The production process of aggregate and water conservancy engineering

In the super size processing (or crushing jaw crusher) selection, the load coefficient 0.65-0.75; vibration sieve and broken (crusher), fine (cone crusher) workshop with two shifts, the load factor of equipment to be 0.75-0.85, sand making machine, with stable production quality requirements, to work with three consecutive shifts, the load factor of equipment to be 0.85-0.9. Aggregate production process is typical: semi-finished production - stone production - sand - water use and wastewater treatment. This product is refers to the artificial aggregate block (egg) Ishihara material by crushing of the product, the maximum size of the general control in the broken machine allows maximum feed particle size. According to the terrain conditions and production, should be in the coarse crushing equipment after or in between the two crushing and screening equipment, set the half finished product storage yard, adjusting the bin can also set a smaller capacity. The crushing plant products transport to the screening, re screening classification, and the excess aggregate transport again to crushing workshop processing cycle path. In the design of artificial aggregate processing system, the general configuration of cone crusher and impact crusher, sand making machine at the same time allocation, gravel and sand at the same time, is the cone crusher and crushing stone available after vibration sieve to sieve piled up, another part can be transported to the sand gravel machine made sand, two sand can be configured according to a certain proportion, but also can be stacked separately, so as to improve the production efficiency.

Device options crushing is artificial aggregate production equipment of the civil engineering, the largest amount of investment, most of the process. Crushing machine inlet size, should be in accordance with the loading machine hopper, feed particle size should not be greater than 0.85 times the width of the crushing machine imported. Crusher type, to adapt to the request and physical properties, processing stone crushing capacity, crushing product grain size and requirements of the equipment, the use of impact crusher (sand making machine) and crusher good grain.
