LZ-6AR/RD Pneumatic motor refractory gunning machine
LZ-6AR/RD Pneumatic motor refractory gunning machine is a small, economical, versatile, simple, and safe refractory gunning machine for refractory installation in steel plants, cement factories, furnaces, etc.
Product Details
Technical data
LZ-6AR/RD Gunning Machine is a refractory gunning machine with a maximum output of 6m3/h, driven by an air motor / pneumatic motor. It can provides a steady flow of material, which allows uniform hydration and very smooth spraying.

LZ-6AR/RD uses a pneumatic motor to rotate the machine's material feed bowl. An air compressor is required to convey material from the feed bowl to the nozzle (sold separately).

Working principle of LZ-6AR/RD Pneumatic motor refractory gunning machine:
① The dry material is sent down through the hopper into the pocket of the rotating feeding wheel below.
② The rotating feeding wheel is driven by heavy-duty oil bath gears, making the mixture rotate under the conveying air inlet and outlet.
③ With the introduction of compressed air, the mixture is discharged from the feed wheel pocket, and then enters the hose through the outlet.
④ Then the dry mixture is sent to the nozzle through the hose in the form of suspension, and water is added at the nozzle, and the water and the dry material are mixed.
