The double-roll crushers, in contrast, are equipped with two rotating cylinders that compress the material between them. The double-roll crushers can be further divided into the smooth-roll crushers that have the smooth cylinder surfaces and toothed-roll crushers that have toothed or corrugated surfaces to provide the better grip and crushing ...

Introduction. In the heavy industry sector, efficient and reliable crushing equipment is essential for processing materials effectively. Double Roll Crushers have emerged as a …
Double-roll crushers are able to crush more finely than single-roll crushers, because they are designed with teeth that mesh together rather than rotating past a smooth plate. ... 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.
Crush + Size Technology manufactures double roll crushers based on several technical innovations. In particular, the focus is on the research and development of crushing roller and crushing tool geometries in order to carry out comminution processes much more effectively and efficiently than with conventional or previously known roll crusher technology.
Similar to a Double Roll Crusher, the coefficient of friction between the roll surface and the material to be crushed, incorporated with a relation between the size of the feed and the size of the product fixes the diameter of the rolls and also determines whether a particle will be drawn into the rolls and gets crushed or not.
Double-Roll-Crusher. 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. Find out more. Roll Sizer The RollSizer are capable of crushing ...

In coarse comminution, double roll crushers (DRC) are used for the size reduction of blasted materials and in secondary comminution. In the primary crushing stage, DRC with toothed rolls are of particular importance. In contrast to smooth rolls, these offer improved nip conditions so that larger particles can be nipped, and crushed.
The rolls provide toothed patterns suited to the feed material. Single Roll Crushers generally handle larger feed sizes at higher reduction ratios in higher capacities. These machines are also great as lump breakers. Double Roll …

Binder+Co Double roll crusher. An optimum grain size of 10 to 50 mm is crucial for sensor-based sorting of cullet since a higher content of fines (0-10 mm) would have an unfavourable effect on sorting performance. In the form of the double …
Material that is to size can pass around or between the shafts. The breaker bar can perform an additional reduction, further reducing the material to size. Mineral Sizers can accept feed lumps up to 1200 mm (47") and reduce them down to 300 mm (12"). The product size can be adjusted by increasing or decreasing the space between the roll bodies.
The range of the smooth-face rolls, for example, is from about 400 ft/min for the small 12-in. rolls, to 2000-2200 feet/minute for the heavy-duty 72″ machine. The single-roll crusher has a tip speed of 400-450 ft/min while …
A typical application: fine crushing e.g. from 30 mm feed size to 5 mm product size, approx. 80% target particle size largely avoiding fine grain and dust; Crushing roll surface according to the material characteristics (smooth, machine cut grooves or built-up welded rips) Integration in semi-mobile plants possible

The Double Roll Crusher crushes a wide range of material types reaching compressive strengths of up to 150 MPa and higher. It is less sensitive to wet and sticky material than RollSizers and …
Mode of Operation. The material is crushed by shear- and tensile forces generated by high rotor torques at a low circumferential speed. Due to the arrangement of the crushing tools the fines in the feed can pass through the crushing rolls similar to a roller screen without being crushed.
However, Single Roll Crushers provide limited product sizing and are limited in throughput capacity. Double Roll Crushers feature two rotating roll shafts that crush material between the teeth and roll bodies. These types of Roll Crushers produce a cubical product with minimal fines generation, and can handle higher capacities.
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 reducing slabby feeds.
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.
