Types of Rock Crusher Machines

Types of Rock Crusher Machines Types of Rock Crusher Machines What is a crusher machine? A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust. ... The earliest crushers were hand-held stones, where the weight of the stone provided a boost to muscle power, used against a stone anvil. Querns and mortars are types of these crushing devices. How does a jaw crusher work? A Jaw Crusher reduces large size rocks or ore by placing the rock into compression. A fixed jaw, mounted in a "V" alignment is the stationary breaking surface, while the movable jaw exerts force on the rock by forcing it against the stationary plate. What is a crusher plant? A Crushing plant is one-stop crushing installation, which can be used for rock crushing, garbage crushing, building materials crushing and other similar operations. Crushing plants may be either fixed or mobile. Rock Crushers fill the duty of rock size reduction and can be classified in various stages of duties: 1. Primary crushing is the first crushing stage, 2. secondary crushing is the second, 3. Tertiary crushing is the third, 4. Quaternary crushing is a rare forth stage of rock crushing, Coarse crushing includes crushing operations discharging at sizes 4- to 6-in. or Metallurgical Content coarser; intermediate crushing comprises operations taking feeds 6- or 8-in. maximum and making products down to -1/2" or 3/8". Fine crushing is reduction by crushing to 1/4" or finer; the distinctions are not sharp. Rock Crushing is a mechanical operation in which a sufficient force is applied to relatively brittle solid particles in such directions that failure of the bonding forces in the particles is brought about. When the problem of crushing is thus approached, it becomes clear that crushing machines must be designed to exert either pushes or pulls on individual particles, since there are no other kinds of mechanical forces, and that the solid particles must be so introduced into and maintained in the force zone that the forces available can be applied to them. The study of the mechanics of materials has resulted in a classification of mechanical forces and of the structural elements for resisting them which, applied in reverse, supplies a terminology and basis for classification of crushing machines along mechanical lines. Thus the common load-bearing members are beams, columns, and ties; stresses induced in these by loading are tensile, compressive, and shearing; and the applied loads are stationary, slow-moving, or impact. Most crushers load the solid particles they crush as beams or short columns, but explosive shattering, whether by dynamite or by steam, loads them largely as ties. The induced stresses are mostly those of compression and shear, but tensile stresses arise in beam loading as well as in explosive shattering. The rate of loading in the majority of crushing machines is gradual; impact crushers form an important class, however; stationary loading is unknown. rock crusher machines types of crushers secondary crusher primary crusher gyratory crushers tyouboxJR https://autovehiclex.blogspot.com/   / 1ridha     / ridha
