Newsprint Paper Project Calender for Paper Mill

calender

The cultural paper and newsprint paper project calender is a complete paper making machine solution for the finishing section. This cultural paper and newsprint paper project calender uses a dual-zone design with two nips. One nip has a controlled crown soft roll at the bottom and a heated hard roll on top. The other nip has a soft roll on top and a hard roll at the bottom. This design lets the cultural paper and newsprint paper project calender treat each side of the paper independently. The hard rolls are made from alloy forging with 35CrMo shafts. They have a large diameter that creates a wide nip with low pressure. The soft rolls have high-performance composite covers. The cultural paper and newsprint paper project calender also includes a hydraulic system with a large stainless steel tank, high-precision filters, and imported HAWE valves. A thermal oil heating system with PID control provides accurate temperature control. The cultural paper and newsprint paper project calender is compact and built for safety.

The cultural paper and newsprint paper project calender uses a large roll diameter to create a wide nip with low pressure, keeping the paper’s bulk while increasing heat contact. The hard roll has a two-inlet, one-return design that keeps the surface temperature even across the whole roll. The cultural paper and newsprint paper project calender’s hydraulic and heating systems are controlled from one easy-to-use screen. A double safety system protects the operators. The hard and soft rolls can be interchanged because they use the same bearing housings.
