This is a kind of briquetting machine that is widely used in the industrial areas today. Those powdery materials and waste, which need to be used in the furnace; those fuel materials, which need to be formed together to get a better heating effect, and other materials, which need to be used as a shape like ball or pillow with certain size, etc. all need the roller-type briquetting machine to realize the briquetting work.

Since the first large high-pressure briquetting machine GY750-300 was finished trial-manufacture in1989,we have formed three series,more than twenty models after mant tears of research,tests and improvements.The structure,performance,quality and service life of products have reached a world-advanced level.

Advantages

Chinese first high-pressure briquetting machine (GY750-300)was successfully manufactured in 1989.

Fully product range with roller diameter of 520-1200mm could be provided.

High line specific pressure of 11T/CM is forced to design on pre-pressing.

The material has a good extrusion effect with high pelletizing ratio and high density briquettes.

Super wear-resistant roller surface is made by special bearing steel.This kind of roller surface has a good using effect and long working life.

Adopting dual-output shaft reducer structure to improve the accuracy of the double rollers.

Completely-sealed gearbox is used with low noise and without oil leakage.

Fully using ball groove alignment structure of high-pressure briquetting machine for more convenient adjustment.

Adopting hard-tooth-surface gears to greatly improve using performance and life.

Adjustable-speed motor is used for preforming press.All wear parts are overlaid with wear-resistant alloy to improve service life.

The stand-alone hydraulic station can adjust pressure and have the special function of overpressure protection.

Finished briquettes forming lab is ready for customers to provide professional testing with specific datas.

Feed the raw material to the hopper on top of the roller press, then it will go to the lower roller pressing area through gravity or a force feeding system.

In this roller pressing area, there are two same pressing rollers with ball-pockets on the surface, which rotate at a constant but opposite speed. When the material enters the bite angle between the two rollers, it is gradually compressed as the bite angle is reduced. At the moment when the two ball-pockets coincide, the briquetting pressure reaches a maximum and briquette is made. then, the two ball-pockets are opened and the briquette begins to elastically expand and fall off.

In the roll briquetting press machine, the raw material is pressed on both sides, and the pressure from each roller is the same.
