LZ-1.5ER Refractory dry gunning machine for refractory installation is specially designed for spraying refractory materials, as well as for concrete shotcrete application. 

dry mix refractory gunning machine


Compared with ordinary dry-mix shotcrete machine, it has outstanding features such as low rebound, low dust, reduced water addition, and improved refractory compactness and strength, which can effectively reduce refractory waste. This is very important to the end user, as we all know that the price of refractory castables is higher than that of ordinary concrete, and saving refractory castables means saving production costs.


Leadcrete Equipment as a castable refractory gunning machine supplier and manufacturer has developed seven different output refractory dry gunning machines, include LZ-1.5ER, LZ-3ER, LZ-3ER/S, LZ-5ER, LZ-9ER, LZ-3AR, LZ-5AR.

Every model refractory dry gunning machine  has been equipped with an ABB frequency converter, a high-pressure water pump, and a new type of pre-dampenning nozzle.

ABB frequency converter could adjust the motor speed and control the output, on the other hand, could avoid clogging the hose due to excessive output when starting.

A high-pressure water pump could provide high-pressure water for gunning machine, then go through the water ring hole atomization, which could make water and refractory castable materials fully mixed with refractory pre-wet.

In a new type of pre-dampening nozzle, there is two needle valve to control two water line. The operator could adjust the needle valve to precise control of water amount, if so, greatly reduces operator proficiency requirements. 
With this LZ-1.5ER, you can get low dust and high performance spraying flow in nozzle.

1. Low rebound, low dust;


2. Reduce additive water amount;

3. Improve refractory compactness and strength. 



LZ-1.5ER Refractory dry gunning machine for refractory installation can be used for the maintenance and repair of refractory linings, as well as for the installation of refractory materials in the following fields of application: steel industry, iron industry, power generation industry, ceramic industry, cement industry, metal, and mining industry.

We have exported our r
efractory dry gunning machine to India, Indonesia, Malaysia, Thailand, Vietnam, Egypt, Saudi Arabia, South Africa, Pakistan, etc, receiving better feedback from our customers.

Now we could provide electric motor and air motor refractory gunning machine for customers option. For some working site is remote, inconvenient to get electric power, air motor drive refractory gunite machine will be a good choice for customers.

Electric power refractory gunite machine: LZ-1.5ER, LZ-3ER, LZ-3ER/S, LZ-5ER, LZ-9ER

Air motor drive refractory gunite machine: LZ-3AR, LZ-5AR

We have updated our refractory gunning machine after customer feedback, single hopper refractory gunning machine could effectively reduce material leakage in the use. An electric vibrate motor has much more exciting force than an air vibrating motor.
