i. overview
with the increase of china’s paper yield and the adjustment of raw material structure in china, the more and more waste paper (deinked) pulps have been produced in recent years. to get the products with high-efficiency and low energy-consumption, with several years of waste paper (deinked) pulp treatment experiences summarized by our company, the patented super-efficiency flotation-deinking machine for waste paper deinking is developed.
ii. application
this machine is used for waste paper (deinked) pulp treatment, and can effectively remove the ink, light impurities and stickies from the pulp.
iii. features and advantages
1．high flotation efficiency, high scum concentration,the ink discharge concentration is adjustable, and thus it can greatly reduce the loss of fiber in the scum.
2. easy-to-operate-and-maintain, low power consumption, low operating cost which is 1/10 of operating cost of the vertical enclosed and horizontal distribution (tank type) flotation tank. it is currently the most advanced deinking machine in china and overseas.
3. the internal circulation of pulp is completed in this machine, with high usage of air inside the pulp, and the proportion of the air and pulp can be adjusted.
4．high flotation quality, low energy consumption, with unique gap separation structure and multiple-stage flotation of the pulp, the mutual mixing of different pulps is avoided.
5. the machine is free from cleaning with water during normal operation, and a special non-clogging aeration unit is used to avoid the backflow of the pulp. the instantaneous starting and stopping of the machine are available.
