Apparatus for communition of organic matters

An apparatus for comminution of organic material, such as synthetics, wood, agricultural wastes, and rubber, comprising:

• (a) a comminution unit having a tool provided with a cylindrical pressure chamber to receive said organic materials to be crushed and with a driven stamp axially displaceable and arranged to move within said chamber, said chamber being provided with a plurality of yielding openings;
• (b) an intermediate-pressure compacting unit positioned at the input to said comminuting unit and configured to compact said material as it advances in the direction of the movement of the organic matter to be comminuted, said compacting unit and being formed as a bell-mouthed narrowing chamber;
• (c) a feeding-precompacting unit positioned to feed said compacting unit and comprising a driven worm;
• said worm of the feeding precompacting unit, and said bell-mouthed narrowing chamber of the compacting unit being coaxially arranged and said driven stamp being guided in a tubular shaft of the worm and through said bell-mouthed narrowing chamber.

Apparatus for comminuting material, comprising;

• (a) a comminuting die defining a pressure chamber for receiving organic material to be crushed and further defining a plurality of small output openings and further defining an input port;
• (b) a driven stamp configured and dimensioned to pass through said input port, and slidingly and matingly engage said chamber for movement into and out of said chamber;
• (c) a compacting unit having an output coupled to said port of said die and having an input, said compacting unit defining a funnel-shape narrowing chamber, said chamber having a wide end and a narrow end, said narrow end comprising the output of said compacting unit and said wide end comprising an input of said unit;
• and
• (d) a feeder pre-compacter comprising a driven worm for receiving organic material and advancing said organic material into said compacting unit, said driven worm defining a passage for receiving said driven stamp, whereby said driven stamp may be driven through said given worm, said compacting unit and said die.
