Designed and engineered to meet the most demanding recycling situations, our recycling Trommels offer robust and reliable separation of fines from a variety of waste streams.

Built with minimal maintenance in mind, ProStar Trommels offer efficient and flexible screening that you can rely on, incorporating a Heavy Duty Quad Drive arrangement, and built to suit your exact requirements.

Mounted on heavy duty support frames, our Trommel Screens can be specified as mobile or built onto bay-wall sections to be used as a static unit within a line. When screening materials with high moisture content, the Trommel can be fitted with a drum cleaning brush to ensure optimum efficiency.

Fitted with Inverter Variable Speed, our advanced Trommels are energy efficient and can be fully controlled to match the throughput of your process.

We produce a comprehensive range of standard build screens and materials handling equipment, which can be supplemented by specially designed bespoke equipment, purpose built to customer requirements.

The VariStar 34M is a semi-mobile Star Screen which incorporates a VariStar 12-1200 Adjustable Star Screen on a wheeled chassis for mobility around the yard.

The VariStar 34M gives you the flexibility of an adjustable Star Screen within a compact mobile package. The machine features a variable speed Feed Hopper, Star Screen, Oversize Material discharge belt and a foldable side elevator for discharging fines material.

The Star Screen unit is full adjustable between 10-50mm at the touch of a button, the same as it’s static cousins. The Robust Chassis is fitted with a conventional drawbar at one end to allow the operator to easily move the machine around the yard.

Varistar 34M machines are available in two standard sizes:-

Originally designed and patented by ProStar, the VariStar is the Star Screen which features shafts that are adjustable for gap, this gives the operator the facility to screen different materials at different sizes, and to fine-tune the screening size instantly, at the touch of a button.

The adjustable-shaft design allows for a screening range of 10-50mm on a standard layout. Shaft speeds are governed by inverters giving control over throughput.

Each shaft is driven by its own motor, thus there are no chains & sprockets to maintain. Also, if a motor were to fail then only one shaft would stop rotating and the machine could still be used until the motor is replaced/repaired.

Input materials are generally pre-screened, crushed or shredded. The VariStar can accept input material up to a 300mm cube, depending on bulk density.

Varistar machines are available in two standard lengths and three standard widths:-

3.4m 12 shafts x 1200 wide – 1560mm wide – 2000mm wide
5.0m 18 shafts x 1200 wide – 1560mm wide – 2000mm wide
Bespoke sizes are available on request.
