PLF sand making machine (Vertical shaft impact crusher) is researched by our company based on the international advanced technology and through optimized design .It has lower price and lower energy cost .It has the characterics of working reliable and stable ,easy maintenance ,high working efficiency and wide application .The particle shape is cubic and needle flake content  is low ,so it is especially suitable for stone plastic ,machine made sand ,it is widely used in hydroelectric project ,roads ,building construction , cement and metal mining industries for fine crushing .

First .The reason of 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 .The material crack along their natural texture face and cleavage face to make the good particle shape and low consumption .This machine  can realize the switch the two working principle of “stone hit stone ”and “stone hit iron ”.

2 The Low consumption of quick –wear part

The best design of crushing cavity angle for the material to impact , little fraction with the quick-wear part ,and the operation cost is *0% 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.

Second .The reason of maintenance easy

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.

Third .Installation and operation easy

The equipment is light and the installation is diversiform, it can use mobile installation ;Install ,repair and maintenance is simple ,the operation is convenient to use ;once the uses is specific ,the machine can maximize its outstanding performance after subtle adjustment.
