Loading

The Mk 8 Rollo-Mixer is designed to receive material by gravity at the 12:00 position, shown above. Bag & barrel stations are used to charge the mixer, and can be fed through de-lumpers. The innovative retractable seal design, allows for a safe, smart, dust-free load in cycle.

Discharge

After uniformity is achieved, the dry powder mixer is ready to discharge the batch in the 6:00 o’clock position. A programmable butterfly valve is adjustable from 0–100% open, giving full control of product flow. The retractable bladder seals against any barrel, tote or super sak. As batch is discharged, we allow ventilation for the tote by displacing the air to a dust collector or plant wide system. This provides a dust-free batch cycle on the dry powder blending. Large Mk VIII Rollo-Mixers can discharge 2,000 lbs in 8 seconds. Discharge is 100%.
