Mortar sprayers are currently mainly divided into screw type, plunger type and hose peristalsis type.

Although the screw type can be sprayed with high viscosity evenly without pulse, it has very strict requirements on the mortar and cannot have large particles. The screw pusher and the stator and rotor wear out relatively quickly. The imported ones are used for half a month at most, and the cost of replacing them is tens of thousands of yuan.

The advantage of the plunger type is that it is relatively fast, and it is suitable for the spraying of ordinary mortar with a low proportion of sand.

The proportion of sand should not be too large, and the particles of sand cannot be sprayed on materials with high viscosity.

Hose peristaltic mortar spraying machine, which sprays mortar with large flow rate, high pressure, and multi-purpose machine. It combines the advantages of the first two machines and is suitable for various types of mortar, especially with high sand mixing ratio and high viscosity. It is suitable for various construction conditions, easy to operate and maintain, and can be operated skillfully without special training.
