Product Description

Zhengzhou Huaqiang Machinery Co., Ltd.

SPZ series concrete shotcrete machine is a kind of anchor shotcrete support equipment, which has the characteristics of reasonable structure, perfect performance and stable performance. Easy to use and maintain, durable. It is suitable for sprayed concrete construction of mines, tunnels, culverts, subways, slope support, underground engineering of hydropower projects and roadways of high gas mines.

Working principle of SPZ series concrete sprayer:

SPZ series concrete spraying machine is mainly composed of driving device, rotor assembly, air duct system, spraying system and electric control box. The mixed material is discharged from the mixer and enters the feed hopper of the spray vibrating screen. It is injected into the rotor body through the feeder and then to the outlet. Compressed air is introduced from the air chamber to blow the material into the discharge elbow. At the same time, another cyclone separator Introduce compressed air, the material is blown away and accelerated in the multi-head wind spiral state, and is output to the material pipeline to rotate and float, and then add an appropriate amount of water or liquid accelerator to spray out.

Features of dry spraying machine

1. Straight-through rotor, smooth discharge and high efficiency.
2. Four-point elastic compensation compression, good sealing effect, less dust, and reinforced wearing parts.
3. The low-pressure and high-speed eddy current airflow conveying overcomes the problems of viscosity, blockage and pulse dispersion in material conveying, and the material flows evenly, continuously and stably.
4. The new nozzle and outlet elbow device improve the spray effect, less rebound and high spray layer quality.
5. The sprayed chassis can be assembled into tire type, skid type and track wheel type with various gauges
