sand making machine in the market, many in the actual production because of the design as well as the selection of the restrictions on the number of features is imperfect, and will advance many times that there is no normal operation, thereby increasing the production loss, the loss will relatively high. Some customers choose their own production sand washing machine, sand making their production course to meet their production needs. But in the agency made ​​to wash sand incomplete understanding of the situation, perhaps not only increased the number of unnecessary structures invested capital, and will be more, thus increasing the number of unnecessary power loss. Green mine construction is that the people in the development of mineral resources is necessary to achieve maximum utilization of resources, but also to achieve the impact on the natural environment is minimized, ensuring a harmonious local cultural environment, improve the material and cultural living standards of local residents. In recent years, the national economy through various channels, and actively enhance the competitiveness of the region's economic development, various provinces have continued to increase investment in infrastructure.

China's economic growth rate accelerated in recent years, do not continue to improve urban and rural facilities, construction of roads and other infrastructure, making the demand for various types of construction sand and gravel also continued to rise, while promoting infrastructure development that has Sand making machine become an indisputable fact that, under the impact of the national policy, infrastructure needs for artificial sand and gravel aggregate increase, let sand making machine welcomed. In efficient sand washing machine to clean quartz sand, which features a tank, opened the top of the tank out of the discharge port, equipped with the material inlet and outlet closures, the lower tank has a filter, tank upper convergence sour lotion into the tube, the tube and vacuum pumping waste straw, acid liquid into the pipe, tube and vacuum pumping wastewater out on straw-off valves are located about the acid liquid into the tube and peripherals pickling phase supply equipment, vacuum vacuum suction pipe and the peripheral contact on the lower portion of the filter body of the adapter tube, and an acid wash of the reverse cleaning liquid into the tube, the reverse cleaning liquid into the tube in contact with the high pressure pump, said tank body wall to mezzanine layout, mezzanine equipped with heating equipment. The utility model compared with the conventional skills, is dissolved in the solution can be useful to leave impurities, undoping speed, purified natural quartz sand, the output may be high purity quartz sand, the impurity content can be reduced to the quartz sand less than 20PPM, quartz sand sand washer equipment can be used to produce after the disposal of semiconductor grade quartz additional information.

Sand is a widely used in granite, limestone containing more clay content of sand and gravel washing, separation and removal of mud sand washing equipment, into a single spiral sand washing machine and double spiral sand washing machine, in which a single spiral sand washing machine and double spiral sand washing machine they were different models to adapt to different operating conditions. In general, the spiral sand washing machine wash pressure within a range of 145pa to 198pa, the use of the buoyancy of the water pressure range, and the dust and impurities are separated from sand and gravel material, and then the agitation of the helical segments, filter to remove impurities to achieve the effect of water, and then after washing the sand and stirred to make the finished crushed gravel evenly through the material of the conveyor belt. Spiral sand washing machine is arranged in the formation of sink lower inclined sedimentation tank, screw head is immersed in sedimentation tanks, spiral by the motor through the gear reduction drive screw rotates, the bottom of the settling tank to the wash water, thus completing the cleaning, dewatering and classification of three functions. A spiral blade mounted on a central shaft by a gear connected to the central shaft work. With different proportion of solid particles, and thus different sedimentation velocity in a liquid principle, be a mechanical grading equipment. The main structure of spiral sand washing machine includes tank, reducer, motor, central shaft, helical blade, frame components. After welding the center axis of the stent, the helical blade 安好 clamping bolt, deformation of the blade does not sag. Meanwhile spiral sand washing machine water can be recycled, saving water resources, to achieve a green path.
