Horizontal screw centrifuge It is widely used in slime treatment. Coal slime is usually a complex slag slurry produced in the process of coal mine processing, which contains a large number of solid particles and water. During the process of processing coal slime, it is necessary to separate the solid particles from the water, so as to realize the dewatering and Solid-liquid separation 。
Use horizontal snails Centrifuge The steps are as follows:
1. Preparation: check whether the equipment operates normally, and ensure that the inside of the machine is clean and the spiral knife plate is not damaged.
2. Adjust the operating parameters: according to the type and requirements of the slime to be treated, adjust the operating parameters such as rotational speed, feed rate and the switch position of the slag outlet. The adjustment of these parameters can be optimized according to the actual situation and needs.
3. Feeding: slowly inject the slime to be treated into the feeding port of the horizontal screw centrifuge, and pay attention to controlling the feeding speed to avoid exceeding the processing capacity of the equipment.
4. Separation: The coal slime passes through the rotary movement inside the centrifuge. Under the action of gravity and centrifugal force, the solid particles are pushed to the wall of the centrifuge, while the liquid is discharged through the internal screen.
5. Slag discharge: When the solid particles accumulate to a certain extent, open the slag discharge port to discharge the solid residues. Pay attention to control the speed of slag discharge so as not to affect the operation stability of the centrifuge.
6. Cleaning: After treatment, the horizontal screw centrifuge needs to be cleaned and maintained to ensure that the equipment can operate normally next time.
The application advantages of horizontal screw centrifuge in slime treatment are as follows:
1. Efficient separation: The horizontal screw centrifuge can quickly separate solid particles from liquid, improving the efficiency of slime treatment.
2. Environmental protection and energy conservation: effectively separate and recover water in slime, reduce water consumption, and also reduce environmental pollution caused by slime.
3. Good adaptability: The horizontal screw centrifuge can handle all kinds of complex coal slime, with strong adaptability.
In addition to separating solid particles from water, the horizontal screw centrifuge has the following applications in slime treatment:
1. Coal slime dewatering: The horizontal screw centrifuge can separate most of the water in the coal slime to achieve the purpose of dewatering. This can not only avoid waste and reduce transportation costs, but also reduce the burden of slime treatment.
2. Solid liquid separation: The horizontal screw centrifuge can also realize the purpose of solid liquid separation, so as to avoid environmental pollution and waste of resources. Solid liquid separation is an indispensable part in the process of coal slime treatment.
3. Recovery of coal slime: In the separation process, the horizontal screw centrifuge can separate the solid particles from the liquid, so that the recovered coal slime can be used for recycling, so as to reduce the waste of resources.
In a word, horizontal screw centrifuge is widely used in the field of slime treatment. It can improve the dewatering efficiency, separation effect and recovery rate of slime, and reduce waste and environmental pollution. However, the specific application depends on the characteristics and purpose of the slime treatment, which needs to be considered in the actual situation.
