How to Deal With Paper Sludge

There is a lot of sludge produced in the waste paper pulping line. If it is not treated effectively, it will have a great impact on the environment. So, what are the methods to deal with the sludge?

Equipment For Hot Disperser And Kneading

Waste paper contains in addition to all kinds of heavy impurities, also contains the asphalt type, paraffin wax, grease and all kinds of hot melt glue stick, these hot melt type impurity does not remove easily stuck to the net, felt, roll, or dryer cylinder, reasult in sheet break holes. Therefore, these impurities need to be treated.

How to choose paper machine oil

Because of papermaking machinery is to develop in the direction of large-scale, continuous, automatic, paper width and the speed of paper machine has been greatly improved, bearing the speed increase, more and more paper machine customer begin to choose lubricating oil in the system as a whole, rather than choose grease as bearing, gear lubrication of the medium in the system.
Therefore, the following factors must be taken into consideration when selecting paper oil:

(1)Hydrolysis stability: moisture is one of the biggest hazards in paper machine lubrication system, when a tiny crack on the surface of the bearing contact with water, the rate of bearing fatigue increases, cause pitting, early failure and abnormal downtime, caused huge losses.
High quality paper machine cycle lubricating oil must have excellent hydrolysis stability, to choose the right product and the first-class the system maintenance can help reduce the water enter the bearing seat, prevent premature failure of the bearing fatigue.
(2)Filter: it is time-consuming and expensive to replace the filter, and high replacement frequency is the signal that the oil filter is poor and the system maintenance is poor.
(3)Stable viscosity: because the bearing in the paper machine runs at a high temperature for a long time, it is important to ensure the stability of the oil in the transportation and operation. The key is composed of oil to have good oxidation stability and thermal stability, at the same time, centralized lubrication system design should have heating/cooling unit, maintain a relatively constant temperature system, to ensure that the oil viscosity.
(4)Deposition control ability: when the oil is aged, they will be decomposed by various mechanisms to form by-products, which will affect the performance of oil products. These by-products will increase the viscosity of the oil and plug the screen.Therefore, the oil formulation must have good sediment control ability.

By pressing and drying methods in the process of paper making will break away of the moisture in the paper, in this process because of various reasons lead to dehydration, so what are the measures to solve paper machine dehydration bad?

Paper Machine Drying Section

After the paper is pressed, the dry paper is generally around 40%. In the new press, the high can reach 50%, and the residual moisture must be evaporated in the dry part of the paper machine. The evaporation process requires a lot of heat energy, which is usually supplied by steam. The drying part is usually the most energy-consuming in the paper machine. The heat energy is transferred from the steam to the paper, and the commonly used equipment is the dryer.

Rewinder Machine for Papermaking

Rewinder machine adopts PLC computer programming, it can produce paper rolls full automatically with high speed. The finished product is neat and in good order. The production process is unwinding–embossing–perforating–cutting. Price is very favorable.
