■ Description

GZ-6AR/RD Air Driven Refractory Gunning Machine provides a steady flow of material, which allows uniform hydration and very smooth spraying.

$air driven refractory gunning machine structure$

The adjustable output of the material may be increased without sacrificing the quality of the application. The compact GZ-6AR/RD is capable of spraying through 38mm inner diameter conveying hoses.

GZ-6AR/RD uses an air 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).

Operating Principle of GZ-6AR/RD Air Driven / Pneumatic Motor Refractory Gunning Machine:

$Operating Principle of Refractory Gunning Machine$

① The dry material is fed through the hopper down into the pockets of the rotary feed wheel below.

② The rotary feed wheel, driven by a heavy-duty oil bath gear drive, rotates the mix under the conveying air inlet and material outlet.

③ With the introduction of compressed air, the mix is evacuated from the feed wheel pockets, then travels through the outlet and into the hoses.

④ The dry mix material is then conveyed in suspension through hoses to the nozzle, where water is added, and the water and dry material mix.

■ Application

GZ-6AR/RD Air Motor Refractory Gunning Machine is widely used in refractory spraying and installing projects in in steel mills, cement plants, glass factories, industrial furnaces etc.
