the other sizes, b) provided the roll diameter is large enough compared with the feed size and gap, the product size distribution depends

Double-Roll-Crushers are used for the crushing or medium-hard rock as well as for sticky and soft materials, i.e. clay, marl, limestone and similar raw materials. Sticky and soft materials are reliably crushed in 2 or 3 stages down to the required product size. Due to the low crushing ration, the thyssenkrupp Double-Roll-Crusher is producing a ...

2017.4.1 As a result, the forces acting in a double roll crusher could be much higher, at least locally, as one would expect for normal single particle comminution. This should be true even if the DRC is, as usual, starvation fed with just about 15 per cent of the crushing gap filled with solids. 3. Crushing and bearing forces.
