China Drying Network Co., Ltd. 70T drying drying cylinder was successfully commissioned in Hanshou Industrial Park. The drying cylinder is the largest drying cylinder of Zoomlion's capacity so far, marking that Zoomlion dry mortar technology has risen to a New steps.
The 70T drying cylinder adopts the most advanced "three-pass technology" in the country and can accommodate 60T-70T materials for drying at the same time. Compared with the traditional single-tube drying cylinder, the thermal efficiency of the 70T drying cylinder has increased by more than 40%. 70T drying drums are more advanced than 50T drying drums. First of all, the angle of the lifting plate is increased so that the material can be stirred and dried more fully. Secondly, the 70T drying cylinder is longer by nearly two meters, so that the material can approach the length of 6 meters in the drying cylinder to ensure the quality of the material drying. At the same time, the output of the 70T drying drum is more than 20% higher than that of the 50T drying drum. Finally, the manufacturing process of the 70T drying cylinder improves the circular runout error of the roller and ensures the smooth running of the cylinder. The 70T drying drum uses 4 sets of 11KW motors to solve the problem of high temperature and high heat generation of the motor, and the thermal efficiency is also correspondingly improved, which can help customers save production costs.

Drying dryer
The general drying drying cylinder mainly consists of a drying cylinder, a feeding blade, a feeding box, a discharging box, a driving device and the like. The drying cylinder adopts technical measures such as integral welding, optimal length-diameter ratio and external thermal insulation layer. The internal guiding device has been specially designed to ensure the best combustion space; the use of the German Benninghoven burner has been adopted in the friction wheel driving method. Highly intelligent fuel-saving features and super-adjustable range ensure that stones with different water contents are fully dried. At present, the drying cylinders adopt a rotating long cylinder structure, which is made by welding heat-resistant boiler steel plates. Two large rollers are supported on the front and rear of the outer wall, and the large rollers are supported on the chassis by a tug wheel. The installation of a drive gear drive between the two rollers is used more in small and early equipment. More than medium-sized devices are driven by chain drives instead of gears, and their structural cartridges are easy to manufacture and install. For large-scale equipment, frictional drives are generally used, and four tugboats are provided with driving wheels: To increase the driving force, some models also attach rubber on tugboats.
Wood pellet machine is applicable to materials which is difficult to mold and bond, such as rice husk, sunflower seed husk and peanut shell, branch, trunk, wood rind, crop straw. The pelletized product can be used in the biomass fuel plant, power plants, timber processing plants, fertilizer plant, and chemical plants. This product is a satisfying compression molding equipment with low capital cost, quick profits and free risk.
