Micro Compound Lever Briquette Press

Both versions, Brace and Notch designs, have a total of 10 parts (two front and two rear leg, two feet, two arms and a level arm, two base beam, a handle, two beam sides and a brace) mainly made by same section pieces of wood (38 x 89 mm) and with different lengths. Pieces are joined with bolts and nuts, resulting in a lightweight press structure of 12 kgs. Softwood can be used and hardwood is recommended for the high-pressure level arm.

Full instructions and photographs on how to build the press are given in the construction manual. For further details contact the designers.

With 32 kg of force on the handle, 1,800 kg of force is transmitted to the briquette located 100 mm from the end pivot point. Based on a typical biomass pressing requirement of 65 kg/in² of force, the required pressures are 400 kg for a 75 mm briquette with a 25 mm hole, 1,040 kg for a 100 mm square briquette with no hole, 1,800 kg for a 150 mm diameter briquette without the hole. The press can easily exceed those force requirements.

Potential hazards include cuts and accidents when cutting the wood pieces for the structure. During periods of non-use, EWB recommends storing the product in a dry and sun free location.
