The specific function of each parts as follows.Overview: Many people know that the Cone crusher need overload protection device, but the structure and function of overload protection device is known by its range of detail. Overload protection device is mainly composed of four heavy cone crusher machinery safety arm, safety shoe, leaf spring, leaf spring clips, locking bolt, compression spring bolt, adjust the gaskets and other parts.

After the break, broken section is shell-shaped, which is very sharp.Obsidian can be processed into arts and crafts. After obsidian heated to above 1000 ℃ temperature, due to the internal moisture content, it will become white granular material with porous. In the ancient stone age, it was used as a knife, arrows and other cutting equipment. In the modern time, obsidian is made to surgical blade for the scalpel. Besides obsidian possess the characteristic of glass.

Its design concept is based on the client's requirements, which clear faults of your crushing place, surroundings as well as the fundamental complex configurations.Marble mobile crusher plant created according to a novel series stone crushing equipment's style concept, which expands the concept field of coarse crushing and fine crushing. This series marble mobile crushers genuinely apply simpler, higher efficiency decrease cost machines for clientele.

The actual machine is also uneconomical because it cannot be reversed because of wear on the center side. As evidence, the coal layer thickness on the pulverized surface is as thin as 1 mm, and there is a strong tendency to discharge outside rather than accumulating on the pulverized surface. As a result, the coal supplied from the center of the table is crushed on the center side where the peripheral speed of the roller is fast.C) In the case of a convex roller of D / R ≧ 4. The Although the pulverization property is improved as compared with the B roller, the main pulverization is performed on the center side of the large diameter, the main pulverization area is narrower than B, and is close to the linear pulverization until wear occurs.3 with a tire-type grinding roller, it was found that this was the roller that gave the highest amount of coal external discharge and gave high production. The difference between the tire diameter smaller than that and the tire diameter larger than that with the main grinding part in the center is greatly different, resulting in a large difference in peripheral speed, and the coal is scraped up and transported in the discharge direction and crushed with high efficiency. This is presumably because, for high-efficiency pulverization, the coal caught in the pulverization chamber is discharged with an excellent scraping ability, so that the coal layer thickness becomes thin and slip is likely to occur. In addition, when there is a surplus in power demand, coal is supplied less than the rated operation, but it is said that vibration is likely to occur during low-load operation.

In poorly sorted sediments, the presence of detrital grains with great size differences within a single concentrate makes mounting and identification difficult [20]. For these reasons, we routinely consider a size window as large as possible, including as many as 5ϕ classes (15–500 μm; see [3] for a detailed discussion of this crucial issue).Sediment samples may contain a mixture of clay, silt, sand, and gravel and thus need to be sieved before heavy-mineral separation.
