Double Shaft High Pressure Briquette Machine

The GY series high pressure double shaft briquette 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, Reducer part

The reducer connect power and press roller. Transport pressure from motor to roller. Compare to common briquette machine the reducer of this briquette machine is different and special.

There is a safety pin between reducer pulley and reducer, the purpose is to protect the pressure briquette machine overload, when the briquette machine overload, the safety pin will be cut off, briquette machine power off, all machine stop running (including reducer).

The reducer for this briquette machine is special, heavy heavy-duty hardened reducer, compare to common ZQ GB 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.

This reducer designed pump lubrication, a steady stream provide lubrication of gear reducer, bearings.

2.The coupling part

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.

Because the briquette machine work principle is use two drive shape make high pressure of briquettes. The reducer is double-shaft reducer, two shafts’ relative position is fixed. As there is a adjustment range between two rollers, to solve the roller can’t fixed by the fixed relative position of reducer shafts, this machine’s coupling Internal teeth and curved teeth work together structure. The curved teeth has a adjustment range, so it is well solved the problem of the position of two reducer shaft is fixed.

3. Double drive shaft device

Two drive shaft of reducer connect briquette machine shafts through coupling, made this machine double drive shaft structure. The advantage of both two shaft are drive shaft, make pressure evenly when press roller working, get better briquettes quantity.

The common briquette machine has one drive shaft and one passive shaft, there has a force of passive shaft always in diagonal downward direction. Therefore, when the material into briquette machine is wet or dry and unevenly stirred , There will be a small amount of briquette on the passive pressure roller ball socket off is not complete, some briquettes not look nice. The double drive shaft device avoided this kind problems.
