The GY series high pressure double shaft briquetting press machine are developed on the basis of common dry powder briquetting press machine, after continuous improvement, especially in reducing energy consumption, improving the briquette quality and compactness; Adopting the double-output shaft reducer structure improves the roller’s precision; Using hardened surface gear to improve the reducer’s working performance and service life；Pre-pressure system adopts the speed adjustable motor; All wear-out parts are welded with wearing-resistance alloy material; The hydraulic station is placed independently with the function of pressure-adjusting and protective function when pressure overloading. The final briquette get from double shaft high pressure briquette machine have high briquetting rate and high briquette strength. Through Forced pressurization, pre-compression screw forced feed, made high hardness briquettes (such as magnesia, bauxite, dolomite, iron powder, etc.). It is widely used in metallurgy, chemical industry, coal and refractory industries. Especially used in steel plant for make lime , iron , Steel slag ,Steel scrap , fly ash , sludge etc

1.Raw materials can be pressed well with high ratio of briquetting and high strength of pressed briquettes; Better application result of roller surface, longer service life;
2.Adopting the structure of dual-output shaft reducer, improving the roller precision, using hard surface gear to improve the working performance and service life;
3.Pre-pressing adopts the speed-adjusting motor; all wear-out parts are welded with wearing-resistance alloy to improve working performance and service life;
4.Hydraulic plant is placed independently with the function of pressure-adjusting and protective function when overloading.

The materials are pressed into the pre-press device of the briquette machine with certain volume evenly when working, and the stable material position shall be kept in the pre-press device. The pre-pressing spring in the device will force the materials into the inter-space between the double rollers, then the materials shall be pre-pressed and transited to the arch groove of the pair-rollers. The roller pits with the same shape are distributed evenly on the roller surface. The 2 pair-rollers shall rotate at constant speed reversely through engagement drive. The rollers will suck the materials at the entry into the groove and forcibly compress them. With the continuous rotation of the pair-roller, the ball shall be taken off by the elastic force and gravity. The roller rotates to compress and form the materials periodically with the continuous operation of the motor to realize the batch production.
