Abstract. Double roll crushers (DRC) have the highest throughputs among primary crushers. In the oil sands, the hourly capacity may exceed 14,000 t/h. They are preferably used to comminute medium-hard rock or sticky materials. An unusual tough particle or unbreakable object may effect substantial dynamic forces in a DRC.

In previous studies, a model for double-roll crushers was demonstrated for a laboratory scale crusher having rolls of 200 mm diameter. The present study investigates the applicability of the model for an industrial scale crusher having rolls of 0.76 m diameter. Results of the study show that the model is valid for the large scale crusher …

Figure 1: Double roll crusher geometry 2.1.5 Thickness of the RollFigure 1 is the geometry of a double roll crusher with a spherical particle about to enter the crushing zone of a roll crusher and is about to be nipped [4], [5]. For rolls that have equal radii and length, tangents drawn at the point of contact of the particle

Marcy® Double Roll Crushers. Double Roll Crushers are useful for intermediate size reduction of hard to medium hard materials, such as rock or ore, after processing with a jaw crusher, for final reduction with a pulverizer. They also bridge the gap between laboratory and continuous production or pilot plant crushing capacities.

Crusher housing 2. Fly wheel 3. Base frame 4. Fixed roll 5. Floating roll 6. Hydraulic gap setting system Working principle Material is fed by a continuous feed arrangement into the middle of the machine between both rolls (a). The rolls operate at 5 m/s or even higher, and shear and compression forces crush the material between the roll in the ...

The core of the test plant is a double roll crusher DRC 450x450 toothed rolls. Fig. 3 shows a 3D view of the crusher without the drive units and inlet hopper. The roll crusher has two cylindrical rolls, which are designed as fixed (2) and retractable (4). The retractable roll is pretensioned with two hydraulic cylinders (3), which press it ...

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.

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 ...
