Thickener Tank Require Regular Maintenance

Different operations of the concentrator have different requirements for the concentration of the slurry. Therefore, it is often necessary to change the concentration of the product during the beneficiation process. Today, more and more equipment manufacturers are starting to produce Thickener Tank. Golden Machinery provided concentrating tanks long ago. Thickening tanks commonly used in the market include three types of peripheral transmission concentrators and central transmission concentrators, as well as high efficiency deep cone multi-cone thickening tanks. Although these concentrating tanks vary greatly in structure and product quality, they are basically the same in terms of concentrating tanks.

The concentrating tank is mainly composed of a circular concentrating tank, a truss and its lifting device, a transmission device, an inlet and outlet device, and a signal safety device. After adding a certain amount of flocculant to the slurry for concentration, the solid particles in the slurry will form flocs, and the floc will gradually decrease under the action of gravity, and finally deposited on the bottom of the concentration tank to achieve solid-liquid separation. The mud at the bottom of the concentrating tank is discharged from the discharge port at the center of the tank bottom by a squeegee, and the upper clarified water overflows along the upper edge of the concentrating tank.

After the flocculant is produced, by adding a flocculating agent to the slurry, the ore particles form larger particles under the action of the flocculating agent, thereby increasing the sedimentation speed and improving the concentration efficiency. In some high-efficiency thickeners, a sloping plate is also provided, and the slurry enters the thickener from the bottom of the dense tank. The sloping plate reduces the settlement distance of the ore particles while stabilizing the slurry, and greatly improves the beneficiation efficiency. The bottom of the concentrating tank is usually designed to have a certain taper. Under the continuous scraping action of the squeegee, the deposit to the bottom of the concentrating tank moves to the center of the tank bottom and is finally discharged from the discharge hole at the center of the tank bottom.

Each user must be trained before using the thickening tank. After meeting the operational requirements, the tailings dewatering equipment can be operated. This reduces damage to the tailings dewatering equipment due to operational errors and requires periodic inspection of operational knowledge.

What are the Important Parameters of Thickener Tank

Thickener Tank are very important to mining plants, so we should have a comprehensive understanding of the aspects that affect the production capacity of thickeners. The capacity of the thickener means that the thickened area is treated day and night, and several factors affect productivity.

First, the density of ore and the discharge of ore; second, the composition of the particles; third, the viscosity of the foam; fourth, the presence of chemicals and electrolytes; fifth, the temperature of the mud; and sixth, the concentration of the material .

In addition to these factors, the most important factor is that mud is the most difficult substance in slime. There are two sources of mud: one is formed during the crushing process of the ore, called mud, and the other is produced during the grinding process, that is, excessive grinding, called production mud. Due to the fine particle size of the slime, the mineral surface area and moisture content increase according to wetting and capillary phenomena. The microcolloid particles are 0.1-0.001 mm, and the molecular force and electrostatic repulsion between the same charged particles are caused by their own sedimentation. This trend did not cause precipitation. Therefore, fine mud is the most difficult substance for mucus during deposition.

Understand the important parameters of thickening thickening tank: 1. The maximum particle settling velocity in the overflow: the sedimentation process of the ore particles in the concentration tank is very complicated and there is no accurate calculation method. The factors affecting the sedimentation velocity of the ore are the ore of density, particle size, shape and surface characteristics.

2. Concentration zone: In the actual work of design and production, the required concentrating area generally uses the sedimentation velocity of the largest particle in the overflow to calculate the concentrating area required for the operation of the concentration.

three. Concentration per unit area Concentrator: per unit area The processing capacity of a concentrator is generally selected according to industrial or simulation tests. If there is no test data, you can choose to refer to the actual production indicators of similar concentrators.

How to Maintain Mine Flotation Equipment

For equipment, productivity is the most critical, because users buy equipment to improve the economics of their own company, if you buy flotation equipment can not reach your expected value, you will feel the loss. Just like people, when they work for a long time, they will be exhausted and directly affect the efficiency of daily work. This also applies to mining Flotation Equipment. The Golden Machinery gives you some methods for the maintenance of mining flotation equipment.

By changing the hydrophobic (water repellency) or hydrophilic (water absorbing) conditions of the surface, it is possible to induce the mineral particles suspended in the water to adhere to the bubbles passing through the flotation device or to remain in the pulp. The bubbles are transferred to the upper surface of the pulp and form a foam which can be removed along with the attached hydrophobic mineral. This is the principle of flotation.

Maintenance of the flotation machine:

1. Adjust the amount of pulp. Use the tie rod to adjust the opening of the sand door to ensure the balance of the slurry and avoid the deposition of coarse mortar in the studio.

2. Adjust the page height. Adjust the level regulator to adjust the liquid level to ensure that the scraper effectively scrapes the foam and prevents the slurry from spilling into the foam tank.

3. Check the air intake. The amount of intake air has a great influence on the performance index of the flotation machine, which is closely related to the wear of the impeller and the cover plate.

4. Replace consumables in time. For consumables, it is necessary to check frequently to prevent large losses caused by small losses.

The quality of the flotation machine is directly related to the level and output of the flotation indicator, which is crucial for mine production. Therefore, the flotation machine must always be strict in installation, operation and maintenance.

Five Maintenance Principles for Flotation Equipment

In the flotation process, the flotation machine is an important equipment, because the main function of the machine is to separate non-metallic materials, such as fluorite, and non-ferrous metals, the role of the machine is growing in the mineral processing industry. The important thing is irreplaceable. It is precisely because the role of the machine is so obvious that we should pay more attention to it. In order to make the machine work well, we must pay attention to the normal maintenance of the machine. Zhejiang Golden Machinery Factory provides the daily maintenance point of the Flotation Equipment.

1. The working capacity and duration of the flotation machine are the same as those of other machines. It is determined by the maintenance and maintenance of the main components of normal work. All parts of the work should be carefully inspected for 3-4 months and in the new flotation machine. Regular inspections during the first few months of work;

2. Only technicians can check.

3. In order to replace consumable parts in time and reduce downtime, it is necessary to keep a complete set of consumable parts in the warehouse. According to the specific circumstances, determine the date of use and the amount of reserves of consumables.

4. Check the air intake. Air intake has a significant impact on the performance of the flotation machine, but air intake and wear on the impeller and cover are reduced, so air intake from the flotation machine is often detected by an anemometer in production.

5. Replace consumables. Replace consumables in time. When replacing the impeller and cover, ensure axial clearance and assembly quality.

Good maintenance not only extends the life of the flotation equipment, but also increases the efficiency of the flotation equipment. Zhejiang Golden Machinery Factory recommends that you regularly maintain flotation equipment, and other equipment maintenance is equally important, such as Mixing Equipment and concentration equipment.

How to Use Flotation Equipment Smarter

For a long time, flotation has been the core of the mineral processing industry, solving the “sulfide” problem of the early 20th century. Many factories provide Flotation Equipment, including Zhejiang Golden Machinery Factory. The intelligentization of the flotation machine can greatly improve the performance of the equipment and improve the efficiency of flotation. Flotation equipment is currently one of the most important mineral processing tools.

Most flotation circuits include the initial phase of coarse flotation followed by the cleaning phase of flotation. The purpose of the coarse and collector flotation circuits is to maximize the recovery of the desired minerals into relatively low grade ore concentrates, which typically contain 5-15 weight percent of ore material (with ore) and are directly flavored. Related. Depending on the specific mineral release characteristics of the coarse concentrate and the collector concentrate, these concentrates can be recycled prior to upgrading in the subsequent stages of cleaner flotation.

Sometimes the harmful elements found in the ore body are themselves highly hydrophobic and need to be removed at the beginning of the flotation, otherwise they will be reported along with the valuable minerals to the concentrate and affect the concentrate grade. Mineral species such as talc, carbon and carbon-related minerals, such as carbonaceous pyrite, are difficult to suppress in flotation circuits. On the other hand, putting them in front of a pre-floating circuit is an easier way.

With the advancement of flotation technology and equipment, many major changes have taken place in the industry over the years. Other changes are more subtle, but equally important. One of them is to design a flotation circuit that takes full advantage of the release of minerals and the role of surface chemistry. In many cases, it is not a “bigger is better” problem, but it becomes more intelligent in the application of flotation technology.

Thickener Tank is a Widely Used Separation Device

In the ore sorting process, the beneficiation process is a very lengthy process. If we regard the entire beneficiation process as a huge network, the pulp is the blood in this network, and the slurry pump in the process of slurry transportation is The source of power, the pipeline through which the slurry flows is the skeleton of the entire network, and Thickener Tank(concentrated large well)is the intermediate transfer station of the entire network.

Since the ore will input a large amount of water (such as magnetically selected flushing water) during magnetic separation or re-election, the concentration of the slurry before flotation is too low, which is far from meeting the concentration requirement of flotation, so it is the main flotation. the reason. In the floating before the operation, an efficient concentration device is set as the slurry concentration dehydration device.

The concentration tank is a widely used solid-liquid separation equipment, which is the main equipment for the concentration process in the fields of plant selection, sewage treatment and chemical industry. In actual production, there are a variety of mineral processing equipment, which are used in the production process and also in experimental research. In a laboratory concentrator, a high efficiency concentrator is a typical structural device, taking it as an example. Introduction to the principle of laboratory concentrator

A cross-shaped truss is arranged on the central vertical axis of the bottom of the pool, and the bottom of the truss is a scraper. When the concentrator is working, the truss is continuously scraped by the hydraulic motor to the bottom of the mud, which is due to the pool. The shape of the bottom is tapered, and finally the mud is discharged from the outside to the center of the bottom of the pool, while the upper water enters the overflow. The concentrator device automatically senses the pressure sensor signal by the core PLC, and the operation is simple and flexible.

Introduction to the main Advantages of Efficient Thickening Tank

High-efficiency Thickening Tank are also called thickening tanks. Compared with traditional concentrating tanks, concentrating tanks have the characteristics of deep cones, and the height of equipment is significantly higher than other concentrating tanks. The machine is mainly composed of a deep cone, a feeding device, a stirring device, a control box, a drug delivery device and an automatic control system. So what is the difference between the principle of concentration and ordinary concentrating tanks? Zhejiang Jinji Factory will take you to understand.

Generally, in order to obtain a good compacting effect, it is necessary to go through three indispensable stages, namely, a coagulation destabilization stage, a coagulation granulation stage, and a filtration compression stage. If the flocculation is insufficient, the solid-liquid separation will not achieve the desired effect.

The same is true for effective concentrating tanks. The slurry is flocculated in a concentration tank. After the large flocs in the slurry are increased to a certain amount, the bottom of the thickener forms a desired dense phase layer. The slurry is subjected to the pressure of the squeegee, further concentrated, and then discharged through a discharge port. At this time, the pulp is already a high concentration concentrate, which can be further filtered, and at the same time, the tailings with higher concentration are discharged, which greatly improves the recovery rate and helps the enterprise to achieve an efficient production mode.

The bottom of the concentrating tank is usually designed to have a certain taper. Under the continuous scraping action of the squeegee, the deposit to the bottom of the concentrating tank moves to the center of the tank bottom and is finally discharged from the discharge hole at the center of the tank bottom.
