Rotajet - Horizontal Mechanical Plastic Dryers

Rotajet manufacture the MD series of horizontal mechanical dryers, this type of dryer is the most efficient way of dewatering granulated and shredded plastics. Our mechanical dryers can reduce moisture levels for rigid plastics down to around 1%. The machine is fitted with a Rotor which rotates at high speed (approx. 1450rpm). To ensure our dryers are simple to maintain, the rotor is fitted with easy to change wear paddles manufactured from D2 steel.

The wet plastics are fed into the Rotajet mechanical dryer where the plastic particles or flakes are impacted by the rotating rotor. The impact from the Rotor paddles creates centrifugal force to drive the plastic particles to the outside of the dryer. The moisture is removed from the surface of the plastic particles and is driven through the dewatering fixed screens. The impact of the high-speed paddle also forces the dried material through the machine to the output mouth.

During the drying process contaminants such as paper pulp, dust and dirt build up against the screen. To combat this, our mechanical dryers are fitted with outside spray bars and a pneumatic screen scraper. The unwanted materials are then removed from the dryer by either a screw auger conveyor or a stator pump, depending on your application. These additions to a standard mechanical dryer system radically decrease processing downtime and thereby drastically increase your overall throughput rate. 

After the material has been processed by the Rotajet mechanical dryer, the resulting dried plastic is normally sent for bagging off or for further processing through a Rotajet Zigzag separator.
