Product Overview

Creating mix products directly within the IBC is most suitable where the product must be handled gently with minimum damage or degradation.

Mixing directly within the IBC reduces the number of product transfer by Two (02) and a unique advantage of Cone Valve is that during each revolution, it separates and re-mixes the product, so creating a better quality mix.

Theory of Operation

BlenderThe Tumble Blender comprises a freestanding steel framed structure with a trunnion mounted rotating cage to hold the IBC. The IBC is loaded into the cage by forklift truck. As it is lowered down into the cage, the Cone Lock device at the bottom of the cage automatically locks the valve in place. The truck and operator exit the blender enclosure, lock the access gate, remove the interlock key and insert it in the control panel. The start button is pressed; the clamping system operates to clamp the IBC in the cage.

The cage then rotates at a predetermined speed and duration (optimum speed and blend duration and time found on commissioning). There are safety interlocks to stop the process if either the clamps slacken or valve clamp releases. The door is interlocked closed to prevent entry during operation.

The main drive motor is controlled by an inverter controller which starts and drops the process by gradually running up and down to full speed. This is a vital feature to minimise the torque and torsional stresses on shafts, cage and support structures. When the cage has slowed down at end of cycle, it is locked in the vertical position by a dynamic brake and then a pneumatic cylinder drives a locking bolt to secure the cage. The clamping system retracts to release the IBC and then release the door interlock to allow the operator to take the key from the panel, unlock the door and enter to remove the IBC.

Materials of Construction
  • Option A – All in mild steel rolled hollow sections, angle and plate painted etch primer, undercoat and full gloss to required colour.
  • Option B – Clamps in stainless steel grade 304 and cage clad in stainless steel sheet grade 304 brush finish.
  • Option C – Clamps in stainless steel grade 304, plinths and cage clad in stainless steel sheet grade 304 brush finish.
  • Option D – All in stainless steel sheet grade 304 brush finish.

Electrical wiring and pneumatic piping are terminated at a junction box and bulkhead connection respectively. The electrical connections should be made direct to the control panel which also requires a mains supply. An air supply should be taken direct to the blender.
