Sand making machine safety knowledge

Upper bearing spindle assembly for swimming side, the bottom bearing is fixed end, pulled by hand after assembly pulley should be flexible rotation. In Sand operation, because of the equipment belongs to the high-speed equipment, special attention should be safe production. Relevant personnel should stay away from equipment, machine repair on For after the shutdown should be. Problems we recommend that you ask a professional maintenance staff to resolve without permission is strictly prohibited dismantle factory core components. Improve the stability of the impeller means to extend the life of Sand. At this stage, due to the project by increasing the amount of sand, sand mining operations led to the supply of natural sand and gravel aggregate is difficult to meet the market demand. Therefore, sand or artificial sand making machine equipment industry gradually on the rise, and bring the whole construction machinery industry for heavy mineral processing equipment and process technology research and improvement. Sand and gravel production line as an important part, because of its important role in the whole mechanism of sand production, so the stability and durability of its components becomes important. The industry believes that Sand play a decisive role on the material jet impeller means is an important component, which determines the stability of the work associated with conveyors, feeding machines, sorting machines and other work efficiency. Impeller work characteristics The impeller is an important part of the Sand, but also a part of the most vulnerable, because the material is dispensed in the launch of the impeller in complete, if done incorrectly, can easily lead to material wear impeller, so we should be in a specific work and operations be careful to avoid because carelessness, thus triggering a series of careless accidents. We know that the impeller shaft mounted on the upper end of the spindle head assembly, passed away with tapered sleeves and button key connection, high-speed rotation, while the central portion of the material from the impeller feeder feeding tube into the center of the impeller. By cloth cone impeller center will even assign materials to each impeller flow channel launch, the launch channel outlet mounted wearable pieces made ??of special materials can replace the impeller will accelerate to a certain speed projectile material out, the impact of the vortex moving crushing cavity lining materials, conduct intense self crushed between the impeller equipped with the cone hat and wear blocks, indecent channel plate, thereby protecting it from wear and tear. When the front of the device to stop functioning should be noted: Before stopping the discharge device first stop feeding, feeding should be continued uniform, strict compliance with the requirements of the specifications of materials, or materials is also very easy to wear because of the impeller. Under normal circumstances, sand making more use of single motor drive or dual motor drive belt transmission mechanism (75kw or more, for the dual-motor drive), dual-motor drive two motors were installed on both sides of the spindle assembly, two motor pulley belt the pulley is connected with the spindle, the force balance on both sides of the spindle, no additional torque.
