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.
Due to the low crushing ration, the thyssenkrupp Polysius Double-Roll-Crusher is producing a product size ditribution with less content of fines and therefore it is the most suitable machine for the lime-industrie.

The crusher was then retrofitted with hydraulic cylinders to increase the pressure between the rollers. This was the predecessor to the high-pressure grinding rolls (HPGR) crusher, which became popular in Europe for applications in the cement industry. The introduction of the HPGR in minerals processing sparked at the beginning …
Where HPGR technology has replaced traditional methods of crushing and grinding (i.e. SAG and/or ball mills), customers have seen energy savings of up to 40%, and substantially improved mineral liberation. The unique bearing arrangement of the Enduron® HPGR delivers market-leading bearing life and is designed to protect against premature failure, …
Four-high precision grinding mill; Likewise, the Roll Crusher or Granulator is a common size reduction unit, which can successfully process a variety of materials. Additionally, the differential speed of smooth or corrugated rolls permits the production of a narrow range of particle sizes with a minimum of objectionable oversize and under-size ...

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 …
In a triple-roll configuration, the primary stage of crushing occurs in the top stage of the crusher and features a single roll configuration that performs the initial crushing. A double-roll arrangement on the bottom stage of the machine accepts the sized material from the top stage and sizes it further.

Two main types are indicated. The first type where the rolls are rotated in opposite direction with one roll spring loaded. Here, the mineral particles are nipped and crushed as they pass between rolls. In the second type, known as high pressure grinding roll (HPGR), the mineral sizes are reduced by compressive and interparticle pressure. …
