The acquisition of sand and gravel needs to be obtained from raw materials step by step. The bulk ore in the raw material bin is uniformly and continuously fed into the primary crushing equipment by the mine feeder. At present, the vibrating feeder is more commonly used in the mining industry, which is small in size, simple in structure, stable in performance and high in cost performance. The crushing stage is handled by a special coarse crusher and a medium and fine crusher (optional). The specific crusher should be selected according to the hardness of the ore. For ore with high hardness, it is recommended to choose extrusion-type crushing equipment, and for ore with medium hardness, it is recommended to choose impact-type crushing equipment. According to the demand of finished product specifications and the market trend, the sand and gravel production line can be equipped with a sand making machine after the crushing process, so as to further process the crushed stone material, produce machine-made sand that meets the requirements of the industry, and enrich the types and sales of finished products. The crushed or sand-making sand and gravel materials need to be screened. The vibrating screen has both screening and feeding functions, and can control the specifications of the finished products, and the quality of the finished products is good.
The
linear vibrating screen uses the vibration of the vibration motor as the vibration source, so that the material is thrown up on the screen, and at the same time moves forward in a straight line. The oversize and undersize of the sieve are discharged from their respective outlets. It has low energy consumption, high output, simple structure, easy maintenance, fully enclosed structure, no dust spillage, automatic discharge, and is more suitable for assembly line operations.
