Figure 6.4 is a typical set-up where ores crushed in primary and secondary crushers are further reduced in size by a rough roll crusher in an open circuit followed by finer size reduction in a closed circuit by a roll crusher. Such circuits are chosen as the feed size to standard roll crushers normally does not exceed 50 mm.
Capacity: 60-520 t/h. Maximum feed size: 50mm for soft material, 40mm for hard material. Output size: 2-20mm. Price range: $14,400/ Set (the lowest price) Advantages. Under the same conditions, its output can be about 10% higher than that of an HVI sand making machine. The fineness modulus is adjustable and controllable, and …

crushing equipment for a specific purpose is influenced by many factors some of which are downstream of the crushing plant. Mineral processing is a complex operation. The principal procedure is crushing, that is the size reduction in the size of the fragmented rocks so that it can be rendered to another stage for further processing.
Roll crushers are a compression-type reduction crusher with a long history of success in a broad range of applications. The crushing chamber is formed by massive drums which revolve towards one another. ...
In order to make use of the rocks or ores obtained through quarrying/explosion in the Mining and Construction sectors, the materials need to beto reduce them to a smaller size. We call this process SIZE REDUCTION . The goals of the size reduction are as follows: 1.) Obtaining the size or surface area required for the use of the ore or material 2.)

If a single-stage reduction is required, then depending on the feed-to-product-size ratio of reduction, either a Single or Double Roll Crusher can be selected. Regardless of the crusher type selected, Roll Crushers allow for the material to fracture along naturally occurring cleavage lines, which helps with minimizing fines generation.
– Serrated or toothed roll crusher Smooth roll crusher • Two heavy smooth faced roll rotating towards each other at same speed on parallel horizontal axes • Size of the material caught by the rolls depends upon the coefficient of friction between the material and the roll surface • Dp = 0.04R + g Dp – maximum size of particle . R ...
The crushing rolls, which may vary from a few centimetres up to about 1.2 m in diameter, are suitable for effecting a small size reduction ratio, 4:1 in a single operation, and it is, therefore, common to employ a number of pairs of rolls in series, one above the other. Roll shells with either smooth or ridged surfaces are held in place by keys ...
