Solve the problem of easy breakage of the crusher crown

Solve the problem of easy breakage of the crusher crown, process operation of the gravel production line


The crusher is suitable for crushing operations of medium hardness materials such as coking coal, sinter, limestone, metal and non-metallic ore. Most suitable for small and medium-sized non-metallic ores. It is most suitable for medium and small crushing operations in small and medium-sized non-metallic mines and chemical industries. The minimum particle size can reach below 100 mesh. The crusher has a simple structure and convenient operation, and can achieve an ideal crushing granularity by adjusting the gap of the crushing roller, and the performance is stable. The crown of the crusher is prone to breakage, the reasons are as follows:
  1. The tooth crown is affected by the impact force when the large ore is blanked, and the back of the crown is fatigued and broken.
  2. Due to the high rate of large ore source, the crown is also vulnerable or broken.
  3. The extension and extension of the crown bolt will cause the crown to break.
  Solution: Add two steel plates on both sides of the bow crown of the crusher to make it a box crown, which can make the life of the crown more than 2 years.
The sand and gravel production line is a special production line equipment for the production of sand and stone for construction. It is 50% more energy efficient than traditional sand making machines. It can make rocks, sandstone, river pebble and other materials into various particle sizes that meet the requirements of construction sand. The sand made from sand and gravel production line has uniform grain size and high compressive strength, far more than natural sand and ordinary hammer sanding. The sand produced by the machine is more in line with the building requirements and can improve the building quality. Sand and gravel production lines, sand and stone equipment, in addition to the start-up and daily maintenance of the equipment, almost no manual operation. The production efficiency is high, the running cost is low, the output is large, the income is high, the finished stone has uniform particle size and good granular shape.
In the design of the gravel production line and sandstone equipment, due to the reasonable matching of the crushing equipment at all levels and the rigorous spatial cross layout, it has a small footprint, high investment economic benefit, good quality of crushed stone, and stone powder production. The low output rate is characterized by an advanced electronic control operating system, which ensures smooth discharge of the entire process, reliable operation, convenient operation, and high efficiency.
