The milling-drying unit AS-4-2000

The unit AS is designed for simultaneous milling and drying plant materials. AS-4 very good proven itself in the following technological processes:
1. Drying and grinding of biomass in the production of solid biofuel (fuel granules and briquettes).
2. Drying and grinding of freshly cut grass in the production of granulated vitamin-herbal flour.
3. Drying and grinding of alcohol and beer production by-product, sugar beet pulp in the production of forages for animals.
4. Drying-grinding dung, manure, compost in the production of organic fertilizers.
5. Grinding of wood waste into flour in the production of wood-plastic composites (WPC, “plastic wood”) and other products.
6. Preparation almost from the any biomass (wood waste, lignin, peat, agricultural waste, including manure) dry fine-dispersed flour for further high efficient combustion in the dust burners of boiler-houses, power plants and CHPP (thermal power plant).

As well as can be used for super-thin comminuting (pulverizing) of wood or other plant materials in the process of the production of liquid biofuels, solvents (biobuthanol, acetone, etc.) and hydrogen; for drying and superfine grinding herbs and other vegetable raw materials in the pharmaceutical industry (in the process of production of drugs in this dozens of times increases the speed and efficiency of extraction, instant and low-temperature drying ensures maximum safety of useful substances).

Structurally, AS-4 represents steel rectangular, inside which there are high-speed activator and special guides. Movement of raw materials inside the machine is organized in such a way that the particles of the processed material feel the blows of the activator and the multiple mutual collisions. These repeated collisions and mutual friction lead to the crushing and simultaneous heating of raw material that, ultimately, leads to his drying. For the holding of raw materials in the chamber up to the moment of reaching the necessary moisture or the particle size is specially developed system of dynamic classification. The air stream inside system is separated from the external environment by star valve. The capacity of the AS-4 depends on the moisture and the size of the particles of raw materials at the entrance, the necessary final moisture and the degree of decomposition of the material. When submitting to the unit hot air capacity of drying significantly increases, the cost of electricity per unit of ready product is decreasing.

The advantages of the AS in comparing with lines of drying and grinding based on drum dryers.
1. Highest energy efficiency and, as a consequence,- the economy. The productivity of the unit 1 t/hour (at drying-crushing of wood chips) main engine power is 75 kW, total capacity of the other 3 engines - 29 kW. The real used power - about 70 kW !!!
2. The ability to precisely control the final particle size and moisture of processed material.
3. High degree of automation, ease of management and maintenance of the preset parameters of process of drying-grinding.
4. Smaller quantity of elements of the equipment and, as a consequence, greater reliability.
5. Maximum fire safety.
6. Maximum compactness (AS with capacity of 1 t/hour without HG takes only 6 m2) and, as a consequence, much less expenditure on buildings, foundations, transportation costs etc.
7. Maximum factory readiness - the low cost of installation (takes a few hours of working time).
8. Low operating costs due to the minimum quantity of wearing parts.
9. Minimal downtime for the replacement of quick-wearing parts.
10. Maximum the ease of maintenance.
11. The possibility of the manufacture of mobile (container) version.
12. High plasticity of the finished product that increases the productivity of the pelletizing or briquetting line and reduces wear of equipment details!!!
