LZ-9ER Electric motor castable refractory gunning machine is not your typical dry mix gunning machine. It's specially designed for the precise application of refractory materials and castable substances.

straight chamber rotor type refractory gunning machine

This refractory dry mix 
castable gunning machine is equipped with an ABB frequency inverter, allowing for an adjustable output ranging from 3m3/h to 9m3/h.

Refractory Castable Insulating Gunning Machine

Refractory Installation Equipment

In comparison to conventional dry mix shotcrete machines, the castable refractory gunning machine is equipped with a new type of pre-dampening nozzle assembly. This innovative system acts like a pre-wet system, where a high-pressure water pump delivers water to the nozzle water ring, effectively mixing water with the refractory materials. This process significantly reduces the rebound rate.

High alumina castable refractory gunning machine

Typically, a common concrete dry mix shotcrete machine has a rebound rate of around 20% to 30%. In contrast, the rebound rate for the electric motor castable refractory gunning machine in China is impressively low, at only 10% to 15%. This reduction in rebound is especially cost-effective because refractory materials are more expensive than standard concrete.

Moreover, using this refractory gunning machine results in minimal dust at the work site, which is not only beneficial for the equipment operator but also helps to maintain a healthier work environment.

LZ-9ER Electric motor castable refractory gunning machine is a well-proven procedure by which refractory material and castable can be applied quickly and cheaply. It is used for the hot repair of ladles and melting furnaces as well as relining or cold repair of the back lining.
