This is double rotor impact crusher rotating in the same direction, with simple structure, good performance and guaranteed quality. It is mainly used in crushing materials such as limestone, or plaster, especially suitable for cement factory. In the practical production process the bearing of impact crusher is easily to run into the inner ring or outer ring, which will result in the damage of shaft neck or shaft block. The staff must properly and timely solve this problem. There are many ways to deal with the trouble. Double-rotor impact crusher, for example, can be used the following ways such as surfacing, casement, thermal spraying, electric plating, sticky coating, etc. Different methods need different amount of manpower, material and financial resources. Of course, the results are also different. Henan Hongxing double-rotor impact crusher is designed through continuous innovation and absorbing international advanced technology, mainly used in crushing limestone, gypsum and other brittle materials, with high reduction ratio, low energy consumption and high capacity. What"s more we install a hydraulic coupling and opening device to reduce the starting load and protect the motor. Here we will introduce some methods to deal with the bearing problems. 1, surfacing: although there are kinds of surfacing electrode, its price is very high. If you choose inappropriate electrode or use improper measure, it will increase the cost and the difficulty of processing. 2, casement: it needs to calculate the strength and determine the minimum allowable diameter. Because the rotor system needs to be overall disassembled and processed by large-scale lathe. dryer machine:http://www.hxjqchina.com/product-list_35.html

Before turning, please strick the coating by using steel bar and evaluate the bounding strength of coating. The cost of spraying raw materials and turning processing is higher. 4, electric plating: select the right size according to the damaged axis standard, and brush with chromium plating or nickel. The processing time, the cost of raw materials and working hours is higher. 5, sticky coating: this process save time, manpower and coast. The thickness can be from dozens of microns to dozens of millimeters. But it should select accurate industrial repairing adhesive. It can basically meet the maintenance needs. Through the above introduction we can see that the sticky coating process has good effect and saves time and effort, which has been selected by the majority of crusher manufacturers. Hongxing can customize various types of rotors in line with actual crusher types and clients’ requirements to be applied for various hammer crushers. Crusher Rotor is the key component of crusher. After long time use, the hammer pin is likely to be out of shape, and the hammer plate and hammerhead are likely to break. All these problems have been completely solved.
