Figure 1: Double roll crusher geometry 2.1.5 Thickness of the RollFigure 1 is the geometry of a double roll crusher with a spherical particle about to enter the crushing zone of a roll crusher and is about to be nipped [4], [5]. For rolls that have equal radii and length, tangents drawn at. Double Roll Crusher - McNally Sayaji

The crushing rolls for primary and secondary crushers are made up of a roll body in polygon design which is equipped with exchangeable crushing seg-ments. As a result of the specific geometry between roll body and crushing segment an optimum form-fit is achieved, thus being able to stand up to the high crushing forces.

Its two dust extraction ports allow for safe removal of dust created in crushing samples. Roller gaps are adjustable to 2.54mm and access to drive components

The Roller Screen Crusher includes: dust encapsulation, pre-screen, two crusher drums and after-screen. A pre-crusher might be necessary to put on top of the pre-screen if many lumps are present (e.g. frozen coal). The crusher drums have a releasing mechanism to enable wood pieces, stones and other impurities to be rejected.

Environmentally friendly HRC 8 and HRC 800 are designed to be environmentally friendly with minimized noise and dust emissions. Robust HRC™ high pressure grinding rolls (HPGR) HRCTM 8 and HRCTM 800 are based on a high-pressure grinding roll

Lancaster Model 48 x 32 Double Roll Crusher •Roll opening: 48" x 32" •Drive: 30 HP •Capacity: Up to 60 tons/hour •Each roll opening: 24" x 32" The Lancaster Model 24 x 32 Roll Crusher is made for long life with a minimum of maintenance. This crusher is designed to reduce, in a single pass, material previously requiring primary and

For example, a single-roll crusher, employ shear together with impact and compression. Shear crushing is normally used under following conditions. When material is somewhat friable and has relatively low silica content. For primary crushing with a reduction ratio of 6 to 1. When a relatively coarse product is desired, top size usually larger
