Characteristics of Indonesian kaolin clay

Indonesian kaolin has a long way to go from its origin to being usable in various industrial processes. Below we will see how it was created and where it comes from.

Kaolin gravity separation equipment

First, kaolin must be mined using water jets. The kaolinite is then centrifuged with a kaolin slurry, thereby removing the sand, and the kaolinite is ready for triple filtration, using 100 to 325 mesh screens.

The kaolinite is purified and solidified after being filtered by a high-pressure pump and a filter press. In this step, a kaolin block with a moisture content of 33% to 35% is produced.

If you want kaolin with a lower moisture content, it must be naturally dried until the moisture content is between 12% and 14%. This kaolin clay has a moderate moisture content compared to dry kaolin clay, which contains only 1-4% moisture.

Slove method of the clogging of trommel screen sieve

The drum screen is a simple screening device. The trommel screen is easy to close and collect dust, the maintenance is small, the maintenance is simple, and the service life is long. It is a device frequently used in refractory materials, coal, river sand classification, and sandstone classification. The advantage of the trommel screen is that the structure is not complicated so that the device can be quickly operated, and when the trommel has problems, people can easily solve it. But what should I do when the screen of the trommel screen is blocked? The following screen will introduce several ways to solve the phenomenon of blocking the net. The trommel screen sometimes adopts a mechanism added to the fixed frame, and then the mechanism rotates to drive the belt mounted on the belt to continuously smear the surface of the sieve hole, thereby sucking out the raw material particles blocked in the sieve hole. One of the disadvantages in practice is that it produces a lot ...

How to desilting municipal drains and canals?

The river channel sludge filter press is a special equipment, which is used to deal with river channel dredging sludge, lake sludge and sludge brought ashore by cutter suction boats. The equipment adopts the principle of automatic water removal and extrusion dehydration. First, the sludge is introduced into the equipment through a slurry pump, and after pressing and squeezing, the output is clear water and mud cake. This treatment method does not require manual unloading, and the moisture in the mud cake is effectively removed, which can be directly packaged and transported, and the clean water produced can be directly discharged. Automatic processing: The equipment adopts an automatic control system to realize automatic water removal and extrusion dehydration without manual operation, which greatly saves labor costs and time.
