Dinamic 70S Series Briquette Machine
Hydraulic briquetting machine made in Italy for small businesses. It compresses wood chips and sawdust, paper, biomass, plastic, and other industrial materials into cylindrical briquettes with a diameter of 55 mm, reducing the volume of the chips by up to 90%. With an approximate production rate of up to 75 kg/h, it is the ideal solution for carpentry shops, artisan workshops, and small workshops.
From the hopper to the briquette: how the Dinamic 70S turns your waste into resources
A machine designed for those who produce few chips and want maximum efficiency
The Dinamic 70S Briquetting Machine is a Made in Italy hydraulic machine designed to transform wood shavings and dust generated by industrial processes into compact cylindrical briquettes, ready to be reused as fuel or sent to collection centers. It is the ideal choice for small businesses—carpentry shops, woodworking shops, and small workshops—that are looking for a reliable, compact, and easy-to-use solution for everyday operations.
New Technical Improvements Introduced in Version 2026: Why Quality Is Everything to Us
- New anti-return system
The new anti-return system for the lower spoke, unlike the previous one with rod and spring, features a body machined from solid and equipped with an adjustable ball bearing which eliminates wear caused by rubbing. - New magnets
The type of magnets present in the suction area of the hydraulic pump have been replaced with a neodymium model, the best currently on the market, up to nine times more efficient than the current one in order to make oil decontamination even more constant over time due to component wear and oil changes without proper cleaning. - New drawer cylinder stem
The new drawer cylinder stem has been completely redesigned, significantly improving its build quality by replacing the mechanical drawer opening stop, which was very noisy, with a rod limit switch and a solenoid valve for the drawer stop function. We have also optimized the ease of assembly, thus reducing the risk of damaging the seals during replacement. - New Pressure Switches and New Location
Compared to previous models, the new pressure switches are of significantly higher quality and perform much better, with an operating range that has expanded from 50–200 bar to 40 to 400 bar, with precise and simple vernier adjustment—a significant improvement over the previous, less intuitive, and cumbersome screw-type adjustment. Their location has also been changed; previously difficult to access, they are now positioned on the electrical panel bracket for much more practical and functional use. - New general pressure gauge
The new pressure gauge is used to monitor all the machine's operating pressures during the various work phases (clamp pressure - compaction pressure - general pressure). - Modified clamp opening valve
We changed the vice opening valve from normally closed to normally open to avoid residual pressure in the vice in the event of a power failure. - New power supply specifically for PLC
A new PLC-specific power supply has been inserted inside the electrical panel to adjust the input voltage and avoid any damage due to unregulated currents.
Key Standard Features
New pressure switches with an operating range of 40–400 bar, featuring a vernier adjustment knob located on the front of the electrical panel mounting bracket.
New general-purpose pressure gauge.
PLC with display.
Its compact dimensions—1,165 × 1,640 × 1,460 mm—and weight of 500 kg make it easy to install even in tight spaces without requiring dedicated infrastructure. The total installed power is 5.5 kW.
Compatible materials
Wood (all types), paper, cardboard, biomass, plastic, MDF, leather, and many other materials with moisture content between 8% and 17%. For non-standard materials, a free sample test is available at COMAFER’s R&D department.
Measurable operational benefits
Briquetting with the Dinamic 70S reduces waste volume by up to 90%, cuts recycling costs by 70%, and reduces handling and transportation costs by 80%. Briquettes made from natural materials also offer a heat output of 4,000–4,500 kcal/kg, which is 80% higher than that of conventional firewood: a tangible benefit for those who use briquettes as fuel for industrial boilers or fireplaces.
From hopper to briquette
How Metalpress series briquetting machines transform waste chips into resources in 4 stages.
01
Feeding
A hopper with motorized agitator ensures continuous feeding of metal chips
02
Dosing
A drawer operated by a hydraulic cylinder meters the material into the compaction chamber
03
Compaction
A compaction cylinder compresses the chips at pressures up to 3764 kg/cm2, separating the coolant during pressing
04
Ejection
A gate with specific anti-wear treatments, equipped with a hydraulic cylinder, ejects the finished briquette
Technical Features
Base frame with oil reservoir function
Designed and manufactured using high-quality, heavy-gauge sheet metal and tubular sections for excellent resistance to stress, in accordance with COMAFER technical specifications. It serves as both the main load-bearing structure and the oil reservoir.
Drawer hydraulic cylinder
Designed and manufactured with high-quality components that comply with COMAFER technical specifications. Its function is to operate the sliding drawer and dispense the material into the compaction chamber.
Compactor hydraulic cylinder
Designed and manufactured with high-quality components that comply with COMAFER’s technical specifications. Its function is to compress the material in the compaction chamber to form a briquette
Hydraulic system
Designed and manufactured with high-quality components that comply with COMAFER technical specifications. Its function is to manage the machine's operating cycle.
Pressure Gauges for Clamping, Compaction, and General Use
Accurate and reliable. Their function is to monitor the machine's various operating pressures.
Briquette ejection system
Designed and manufactured with high-quality components that comply with COMAFER technical specifications. It consists of a hydraulic vise mounted on a shaft with special anti-wear treatments, designed to hold the briquette during the compaction phase and control its movement and ejection.
Electrical panel with PLC and display
Designed and manufactured with high-quality components that comply with COMAFER technical specifications. It is responsible for the overall management and control of the machine.
