BRIQUETTING MOBILE COMPLEX (MBP)
The plant is intended for getting fuel briquettes with binding additives and is used for:
- processing of fine coal processing waste;
- agglomeration of raw coal into suitable fuel, which contains basic coal filler of different quality with all the necessary features;
- ecological advancement in coal mining regions at the expense of processing coal wastes in the place of their dumping;
- coal strip mines and mines, traffic centers, transport nodal points, coal fuel depots, transfer platforms etc.
Traditional sources of raw material are used: peat, coal (coal cleaning wastes) of any kind (from anthracites, semi-anthracites and their wastes to gas coal and candle coal, as well as their slime and dry coal cleaning intermediate product).
Coal mixture with particles 0-6 mm in diameter is fed into the hopper of the plant. The moisture content of the mixture should be kept in the range of 6-12%. The inclusion of single granules (up to 10mm) is permitted, but their maximum amount should not exceed 5% of the total mass.
The compression strength of the briquettes is 3-6 MPa. In accordance with ГОСТ (State Standard) 21289-75, which determines the standard for impact resistance, after a briquette’s being released from a height of 2 m, the amount of fines should not exceed 15%. The density and mass of briquettes are always uniform.
The plant is mobile and integrated in a standard 12 feet container (6x2, 6x2.4 m), it has a compact design. It is supplied as a ready-to-use system and is installed without a foundation. The rollers are highly reliable as they are made of wear-resistant steel and are operated by a microprocessor. The equipment has both manual and automatic control. Information on current operating parameters is displayed on the monitor.
Diagram of briquetting plant in a container

The briquetting plant is installed in a container (11). Briquetting material (coal mixture with particle size bellow 6 mm and moisture content between 5 and 10 %) (1) is fed into the receiving hopper (3) by the belt feeder (2), dosed by the continuous batcher (6) and directed into the double-shaft mixer (7). At the same time, binder is fed by the dosing screw from the bin (4) into the mixer (7), there the mixture is homogenized to dryness, when necessary, water is added by the doser (5) into the middle part of the mixer. Then the mixture is compressed by the screw press (8) and fed into the roller press (9). The pressed briquettes are fed through the sieving machine by the belt feeder (10) to the take-away conveyer (12). Fines and spillage are collected in the box (14) and turned back for remoulding. The finished briquettes are dried in mesh containers and after achieving sufficient strength delivered to customers.
