（1）Chinese first high-pressure briquetting machine (GY750-300)was successfully manufactured in 1989.
（2）Fully product range with roller diameter of 520-1200mm could be provided.
（3）High line specific pressure of 11T/CM is forced to design on pre-pressing.
（4）The material has a good extrusion effect with high pelletizing ratio and high density briquettes.
（5）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.
（6）Adopting dual-output shaft reducer structure to improve the accuracy of the double rollers.
（7）Completely-sealed gearbox is used with low noise and without oil leakage.
（8）Fully using ball groove alignment structure of high-pressure briquetting machine for more convenient adjustment.
（9）Adopting hard-tooth-surface gears to greatly improve using performance and life.
（10）Adjustable-speed motor is used for preforming press.All wear parts are overlaid with wear-resistant alloy to improve service life.
（11）The stand-alone hydraulic station can adjust pressure and have the special function of overpressure protection.
（12）Finished briquettes forming lab is ready for customers to provide professional testing with specific datas.
