Introduction of molding sand production line equipment
1, jaw crusher
Jaw crusher has super crushing force and crushing wall, combined with its high wear-resistant lining, it can handle a variety of ore materials, and users don't have to worry about the problem that ore materials can't be crushed because of too high hardness. In the crushing process, not only can the maintenance cost be effectively reduced, but also the failure rate of the equipment can be reduced, and the operation is more reliable.
2. Impact crusher
Impact crusher belongs to the principle of impact production. The produced machine-made sand has good particle shape and simple particle size adjustment, only the gap between the impact plate and the plate hammer needs to be adjusted. The impact crusher is easy to operate and is usually used for secondary crushing, which is convenient for sand making machine production and meets the demand of stone production.
3. Sand making machine
At present, the common sand making machines are HVI sand making machine and VSI sand making machine, each with its own advantages and characteristics. The lubrication scheme and throwing head of HVI sand making machine adopt modular design, and the peripheral guard plate can also be replaced to prolong the service life of parts; VSI sand making machine has good use effect, low investment cost and high production crushing efficiency. The crushing cavity used is stone and iron.
4. Sand washer
The sand washer is responsible for cleaning machine-made sand, removing dust and impurities covering the surface of machine-made sand, and improving the quality and gradation of sand and gravel. The sand washer has simple structure and low failure rate, and can effectively improve environmental protection efficiency.
5, vibrating screen
Vibrating screen can screen machine-made sand into finished products with different particle sizes and specifications, and can also be used with sand making machine to form a closed cycle. The vibrating screen equipment can design the number of screen layers according to the production requirements, and there are almost no other wearing parts except the screen, so it is simple to maintain and use.
6. Feeders and conveyors
Feeder and conveyor belong to the auxiliary equipment of sand production line. The feeder is responsible for the feeding of sand and gravel, which can avoid the phenomenon of equipment blockage, and the conveyor is responsible for the transportation of materials and the transportation of sand and gravel to the sand making equipment.
Process flow of sand production line
The mined natural stone is uniformly and continuously sent to the jaw crusher of the coarse crusher by the vibrating feeder for preliminary crushing, and the generated coarse material is conveyed to the impact crusher by the belt conveyor for further medium crushing; The crushed stones enter the vibrating screen to screen out two kinds of stones, and the stones that meet the requirements are evenly sent to the sand making machine to make sand, and those that do not meet the requirements are returned to the cone crusher for crushing; Qualified sand is sent to the sand washer (optional) for cleaning, and the cleaned sand particles are sent to the finished product pile for packaging by the conveyor to produce various sand materials that meet the requirements.
