LZ-3ER/S Refractory gunning machine is specifically designed for refractory dry-mix shotcrete applications, as well as for concrete shotcrete application.
The output of LZ-3ER/S is 3m3/h, with an automatic cleaning system to clean delivery line blockage: PLC+VFD+Air Pressure Sensor and adding an automatic lubricator to the rubber seal plate to make the work life of wear parts longer and make the motor power lower, you can also get low dust and high performance spraying flow in the nozzle.
   
Compared with our market popular LZ-3ER Refractory gunning machine, this LZ-3ER/S is a new version.
 
Leadcrete refractory gunning machine is an ideal choice for blast furnace applications. Thanks to its high quality and outstanding features, it has received better feedback from customers. The refractory shotcrete machine is equipped with ABB frequency conversion, which can control the motor speed and realize variable output. This is very important to avoid clogging, especially when the refractory spray gun starts to spray refractory materials, if the output is too large, it is easy to cause clogging.

LZ-3ER/S Refractory gunning machine is also called refractory shotcrete machine or tank gunning machine. It is mainly used for repairing the lining of large converters, electric furnaces and blast furnaces in metallurgical enterprises. Use refractory spray materials to spray semi-dry spray paint on thermal equipment in steel plants. This refractory gunning machine has the advantages of reasonable structure, high efficiency and energy saving, uniform discharge, time-saving and labor-saving, and durability.

1. Automatically to clean delivery line blockage: PLC+VFD+Air Pressure Sensor.
2. The concrete pouring quality is good, the construction speed is fast, and the labor is saved.
3. The combination of refractory gunning machine and high pressure water, it is easy to move.
4. Gunning metallurgy and industrial furnaces are widely used in steel mills.
5. To add automatic lubricator to the rubber seal plate to make the work life of wear parts longer and make the motor power lower.
6. The refractory gunning machine has the functions of stirring, conveying and spraying.
7. Sector hole to replace the circle hole in the rotor to improve the volume of the rotor and to decrease friction area, then with the same output, the rotor speed will be lower to improve the work life of rubber sealing plate and keep the motor power lower. 
8. Refractory gunning machine is a stereotyped product with good quality and durability. The wearing parts, rotating plate, bonding plate, spray gun and other accessories are adequately stocked.
