Vertical shaftis also called sand making machine, is the combination of domestic sand production in terms of the actual situation, developed with the domestic, international, the leading level effective crushing equipment. It is widely applicable to a variety of rock, abrasives, refractories, cement clinker, quartz, iron ore, concrete and other hard, brittle materials in pieces, fine ( for sand ). For construction sand, gravel roads excellent for the appropriate use. By feeding, distributor, swirling crushing chamber and is composed of seven parts.
Vertical shaftworking principle
PCL vertical shaft impact crusher, also called PCL vertical fine crushing machine, also called sand making machine, is a kind of equipment. PCL vertical fine crushing machine is currently the world’s widely used to replace cone crusher, roll machine, ball mill, and has the advantages of reasonable structure, convenient disassembly, high crushing efficiency. The PCL crusher discharging granularity is between 3mm-8mm, the particle size of fine and uniform, and the durability of components, less wearing parts, maintenance convenience. Energy consumption than the traditional crusher, low energy consumption, hourly capacity of 30-130 tons, production capacity.
Sand making machine principle of work:
Material from the hopper into the crusher, the distributor of the material is divided into two parts, one part by distributor intermediate access high speed rotating impeller, the impeller is quickly accelerated, the acceleration of up to hundreds of times the acceleration due to gravity, and then to 60-70 M / s speed from the impeller three evenly distributed within the flow passage of the projectile out first of all, with a distributor since the resumption of falling around a portion of the material impact crushing, and then with the impact to the vortex branch cavity material liner, was material lining layer rebound, oblique shock to the vortex chamber at the top, and change its direction of movement, a deflecting movement from the flow passage of impeller, fired material form a continuous material act. Such a piece of material in the eddy broken cavity by two and many probability impact, friction and abrasive crushing function. The crushed material from the lower discharge outlet. And cyclic sieving system form a closed circuit, general circulation three times can be broken into 20 heads of the following materials. In the whole process of material crushing, mutual and automatic impact crushing, not in direct contact with metal components, but with the material liner impact, friction and grinding, reducing the angle of pollution, prolongs mechanical wear time. Vortex cavity internal ingenious air circulation, eliminates dust contamination.
Vertical shaft impact crusher working performance
PCL series vertical shaft impact crusher is mainly composed of a motor, a hydraulic cylinder, the lining plate, rack, crushing cavity block, back, throwing wheel device, damper, gas station, spindle, platform. Material directly into the high-speed rotation of the impeller, under the action of centrifugal force, and the other part with umbrella form shunts in the impeller is surrounded with material impact, the material in the impeller and the casing form vortex type multiple collision, friction and grinding, forming a closed circuit crushing cycle cycle. Finally, the material sieving control to achieve the required finished material granularity.
Vertical shaft impact crusher application

Vertical shaft impact crusher working characteristics
The simple structure
Vertical shaft impact crusher
Vertical shaft impact crusher ( 15 pieces)
, low cost and. The high efficiency and energy saving, high crushing efficiency. It has a fine, coarse grinding function. And through a broken material capability, small influence by material moisture, moisture content of up to 8%. But the crushing of hard, hard material ( such as corundum, sintered bauxite etc. ). The product is a cube, iron pollution. ⑺impeller and eddy broken cavity lining materials since to substantially reduce the cost of wear parts and repair work. The operation and repair, convenient installation, the work noise less than 75 dB ( dB ), and have light weight, installation modes, movable installation etc..
Sand making machine features:
1) the machine is a new development in the ninety’s, fine crushing equipment, is currently the world’s widely used to replace cone crusher, roll machine, ball mill.
2) novel structure, unique, stable operation.
3) small energy consumption, high yield, big crushing ratio.
4) equipment has the advantages of small volume, simple operation, convenient installation and repair.
5) with shaping function, a cube-shaped products, bulk density.
6) in the production process, the stone can form a protective bottom fuselage, no wear, durable.
7) a small amount of easy to wear pieces with hard and wear-resistant materials, small volume, light weight, easy replacement of parts.
