Plant Machinery

Gravel mining machine is mainly used for large-scale mining, ore crushing process, process for gravel or broken stone, generally refers to the original ore after blasting mountains, processed into finished products to meet the needs of granularity. With the gravel mining machine development, and to some extent to improve the overall process of mining, stone processing machine in large-scale mining as a core facility. Gravel in accordance with the ore out of the feed material size and grain size, gravel machine for coarse ore broken, broken, and broken bits in the field. Stone Mill performance continued to improve to a greater extent to meet demand.

In the twentieth century, the eighties, Stone Mill using two jaw plates of material extrusion and bending effect on the hardness of the material for coarse crushed or broken in processing; If the work is only briefly when the moving jaw arc swing , the industry said that a simple swing jaw breakers; if the working arc when swinging up and down but also for sports, said the complexity of swing jaw breakers. Jaw breakers are widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry and many other sectors, broken jaw breakers MPa compressive strength of not more than 320 different types of materials. Because of the demands development, in order to avoid damage due to replace the broken parts to affect the production, but also can be used hydraulic equipment to achieve security and adjustment. Some jaw breakers hydraulic drive is also used directly to drive the moving jaw plate to complete the material crushing action. These two types of hydraulic transmission equipment jaw crusher, often collectively referred to as hydraulic jaw breakers.

To the early 70s, cycle breakers, using hammer inside the cone cavity in the housing cycle in the movement of materials generated extrusion, splitting and bending role in a variety of hardness of coarse broken ore or rock crushing machine large. Broken cone axis with the upper bearing bush in the central part of the beam, its bottom is placed on the eccentric sleeve hole. Sleeve rotation, broken cone machine centerline as eccentric cycle exercise of its crushing action is continuous, so its efficiency is higher than jaw breakers.

The crushing operation of the uniformity of particle size marker generally higher than those operational requirements of the high rough broken, therefore, in the crushing chamber shall be a parallel to the lower area, while the broken cone must speed up the cycle rate, so that the material in the parallel region squeezed by more than once. Cone Stone Mill nesting population of small, mixed to the compound material has resulted in a non-breaking incidents, and because of, the crushing operation to discharge the demanding size, you must promptly adjust after the liner wear nesting population, thus Cone Stone Mill of insurance and adjustment of devices more necessary than the primary crushing operations. Cone-type lithotriptor lithotriptor with the cycles of the same, but only applies to operations in the crushed or broken bits of broken machinery. The continuous development of cone crusher, there are spring cone crusher, Symons cone crusher, and single-cylinder hydraulic cone crusher, as well as multi-cylinder Hydraulic Cone Crusher Equipment such as gravel.

At the same time, hammer mill and impact crusher continued development, particularly in counter-breakers than in more broken, and can make better use of the entire rotor high-speed impact energy. However, as board hammer easy to wear, it is broken in hard materials, applications were restricted, it is often used to rough broken, crushed or broken bits of limestone, coal, calcium carbide, quartz, dolomite, sulfide ore, gypsum and chemical raw materials, etc. The following in hard-brittle materials.

Stone Mill widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry and many other sectors. There is currently used jaw crusher machine crusher, Impact Crusher, winnowing mill, hammer crusher, impact crusher, roller crusher, crushing machine used in composite building materials, brick, coal, , metallurgy, mining, electric power, light industry and other industrial sectors, for crushing coal, shale, coal cinder, carbon, lime, cement have guessed that in the bentonite and the hard-brittle materials with rough broken, the broken and broken bits.
