Overview------PLF sand making machine

• PLF sand making machine (Vertical shaft impact crusher) is researched by our company based on the internationaladvanced technology through optimized design
• It has the characteristics 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 madesand
• so it is widely used in hydroelectric project ,roads ,building construction, cement and metal mining industries for fine crushing .
• 

Advantages------PLF sand making machine

• 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 30% lower than the traditional equipment. It can directly decrease the equipment operation cost .

• 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.
• Easy maintance: 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.
• Easy installation and operation: 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.

Usage------Sand making machine

• 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.
• 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.
• 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 making machine

• 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 goeso 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 madeaccording to customers’ requirement. If input size is larger than the designed size, other crushing equipment will be necessary.
