      New type numerical control impact sand making machine :
        In view of  requirements for making sands from  large amount of pisolite with a size range of 5- 15 mm at the quarries , an impact sand making machine has  been  developed by our company . When the machine is working, the rotor driven by the electromotor rotates at a high speed, and the  stones enter  the functioning area of   blow bars  and impact the blow bars mounted on the rotor  and are crushed , and  then thrown onto the impact liners to be crushed again by impact,  and rebounded into the functioning area of  blow bars to be crushed  once more by impact. Such a  process will be repeated for stones to enter the 1st, 2nd and 3rd crushing cavity based on the size range from big to small until the crushed stones are  small enough to escape from the bottom discharging port .  It is possible to change the discharge sizes by adjusting the space between the impact rack and the rotor , or by adjusting the rotating speed of the rotor .
        The crushed sand product produced by the machine is of a similarly cubic shape  , free of tension and free of fissures, meeting the requirement of high quality stipulated by expressway , high-speed  rail and cement mixing station  and so on .
        On the basis of the impact sand making machine,  our company has optimized the technical parameters for the new type impact sand making machine . As dovetail slots on the blow bars and dovetail keys on the blow bar seats  form clamping  match , blow bars on the rotor   are assembled with key-slot clamping plus bolt fastening , ensuring no falling off of blow bars and ensuring safety of the whole machine during operation .The impact angles are designed scientifically to increase the impact force . Repeated impact between stones and blow bars , between stones and impact  liners ,and rock-on-rock will occur for many times when the stones move down in the crushing cavity, leading to higher crushing rate and higher output of sand product   and lower abrasion cost .  High efficient blow bars  are adopted . High efficient blow bars  are cast precisely with high chromium alloy of special prescription for improving the abrasion resistance . Blow bars are thickened and widened for improving grinding  quantity and  utilization  rate  of  blow bars. The structure of the machine is improved, adding  side doors  and a back window for convenient replacing of blow bars and impact liners , and for convenient checking and maintenance  inside the machine  chamber. An equilibrium feeder is configured,  allowing  stones to distribute uniformly in the crushing cavity and improving the utilization of  impacting space inside the crushing cavity, and hence improving crushing rate  and output of  finished sand products .
        On the basis of the new type impact sand making machine, a variable frequency controller has been configured for the new type numerical control impact sand making machine . Variable frequency technology is used to adjust  the rotating speed of the rotor and regulate automatically  the discharge sizes of products ,  and improve sand product yield rate and output of finished products.  National patent has been applied for the new type numerical control impact sand making machine .
