Introduction Of Concrete Spraying Machine
Concrete spraying machine is a wet shotcrete equipment, compared with dry and wet spraying machine,have the advantages of little working dust, small rebound spray , protect the environment, save raw materials and improve the quality of shotcrete and other significant advantages, like, operation and maintenance convenient. Using the working principle of low-voltage low-speed vortex conveying,close to jet,which overcome the plugging pulse, segregation problems. Made the injection material flow uniform and stable to improve spray layer material.
Feature Concrete Spraying Machine
Using wet spraying machine can greatly reduces the dust concentration and spring rate, increases the thickness of a spray, improves production efficiency, and ensure project quality.
Advantages:
①sealing structure is good, reduce dust pollution and small dust .
②small rebound and saving material.
③as the concrete mixed well prior to grouting, so ensure the ratio of concrete and the quality.
Disadvantages:
①high price of piston wet spraying machine;
②the transport of wet concrete is too much trouble, and sometimes needs concrete tank and other equipment;
③after each injection operation, the machine must be cleaned with water.
