With an overload protection feature, our roller crushers activate a device to halt operation of the crusher and feeder when it becomes jammed with oversized material. A tough frame consisting of welded and cast steel parts bolted together supports efficient crushing of large volumes of material.
Roll Crushers. Similar to Sizers, Roll Crushers can be used for the primary crushing of soft to medium hard material that can be slightly abrasive, dry, or wet and sticky. They are typically used in heavy mining applications and have a typical ratio of reduction of 4:1. Primary Roll Crushers are available in several designs:
The calculator below estimates the amount of time required to pay back one or more debts. Additionally, it gives users the most cost-efficient payoff sequence, with the option of adding extra payments. This calculator utilizes the debt avalanche method, considered the most cost-efficient payoff strategy from a financial perspective.

What sets the Sizer apart is its large scrolling teeth. This unique feature allows the machine to grip large pieces of material and expose its natural weaknesses, chopping effortlessly. To put that into perspective, it provides a breaking efficiency of approximately 10 times better than many other crushers.

opening of 22" by 30", a 46 x 46 jaw crusher has a opening of 46" square. Generally primary jaw crushers have the square opening design, and secondary jaw crushers have rectangular opening design. Jaw crushers are used as primary crushers in a mine or ore processing plant or the first step in the process of reducing rock.
When larger feed sizes require up to a 6:1 ratio of reduction to achieve the final product, a Triple Roll Crusher should be chosen due to the inherent design, which allows the larger feed sizes to be readily grabbed in the large throat opening between the top (primary) roll and crushing plate.

Figure 5.1 Schematic diagram of a crusher showingg the open- and closed-side settings. 5.1 Jaw and Gyratory Crushers. Jaw and gyratory crushers are used mostly for primary crushing. They are characterized by wide gape and narrow discharge and are designed to handle large quantities of material. The capacity of the crusher is determined by its size.
In single-roll crushers, a piece of material is fed into the gap between a roll and a solid, stationary plate. During the operation a complex stress state is generated in the destructed material.
The mathematical relations describing the behavior of roll crushers have been examined in [12,13]. The most complete modeling study of a hammer crusher is presented in [14,15]. Regarding the result …
