Model YL belt press filter is a kind of up to date sludge dehydration equipment which is developed through introduction and absorption of advanced technology from the USA. It has remarkable characteristics such as large disposal capability, high efficiency of dehydration, long service life, very low sludge loss and power consumption, etc.
I. Advantages 
1. Automatic control and continuous operation;
2. Very low power consumption and long service life;
3. High efficiency of dehydration, high concentration of mud cake, over 35%-40%;
4. Easy to manage and convenient to service.
II. Performances:
The scientific design and reasonable layout make sure the belt press filter have efficient dehydration ability. The main dehydration press rolls adopts the apertured design. It not only increases the processing ability, but also makes the sludge dehydrated speedily on both sides of the filter belt to shorten the dehydration hours. The best combination between the pressure and shearing force is assured with the arrangement of press rolls which turn smaller at the back and the change of contact angle of filter belt. Thereby, the paper pulp density and dehydration efficiency are greatly improved.
III. Features 
The tension of filter belt is achieved by the aerated pneumatic tyre and the tension for the whole belt is constant. At the same time, it will not evoke any tension change caused by the change of feeding quantity. Therefore, it is easy to operate and manage. This machine has the air pressure control system which checks the position of filter belt on the press roll and corrects errors automatically.
