Pulpers & Agitators

What are pulper and slushing machines used for in the paper industry?

The pulper and slushing machines are at the very beginning of the manufacturing process for paper, board and cardboard in stock preparation but also in the approach flow system.

A drum pulper is often used in waste paper processing because it dissolves the waste paper very gently.

Why is the design of agitators so important?

The task of an agitator is to keep the suspension in the chests and tanks moving so that a homogeneous consistency is ensured. It must be prevented that the stock suspension stops. Stock suspensions and fibers have the property of dewatering in the chest, which poses great problems in papermaking process. The design of the chest is also important. The chest and tank size and the size of the agitator are directly related. The importance of the chest and the tank is often underestimated and considered only as a storage tank, but the chest and the tank also have a technological function.
Used agitators and second hand agitators are often used for new projects as well because they are easy to acquire.
