Sand production line often used in a lot of broken equipment, mainly sand making machine its role is different in different species, a complete sand production line requires the joint coordination and cooperation of various equipment, the team's strength is the most powerful and the most infinite the. Sand production line will be used jaw crusher, impact crusher and other equipment, using any device has certain skills, following the relevant technical knowledge crushing equipment for detailed analysis and presentation.

Use sand production line running from, due to the characteristics of the equipment devastating sandstone, wearing parts replacement cycle is short, high-cost, high moisture content of finished manufactured sand and gravel production efficiency sand making equipment to make a greater impact from the current sand making equipment, mainly destruction machine for vertical shaft, holding a hammer mill and Sand. Destruction machine into a vertical shaft sand is higher than 0.8, generally around 0.6 mill holding, hammer crusher at 0.7 to 0.8, but the powder content of about 30%, and can not wet sand. Its economy, scroll destruction machine is better than holding the mill, but no holding mill grading system is good. But the sand technology trends, in order to break instead of grinding efficiency is remarkable because of its great economic potential to replace, domestic and imported equipment performance equipment performance gradually close. But because much of sandstone as a raw material, there is no device more suitable sandstone sand, sand to reduce costs.

Using vertical shaft impact crusher sand material sources of sensitive water content, water content, the higher the efficiency of the system, the lower sand when wet sand, sand bunker adjustment setting unloading car or reversible belt conveyor stacker multi-point , recycled material source, so that the material has some drying time, reduce the water content of the material source, increasing the efficiency of sand. On the other hand, due to the sand sandstone high performance requirements for equipment, consumable replacement cycle frequency too, must seek Study of a wear-resistant material, sand solve vertical shaft liner, or affect the normal continuous operation of the entire system.

When sand production line jaw crusher rotation, working resistance power and drive power for most jaw crusher can not remain equal in any instantaneous; function when power is greater than the resistance power, the spindle speed increases; otherwise reduce . At this rate fluctuations will affect the production process, causing the elastic vibration, reduced power consumption and more efficient machinery, and even affect the strength of the member. Therefore, the resistance was a period piece work or aperiodic changes in sand production line, dryer manufacturers to solve the speed problem.
