Mode of operation. Crushing of the feed material by the two counter-rotating rolls, either between inwards rotating rolls (Center Sizer) or between the outwards rotating rolls and the lined housing walls (Side Sizer). Successive comminution of larger lumps. Typically the Center Sizers are employed for pre-crushing, Side Sizers for medium-crushing.
The height should be where the second case to be roll sized just has its rim showing, the rest of the casing is in the tube. Mount unit in an appropriate place. The ROLLSIZER weighs 4.5 kilograms (about 10 lbs) and its dimensions are as follows: 270mm (10.6″) × 250mm (9.8″) × 230mm (9″). TFB Review: The Rollsizer, Roll Sizing Your Brass.
The rule of thumb for the Double Roll Crusher's ratio of reduction is 4:1. The simplified design gives these units excellent reliability and requires very little maintenance. The crushers are designed with built-in tramp relief …
Generally, a Quad Roll Crusher is recommended for a medium size feed material, while the Triple Roll Crusher, with its single roll top stage, is effective for handling larger size feeds. These machines do the work normally assigned to two separate crushers. Typical feed sizes range from 18" – 72" with final product size of ½" – 3".

In contrast to a Double Roll Crusher, the basic concept of the Mineral Sizer is the use of two rolls with smaller diameter shafts, because of the operation at a lower rotational speed by a direct high torque drive system. This design produces three major principles which all interact when breaking materials using sizer technology.
Diameter The roll diameter has to be sized correctly to provide an adequate angle of nip, as shown in the photo on the right. This angle of nip ensures that the crusher has the ability to grab the feed material and pull it into the crushing zone without delay.
In the primary crusher, a conveyable product (<300 mm) can be produced from the raw materials with a maximum edge length of 2.0 m in one-step. In the following crushing stages, the required target grain size can be produced in the secondary or tertiary sizer.
