Typically used as secondary or tertiary crushers, McLanahan Double Roll Crushers provide a 4:1 reduction ratio and can be used following other McLanahan equipment, such as Feeder-Breakers, Rotary Breakers, primary DDC-Sizers, or Single Roll Crushers, when further reduction of primary crushed material is required.

Equipment Selection: Selecting the appropriate type and size of double roll crusher is crucial for efficient material processing. "Little P.Eng." engineers conduct thorough assessments considering material characteristics, feed size, required output size, and capacity to determine the most suitable double roll crusher for the application.

The double-roll crusher model, first proposed by Austin et al. [15] and lately refined by Austin et al. [16], is based on the following assumptions: a) breakage of each size particle occurs independently of the other sizes, b) provided the roll diameter is large enough compared with the feed size and gap, the product size distribution depends ...

The design of the Double Roll Crusher allows for a finer adjustment and therefore a finer product size. Cost. With the design differences also comes cost differences. The Double Roll Crusher is the more cost-effective option of the two. The main differences that make up the majority of the cost differences is the drive …

The crusher segment design from thyssenkrupp Polysius now makes it easy to replace the crusher segments. The reconditioning of the worn crushing segments can then be carried out cost-effectively in the plant's own workshop. ... Double-Roll-Crusher. Double-Roll-Crushers are used for the crushing or medium-hard rock as well as for sticky and soft ...

Machine parameters (roll profile and diameter, roll surface/teeth design and materials, feed conditions, etc.)- ... The core of the test plant is a double roll crusher DRC 450x450 toothed rolls. Fig. 3 shows a 3D view of the crusher without the drive units and inlet hopper. The roll crusher has two cylindrical rolls, which are designed as fixed ...

The DRC series roller crusher is widely used in tertiary crushing with the material feeding size less than 30mm and the product size 1 - 10mm of artificial sand making (cobblestone and construction waste), mineral …

If the material is hard, shock loading may occur and therefore special consideration needs to be given to the crusher design and drive configuration. ... rule of thumb for single-stage crushers is that a Single Roll Crusher provides up to a 6:1 ratio of reduction and a Double Roll Crusher provides up to a 4:1 ratio of reduction.
