The process of urbanization in China is accelerating. Due to over-exploitation of natural sand and gravel, some areas are on the verge of exhaustion, and the market is generally in short supply, which has become an important factor restricting the development of the sand and gravel industry.
Gravel is the current sand and gravel material. The main production method, the stone crusher is a crushing machine with a particle size greater than three millimeters in the final discharge accounting for more than 50% of the total discharge volume. Crushing operations are often divided into coarse crushing, medium crushing and Fine crushing. In addition, because the uniformity of the discharge particle size of the medium and fine crushing operations is generally higher than that of the coarse crushing operations, the cone crusher impact crusher jaw crusher plays a great role in the entire sand and gravel production line, and it also gives us the crusher Manufacturers have brought more opportunities.
The crushing of medium and fine crushing operations is larger than that of coarse crushing operations, so the loose volume after crushing is greatly increased. In order to prevent the crushing cavity from being blocked, the total discharge section must be increased by increasing the diameter of the lower part of the crushing cone without increasing the discharge port to ensure the required discharge particle size. The discharge port of the cone crusher is small, and the non-crushed materials mixed into the feed are more likely to cause accidents, and because the medium and fine crushing operations have strict requirements on the discharge particle size, the discharge port must be adjusted in time after the liner is worn, so the insurance and safety of the cone crusher The adjustment device is more necessary than the coarse crushing operation.
Henan Gold Mine Mining Machinery has developed products through continuous improvement of core technology and optimization of component design, and its output is high. This type of crusher has supports at the upper and lower ends of the main shaft, which can withstand greater crushing force and greater stroke, plus a special crushing cavity shape compatible with the lamination principle, so that the machine has a higher crushing efficiency. The cavity shape and lamination crushing principle produce crushing effect between particles, so that the proportion of cubes in the finished product is significantly increased, needle-like stones are reduced, and the particle size is more uniform. The cone can be realized, and the hydraulic and lubrication system controlled by double insurance can ensure the overload protection of the machine and good bearing lubrication. Therefore, the contribution of the cone crusher to the sand processing industry cannot be underestimated.
