　　PS7IMining wet concrete spraying machineProduct Introduction

　　Wet spraying machine is a new type of concrete spraying machinery, mainly used for wet spraying of concrete. Wet spraying can make the mixture evenly mixed, accurately control the water cement ratio, and facilitate the hydration of water and cement. Therefore, it has small dust, small rebound, good homogeneity of concrete, and high strength. The machine has the characteristics of reasonable structure, stable performance, convenient operation and maintenance, and long service life. Widely used in the construction of sprayed concrete in mines, tunnels, culverts, subways, hydropower projects, underground engineering coal mine shafts and tunnels.

　　PS7IMining wet concrete spraying machineThe superiority of wet shotcrete technology is a new technology. Wet spraying has obvious advantages over dry (wet) spraying.

　　1. The mix proportion of wet sprayed concrete is easy to control during construction. The wet sprayed concrete is produced according to the production process and transported to the wet spraying machine for spraying. The mix proportion is completely controlled, thus ensuring the quality of the sprayed concrete. The quality of dry and wet sprayed concrete is difficult to control, especially the water cement ratio of concrete is arbitrary, which is adjusted by the shotcrete operator based on experience and visual observation. The quality of concrete largely depends on whether the shotcrete operator operates correctly or not.

　　two PS7IMining wet concrete spraying machineThe rebound rate is low, and the rebound rate of dry and wet spraying can reach 35% -45%, while the rebound rate of wet spraying is about 15%, so the production cost of wet spraying is low and the efficiency is high.

　　3. The dust concentration during construction is 60mg/m3 next to the low tide spray nozzle. The dust concentration next to the dry spray nozzle of PS7I wet spraying machine is higher than that of the wet spray powder, while the dust concentration next to the wet spray nozzle is lower than that of the wet spray nozzle. During the construction of shotcrete, low visibility in tunnels is often caused by dust concentration and other reasons, which objectively leads operators to only focus on the quantity of shotcrete and ignore the quality of shotcrete, resulting in unstable quality and significant waste.

　　four PS7IMining wet concrete spraying machineHigh productivity: Dry concrete sprayers generally do not exceed 5m3/h. When using a wet concrete sprayer, the manual operation can reach 7-9 m3/h, and when using a spraying robot, it can reach 15-18 m3/h, which is 2-3 times higher than other spraying methods.

　　5. The dry spray machine has a simple structure, small volume, and easy cleaning due to minimal material wear. However, the wet spray machine has a complex structure and large volume, requiring traction from larger power equipment. The wear of the bonding plate is minimal.
