Belt filters are made up of two permeable belt filters that are operated by the press shaft. Belt filters are one of the most commonly used equipment in the mining industry today and are of great help to mining dewatering.

Firstly, two drum type pre-dewatering machines are used for pre-dewatering. In the pre-de-watering machine, the sludge particles mixed with the flocculant remain in the machine and the water flows out through the filter cloth. After the sludge accumulates to a certain amount, From the exit of the pre-dehydrator to the belt filter.

In this process, pre-dehydration process is very important, can increase the pressure of the sludge containing solid concentration, the belt press dehydration efficiency. After the pre-dehydrated sludge inlet belt filter press, the first procedure is gravity drainage, this procedure is to once again increase the solid content of sludge to prepare for the next working procedure.

After gravity drainage, the sludge was again drained, and evenly distributed on the filter cloth, and gradually began to pressure. The thickness of the sludge on the cloth will depend on the nature of the sludge and the speed of the filter cloth.

Sludge pressure filter began, the sewage in the middle of two filter cloth, after a group of pressure shaft, the pressure generated by the filter cloth to dry, and filter cloth pressure can be adjusted according to the effect of dehydration.
