We are a big economic country. Under the condition of building a basic economy, a large amount of machine-made sand is needed every year. The establishment of a sand-gravel aggregate production line requires multiple crushing and screening to produce qualified machine-made sand.
First, the raw materials after blasting are uniformly transported to the jaw crusher by the vibrating feeder for vulgar operations. After simple crushing by the jaw crusher, the material is transported to the impact crusher or cone crusher by the belt conveyor for second. In the secondary crushing, the stones that meet the customer’s particle size requirements are transported to the finished material pile through the belt conveyor, and the stones larger than the upper screen size are returned to the impact crusher or the cone crusher through the belt conveyor to be crushed again, forming a closed loop. The current crushing modes include traditional fixed aggregate production lines and mobile crushing production lines. Mobile crushing production lines are the most popular equipment in recent years. There are tire-type mobile crushing stations and crawler-type mobile crushing stations. The mobile crushing stations are designed according to the needs of the site. The main advantage is the compact structure of the equipment, single or double crushing equipment can be configured, and the process structure is compact. In the case of realizing the task of fine crushing or sand making projects in large production capacity, the project investment cost and operation consumption cost are greatly reduced. Realize the cost-effectiveness of system project investment.
The mobile crushing station can turn the messy construction waste through automated sorting, crushing, screening and other processes into renewable resources that can be used for paving, construction, and municipal engineering. It not only solves the dilemma of garbage siege, but also eases the current situation of resource shortage. Restricted mining of river sand, high sand prices, mobile crushing production line has high crushing efficiency, low power consumption, strong adaptability, large crushing ratio, simplification of production process and saving investment.
