subject: The Development Tendency Of Impact Crusher [print this page] The development tendency of impact crusher
The impact crusher has its distinct working mechanism and the structural design features. In the use of performance characteristics, compared with hammer crushers, impact crushers obvious have technical advantages. 1) The equality of the product size The material is in cube shape, with low content of fine powder and dust, especially suitable for vertical mill operation. 2) Low cost of operation and investment. Compared with hammer crushers, The total weight of the impact crusher is light, with small size of appearance and low static load value, can effectively reduce the cost of construction. At the same time, the power that motors need is low, which can effectively reduce power consumption and the running cost of equipment. 3) Fragile pieces of the impact crusher have long service life, and the cost for long-term operation is low.
Customers should have a comprehensive check for the motor and lubrication of the impact crusher after it has run for one week. The contents for checking include fastening situation of the fixed parts, bearing seals, counterattack liner and the abrasion situation of the liners. The users should also establish a regular maintenance and replacement system according to the maintenance cycle. The users should pay attention to the adjustment of the gap between the rotor and the impact liner of the impact crusher. When the rotor of the impact crusher is running, the gap between the rotor and the impact liner can not be adjusted. If the material in blocks strand between the back plate and the plate and shell, you had better lift slightly re-adjust the impact rack between the gap. In this way, the material will become loose, and it is easy to adjust the impact rack. If the impact rack is not enough, you can relax the lever on the tap.
The overheated economy due to strong consumption of people is called consumer-driven economic overheating; "investment-driven economic overheating", that is" excessive investment ", which contains two aspects of meaning:
First, after the completion of the investment projects, the products are not expected in the market demand, so product accumulated, the funds could not be recovered, resulting in a serious waste of the means of production. At this level, the "over" refers to the excessive demand for investment relative to the market.
Second, the spreading scale of investment is too extending, so that exceeding the capability of financial burden, and the investment can not be completed according to schedule, resulting that it could not form the expected production capacity. This level of "over" is the scale of investment relative to the excessive financial burden.
