Line for briquette production LDB-350 DUO with dryer SA-800 | 66 kW
- Product Code: LDB-350Duo+SA-800
Description
LDB-350 DUO Line with SA-800 dryer is a solution that enables the conversion of biomass (sawdust, straw, leaves, paper waste, and other residues) with moisture up to 60% into compact and compressed Nestro-type fuel briquettes. It performs perfectly in households, greenhouses, and companies, offering a range of benefits:
- versatility – processes a wide range of raw materials such as sawdust, straw, leaves, paper waste, and other residues;
- SA-800 dryer – ensures optimal drying of biomass, allowing the use of raw material with moisture up to 60%;
- flexibility – the double screw in the feeder and inverters provide independent control and adjustment to changing production needs;
- interchangeable forming sleeves – allow for the regulation of diameter and degree of compression of the briquette;
- efficiency – high efficiency of the briquette press (up to 700 kg/h);
- ecology – the closed extraction system reduces emissions of pollutants and improves work safety conditions;
- high quality – control of parameters at each stage and precise control of the process ensure briquettes of excellent quality;
- versatility of applications – briquettes can be used in boilers, ovens, fireplaces, power plants, and industrial plants.
Operation of the complete line:
- raw material is fed into the hopper of the KPS-600 calibrator/screw feeder;
- the calibrator separates contaminants and fine fractions, and the cleaned raw material is transported by a screw to the piping of the SA-800 dryer;
- in the chamotte furnace, the hearth heats the chamotte bricks, which in turn raise the air temperature in the aerodynamic system of the dryer;
- hot air from the furnace is injected into the piping system, where it mixes with the dried material;
- the dried material goes to the PS-200 DUO feeder and is transported by screw to the BT-350 briquette presses;
- in the briquette presses, the raw material is pressed into briquettes;
- dust from the SO-2 extraction system is reused in the production process;
- the operator controls the line using control panels.
Components of LDB-350 DUO with SA-800 dryer:
- KPS-600 calibrator/screw feeder is a device used for calibrating and screening raw material, removing contaminants and fine fractions, ensuring accurate and efficient preparation of the material for further processing;
- chamotte furnace is a heating device that uses the combustion of fuel to heat chamotte bricks, which then release heat to the hot air, serving as an effective heat source for the dryer;
- piping system (SA-800 dryer) is a network of pipes used for drying and transporting dried material. Hot air from the furnace is delivered to the pipes, where it mixes with the material, and turbulent flow of air, generated by the special design of the pipes and the radial fan, ensures optimal drying conditions;
- PS-200 DUO screw feeder is a precise and efficient device for delivering raw material to the briquette presses. Two independent screws provide flexibility in the feeding process, and the inverter allows for precise regulation of the amount of material supplied, guaranteeing optimal briquetting parameters;
- two BT-350 briquette presses are efficient machines used to press dried raw material into briquettes. The raw material fed into the hopper is subjected to the action of a piston, which injects it under high pressure into the forming sleeve. Interchangeable forming sleeves allow for the regulation of diameter and degree of densification of the briquette, adjusting it to individual needs;
- closed extraction system SO-2 is an efficient solution for removing dust and contaminants generated during production. The extracted dust is not released into the atmosphere but is redirected back into the production process, significantly increasing its efficiency and reducing material losses;
- control panels allow monitoring the operation of the entire line, monitoring parameters, regulating the process, and protecting the motors. Displays, ammeters, and other instruments provide precise information about each stage of production. Thermal protection systems ensure safe and efficient operation of the devices.
LDB-350 DUO Line with SA-800 dryer is the ideal solution for:
- companies and private individuals looking for an efficient and ecological source of heat;
- enterprises dealing with waste processing and recycling;
- agricultural farms and greenhouses looking for alternative energy sources.
Advantages of briquettes over loose biomass:
- higher combustion efficiency – more heat from less fuel (10-20% higher calorific value);
- reduced emissions – less smoke and dust, 2-3 times less ash;
- easier transport and storage – compact and dense briquettes take up less space and are less prone to damage;
- versatility – used in boilers, stoves, fireplaces, power plants, and industrial plants;
- renewable source of energy – biomass is a sustainable fuel that protects the environment.
