1-13 Pneumatic Slide Gate Below Mixer (Optional)
The OS/OA blending system can be equipped with an optional pneumatic slide
gate below the mixing chamber. The gate is used in applications when the
blender is mounted above a large hopper, or for gaylord filling, etc. This gate
holds the material in the mixing section, to ensure that it is properly mixed.
Control of the mixer function is described below, and is determined by the
position of the “knife gate switch” located on the side of the back control panel.
