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.
Starting from the base working principle that compression is the forcing of two surfaces towards one another to crush the material caught between them.Impact crushing can be of two variations: gravity and dynamic. An example of gravity impact would be dropping a rock onto a steel plate (similar to what goes on into an Autogenous Mill).

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 ...
The load conditions in the roll crusher, however, are usually point to face or face to face load conditions, which cause a larger contact area and therefore a slightly higher breaking force to be considered by a conversion factor (Schmidt, 2011). The method shows good results, however, for single particle crushing and low comminution ratios.
CrushersAll Shumar Crushers have two machined rolls to which the crusher segments are bolted. Each Roll is generally fitted with six crusher segments; some large roll diameter primary crushers do have more segments per roll. Manganese Steel segments are used in all Primary and most secondary crushing applications. All segments are …

Roll crushers reduce the size of the feed by crushing it between the two rolls, as shown in Fig. 4.7. These consist of two heavy cylinders revolving towards each other. The feed is …
Single Roll Crushers. Single Roll Crushers are typically used as primary crushers that provide a crushing ratio of up to 6:1. They crush materials such as ROM coal, mine refuse, shale, slate, gypsum, bauxite, salt, soft shale, etc., while producing minimal fines.Designed with intermeshing roll teeth and a curved crushing plate, they are extremely effective in …
This 911MPETMR Roll Crusher will crush rock samples from as coarse as 19mm (3/4") to less than -20 mesh. Its patent pending feed hopper evenly distributes samples over the full surface of rolls to create uniform crushing and surface wear. Its two dust extraction ports allow for safe removal of dust created in crushing samples. Roller gaps are adjustable to …
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.
roll with constant stroke in the entire crusher cavity allows for higher reduction ratio and more effective use of crushing energy. Under load, the freely rotatable roll slowly turns backwards which distributes the loads over the entire roll circumference and ensures uniform wear and maximized lifetime of the roll liners.
