Sand making machine, also known as impact crusher, referenced the United States crusher principle and technology, combined with the actual situation of the diversity of sand production, research and development to a domestic and international leading level, crushing equipment. It is widely used in all kinds of rocks, abrasives, refractories, cement clinker, quartz, iron ore, concrete aggregate a variety of hard, brittle materials crushing, fine (sand). On the road building sand, sand stone is particularly suitable for.
Advantage of sand making machine
The unique feed crushing structure, has a variety of crushing cavity, to achieve the “stone dozen stone” and “stone timbewolves” free conversion, more of the finished products is excellent grain type, gradation and reasonable, improve the work efficiency.
Equipment installed over the vibration display and alarm device, if the device has a bad operation, you can issue a warning, so that the equipment to stop working, to protect the purpose of the machine.
The finished product is cube, with good grain shape, reasonable gradation, adjustable fineness modulus, and is especially suitable for artificial sand making and stone shaping, and the effect is improved by 30% compared with the traditional equipment.
Inside the eddy current chamber with a unique air self circulation device, thereby reducing the exhaust air rate and configuration of a variety of specifications for the dust removal equipment, little dust, low noise can not only reduce the dust pollution, but also can improve the work efficiency.
Working principle of sand making machine
Emission from the top to the ejection velocity into the middle of consist of material in the hopper into the sand making machine, the distributor of the material is divided into two parts, one part is composed of a feeder of high-speed rotation of the impeller, the impeller is rapid acceleration, the acceleration of up to hundreds of times the acceleration of gravity, then to 60-70 meters / seconds from the impeller three uniform flow out, first with the feeder surrounded by self closing down a portion of the material crushing, and then along with the impact of the branched vortex cavity material lining layer, is the material lining layer rebound, oblique impact to eddy cavities, and change its direction of motion, partial to sports impeller out of the material to form a continuous material curtain. Such a piece of material in the vortex of the broken cavity by two times as well as multiple probability impact, friction and grinding and crushing. The broken material is discharged from the discharging port of the lower part. In the whole breaking process, material mutualselfimpact crusher, and metal elements in direct contact, but with the material lining layer of impact, friction and grinding. This reduces the angle pollution, prolong mechanical wear time. The clever air circulation in the vortex chamber eliminates the dust pollution.
