In recent years, in order to protect river courses and improve the ecological environment, natural sand mining has been restricted and environmental supervision has been tightened day by day. The shortage of sand and gravel resources has become an indisputable fact. Since the production of machine-made sand is not affected by climate and seasons, and can be effectively controlled in the production process, it is favored by users and has become one of the projects invested by everyone. It is still very useful to enter the sand and gravel industry to learn about equipment production knowledge. Necessary, today we will take the production line with an output of 150 tons as an example to introduce the equipment in detail.
The machine-made sand production line with an output of 150 tons per hour is generally composed of vibrating feeders, crushers, sand making machines, vibrating screens, sand washing machines and belt conveyors. According to different process requirements, various types of equipment are combined to meet different process requirements. The following is a distinction between the material properties, and introduces two production line matching schemes with an output of 150 tons per hour:
Option 1: Belt conveyor + ZSW vibrating feeder + PC jaw crusher + PF impact crusher + VSI sand making machine + YKR vibrating screen + DXS sand washing machine = finished material
This scheme is suitable for rocks with a hardness below 250Mpa, such as limestone, dolomite, bluestone, etc. After the material is coarsely crushed by the jaw crusher, it is further crushed by the impact crusher, and then further shaped and crushed by the sand making machine to obtain qualified finished sand and gravel.
Scheme 2: Belt conveyor + ZSW vibrating feeder + PC jaw crusher + GPY single-cylinder hydraulic cone crusher + VSI sand making machine + YKR vibrating screen + LX sand washing machine + FG classifier = finished material
This solution is suitable for rocks with high hardness, such as cobblestone, granite, quartz stone, etc. After the material is coarsely crushed by the jaw crusher, it is further crushed by the cone crusher, and then further shaped and crushed by the sand making machine to obtain qualified finished sand and gravel.
