(1) an increase in the basis of the third generation of Sand on the counterweight wheels, so saving energy counterattack Sand, an increase of kinetic energy. Production efficiency has been greatly improved. Increases the back plate adjusting device so adjust the fineness is more convenient, without opening the case, you can adjust the vsi crusher, two were designed back plate adjusting device, eliminating the hassle of using a crane. (2) the old third-generation Sand observed only rear door opened. The new sixth generation of Sand on its side also opened the door to observe maintenance. This is more conducive to the functioning of the maintenance and observation equipment. (3) In the grate regulating device added on both sides of the back plate material, with multiple functions crushed material, so that the material for grinding in the crushing cavity, crowded, collisions, resorted to a higher rate of sand, and with a shaping role to make better and more uniform particle type sand Sand, another more convenient adjustment of the expected size of sand .. design more humane. Due to the time of impact crusher and counterattack Sand appear different, Impact Sand (2003), the third generation of Sand (2005) So, we call the second generation of Sand and the third generation of Sand, in fact they are different works are very efficient sand sand making equipment. Currently more manufacturers say that the fourth generation of Sand, the fifth generation of Sand, Sand sixth generation, the seventh generation of Sand and so on, in fact, not so much Sand. Sand only: Impact Sand, the third generation of Sand and rod mill Sand. Troubleshooting edit Sand is not in there when the material started running, if doing so would start because the pressure is too large and the motor burn out the motor. In addition there will be damage in other areas. So be sure to pay attention to the order of operations when the crusher is to start crusher, then fill join raw ore. Are there any crusher its scope of application, Sand Sand is the same factory, which requires adding to the size of the ore material which can not exceed a certain size, if too large, will make the raw ore to plug in Sand inlet. Then because of the need to clean the machine ranging from the impact to production, while it will damage the impeller because the stone is required to use the service. Machinery and equipment are to be maintained, otherwise the machine wear each other within the iron is very easily damaged. Sand in the application of a period of time necessary to check whether the need to add oil, so as to make the machine more long-term use. Sand is held together by screws, often strenuous exercise these screws will loosen. If abnormal Sand Henan powerful ring during use, it is necessary and timely shutdown for inspection. Find the cause of ring and tighten. Sand, Yuxin Senda (certified), Maoming Sand provided by Henan new Senda Heavy Machinery Co., Ltd.. Henan new Senda Heavy Machinery Co., Ltd.
