Concrete is generally made of cement as a cementitious material, mixed with sand and gravel aggregates and water in a certain proportion, which is mostly used in the construction industry. The main source of waste concrete is the waste generated in the process of infrastructure construction such as house demolition and road maintenance. Concrete crushing is the recycling of waste concrete to realize waste utilization and save resources. So what's the detailed process flow of concrete crushing?
According to different production and processing requirements, fixed crushing production lines and mobile crushing production lines are generally used to crush concrete.
Fixed crushing production line process
The hardness of concrete is relatively high, so generally choose the crusher that can crush high hardness materials-jaw crusher and cone crusher. Firstly, the concrete is transported to the jaw crusher for primary crushing with a vibrating feeder, the big rocks are crushed into small rocks, and then the cone crusher is used for fine crushing. The crushed stones are screened and processed by vibrating screen, those that meet the specifications are sent to the pile by the conveyor, and the unqualified stones are transported to the cone crusher by the conveyor for crushing again. The particle size of the finished stone should be within the range of 0-5 mm and 5-10 mm.
The effect of primary crushing will directly affect the quality of materials, so the primary crushing equipment must choose the suitable equipment. Jaw crusher has a large crushing ratio, large output, and stable operation, which is suitable for crushing materials with high hardness. The finished product processed by the cone crusher has uniform particle size and a large output range, which is suitable for various large, medium, and small crushing plants.
Mobile crushing production line process
The flow of the mobile crushing production line is the same as that of the fixed crushing production line, and it is also composed of a vibrating feeder, crushing equipment, fine crushing equipment, vibrating screen, and conveyor. Firstly, the materials are transported to the primary crushing equipment by the vibrating feeder for crushing, and then the materials are transported to the fine crushing equipment for secondary crushing. The finished product can be directly transported to the material pile if it meets the specification of stone, otherwise, it needs to be re transported to the fine crushing equipment for crushing again.
Different from the fixed crushing production line process, the mobile crushing production line is a multi-machine integrated machine with equipment configured on the vehicle-mounted device. The whole machine is equivalent to a production line with a small floor area and no infrastructure piling is required. It can be moved at any time and can be directly driven to the operation site without transporting materials back and forth, which is highly intelligent, convenient, and suitable for users who need to change sites.
Nile Machinery can provide users with a more reasonable concrete crushing process. It produces a series of crushing equipment and auxiliary equipment in various types and complete models to meet the needs of different users, which can meet the needs of different users. And according to the actual situation of different regions and customers, we will have an in-depth understanding of raw materials and sites, and then arrange professional engineers to customize a reasonable equipment scheme and crushing process flow.
