Feeding system This system is to send raw materials to each section of crusher equipment and screening machine, according to the crushing and screening process. The equipment that completes the feeding process includes vibrating feeders or other types of feeding equipment. In the stone production line, the feeder equipment is generally used to be responsible for the supply of stone. Second, the crushing system The system is the core of the whole set of equipment. Its job is to crush various ore raw materials into finished materials of required particle size, and a combined stone production line can be composed of multiple crushers. These crushing machines have different properties and work together to complete the crushing of stone. 3. Screening and conveying system The system is to screen the crushed ore by a screening machine. In the sand and gravel composite production line, the sand and stone need to be separated, and the graded sand and gravel need to be transported to their respective sites. The equipment used in this process is generally a linear vibrating screen or other screening machinery.1. Strong flexibility: The machine is free to set up and move easily, and it can directly penetrate into the production site, and the operation and operation are very flexible and convenient. 2. Reliable quality: excellent material selection, advanced technology, more stable equipment quality, and more than 3 times longer life than other equipment. 3. Green environmental protection: The crushing process can completely reduce dust, noise and other pollution to the standard range, fully comply with relevant regulations, will not cause pollution to the environment, and achieve green production. 4. Low cost: less faults, stable operation, safe and reliable, the overall cost is reduced by about 400,000 yuan, and the structure is simple, reducing the complicated steel frame structure, further saving basic funds of 30,000 yuan.
