1.Introduction for dry sand making machine :
VSI series Sand making machine also called vertical shaft impact crusher, is a kind sand making equipment aims to produce artifical sand,VSI Sand Making Machine is of high efficiency and high performance crusher, low in maintenance and low operating cost. Our high proficiency sand making machine is designed and manufactured to produce fine quality sand with high productivity output. The final product is of cubical shape with grounded edges, which is widely used in concrete, building, construction.   Yufeng brand worldwide Complete dry sand making plant 

2.Working Principle of dry sand making machine:
1. Center Feeding:Raw material falls down into feed hopper, then enters impellor through central entrance hole. It is accelerated in high-speed impellor, then is thrown out at speed of 60-75m/s. When hitting impact plate, it is crushed. Final products come downwards though outlet.
2. Ring Feeding:Raw material falls down into feed hopper, then through ring, it is devided into two parts by material dividing plate. One enters into impellor through the center of material-dividing plate. The other falls down from outside of material-dividing plate. Material, which is thrown out by impellor at speed of 60-75m/s, hits material coming down from outside of material-dividing plate.  

3.Features of dry sand making machine:
1). Advanced doublepump oil lubrication system guarantee shaft bearing lower temperature increase, longer life time, more reliable operation. Dry Sand making plant 
2). Main shaft is equipped with imported precision rolling bearing. It makes main shaft work stable, lengthen maintenance cycle, increases productivity.
3). Hydraulic lifting mechanism of upper cover can move away the cover easily, which saves man power during maintenance.    Dry Sand making plant 
4). Overvibration device is equipped. There will be alarm when vibration surpasses a stipulated figure. It will stop the machine, in order to protect it. Dry Sand making plant      

4.Advantages of dry sand making machine (vertical shaft impact crusher):
1). Competitive capital cost, especially when compared with conventional crushing equipment.
2). Low service and maintenance requirements along with minimum operating and wear costs.
3). Rock-on-rock technology minimizes wear part requirements.
4). The vertical shaft impact crusher is Quick and easy installation. Crushers require minimum support structure and are also ideal as portables.
5). Ability to control product grading, maximizing or minimizing fines production.
6). The vertical shaft impact crusher produces a product of superior cubical shape.
7). More tolerant than conventional crushers to difficult feed conditions.
8). Quick balance rotor which is easy to use and service.
9). Simple, reliable grease lubrication.    Dry Sand making plant 
10). The vertical shaft impact crushers have Range of models available to suit any capacity. 

5. Why should you choose Yufeng dry Sand Making Machine?

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 consumption—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. Dry Sand making plant
