The mortar spraying machine adopts trapezoidal grinding roller and grinding ring which can improve the crushing efficiency. The mortar spraying machine designs the grinding roll and ring into a stepped shape, which reduces the sliding speed of materials between the grinding roll and ring. Thus, the rolling time of materials is prolonged and the crushing effect is improved.
The utility model relates to a pressurizing spring which can balance the pressurization effect and an elastic connection which can smooth the shock absorption effect. The mortar spraying machine adopts the lever principle to connect the symmetrical grinding roller assembly with a horizontally placed spring through a pull rod. When a grinding roller assembly is placed on top of a large material, its radial force can be balanced by transmitting it to the grinding roller assembly on the symmetrical surface through the spring pull rod. Under this condition, the overall stress point of the device is increased by about 40% compared with other products. The elastic coupling device reduces vibration and noise and avoids resonance.
Equipped with powder separator impeller which can improve powder separation accuracy and high product density. The practice shows that increasing the blade density can improve the fineness of the finished product under the condition of constant rotating speed. In other words, when the fineness of the finished product does not need to be changed. The high-density impeller can rotate at a lower speed than the low-density impeller, reducing the air flow resistance. Under the same driving force, the output of finished products is increased by 50%.
