In the construction of hydropower / mixing station, road construction technology of artificial sand making machine gravel production systems are in use in the 20th Century Sand production process 60-70 years, the use of foreign advanced equipment for sand only in large-scale hydropower projects, sand produced by the domestic sand requires certain parameters with natural sand production in order to meet current quality requirements, and for the use of foreign sand making equipment, but the specifications of the finished product abroad is too large, no longer applicable to the present domestic use material requirements. The rod mill is applicable with increased production costs, the loss of a large quantity of fine sand, steel consumption volume and serious environmental pollution problems, while Henan Yuda developed by PCL sand making machine is a new efficient Sand , produced by the fineness of the sand are much higher than the water conservancy project requirements and good grain shape. Material can be washed and cyclones treatment, to ensure cleanliness of materials to ensure the supply of aggregate demand to ensure high-speed railway, highway, water conservancy and other construction sand and gravel aggregate production use.

On the production line on Sand Creek Sand Pebbles purchase and the entire production line is equipped should have a clear understanding of when buying Sand or gravel entire production line, most manufacturers have preferred to ask is what the material? Finished need much? The size of the raw materials? Therefore, only for the fight have some knowledge of the material to be more explicit and clear, and to choose their own Sand, sand machine, river gravel Sand, and now more popular mainstream configuration generally consists of: Mine shock to feeder, jaw crusher, impact crusher, sand making machine, vibrating screen, sand washing machine, and other mainstream configuration, and for different materials must also equipped with fine break, cone crusher, spiral stone washing machine, for not washing venues also need to increase the cyclone to replace sand washing machines and other related equipment. Sand production line mentioned above are not suitable for all customers, large gravel plants and materials for hardness is not too high, you can wash the sand two thin broken lines and cone crusher can break counter-breaking, etc. removed, can be broken by rough broken (broken jaw) had later transported directly to the crusher, sieving through a sieve, or by washing the cyclone can be processed. Not only can a small section of unnecessary equipment budget may also meet the requirements of the ideal materials, and for high strength materials can not hold (to save the province) attitude, although the increase is necessary to increase the budget of a machine, but for the whole crushing ratio, the division of the material for each machine to achieve optimal production results.

Bearing is an important component Sand equipment indispensable equipment in Sand play a huge role in how to properly care for Sand bearing reasonable to make it play the greatest role. Sand bearing lubrication proper viscosity lubricant should be used to improve lubrication. Sand pairing rolling bearing parts of the surface finish to teach poor. Foreign objects into the lubricant easier adhesions. A suitable lubricant should be selected.
The lubricant improper use or non-locking and less there will be a bad situation in a timely manner, Sand bearing shaft deflection big rust, corrosion, check the accuracy of the shaft and bearing wear and indentation point. Pressure ball machine load bearing inner ring rotates, the outer ring raceway or rolling decent showing scaly rolling fatigue spalling. Sliding surface portion of the so-called card injuries resulting from minor burns summary of surface damage resulting damage. Lubricating a surface roughness caused by the difference. Is not appropriate to release the lubricant. Lubricants and to improve the methods.
