100 ton per hour screw classifier for washing sand

Screw classifier is used in the dressing plant to match with the ball mill to distribute the ore sand, or in the gravity dressing plant to classify the ore and mud. The particle size classification of the slurry in the metal beneficiation process and the desilting and dewatering of the washing Wait for homework. This machine has the characteristics of simple structure, reliable work and convenient operation.

The screw classifier is mainly composed of a transmission device, a spiral body, a trough body, a lifting mechanism, a lower bearing (bearing bush) and a discharge valve.

The water tank of the machine is installed obliquely. The inclination angle is determined according to the equipment configuration in the process flow. The transmission device drives the screw to rotate in the groove. After the fine slurry is fed into the groove from the side feeding inlet, a lower end is formed at the groove. The surface area and volume of the slurry settlement area are determined by the inclination angle of the water tank and the height of the overflow weir. The spiral of low-speed rotation can play a certain agitation. After the slurry is stirred, the light and fine particles are suspended on it to form an overflow, which overflows from the overflow surface of the trough and flows into the next beneficiation process; the heavy particles sink to the bottom of the trough to form a return. The sand is transported by the screw to the discharge port.

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.
