Impact crusher stone processing technology to make a big step forward, the current impact crusher gravel production not only in quantity, quality can meet the construction requirements of each project, but also to adapt to the requirements of mechanized construction. But even the best machine in working condition in the long-term, together with other external factors, will cause the machine to a certain degree of wear and tear, so that work efficiency. So exactly what parts easy to wear it?
Impact crusher’s wearing parts typically include plate hammer, counter-liner, casing liner and the rotor body guards and so on. Where the board hammer wear failure shortest time, and wear and tear costs are also higher, therefore, reduce the board hammer wear is the key to solving the impact crusher wear.
Is what caused the wear of these parts of it?
First, the linear velocity. Line speed is the greatest impact on the operating parameters of the board hammer wear. The reason: the size of the line speed can directly affect the size of the plate hammer impact is applied to the material, size reduction ratio, and play a decisive role in product size. In addition, the line speed is too large may also cause the board hammer wear surge, it is because at high speed, the materials can not enter the impact area (or into a deep small), and ends with a hammer causing severe wear a. Foreign research data shows that: the board hammer wear and the line speed of a party to two power is proportional to the relationship.
Second, the ability to deal with the impact of the discharge gap. Impact crusher processing power also have some impact on the board hammer wear. When the processing capacity increases, product size will be thicker, crushing ratio decreases, the board hammer wear also with the lower unit net, too, to change the size of the discharge gap to some extent also change the size of the thickness of the product, it also has some influence on the board hammer wear.
The Affect of the material nature. Matters on the board to be broken hammer wear include: the nature of the material, feeding a particle size and moisture content and other factors, which influence the nature of the material to the maximum number, corresponding to different crushing material, the board hammer wear pure difference units great.
