ЧеркассыЭлеваторМаш - Оборудование - Станок для получения топливных брикетов ЕВ-350

The following processes lie on the basis of this fuel briquettes producing technology:

Dosated feeding of the prepared raw material

Screw pressing of the raw material (SUNFLOWER AND BUCKWHEAT HUSKS, FLAX SHEAVE and well-milled waste products of hard and soft species of wood (WOOD CHIPPINGS) under high pressure within the extruder’s tool

Raw material brief heating by means of heating coils, installed on the operating element – from 250 to 350 С°.

raw material burning-out 2-4% with the smoke emission under the influence of high temperature

steam emission 2-3% (from the raw material mass)

smoke and steam outlet through the pilofacturing hole in the generated briquette

lignine emission (natural polymer) under the influence of high temperature and pressure

lignine fritting (fire polishing) leads to agglutination of the surface layer of FUEL BRIQUETTE

FUEL BRIQUETTE outlet from the operating element and it’s transference to briquette divisor

Receiving of the square FUEL BRIQUETTE with the length 150 (300) mm

FUEL BRIQUETTE cooling

			Received fuel briquettes do not include any binding materials, except one material – lignine, contained within the cells of vegetable material. Temperature during the pressing promotes fritting of the surface layer, which becomes more solid, which is very important for briquette transportation.

			Fuel briquettes production lines are completed in different ways, depending on the material used

			Production line of fuel briquettes from sunflower husks				Production line of fuel briquettes from wood chippings

Extruder for briquetting waste products EB 350 conforms to ТУ У 30842484.006-2004.

In-process waste products characteristics and extruder’s EB 350 capability for these kinds of waste products are given below:

*Characteristic/ kind of waste products*	*Wood chippings*	*Sunflower husks*
Density, %	to 8%	to 8%
Processing temperature, °С	320 – 350	250 - 290
Particle size, mm	to 10	2 – 8
Density, t/m³	0,2	0,12
Capability, kg/hour	350 – 500	300 - 350

SPECIAL ATTENTION!

RAW MATERIAL HUMIDITY – a very important characteristic, which affects upon the briquette’s density and marketable form and extruder’s capability. In case of exceeding the above mentioned demands, the briquette falls to voluntary pieces due to the excess of humidity, which comes out as a steam from the briquette. In that case it is necessary to dry out waste products before hand

One more problem – smoke utilization, which appears during the briquetting, must be solved by the consumer himself on the place of extruder’s operation.

The briquette, produced on extruder EB 350 is very close to coal by it’s physicochemical characteristics. Characteristics of received briquettes and coal for comparing are given below:

*Characteristic/ kind of* *waste products*	*Buckwheat husks*	*Sunflower husks*	*Wood chippings*	*Coal*
Density, t/m³	1,1-1,3	1,1-1,2	1,0-1,2	1,2 -1,5
Heating value, kkal/kg	4800 - 5000	5000 - 5200	4600 - 4900	4400 – 5400
Density, %	6-7	6-8	7-8	5-6
Ash content, %	0,5-1,6	2,7-4,5	0,5-1,5	14-19
Brimstone, %	-	0,23-0,45	-	5-15
