Hydraulic product size adjustment allows producers to adjust for changes in product size requirements or to compensate for roll wear. Frequently Asked Questions About Double Roll Crushers Ask An Expert
Crushers play an important role in the material handling process for underground mine operations. The main purpose of a crusher is the size reduction of the feed. This size reduction is achieved by applying a force to the material, creating cracks in the material which in the end will cause the material to break into smaller pieces.
Double Roll Crushers can be equipped with an automatic lubrication system. Product size adjustment can also be changed with little effort using a hydraulic cylinder and hand …
The double-roll crusher model. Most of the actual size reduction devices have been widely studied because of their applicability in the well-known mineral processing industry. Many of them, like the ball and hammer mills, are represented by mathematical models that accurately describe their performances [10], [11], [1], [12], [13], [14].
Next, the two-toothed roll crusher was optimized based on the framework proposed by the Whiten model. The reasonable rolls gap and teeth length should be 75 mm and 23 mm, respectively. Further, a physical model of a two-toothed roll crusher was established to obtain the optimized roll diameter; it was later found to be >660 mm.
Output size. As low as 1/16" (1.6mm), with a practical minimum roll spacing of 1/8" (3.2mm) Throughput. Up to 70 tons per hour with a 1/8" (3.2mm) gap, depending on feed material . Industry Applications. Intermediate smashing and flattening for clay working applications in brick, block and tile; Smashing coal fines, coke breeze or gypsum ...

After the detailed design of this roll crusher, a prototype of the machine was built and extensively field-tested in a six-month campaign at a hard rock quarry in Germany. The crusher model ERC 25-25 selected for this purpose has a crushing roll of 2500mm in diameter and width. The feed opening to the crushing chamber is 2500mm wide and …
They have a higher capacity than comparable single-roll crushers. For example, a two-roll crusher with 24-inch-long (61 cm) rolls crushing to ¾ inch (2 cm) has a capacity of 75 tons/h (68 metric tons/h), which is approximately 2.5 times the capacity of a single-roll crusher with the same roll width and topsize setting.
