High efficiency sand making machine for sand making production line 

sand making machine features:

1. Large handling capacity and High output_50-500t/h, the output of VSI has been stably increased 30% comparing with the traditional equipment under the same motor power

2. Low wearing parts cost_Perfect impact angle design of the crushing cavity, less friction against the wearing parts. The operation cost reduces 40%. 

3. Perfect product shape _ Cubic products, suitable proportion and adjustable fineness modulus. It fits especially man-made sand and stone reshaping. The effect of making and reshaping sand has been increased 30% compared with the traditional equipment. 

4. Hydraulic devices are maintained easily_Hydraulic door-opened device make the repair in the crushing cavity easily. Shorten downtime and save effort. 

5. Automatic test, safe and reliable_Vibration display and warning device are set. The machine will be warned to stop working when abnormal phenomenon appears. 

6. Thinning oil lubricant and automatic maintenance_The original German thinning oil lubricant station, double-pump injection system guarantees the oil supply. The machine will stop automatically when there is no oil and pressure. Water cools the oil and electric motor is heated in winter. 

7. Easy installation and operation_Light weight, various forms of installation, movable installation. Easy installation, repair and maintenance. Once the specific use is cleared, VSI crusher can maximize its excellent performance by only minor adjustment. 

8. Multi-functions and Flexible application_Due to the unique feeding crushing structure and various kinds of crushing cavities. It is easy to change "rock-rock" to "rock-iron". So that it achieves the multi-use in one machine. If customers want to change the function of the machine, without making big adjustment, the machine can satisfy for customers' various need. Sand making, reshaping, abrasion, etc. 

9. International quality guarantee_The most advanced technology of Germany, and the internal and external quality has been greatly improved by advanced riveting technology. And appearance sand blasting, derusting and spray-paint technology of car. The core components are all international branded (adopting high precision grade TIMKEN rolling shaft). And make sure the lowest failure rate. 

10. New environment protection- Less noisy and pollution. It can be equipped with new dustproof devices, which benefit the environment

Working principle of the sand making machine : 

The entire center feeding: Material falls the feed hopper, then enters the high-speed rotary sling wheel from center feeding hole, which is speeded immediately in the sling wheel. The speed can reach several dozens times of the gravity acceleration. Then it is thrown from the sling wheel. First, it is crushed with other rebounded material fell freely from the sling wheel. Then both of them are impacted to the material lining (rock-rock) or strike back block (rock-iron), rebounded and stroke to the top of eddy cavity in the inclined-up direction. Then it moves along deflection-down, and forms a continuous material curtain with the material from the impellers passage. Just like this, the material is stroke, rubbed, crushed twice or more, then is discharged from the down discharging hole.
