How Single Roll Crushers Work. A Single Roll Crusher is made up of a toothed roll assembly, which crushes the incoming feed material against a crushing plate. The Single Roll Crusher is designed to reduce larger feed sizes to the desired product size at a
The hopper areas on single roll crushers are of a large, unrestricted design spanning the full width of the crusher roll. This construction allows the machine to crush large feed lumps delivered into the hopper. The hopper is flanged at the top and equipped with drilled bolt holes for attachment of an auxiliary hopper or feed chute above the crusher. Renewable, abrasion- resistant steel wear liners are furnished on the interior hopper
Conventional single-roll crushers use a simpler toothed-roll design, and are commonly used to reduce coal to approximately 2–3 inch (5–8 cm) topsize. The capacity of the single-roll crushers is a function of the roll gap, the roll length, and the speed, and ranges from about 30 tons/h (27 metric tons/h) for a 24-inch-long (61 cm) roll crushing to ¾ inch (2 cm), up to approximately 1500 tons/h (1360 metric tons/h) for an 84-inch-long (213 cm) roll crushing
Single Roll Crusher is an ideal primary breaker for crushing ROM coal, soft to hard limestone, ores, etc. They can be built in large sizes to handle high capacities and run-of-mine large lumps. OPERATING PRINCIPLE The crushing rings on the rotor crush the material by piercing and pressing the material against the breaker plate. When un-crushable material upto certain size limit
Material is crushed between teeth and a breaker plate consisting of hard liners. Providing a crushing ratio of up to 6:1, Bevcon Single Roll Crushers reduce large size particles in the feed to a medium size, while producing a low percentage of fines. The Single Roll Crusher design is very effective in reducing lumpy material because of the interrupted opening between the roll teeth and the corresponding grooves in the crushing
The single roll design is much more effective in reducing slabby material in comparison to jaw or gyratory crushers. When properly maintained, the "interrupted opening" between roll teeth and corresponding grooves in the crushing plate liners (see photo below) assure that slabby material cannot slip through uncrushed. 3.
A single roll crusher has a roll assembly consisting of a roll shaft and a fabricated roll shell with integral fixed teeth. In the single roll crusher, three different methods of reduction occur: impact, shear and compression. Entering the crusher through the feed hopper,
Single Roll Crushers. Single Roll Crushers are typically used as primary crushers that provide a crushing ratio of up to 6:1. They crush materials such as ROM coal, mine refuse, shale, slate, gypsum, bauxite, salt, soft shale, etc., while producing minimal fines. Designed with intermeshing roll teeth and a curved crushing plate, they are extremely effective in reducing slabby feeds.

Lancaster Products Roll Crushers are designed for long life with a minimum of maintenance. These crushers reduce in a single pass- material previously requiring primary and secondary crushing. The crushing rolls turn toward each other, confining all crushing to the area where the teeth mesh. Both rolls are timed to rotate at the same speed to maintain a true and highly effective

01.01.2016· Single roll crushers are also available which rotate a single roll against a fixed breaker plate. Mineral or rock particles placed between the rolls are nipped and then crushed as they pass between the rolls. Rolls are held against each other by springs. Radical changes to the design of roll crushers were introduced by Schonert,, as a result of fundamental work on breakage mechanisms.

The commonly seen roller crusher falls into three types: single roll crusher, double roll crusher and four roll crusher. In the working process, material falls in between the two rollers, and will be crushed. Normally, the material will be discharged from the bottom. When encountering material with high hardness, the rollers will automatically concede by hydraulic cylinder or spring which will

Design and production of an indigenous roll crusher from locally available materials for low hardness rocks was carried out in this work. The throughput capacity of the machine was 1.43tonnes/hour. The theoretical efficiency of the double roll crusher when crushing limestone was 60% while that of kaolin was 80%. Keywords: Double roll, crushing, Particle size, design analysis, solid mineral. 1
