The castable refractory gunning machine is mainly used for spraying refractory, castable materials in steel plant. Compared with common dry mix shotcrete machine, lightweight insulating castable refractory gunning machine is also including high pressure water pump, new type pre-dampening nozzle assy, ABB frequency converter etc.
High pressure water pump is used for providing high pressure water for new type pre-dampening nozzle assy. There is one water ring in the nozzle assy, high pressure water goes through water ring small hole and atomize. If so, water could be mixed even with materials, achieve best spraying effect. ABB frequency converter is used for adjusting motor speed, further control refractory gunite machine output from 1m3/h to 3m3/h. When the machine begins to work, small output could effectively avoid block because of larger output.
  Nowadays, for castable refractory gunning machine, we have electric motor refractory gunning machine and full pneumatic refractory gunning machine. Whichever refractory gunning machine all need air compressor to provide compressed air.
Full pneumatic castable refractory gunning machine doesn’t need any electric power supply, suitable for using in remote working site. Most customers’ working voltage is different from ours, we could customize suitable voltage motor according to customers’ demands. We could provide LZ-3ER (3m3/h), LZ-3A (3m3/h) and LZ-5ER (5m3/h) for customer’s option.
For castable refractory gunning machine, sealing plate and steel rotor plate is key part, we provide nice quality sealing plate and steel rotor plate for our machine. Usually, sealing plate service life is about 300m3, steel rotor plate service life is about 20000m3.
Because of its high spraying construction speed, high efficiency, good quality and other significant advantages, castable refractory machine is widely used for industrial furnace refractory layer of thermal spray repair operations. The castable refractory gunning machine has the below obvious advantage:
1, The castable refractory gunning machine with mixing, transportation, spray function;
2, The better quality of insulation castable, construction speed, save labor;
3, Spraying metallurgy and industrial furnace, widely used in steel mills and so on;
4, The castable refractory gunning machine is the stereotypes of products, good quality, durable, wearing parts rotating plate, sealing plate, spray gun and other accessories have in stock. When using our lightweight insulating castable refractory gunning machine simply add water to the nozzle. Castable refractory gunning machine is equipped with a high pressure water pump for high pressure water and atomization in the nozzle. At the same time, the castable refractory gunning machine is also equipped with a new type of pre-damping nozzle assembly, which has lower rebound rate and less dust than other common nozzles, reducing the amount of water added. Equipped with ABB inverter, the output of the refractory glue machine can be adjusted according to the customer's project requirements.
LZ-3ER castable refractory gunning machine is specially designed for spraying refractory materials. The machine equipped with ABB variable frequency can achieve the variable output, which effectively avoided material clogging the pipeline phenomenon. Moreover, the machine is also equipped with collect dust bag, which can reduce greatly dust and protect the health of the operator.
