Belt filter press is popular slurry dehydration equipment, which can be classified into rotary drum thickening belt filter press and belts thickening belt filter press according to different design of thickening system. The rotary drum thickening system is to remove the liquid while rotating, after that the slurry will go to squeeze zone for further squeezing. While the belt thickening system will remove liquid by the gravity dewatering force on the filter belt, after that the slurry will go to squeeze zone for second squeezing.

The advantage of belt thickening belt filter press is that slurry can be scattered on filter belt evenly, the extra liquid will be discharged through pipes, the dewatered slurry will be sent to the squeeze zone. This work principle allows it adapts to more applications with lower slurry concentration. For example, rotary drum thickening system can handle slurry concentration >1.5%, while belt thickening system can handle slurry concentration >0.5%, which means belt thickening belt filter press is suitable to more applications and usages. And after dewatering, the filter effect of belt thickening belt filter press is as good as rotary drum thickening belt filter press. 

In practice, we have find that our customers are obviously favor of belt thickening belt filter press, which also improved that belt thickening system has its unique advantages.
