Do You Know Coal Washer?

Depending on the quality of coal, coal needs to be "washed" with water and chemicals to remove sulfur and impurities before it is burned by power plants. It is generally believed that coal washing or coal preparation is an effective way to get the most benefit from coal that has never been mined. On the other hand, this is a water-consuming process: usually, it takes 45 cubic meters of water to wash one ton of coal. With the tightening of environmental protection laws and regulations, mechanized mining has increased the impurities in raw coal, the output has continued to soar, and the demand for improving the quality of coal has continued to increase.

Coal from coal mine is a complex material mixture with multiple physical properties. In addition to coal itself, this mixture also contains rocks, sand and various minerals. Therefore, coal must be purified before being sold to consumers. The cleaning process includes a series of steps, and finally produces products that are particularly suitable for specific consumer needs. The earliest of these steps is crushing and sorting. These two processes can reduce coal to a form that consumers need.

The coal washing plant has improved the coal washing process and the quality of coal washing, thereby increasing the price. Coal washing technology also helps reduce emissions from combustion.

Coal from the mine is a combination of a complex material and a large number of physical homes. In addition to coal itself, rocks, sand and different minerals are also included in the mixture. Therefore, coal needs to be cleaned before it can be provided to consumers. The cleaning program contains many steps that result in products that are particularly suitable for specific customer requirements. Among the earliest of these steps is crushing and also sizing, these two processes can reduce coal to the form required by customers.

Purpose of coal washing equipment:

1. Reduce water and energy-intensive coal production

The coal washing program includes factory installation and independent modules to optimize beneficiation capacity. In other words, this means maximizing ore recovery rates while using less water, energy or other consumables in the process.

Another important feature is water conservation. By enhancing water saving, zero discharge of wastewater and reducing carbon emissions, this solution helps to achieve a more sustainable process.

2. A more sustainable process helps reduce operating costs

To meet the needs of customers for greater flexibility and efficiency in sustainability. Our philosophy is to provide comprehensive solutions for the industry.

Structural characteristics of coal washer:

1. Standard length valve body can be used, and the combination shape can be selected according to the needs.

2. Coal washing technology-the use of CNC pneumatic valve, the coal washing has a high degree of automation.

3. Coal preparation method: double-amplitude pulse water flow, good bed stratification effect, and high clean coal output.

The Importance Of Slurry Pump Maintenance

Regular maintenance of the slurry pump can extend the wear life, help avoid unplanned downtime, and reduce the total cost of ownership for the end user. In the rigorous and demanding world of mining, slurry pumps often run to breakpoints before intervention. In the short term, this may seem beneficial, but in the long term, you may be doing your plant an injustice.

Regularly monitor the performance characteristics of the pump, so that you understand its operation, and provide sufficient time to take a measurement response, without failure and unplanned downtime.

From a preventive point of view, some tasks need to be performed regularly during pump operation to ensure that the pump runs longer. If abnormal sounds are detected, leaks or temperature or vibration spikes are found, more in-depth maintenance is required during the planned shutdown period before failure occurs.

Vibration

Every running machine will vibrate: put your hand on the refrigerator at home, and when the motor is running, you will feel a slight vibration. For most machines, vibration is one of the earliest indicators of machine health, so it is an important measurement indicator that requires close monitoring.

Different pumps have different vibration speed targets; for large pumps, the maximum target will be greater than that of medium pumps that treat water. Conversely, when solids are introduced into the fluid, the vibrations will increase in relation to the properties of the mixture and the duty cycle.

Vibration monitoring is about tracking trends on a regular basis to see if there are obvious changes.

Once the pump reaches its wear life, it is normal for its vibration readings to show an exponential growth curve and begin to increase gradually.

Bearing assembly

The bearing assembly is a key component of any rotating equipment. Generally speaking, the service life of the bearing assembly depends on the process and operation. When selecting bearing components related to hydraulic performance, the life of the L10 bearing should be considered. The increase in vibration and noise levels is a clear sign, which may be a problem with bearing assembly.

One of the main causes of premature bearing failure is insufficient maintenance of the gland seal, which may cause leakage and spray slurry and water directly onto the bearing assembly. This can be reduced by regularly adjusting the seal and applying correct and consistent lubrication.

Throatbush and impeller adjustment

The wear rate of the throatbush has a significant impact on the overall efficiency of the slurry pump. In many applications, it has the shortest life compared to other components.

The importance of adjusting the throatbush to ensure the best clearance between the impellers is crucial. Define the root cause

It is worth noting that the drop in efficiency is not always a pump problem. The operating parameters need to be analyzed and the application evaluated to determine the root cause.

Can Coal Washing Be Done

Today, coal supplies one-third of the world's energy, and power generation accounts for 38%. In addition, the production processes and energy needs of industries such as steel, cement, fertilizer, pulp and paper all rely on coal. In view of the status of coal in the global energy framework and the reasonable environmental concerns associated with it, the technology for producing clean coal is essential to achieve efficient energy production and reduce environmental footprint. This is where coal washing comes in.

Sustainability and cost/operating efficiency can and should go hand in hand. The coal washing solution is designed to meet our customers' needs for greater flexibility and efficiency in terms of sustainability. Modularity makes the solution highly scalable to meet the needs of individual customers. When transporting equipment to remote locations with minimal infrastructure, it is particularly beneficial to have a compact and portable solution, as more and more coal producers are doing this kind of work.

Work together to innovate and create a more efficient tomorrow

Since the use of coal will continue to be large in the future, governments and industries all need to make greater efforts to develop environmentally and socially more sustainable and effective technologies to ensure that coal becomes a much cleaner energy.
