A pair of rolls is to take a feed equivalent to spheres of 3 cm in diameter and crush them to spheres having 1 cm diameter. If the coefficient of friction is 0.29, what would be the diameter of rolls? Calculations: The following formula relates the coefficient of friction (μ), radius of rolls (r), radius of product (d), and radius of feed (R):

The top stage of a Triple Roll Crusher has a 6:1 ratio of reduction, whereas the bottom stage has a 4:1. ... It is ideal for handling larger feed sizes due to the design and larger feed opening. In a quad-roll configuration, both the top and bottom stages have a 4:1 reduction ratio. The primary crushing stage at the top of the machine and the ...

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.

The Single Roll Crusher is designed to reduce larger feed sizes to the desired product size at a 6:1 ratio of reduction while producing a considerably lower percentage of fines. When properly fed in the direction of the roll rotation, the crushing action is carried out along the full width of the curved crushing plate, which ensures maximum ...

Each of the five materials was crushed into a Blake type of jaw crusher and the product from the jaw crusher was sieved using 12.7 × 10 3 µm and 6.35 × 10 3 µm size screens. 500 g of retained material was fed to the roll crusher manually approximately in 20 s. The gap between the rolls was 6.35 × 10 − 3 m for all the experiments. B.S ...

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 ...

How Quad Roll Crushers Work. Quad Roll crushers are designed for larger feed sizes and high ratios of reduction at high capacities. The top stage of the Quad Roll crusher is essentially made up of a double roll crusher, which is designed with the appropriate diameter rolls and tooth configuration to readily grab the incoming feed material.

The maximum equivalent feed particle size d A,max can be derived from the following geometric relationship which is obtained from the triangle ABC in Fig. 1: (5) cos α 2 = R W + s 2 R W + d A 2 With the radius R W of the roll, the gap s between the rolls, the particle size d A, the trigonometric relation (6) and R W = D W / 2 with D W as the ...
