The GY series high pressure double shaft briquette press machine are developed on the basis of common dry powder briquette 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.
Name: Screw force prepress
Brand:Sinolion
Motor: Speed adjustable motor
The raw material will be prepressed by the screw force prepress under high force. The speed adjustable motor will control the screw speed and the work forc. The briquette density ,strength and hardness will more high use pro-loading syetem .
The reducer for this briquette machine is special, heavy heavy-duty hardened reducer, compare to common single-shaft output reducer, this reducer is a dual- shaft reducer to ensure two pressure shape of briquette machine are both drive shaft (the difference between the drive and passive shaft with the conventional pressure ball machine), the operation is more stable.
Name: Coupling
Function: connect reducer and machine
The coupling connect reducer and main machine, it has different structure with common briquette machine.
The coupling on common machine is a regular flanged coupling only connect two shaft and total two coupling. But the coupling of this machine is four sets, all them is Internal gear teeth curved sleeve coupling.
Name: Press Rollers of briquette machine
Material: 9Cr2Mo
Surface hardness: HRC58-62
The material of press rollers confirmed it has enough abrasion resistance and hardness. The roller make briquette machine get high strength briquettes, meantime improved the working life of press rollers.
The hydraulic device working together with other power parts together, make sure the work pressure of briquette rollers is enough.
The Max thrust of double shaft high force briquette machine can be 500 T. It confirm that the briquette quality is very well.
Meantime the hydraulic device can 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.
