"In recent days, a one-time trial of a new type of mechanically ground wood pulp rotary screen dryer designed and manufactured by the Hunan Yueyang Paper Group's pulp mill has been successful. It has the advantages of reasonable structure, smooth operation, uniform sizing, and obvious dewatering effect. Compared with the previous reduction of nearly 20,000 yuan, the pulp concentration after dehydration increased from 0.9% to 5% or more, fully meeting the quality requirements of mechanically ground wood pulp.
The technicians of Yuezhi Machine Shop aim at the traditional dewatering machine cage made up of multiple spokes, copper plates, copper strips, copper wires, etc. The structure is complex. Copper wire wear blocks and copper strips are easy to loosen and break, making maintenance difficult. , high consumption, high maintenance frequency and high cost. After extensive collection of data and peer experience, the new network will be changed to a hollow shaft, reduce the number of spokes, to replace the original mesh cage with a stainless steel plate with a hole in the original cage, copper, copper wire. With the elimination of a more expensive copper material, each dewatering machine can save nearly 3,000 yuan, while simplifying the structure of the cage and reducing the weight by 1/3, greatly reducing the difficulty and cost of maintenance, and the service life is also reduced. Effectively extended. The application of this new type of cage is the first time in the country. It is the ideal dewatering equipment for mechanically ground wood pulp. ""
