Rotajet mechanical dryers vertical
Rotajet manufacture the MDV series of vertical mechanical dryers, this type of dryer is the most efficient way of dewatering granulated plastics and pellets down to moisture levels around 1% (for rigid`s.) The machine is fitted with a Rotor which rotates at high speed (1350rpm typically).
The wet plastics are fed into the Rotajet MDV dryer using a screw conveyor, once in the dryer , the plastic granulate or pellets are impacted by the rotating rotor. The impact from the Rotor paddles, drive the plastic particles to the outside of the dryer using centrifuge force, the moisture is removed from the surface of the plastic particles and is driven through the “easy to change” dewatering fixed screens. The dried plastic is transferred up the dryer with by further impacts from the paddles and air flow created by the high speed paddle.
The Rotajet mechanical dryers are fitted with cleaning outside spray bars, and a keep the screens free of paper pulp, dust, dirt etc…
The dust and dirt are removed from the dryer using either a screw auger conveyor or a stator pump.
After the Rotajet mechanical dryer, the resulting dried plastic is normally either sent for bagging off, or for further processing through a Rotajet Zig Zag separator.
