Although the sand in front of the factory has been running for 8 hours time and space to adjust the load, all of them were normal, but in spite of such words in the sand on-site installation should still conduct a comprehensive inspection. The main check the oil pipe is connected securely, once again add oil, in check the component connection, carefully check the impeller is caused by a foreign body, check the motor connections, the applied voltage is normal. Before installing the belt to move the third generation of Sand, Sand confirm signs consistent with the direction of rotation direction of rotation in the opposite direction is prohibited. After confirmation, in pre-production first empty load and load test machine, confirmed there is no problem and then carry out the actual production. Empty load operation requires four hours of time and then to load operation, load operation time takes more than eight hours time. Sand, also known as impact crusher, companies use the US Bamako famous "rock stone" crusher working principles and production technology, combined with sand production technology at home and abroad to develop out of the situation with the international advanced level of stable performance, low emissions equipment, its performance in a variety of fine ore broken equipment is irreplaceable, and most effective, practical and reliable. The crusher is used in construction sand, road sand, asphalt concrete and cement concrete aggregate ideal production equipment, it can be used for transportation, construction, etc; in the field and is an indispensable machine. It is suitable for crushing soft or medium hard and extremely hard materials, plastic, widely used in a variety of ores, cement, refractories, aluminum where the soil clinker, emery, glass raw materials, mechanism building sand, stone and various metallurgical slag, Sand is widely used, especially for silicon carbide, carborundum, sintered bauxite, the US high sand hard, special hard and corrosion-resistant material than other types of crushers yield effect. Our production of river gravel sand than in accordance with standard production, but also based on user usage, designed and manufactured according to user needs, to play the best performance in a production environment of use, thereby reducing failure, maintenance frequency, greatly improving productivity and higher profits for the enterprise. Having said that, our river gravel Sand in the end what are the characteristics of it, first of all our Sand simple and reasonable structure, independent break vsi sand making machine, ultra-low cost of use. And has a unique spindle bearing installation and advanced design, with heavy-duty and high-speed rotation features; with crushing, coarse grinding function, resorted to a small particle size, particle uniformity of production capacity; we can not ignore the security problems in the production process High Our production of river gravel crusher reliability, tight security means new Sand, running and steady low noise, high crushing efficiency saving universities, and to ensure that the personal health and safety equipment and operating personnel.
