Affecting Factors to Lifespan of Vertical Roller Mill

Le 8 mai 2018, 11:56 dans Humeurs 0

Building material market is booming with urbanization development, and that also leads to the development of vertical roller mill. Vertical roller mill, as a kind of high-efficiency energy-saving environment protection equipment, is more and more popular with more customers and has gradually replaced traditional ball mill.

vertical roller mill, cement vertical mill, CHAENGStudy proves that high quality mill and correct operation is key to prolong the service lifespan of vertical roller mill, also to increase its grinding efficiency. So, how to prolong its service lifespan?

Firstly, material hardness and content is important.

Different materials with different hardness and contents will cause different abrasions of grinding roller, grinding table, and liners, therefore, appropriate selection of material can effectively increase the service lifespan of vertical roller mill.

Second, material feeding status is also important.

Feeding evenly is an important factor to guarantee normal operation of vertical roller mill, if there is no configuration of feeding equipment for slag production line, there will be plugging material. Uneven feeding will press much pressure on grinding roller, and cause abrasion directly, thus reducing service lifespan of mill.

Finally, it is technicians’ correct operation and maintenance.

Generally speaking, if the worker do not know about the machine, it is difficult to operate and maintain it, and this will cause the low production efficiency. Therefore, there must be professional and technical personnel to operate it, to perform correct sequence. When starting it, he should first start the blower, then start the main machine.

Methods to Reduce Vertical Mill Power Consumption on GGBFS Production Line

Le 28 avril 2018, 09:15 dans Humeurs 0

 

Vertical roller mill is a kind of machine used in slag production line which can be regards as an energy saving machine. The maximum load of the vertical mill system mainly comes from the main motor and the circulating air blower, which approximately takes up 70% power consumption. So, the key of system power saving is reducing consumption of main motor and circulating fan.

1.Selection of optimum parameters for the system energy consumption of vertical mill

There is no obvious differences of slag vertical mill in working principles, but different process condition, material, operating parameters and methods. So, the operators must observe and analysis the system trending and changing chart on various important parameters such as differential pressure, material-layer thickness, milling pressure, temperature, vibration value, wind consumption, etc.

2.Reasonable usage and control of system air quantity

The power of circulating fan takes up about 35% of total system power consumption, reducing the air can effectively reduce the fan power consumption. If wrong operation and the system can be controlled by the high speed, the production quality only can be held by increase separator speed. However, in spite of stable running it keeps, the currency of circulating air blower and separator is too high, so as to increase power consumption.

In additional, if wind leaking in the system, which affecting the normal wind supply, it will turn up circulating fan valves. Eventually it will increase the fan loadings and power consumption, affecting mill capacity somehow.

3.The adjusting of gear rings

According to the operating conditions, the status of mill plates, rollers and liners must be regularly inspected. Adjusting on time the height of gear ring in case of milling reduction, caused by the thickness of material layers, which can be further results motor loading and currency increasing.In the meantime, do not ignore the abrasion condition of scraper and the distance to the mill floor, which still can influents system consumption.

4.Increasing capacity and equipment operating rate

Powder mill yields the best performance in the maximum stable capacity. Increasing output is not the simply pursuit of high capacity, but maximize the performance of device in the possible range.

As the operators working in frontline on slag production line, it is not only needed to know the new technology and trends, but also master power saving methods and managements, as a result of clear thoughts and direction in managements, and success in energy saving field.

CHAENG Ball Mill Technology and Working Process Analysis

Le 26 avril 2018, 05:55 dans Humeurs 0

CHAENG Machinery is a manufacturer of cement production equipment in China. The cement production equipment of the company is in the leading position in terms of technical process, product performance and quality. The following product advantages of CHAENG ball mill are analyzed:

The screening of CHAENG ball mill adopts a new screening device. The power of this device not only derives from the power generated during grinding of the material in the ball mill, but also uses the weight of the material itself. The screening capacity and efficiency have been significantly improved. . The new screening device used by CHAENG Ball Mill has a large screen area and strong ventilation capability. It will not be blocked during normal operation. The grinding process of CHAENG ball mill has certain leading performance in terms of other manufacturers. The first is the material of the grinding ball. CHAENG uses a high-hardness, high-hardness steel that has been forged on the grinding ball. Under the same weight conditions, the life and grinding effect of the grinding ball is better.

Reduce the customer's investment costs. At the same time, the grinding cylinder is divided into a coarse grinding bin and a fine grinding bin, which increases the grinding quality of the material, but the grinding time does not increase. Customers who require a higher abrasive particle size eliminate the need for a secondary grinding process. CHAENGhas always adhered to the scientific and technical reference, based on the customer's demand as the yardstick of production standards, and constantly innovated and improved the product to create more economic benefits for customers.
