1、 The working principle of the spiral dry powder mortar packing machine is that the packing machine needs screw to extrude materials when discharging, and the packing machine does not need compressed air when discharging. The advantages of this kind of packaging machine are less dust and high precision, but the disadvantages are also very prominent. It is troublesome to maintain and expensive, and the precision is slightly higher than the other two kinds of packaging machines. The error range generally does not exceed 0.6%.

2、 The working principle of the impeller type dry powder mortar packing machine is that the packing machine needs the combined action of compressed air and impeller when discharging. Due to its rapid discharge, easy maintenance and high cost performance, this packaging machine has become the mainstream of the market, accounting for more than 90% of the market share, but the dust is slightly higher than the other two packaging machines. The error range generally does not exceed 1%.

3、 The working principle of the air-blown dry powder mortar packaging machine is to use high-pressure air to blow directly when discharging. The packaging machine has a regulating valve, with adjustable pressure and precision, mainly for vulnerable particle mortar. The advantages of this packaging machine are high precision, good sealing, basically maintenance-free, less dust than the impeller packaging machine. The disadvantages are high equipment cost and slightly higher precision than the impeller packaging machine. The error range generally does not exceed 0.8%.
