The crusher gives limestone a high finished product

May 22, 2019 by xiaoxuanxuan  

The Zenith Crusher allows the limestone to be finished. However, the reserves of limestone are in a hurry, and it is only enough for 25 years. Although the prime minister has a large resource title, with the exploitation and waste of resources, many resources have begun to appear in reserve. Limestone is a big example. According to the data, the reserves of medium limestone are only enough for 25 years, while the reserves of coal are enough to mine. As early as 2005, the proven reserves of limestone were 75 billion tons, of which only 39 billion tons were economically exploited (North City Planning and Design Institute, 2007). In 2007, the total production of cement was 1.36 billion tons, and the consumption of limestone was about 1.65 billion tons. The calculation was as long as the consumption was 23.6 years. In order to avoid waste and reuse of resources, it is necessary to consider when crushing and crushing the Construction waste crusher. . Even so, the proven limestone mine is only 45 years and a half. According to industry insiders, limestone is the second largest non-metallic mining product after coal. The reserves are far less than coal. The damage to the surface and landforms is far beyond the coal mining and cannot be restored. In modern industry, limestone is the main raw material for the manufacture of cement, lime and calcium carbide. It is an indispensable flux limestone in the metallurgical industry. After fine grinding, limestone is widely used in the manufacture of paper, rubber, paint, paint, medicine, cosmetics, feed, sealing, bonding, polishing and other products. In combination with the above factors, it is a good choice to use a crusher to crush limestone, which will not waste materials, but also allow the rejected unqualified materials to be reused.

What are the unstable factors when the crusher is running?

May 8, 2019 by xiaoxuanxuan  

The stone crusher looks like a simple mechanical device, and it will encounter many problems in production. No matter the size or the problem, it is normal for the mechanical equipment. After all, the unfinished mechanical equipment is also produced by human beings. Simple, about the base break of the crusher, I think this is a big problem, customers should not underestimate all the problems that occur on the mechanical equipment. The following small series introduces the treatment method of the broken base of the crusher, and hope that the majority of customers pay attention to this problem. The vibration energy generated by the normal operation of the crusher is insufficient to cause the substrate to break. Mostly due to the unstable factors in the operation of the crusher: if the crushing chamber of the crusher is seriously blocked, the mechanical vibration will be generated, which will have a great influence on the substrate. After many similar vibrations, it is likely to A base fracture occurs. The crusher jaws are not original or have been modified, which will also cause the jaw crusher to be unevenly loaded during operation, twisting and oscillating, causing the jaw crusher base to break. The jaw crusher has undergone a base fracture, and has been subjected to simple welding or welding defects, so that the machine may cause the base to break during normal operation. The vibration energy generated by the normal operation of the crusher is insufficient to cause the substrate to break. Mostly due to the unstable factors in the operation of the crusher: if the crushing chamber of the crusher is seriously blocked, the mechanical vibration will be generated, which will have a great influence on the substrate. After many similar vibrations, it is likely to A base fracture occurs. The crusher jaws are not original or have been modified, which will also cause the jaw crusher to be unevenly loaded during operation, twisting and oscillating, causing the jaw crusher base to break. The jaw crusher has undergone a base fracture, and has been subjected to simple welding or welding defects, so that the machine may cause the base to break during normal operation. The solution to the fracture of the crusher machine products base: general simple maintenance is welding repair, but the effect of this repair is not ideal. In preparation for overhaul, the entire base of the jaw crusher can be welded with steel plates. The high-strength anchor bolts with larger diameters are embedded in the concrete foundation, so that even if the crusher blockage operation produces strong vibration, it will not adversely affect the base of the jaw crusher. If the jaw crusher is prone to abnormal vibration, consider adjusting the jaws. Due to the serious bearing wear, the jaw crusher base can be broken to replace the bearing. The jaw crusher can be replaced if it is too loose or too tight. Replace the more rugged base to prevent similar failures from happening again.
