Advantages of Germany technology VSI limestone sand making machinery
1.The sand making machine has a simple structure,unique bearing and advanced spindle design,which makes the sand making machine have the characteristics of heavy load and high speed rotation;
2.The sand making machine has a good shaping function for the ore, and the finished material has a more uniform particle size;
3.With fine crushing, rough grinding function,high efficiency and energy saving,high wear resistance,long service life of wearing parts;
4.During the production process,the stone material can form a protective bottom layer,and the body is wear-free and durable.
Through systematic mechanical analysis and verification, we optimized the structures of impeller and quick-wear parts, which greatly reduces the material passing resistance. Compared with the traditional impact crusher, this design obviously increases the material throughput and ratio of crushing, and enhances the working efficiency by 30%-60%; the realignment and modular design of the quick-wear parts in the impeller guarantee the repeated utilization factor of quick-wear parts and reduce the wear cost by more than 40%.
In consideration of the maintenance and part replacement problems during the production process of the sand maker, we abandoned the traditional laggard cover opening modes of hoisting and manual jack, and introduced semi-automatic hydraulic system; the operator only needs to press the button to open the top cover of the machine, and carry out the following operations. This system greatly reduces the manual labor intensity, which saves the labor cost and enhances the service efficiency.
Working principle-Germany technology VSI limestone sand making machinery
1.Central feeding:Raw materials fall down into the feeding hopper of the VSI sand making machine,then enters the impeller through central entrance inlet,thus the material being accelerated by the high-speed impeller and being thrown out at the speed of 60-75m/s.It is crushed when hitting the impact plate,and the end products comes out from the discharging outlet.
2.Ring feeding:Raw materials fall down into the feeding hopper,and the materials are divided into two parts by a special plate.Some materials enter the sand making machine’s impeller through the center of the plate and the other part of materials falls down from outside of the plate.The materials thrown out earlier crush the materials down from outside,thus the materials crushed and re-crushed.
