The mortar spraying machine adopts trapezoidal grinding roller and grinding ring which can improve the crushing efficiency. The machine designs the grinding roll and grinding ring into a ladder shape, which reduces the sliding speed of materials entering between the grinding roll and the grinding ring. Thus, the rolling time of materials is prolonged and the crushing effect is improved.
The compression spring that can play a role in balancing the pressurization and the elastic connection that can play a role in stabilizing the shock absorption. The machine adopts the lever principle to connect the symmetrical grinding roll assembly with the horizontally placed spring through the pull rod. When a grinding roll assembly is placed on top of a large material, its radial force can be balanced by transferring it to the grinding roll assembly of 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.
It is equipped with a separator impeller that can improve the powder separation accuracy and product density. The practice shows that the fineness of finished products can be improved by increasing the blade density under the condition of constant rotating speed. In other words, 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 airflow resistance. Under the same driving force, the output of finished products will increase by 50%.
