As one of the most important operations in aggregate process, crushing is a process of suiting customer’s requirements by breaking and shaping mine rock or other stones to reduce their size for further processing. Generally, there are more or less three phases: primary crushing, secondary crushing and tertiary crushing. The primary crusher(usually jaw crusher, sometimes impact crusher, it depends on your material type, size, hardness, etc.) reduces materials from under 1.5m to under 0.3m; For further size reducement, secoondary crushing can help you reach below 40 or 50mm, and in this step, cone crusher is usually employed in consideration of product size and shape. When it comes to tertiary crushing, material size is generally reduced to below 20mm.
There are main four production lines in crushing: Stone production line, Sand production line, Grinding line and Ore dressing line. For those production lines, mining equipment are important. The mining equipment are the main equipment in our company. We do not only supply single device, such as feeding machine, crushing equipment, conveyors, screening equipment, classifiers, ore washing equipment, grinding machine, preparation equipment and dryer, but also supply the design of a whole production line, such as stone production line, sand production line and mineral production line, which consists of the former equipment.
Process of Stone Production Line
Big size stones are transferred to primary crusher through vibrating feeder from hopper for the first crushing, then the crushed materials are transferred to impact crusher through belt conveyor for the secondary crushing. The materials crushed will be transferred to the vibrating screen, and separated to different sizes. The aggregate with suitable size will be transferred to the final product pile and aggregate with unsuitable size will be transferred to the impact crusher for re-crushing. This forms a closed and manifold cycles. The sizes of final products will be graded and separated according to customers’ requirements, and the duster will be attached for the sake of environment protection.
Process of Sand Production Line
The raw material is transferred to jaw crusher for primary crushing by vibrating feeder, then the crushed material is transferred to sand-making machine through belt conveyor for secondary crushing. The materials crushed will be transferred to the vibrating screen. The material with suitable size will be transferred to sand washing machine, after being washed, then clean final products will be discharged. The other material with unsuitable size will be screened from vibrating screen, then will be transferred to the sand-making machine, this forms a closed and manifold(many) cycles.As a professional and the best mining machinery manufacturer in China, Hongxing Machinery is always ready to provide the superior teeth roll crusher, rock grinder, and these machines have the most competitive price and the most reliable quality so that they are the top choices for the high performance crushing equipment. - https://www.affordablecebu.com/
