Wode Equipment as refractory gunning machine for sale supplier has developed two different output castable gunning machine, WZ-3ER (3m3/h) and WZ-5ER (5m3/h). Every model refractory gunning machine, all been equipped with an ABB frequency converter, high-pressure water pump, and new type pre-dampening nozzle. ABB frequence 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. High pressure water pump could provide high pressure water for gunning machine, when going through the water ring hole atomization, could make water and refractory castable materials fully mixed with refractory pre-wet. In the new type pre-dampening nozzle, there are two needle valves to control two water lines. The operator could adjust the needle valve to precise control of water amount, if so, greatly reduces operator proficiency requirements.
