Working Principle

VSI sand maker adopts the principle of advanced selective crushing and cleavage crushing which directly exerts kinetic energy on materials and transforms the energy into crushing energy through impact. Materials break along with natural texture and cleavage surface. The products are in good shape and the energy consumption of the machine is low. It can achieve the transformation between two working principles of “stones break stones” and “stones beat the iron”.

Center Feeding:

After entering the feeding hopper, materials go into the speedy swing wheel through central feeding pore and are accelerated inside it with the acceleration in dozens of times the speed of gravitational acceleration. Then, they will be thrown from the swing wheel. Firstly, they impact with the other part of materials which fall free after rebounding. Then, they will crash onto the underlayer of materials (stones break stones) or impact block (stones beat iron) together and rebound obliquely to the top of the vortex cavity. With the direction of movement changed, they will move downward and impact with materials emitted from the runner of the impeller which forms continuous material curtain. Thus, the materials are impacted, abraded, ground and crushed for twice or more times in the vortex crushing chamber and will be discharged from the lower discharging outlet .

Performance Characteristics

1.Big volume, high output--50-500t/h, compared with other traditional machines under the same power, the output increases stably by 30%.

2.Low consumption of abrasive components—the best designed angle of the impact of materials in the crushing chamber and less friction of wear-resistant components; the operation charges decrease by 30% compared with other traditional machines which directly reduces the cost for use.

3.Good shape of products—cubic products, good shape, reasonable gradation, adjustable fineness module, especially applicable in artificial sand making and stones shaping; it’s proved that the shaping effect increases by 30% compared with other traditional sand makers.

4.Hydraulic device, easy maintenance—hydraulic opening device makes it easy and convenient for the repair and replacement of components in the crushing chamber which reduces the shutdown time.

5.Automatic detection, safe and reliable—vibration meter and the alarm will send off signals to stop it and protect the machine if it breaks down.

6.Thin oil lubrication, automatic maintenance—the original lubricating station in German, the oil pumps complement each other to ensure the oil provision. It will stop automatically when there is no oil flow and oil pressure. Oil cooling and heating device ensure the bearing lubrication to be in the best state, which thoroughly solves problems like heating of bearing, keeps the main bearing at a constant temperature and prolongs the period of maintenance and life of use.

7.Easy installation and operation—lightness, various ways of installation, movable installation; easy installation and maintenance, convenient operation; once the specific use is cleared, VSI sand maker can furthest bring its outstanding performance to full play just by some adjustments.

8.Versatile and flexible—unique structure with various types of crushing chamber makes it possible to achieve the transformation between “stones break stones” and “stones beat iron”. Thus, it’s easy to be versatile for the machine. There is no need for many adjustments to change the application of VSI crusher. It can satisfy different requirements of clients: artificial sand making, stones shaping, materials grinding, etc.

9. International quality assurance—the latest technology and craftwork from German, the advanced welding technology and the application of outer sand blast derusting and spray paint of automobile technology greatly improve the inner and outer quality of the application. The core spare parts are all from well-known international brand (the bearing adopts TIMKEN antifriction bearing of high accuracy), to guarantee the low ratio of system breakdown.

10. Environmental-friendly—low noise, no pollution. Unique air flow self-cycle system greatly reduces the exhaust volume and the dust beneficial to the environmental protection. Besides, VSI sand maker has room for other kinds of dust catchers.
