action and facilitates self-cleaning of the surface of the Roll Shells. Roll spacing is controlled by an external screw adjustment with stops each 0.010 (0.254 mm). A detent is provided at each point. ROLL CRUSHERS A Smooth Roll Crusher, with both Rollers properly main- tained to a smooth, true surface, and kept set closely at a
Mar 10, 2017 To make such a reduction with rolls having equal capacity would require a roll at least 8 ft. in diameter, weighing about 80,000 lb. (see Fig. 1). The cost of the crusher would be about $1,500, and that of the roll, apart from the extra expense for foundations and transportation, about $8,000
The crushing roll shells are manufactured from wear resistant manganese steel castings with either plain or serrated surfaces depending on the application. The primary drive is via Vee belts to the drive shaft with cast steel spur reduction gears contained in a fully enclosed oil bath. The secondary roll is positively driven by heavy duty tyres
Steele Smooth Roll Crusher —. Medium to fine grinding to produce discs, strips or sheets of material. The Steele Smooth Roll Crusher plays a key role in bulk raw material preparation, processing clays, coal fines, coke breeze and gypsum waste. Twin rollers reduce pebbles and plastic lumps to form thin, flat discs, strips or sheets of material
Triple Roll Crushers. Triple Roll Crushers are ideal for producers who want to accomplish two stages of reduction in one pass. They can be used in coal, salt, coke, glass, and trona operations, among others. Triple Roll Crushers combine a Single Roll Crusher with a Double Roll Crusher to form a crusher that is capable of achieving a 6:1 reduction ratio in the primary stage and a 4:1 reduction
Crushing rolls might, logically, include roll crushers of the sledging type, the name, by popular usage, is restricted to the double-roll machine (with either smooth or corrugated shells) which crushes entirely by pressure between the surfaces of the roll faces
Jul 20, 2021 Figure 1: Types of Roll Crushers. Single Roll Crushers. Single Roll Crushers are primary crushers that provide a crushing ratio of up to 6:1. They reduce materials such as ROM coal, mine refuse, shale, slate, gypsum, bauxite, salt, soft shale, etc., from large size particles to a medium size, while producing minimal fines
