High pressure roller briquetting presses are designed to produce briquettes from various powder raw materials: coal fines and coal dust, lime powder, soda ash, various salts, sodium carbonate, fluorite powder, slag after smelting aluminum, iron powder, converter dust, ferrosilicon powder, chromium powder, magnesium powder, powder of refractory materials and other raw materials. Also, it is successfully used to obtain fuel briquettes from various organic raw materials including charcoal.
The resulting briquettes are highly durable, convenient for transportation, provide efficient processing and using of raw materials. Briquettes obtained using dry briquetting under high pressure can have various shapes: oval, egg shape, pillow shape, cube shape, etc., in accordance with customer requirements. The performance of briquetting presses can also vary in the range from 1 to 20 tons per hour.
The main technical parameters of the roll briquette press are presented in table. 1 using the ARP-1 model as an example.

Photo 3: Roll press for dry granulation
Dry granulation equipment allows to compact powder particles of various raw materials into granules of a certain size. In dry granulation, the powder mixture without the addition of liquid is compacted by applying considerable force to the powder.
Today, granulation is used very widely in various industries: in the chemical, petrochemical, pharmaceutical and metallurgical industries. Also in agriculture, one of the most popular applications for granulating raw materials is the production of granular fertilizers and feed. To date, the production of fuel pellets from waste wood and the agricultural sector (husk, straw, etc.) is very common.
