Counter-crusher is often used in the two or three sections of the gravel production line, which is common in the entire crushing line, which is closely related to its technical characteristics, cost and yield. In particular, the new European version of the Impact crusher in the automation of intelligent technology breakthrough, it is greatly enhanced the efficiency of gravel production. Gravel production line is the rock, gravel, river pebbles and other materials made in line with a variety of sand requirements of the process, gravel production line prepared by the gravel material with uniform size, high compressive strength characteristics, compared to natural sand and ordinary hammer Sand produced by sand production more in line with modern industrial, construction and other requirements of the sand. An efficient gravel production line can not be separated from the performance of reliable and efficient granite production equipment. Generally include crusher, sand making machine, belt conveyor, vibration feeder, sand washing machine, circular vibrating screen and electronic control equipment. Among them, the quality of gravel material is broken crushing equipment. The new European version of the Impact crusher in the application of gravel production line, directly improve the entire production line of automation. The new Impact crusher is Shanghai Shi Bang in the traditional impact crusher on the basis of improved products, especially for its automation improvements, greatly improving its production efficiency. The state expert has optimized the internal structure of the crushing chamber of the counter crusher and placed the sensing device at the inlet and outlet. And then enter the software database, only start and end the work requires a certain amount of manual intervention, the rest of the time can be self-control. Thus enhancing the stability of the operation of the equipment, timely detection of problems, reduce the incidence of failure, the most important thing is to greatly improve the Impact crusher and the entire production line of sand production efficiency and production. In addition to the advantages of high degree of automation, Impact crusher used in gravel production line, you can also expand the production line of materials to adapt to the scope of a multi-purpose machine to increase user income; Production has a higher feasibility; its wear-resistant pieces of hard material, the number of wear parts also decreased, and the purchase cost is also low, so its maintenance costs are relatively low, help to improve efficiency; impact crusher Processing of sand and gravel material is very perfect, directly improve the production line of the finished product level, use more widely.
