This document is about “Choices”. Briquetting for any operation requires a biomass mold of one type or another, whether it’s a small village, single family, or classroom operation. You have “choices” and there are no wrong or right, best or worst, good or bad molds for making biomass briquettes.

A variety of molds will work equally well and one type may be best suited for you depending on the availability of construction materials, tools, cost, skill level, and briquetting requirements. This document provides choices to consider when selecting a biomass mold design.

Molds for shaping biomass into round, square, sticks, cubes & chunks. Drilled, slotted, and split PVC molds along with slotted wood as an alternate to PVC. Two caulking gun presses, split plunger pistons and more.

University of Nottingham uses the press and grinder for Kenya project; See http://www.nottingham.ac.uk/etc/news-SIFEKenya.php

The Easy BioGrind© biomass grinder was designed to grind dry biomass and to accomplish a number of goals. The objectives were the flexibility to grind a wide variety of dry biomasses, low-cost, easy to build using mostly hand tools, easy to operate, easy to maintain and require no welding.

The grinding process is accomplished by rotating a concrete grinding head with its aggregate exposed against a matching concrete grinding cup with its aggregate exposed, and introducing biomass in between the two surfaces. The grinding cup is supported with two degrees of freedom in order to absorb the movement from an out-of-round grinding head or the accidental introduction of small stones or stick into the grinding space. The grinding head is easily rotated using a hand crank at a slow speed (under 90 rpm). The unit can be powered from a bicycle, a foot powered treadle, a gasoline motor or an electric motor. Grinding pressure is easily adjusted by the weight of a few rocks in a pail.  See the Engineering For Change page E4C


Portable Thrasher, Masher Chopper

By the Legacy Foundation

I recommend you consider this new design by Richard Stanley from the Legacy Foundation. Preparing biomass for briquette production remains a crucial step in the briquetting process. Richard has developed (fine tuned and tested in rural Guatemala and Nicaragua over the past three years) a very successful idea as described in his new construction manual.

Designing a low cost grinder featuring ease of use, and easy to build, has been a challenge for both of us. We often work closely together in a effort to bring you the best ideas possible. You can contact Richard HERE

The Easy BioChop© biomass chopper / cutter was designed to cut both wet and dry biomass and to accomplish a number of goals. The objectives were low-cost, easy to build using mostly hand tools, easy to operate, easy to maintain and require no welding. The unit runs efficiently at a low crank speed and can be easily operated by women or children. See the Engineering For Change page E4C

LARGE COMPOUND LEVER PRESS FOR BIOMASS FUEL BRIQUETTES  Large Compound-Lever Biomass Briquette Press

Measured Drawing English Inches  340K PDF

This is the traditional large compound lever press used all over the world, and works with molds diameters from 3 inch to 6 inch.  Mold designs have greatly improved since the original design of this press and we suggest downloading:

Biomass Molds Compendium  See the compendium for a variety of biomass mold suggestions.

 

SMALL SINGLE LEVER PRESS FOR SQUARE BIOMASS FUEL BRIQUETTES Small Single Lever Biomass Briquette Press (Square Mold)

Measured Drawing English  570K PDF
If PVC is not available or expensive in your area then the 3 inch square wood mold could be an alternate.

 

Mold designs have greatly improved since the original design of this press and we suggest downloading: Biomass Molds Compendium for a variety of biomass mold suggestions. We now have a better method for making a square briquette using a wood mold.

 

SMALL SINGLE LEVER PRESS FOR ROUND BIOMASS FUEL BRIQUETTES Small Single-Lever Biomass Briquette Press
Suggested for use as a classroom demonstration briquetting  press or where construction resources are limited
