subject: How To Lower Impact Of Sand Making On Environment [print this page] Environmental protection is China's basic national policy, and engineering needed for the building of artificial aggregate production, first of all should be designed to give full consideration to choose environmentally-friendly technical solutions, to make full use of the concrete aggregate excavation spoil useful material processing to minimize the mining of mountain farm materials, resource development tends to harmony and unity with the natural environment.
In project construction, it often requires mining mountain farm materials for the processing of concrete aggregate. In the process of mining, processing and easy on the natural environment and human production, damage and harm the living environment, including materials mining on vegetation and slopes of physical security and stability destruction, crushing the dust generated in the screening process, noise on the environmental impact of air quality and human survival, as well rinse screening of wastewater, waste residue of rivers, valleys, land of the natural environment caused by the impact.
Processing capacity is greater than the aggregate processing system of 500t / h, from the wool of the mountain farm mining generally need at least after three broken three screening only after grading out to meet the requirements artificially graded gravel and sand. Aggregate crushing and screening process, in order to ensure the finished aggregate quality and reduce processing costs, is generally based on the processing of raw material characteristics and the size of the different processes of production of all dry and wet production or a combination of two processes.
Sand and gravel processing equipment, most of the strong sources of noise and dust source on the surrounding environment pollution, the threat to the health of production personnel, should be given due consideration in the selection of equipment and technical design.
(1) the choice of the crusher, shall meet the crushing process to determine the ratio under the premise of similar equipment, try to choose low center of gravity, the small magnitude of the rotor or convergent plate movement, excellent protective performance of equipment, from the source of noise to a minimum.
(2) shaker to ensure that the screening efficiency on the basis of the screen try to choose a good damping effect of the polyurethane mesh.
(3) in the system planning stage, we must proceed from the concept of environmental protection, the location of the system to choose a place far from the office and living facilities and residential areas, crushing and screening workshop at the same time as we choose in the cove area to avoid dust and noise diffusion.
(4) of the equipment placed at the foundation should be designed to reduce equipment vibration of the structure, or using new materials conducive to the weakening of the vibration of the device.
