Why is the stone with high silicon content not recommended to be broken by hammer crusher?
Quartz, the scientific name of silicon dioxide, its content in the material to be crushed, according to the company's years of accumulation and customer experience, is an important reason for the wear degree of stone crushing machinery vulnerable parts.
According to the working principle of the crusher to distinguish, divided into hitting, extrusion, counterattack and other types, in actual production, direct impact machine such as the hammer crusher speed is the fastest, the impact type such as the impact crusher second, extrusion machine such as jaw crusher and cone crusher speed is the slowest.
In the process of high-speed collision, quartz is prone to chemical changes, which corrodes the relevant machine parts in contact with it and speeds up its wear rate. Now Shandong Sanxiang Heavy Industry machinery production of hammer crusher above the matching high chromium alloy hammer head in the face of high silicon content of basalt, granite and pebbles and other stone, wear resistance is not very good, but relative to high manganese steel and forging material hammer head is relatively good.
In principle, the stone company with high silicon content does not recommend that customers use the hammer crusher produced by our company to break, because as mentioned earlier, the working principle of the hammer crusher is to use the high-speed rotation of the rotor to provide greater kinetic energy to the hammer head, and use the direct impact method to break the material, during which the working mode is hard and the contact area of the material is larger. Due to the unstable chemical properties of quartz and itself with corrosion, it is easy to damage the high chromium alloy hammer head, which greatly reduces the work efficiency of Shandong Sanxiang Heavy machinery hammer crusher, and increases the cost of parts to the later production, which directly affects the production efficiency.
The crushing of materials with high silicon content is easy to use the impact crusher, jaw crusher, cone crusher and other working principle models, and the wear degree is relatively much lighter. If you come to Shandong Sanxiang Heavy machinery to buy machinery, please be sure to take the stone sample to, with years of experience, with the eye can roughly judge what kind of model, if you are not assured, you can send the sample to a special testing institution, technical analysis of the chemical composition of the stone sample, to make a more professional judgment.
Hammer crusher is our company's fist products, with the advantages of small investment and large output, has been loved by customers, but if used improperly, the later maintenance cost will be a large expense, so we must carefully choose the type of machine suitable for their own materials to be broken, such as stone with high silicon content, we do not recommend using hammer crusher crushing. Instead, choose a model that works on other principles.
