C Series

Robust, compact, and low-maintenance

The C-Series machines are ideal for small and middle-sized operations whose average production volume averages 50-80 kg/hour, or about 200-400 kg/day. Briquetting can be practical for materials like wood, expanded polystyrene, styrofoam, paper, or biomass. All the machines in this line can be configured to discharge to the left or the right, depending on the needs of your operation. The assembly of the base frame makes installation quick and also makes it possible to install as a mobile machine.

Generous feed hopper as material buffer

C Series briquetting presses offer a large capacity for material to be compressed. Depending on the space requirements, the press unit and the hydraulic unit can be flexibly installed to the right or left of the hopper. The agitator and the material screw conveyor are located at the bottom of the hopper. If required, the hopper can be equipped with a fill level monitoring system which automatically switches off the briquette press as soon as the material quantity falls below a defined level.

Vertical material pre-compaction in the filling tower

The screw conveyor below the feed hopper transports a defined quantity of material into the filling tower. There, vertical pre-compaction takes place, with a slide pressing the material into the press sleeve below. A particularly solid briquette can then be produced after the subsequent clamp compaction.

Robust hydraulics with separate oil tank

The compact hydraulic unit is located directly next to the feed hopper. It is temperature controlled. The pump motor is designed for long service life.

Proven clamping technology for high-strength, round briquettes with 50 mm Ø

The extremely wear-resistant, chrome-plated pressing clamp is surrounded by a hydraulic closing cylinder. It holds the briquette produced by the pressing cylinder during pressing. For this purpose, both halves of the clamp are closed and opened again during discharge.

Uniform material transport into the screw channel

The agitator installed at the bottom of the feed hopper ensures a constant material feed to the screw conveyor. The continuous material circulation also prevents material bridging and breaks up lumps.

Simple machine operation with high-quality Siemens PLC control

No frills – the most important things at a glance. The built-in Siemens PLC control is optimally adapted to the briquetting process. Various settings can be conveniently adjusted to the desired application. All control cabinets are designed in-house and built in our German production facilities using international standard parts.

Consistent briquette lengths thanks to electromechanical monitoring

To ensure that the briquette length remains constant even with changing materials, briquetting presses of the C series come standard with an electromechanical briquette length monitor with proximity switch. This is located directly in front of the clamp on the briquette discharge pipe.

A true classic: the paper briquette

Filtered paper dust is turned into highly compressed briquettes with a diameter of 50 mm by means of a C 150 briquetting press.

Minimal wear in the press chamber due to pressing chamber wear sleeve

WEIMA’s standard pressing chamber wear sleeves are hardened. Optionally, they are made of tool steel. In both cases, increased wear of the press chamber is effectively prevented – especially with abrasive materials containing sand, soil, or metal chips. Instead of replacing the entire press block when wear occurs, only the significantly less expensive pressing chamber needs to be replaced. This saves labor, time, and costs – maintenance is significantly simplified.

Low maintenance hydraulic cylinder for optimized operations

All installed cylinders are have stroke cushioning and come equipped with a bolted lock. This guarantees easy access for maintenance or modifications.

Optimized material input by means of a screw conveyor

The material is conveyed in metered quantities from the hopper to the pressing unit by means of a screw conveyor. For this purpose, a precise quantity required to produce a single briquette is defined electromechanically via the screw speed and running time. Compared to conventional horizontal pushers, this efficiently avoids material bridging or clogging of the feed channel.
