We have refractory gunning machine for repairing furnace with various flow output, such as: 3m3/h, 5m3/h, 7m3/h, 9m3/h, and electric engine and air motor can be customized according to your requirements.
Refractory gunning machine for repairing furnace is mainly used for thermal gunning of the refractory layer of industrial furnaces. Widely used in tunnels, culverts, subways, hydropower projects, underground projects, mine roadways, highway slope protection and other concrete spraying, support construction.
Working principle of refractory gunning machine for repairing blast furnace:
Refractory gunning machine for repairing blast furnace uses compressed air to spray a certain proportion of refractory materials at a high speed to form a refractory layer on the surface of the sprayed masonry. It is widely used due to its remarkable advantages such as fast spraying construction speed, high efficiency and good engineering quality.
Spare parts of refractory gunning machine:
Refractory gunning machine for repairing blast furnace is specially designed for spraying refractory material. Refractory gunning machine for repairing blast furnace use priority spare parts and design, such as:
1. New pre-dampening nozzle
What’s the advantage of the new pre-dampening nozzle for the refractory shotcrete machine?
A. Low rebound, low dust.
B. Reduce additive water amount.
C. Improve refractory compactness and strength.
2. Special design: collect dust bag and clean dust gun
Besides, refractory gunning machine for repairing blast furnace wearing spare parts includes.
Rotor steel, upper and sealing plate, rubber chamber, cone casing pipe, rubber elbow, nozzle, conveying hose etc.
LZ-3ER refractory gunning machine for repairing furnace rated output is 3m3/h, its electric engine power is 4Kw, its operating air pressure is range from 2-4bar, its local voltage are respectively 3phase, 380V, 50Hz, and its max horizontal conveying distance is 100m.
LZ-3ER is an upgraded version of LZ-3ER refractory gunning machine for repairing blast furnace. Effectively reduces dust and greatly improves the spraying effect. Its rotor body hole and rigid liner are changed from round hole to fan-shaped hole, which increases the blanking volume and reduces the friction area. Thereby the service life of the LZ-3ER/S refractory gunning machine for repairing blast furnace is extended.
Its rated output is range from 1.5-3m3/h, its electric engine power is 4Kw, its operating air pressure is range from 2-4bar, its local voltage are respectively 3phase, 380V, 50Hz, and its max horizontal conveying distance is 200m.
LZ-3AR refractory gunite machine is driven by air motor. Its rated output is 1-3m3/h, its air motor power is 4Kw, its operating air pressure is range from 2-4bar.
