Machine-made sand production line is a kind of equipment of sand machine-made sand production line, which arises from modern aggregate production. Its equipment includes jaw crusher, cone crusher, impact crusher and belt conveyor, vibrating screen, sand-and-stone washing machine, etc. Its working principle is to use high-speed rotation. The plate hammer installed on the machine can crush the material, and the friction between the materials can also accelerate the crushing of the material. The sand making machine is suitable for crushing and fine crushing of harder, medium-hard and worse abrasive materials. The fineness of the sand products can be adjusted according to the need. However, few people know that the way of sand and gravel feeding has an impact on sand production. The sand machine is one of the core equipment in sand and gravel production. What are the feeding ways of the sand machine?
In the feeding of sand making machine, there are generally two ways: one is the full-center feeding mode, which ensures the same size of the impeller feed. When the material flow into the impeller reaches a greater operating load, the re-feeding material enters the outer side of the impeller through overflow, making full use of the impeller and the eddy. The crushing of dynamic crushing chamber. In addition, the feeding mode of central feeding accompanied by circular waterfall can also be adopted. When the feeding size is larger than that of impeller feeding, two feeding ports can be used to feed. The work of sand making machine is to use the whirlpool of high-speed rotating impeller and blade to ensure that the material has greater impact ability, change the direction of material falling, and form a continuous flow. Sand production reduces the wear of equipment, greatly improves the efficiency of equipment, reduces energy consumption and equipment consumption.
The feeding mode of sand machine is different, and the production efficiency is different. Therefore, it is necessary to consider comprehensively according to different material and product objectives. Jaw crusher, impact crusher, sand machine, sand washing machine and belt conveyor are all important production equipment in the production line of machine-made sand.
