Brief Introduction:
Three-drum
dryer is also called three-cylinder dryer and
triple-Drum Dryer. It has improved internal structure of monocular
dryer, which prolongs the time of pre-drying of wet materials and wet materials
in the machine, thus improving 50% to 80% of production capacity compared with
original monocular dryer.
Features:
1. The
needed investment is only 1/6 of foreign import product.
2. The final
moisture of the materials is ensured to be below 0.5%, making it the first
choice of dry-mixed mortar and slag powder production line.
3. The self
heat preservation heat efficiency of the cylinder can reach as high as over
70%, thus improving the heat efficiency by 35%.
4. The fuel
can be coal, gas and oil, and it can be used for drying lump, granulous and powdery
materials whose granularity is below 20mm.
5. Compared
with monocular dryer machine, its floor space is reduced by about 50%,
infrastructure investment reduced by about 50% and electricity consumption
reduced by 60%.
6. The
needed final water content index can be easily regulated according to
customers` requirement.
7. The
temperature of the air out is low and the service life of the dust removing
equipment is long.
8. It needs
no rack wheel and pinion driving, but uses riding wheel for transmission.

The Xinchang County is the country's largest bearing ring manufacturing and processing base for the use of industrial websites and the promotion of industry information work. This year, the Xinchang Bureau took the three major alliance standards as the starting point to promote the transformation and upgrading of the bearing industry. First, on the basis of the provincial-level outstanding project of the Bearing Ring Technical Terms and Standards Project last year, the Group further increased the use of promotion, expanded the use of the surface, and improved the block economic quality. Currently, the standard enterprises for the promotion and implementation of bearing rings have reached 70 The second is to vigorously promote the use of "Xinchang bearing" Zhejiang regional brand name use criteria for access standards, the county has nine companies authorized to use the assessment "Xinchang bearing" Zhejiang regional brand name signs; third is to actively start the bearing ring The CNC lathe union standard project has passed provincial approval and is being actively implemented.
The formulation and implementation of the three major alliance standards have effectively promoted the transformation and upgrading of the Xinchang bearing industry. Some companies have been recognized as qualified suppliers by world-famous bearing companies such as SKF. The products are exported to the United States, Switzerland, Japan, Korea, France, Italy and other countries. According to statistics, from January to October this year, the total output value of the bearing industry in Xinchang was 97.19. Billion yuan, a year-on-year increase of 14.95%, and sales revenue of 9.55 billion yuan, a year-on-year increase of 18.5%.
