Overview------PLF sand making machine:

1. Sand Maker (Vertical Shaft Impact Fine Crusher) is offered by Our Research Group Based On the Construction Industry Traditional Sand Making Equipment Directed at the drawbacks and disadvantages and Absorbed the advantages Depending on the Advanced Crushing Theory and Many Tests.

2. It Includes the Advantages of Hammer Crusher, Impact Crusher and reaction Crusher but is different from Them. So it is the perfect Combine of that Crusher and it is Character Extensive Use, Less Wearing, High Ratio Crushing, Convenient to Maintenance and so on.

3. And it makes Cubic materials, Less Acicular and Schistose Materials, So It is especially Suitable to materials bettering, Sand Making. Then It is the Ideal Equipment in Construction Industry, Cement and Mine Selection .

Advantages------PLF sand making machine:

(1) Working reliable and stable

1 The working principle of PLF sand making machine

PLF sand making machine use the advanced crushing principle of selective crushing and cleavage crushing, add enough kinetic energy directly on the raw material and then through striking put the kinetic energy into the crushing energy to crush the raw material.

(2) The Low consumption of quick –wear part

The best design of crushing cavity angle for the material to impact , little fraction with the quickwear part ,and the operation cost is 30% lower than the traditional equipment. It can directly decrease the equipment operation cost .

(3)Automatic detection to make it safe and reliable

There are device to show vibrating speed beyond the equipment and warning .If the badness operating happened, the equipment can be stopped through the warning to protect the equipment.

(4)Easy maintenance

The hydraulic open cover device can make the internal parts of the crushing cavity maintain and repair easily , it short the machine halt time and save time and energy .

Usage------vertical sand making machine:

(1) Sand making production and aggregate shaping in project fields such as hydroelectric, senior road, highway, high speed railway, passenger special line, bridge, airfield runway, municipal project and high-rise building.

(2) The forepart fine crushing craft of ore grinding in mine industries and material crushing in building material, metallurgy, chemical industry, mine, anti-fire material, cement and grinding material industries.

(3) Suitable for environment projects such as high abrasiveness and secondary breaking, thermal power, desulphuration in metallurgical industries, teel slags and construction wastes.Production for glass, quartz sand and other high purity materials.

Working Principle------sand maker:

Stone less than 50mm enters sand making machine though conveyor belt. Stone is crushed by hitting other stones. Material falls down to impellor cavity. Under great centrifugal force, it hits material that coming downwards. After hitting each other, they force a vortex between impellor and shell, and hit each other several times; finally smaller stone comes out, and goes to vibrating screen. Satisfactory material is transported to sand washing machine; however overlarge material will go back to sand maker to be recrushed. Output sizes can be made according to customers’ requirement. If input size is larger than the designed size, other crushing equipment will be necessary.
