Horizontal Mechanical Dryers - Plastic

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. To ensure our dryers are simple to maintain, the rotor is fitted with easy-to-change wear paddles coated with our specially developed anti-wear coating, known as ‘blue lining’.

The wet plastics are fed into the Rotajet mechanical dryer where the plastic particles or flakes are impacted by the 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 spray bars outside the screen. The unwanted materials are then removed from the dryer by a screw conveyor. These additions to a standard mechanical dryer system radically decrease processing downtime and thereby drastically increase your overall throughput rate. 

As water and contamination is forced outside the perforated screen, the material builds up at the base of the machine. This waste material is then removed automatically by either a air blower or screw conveyor, depending on your requirements.

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.

Features & Benefits

Rotajet horizontal dryers are intelligently designed to keep processing downtime to a minimum. Spray bars and pneumatic screen scrapers are fitted to remove unwanted materials quickly and easily.

All of our drying systems have been designed to make your installation process as simple as possible; making it easy to add a Rotajet mechanical dryer into any production line.

Using kinetic energy, centrifugal force and air pressure to drive the material through the machine generates a throughput rate that is unbeatable by standard mechanical dryers.

Thanks to the design of our mechanical dryers, moisture from the input materials are quickly reduced to less than 1%.
