Roll Crusher Working Principle. Roll crushers, or crushing rolls, or double roller crushers, are still used in some mills, although they have been replaced in most installations by cone crushers. They still have a useful application in handling friable, sticky, frozen, and less abrasive feeds, such as limestone, coal, chalk, gypsum, phosphate
Table 5: Advantages and disadvantages of double roll crushers and low speed sizers Figure 7: Typical double roll crusher schematic Figure 8: Typical low speed sizer schematic Impact Crushers. These crushers are made up of one or two heavy rotors with components attached that spin inside a casing.
1. Application. Jaw crusher is commonly used in a broken, will be a lot of material is suitable for the secondary crushing in such as cone crusher, impact crusher machine, such as feeding equipment, if the feed is very big, must use the jaw broken as the first stage crushing, and impact crusher broken is generally not suitable for marble, granite, too hard materials, this will be a big loss
In 1806, the roll crusher that was driven by the steam engine appeared. It sent the materials into the particular area by the surface friction of the roller. Then the materials would fall apart under extrusion or splitting. Now the roll crusher is usually divided into single roll, double roll and multi-roll crusher according to the number of

Oleg D. Neikov, in Handbook of Non-Ferrous Metal Powders, 2009 Crushers. Crushers are widely used as a primary stage to produce the particulate product finer than about 50–100 mm in size. They are classified as jaw, gyratory and cone crushers based on compression, cutter mill based on shear and hammer crusher based on impact.
Roll Crusher. For a given reduction ratio, single-roll crushers are capable of reducing ROM material to a product with a top size in the range of 200–18 mm in a single pass, depending upon the top size of the feed coal. Double-roll crushers consist of two rolls that rotate in opposite directions.
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
Comminution of the most different typology of rock with high percentage of sand in the output. The new device added to our range of standard tertiary impact crushers to comminute aggregates in small granulometry (4 - 10mm) with a high percentage of material smaller than 4mm in the output. The material is fed into the crusher via a system using a dosing impeller rotating with a constant ratio
4. * Roll crushers are used for producing additional reductions in the sizes of stone after the output of a quarry has been subjected to one or more stages of prior crushing. Roll crushers have a theoretical MAXIMUM reduction ratio of 4:1. If a 2 inch particle is fed to the roll crusher the absolute smallest size is 1/2 inch.
1. Application. Jaw crusher is commonly used in a broken, will be a lot of material is suitable for the secondary crushing in such as cone crusher, impact crusher machine, such as feeding equipment, if the feed is very big, must use the jaw broken as the first stage crushing, and impact crusher broken is generally not suitable for marble, granite, too hard materials, this will be a big loss
Double Roll Crushers. Double roll crushers reduce primarily through compression, although some shear is obtained with toothed rolls. Rolls for these crushers come in combinations of smooth, corrugated, and toothed designs. Double Roll Crushers produce a finer product at lower reduction ratios and capacities.
Double Roll Crusher. The double roll crusher can be applied in industrial sectors, such as cement industry, chemical industry and building materials industry for medium and fine crushing of material with medium and high hardness like limestone, coke, coal, etc. Double roll crusher features a two roll structure with smooth surface. Teeth Roll

cone crushers vs jaw crushers
Coal plants will use roll crushers, either single roll or double roll, as primary crushers. Usually, these crushers will have teeth or raised forms on the face of the roll. Roll crushers used for minerals and metal ores have smooth faced rolls. This series of crusher is used for crushing of ores and rocks, the advantages are: reliable structure
Crushing cases of the two crushers Manufactured sand made by roll crusher in Indonesia. The video shows the double roller crusher is turning small-sized stones into manufactured sand. There is a certain gap between the two counter-rotating rollers. Changing the gap can control the product size, shapes, and fineness modulus.
mechanism used.Based on the mechanism used crushers are of three types namely Cone crusher,Jaw crusher and Impact crusher. Our objective is to design various components of an Impact crusher like drive mechanism, shaft, rotor ,hammers, casing ,feed and discharge mechanism which will be useful in minimizing weight, cost and maximizing the capacity.
Disadvantages: The equipment is complex and expensive, and the one-time investment is too large. Semi mobile crushing station. Semi mobile crushing station, also known as modular unit or sled unit, is to place the machine body on the appropriate working level in the open pit and move the crushing unit as a whole (or separately) with the advancement and extension of the working steps by crawler
Double Roll Crusher. Slow Speed Crusing machine used with limited ratios for crushing when lesser fines are desirable. Documentation Product Enquiry Where to buy? Soft to medium hard material crushing. Minimum Fine Generation.
Double Roll Crushers. Double roll crushers reduce primarily through compression, although some shear is obtained with toothed rolls. Rolls for these crushers come in combinations of smooth, corrugated, and toothed designs. Double Roll Crushers produce a finer product at lower reduction ratios and capacities.
Triple Roll Crushers. Triple Roll Crushers are ideal for producers who want to accomplish two stages of reduction in one pass.

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
Primary crushing with impact crushers. The primary impact crusher offers high capacity and is designed to accept large feed sizes. The primary impact crushers are used to process from 200 t/h up to 1900 t/h and feed sizes of up to 1830 mm (71") in the largest model. Primary impact crushers are generally used in nonabrasive applications and
Mining crushers, sizers, hammer mills and roller screens. Today’s large product portfolio, including impact crushers, sizers, double-roll crushers, hammer mills or roller screens, supported by apron or chain feeders, enables HAZEMAG to offer the best solution to their customers, whether it is a single crusher or a complete processing plant.
The gyratory crusher is taller than the jaw crusher, thus needs a high workshop design. Besides, gyratory crusher is heavy than jaw crusher, it’s not convenient to move. Capacity. Gyratory crusher can work continuously, has high productivity and crushing ratio ( up to 6-9.5), working performance is very stable, light vibration.
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 the point of contact of the particle
A required crushing process may consist of just one rotor crusher, a combination of two rotor crushers, a combination of one rotor and one roll crusher, or just one roll crusher. Rotor crushers can treat quite coarse material with maximum inlet size of some 300×300 mm. As the typical crushing ratio is 10 at a single stage, the material can be
Both impact crushers and cone crushers purchased from regular manufacturers can meet the environmental protection standards required by the country. Under this premise, there are still certain differences in the environmental performance of impact crushers and cone crushers in actual production. The impact crusher belongs to the percussion crusher.
Impact crusher. Impact crushers make use of impact rather than compression to crush material. The material is contained within a cage, with openings of the desired size at the bottom, end, or side to allow crushed material to escape. There are two types of impact crushers namely (i) horizontal shaft impact crusher, and (ii) vertical shaft
