1. Overview of Vertical Roller Mill
The
vertical roller mill is a new type of high-efficiency grinding equipment integrating grinding, grading, conveying, secondary powder selection and finished product packaging, which is widely used in the grinding of non-flammable and non-explosive materials with Mohs hardness below 7, such as quartz, feldspar, calcite, talcum, barite, fluorite, iron ore, coal, slag, cement clinker and so on. Different from traditional ball mills, the vertical roller mill adopts a vertical structure design, which has the characteristics of compact layout, small floor space and low energy consumption, and has become the preferred equipment for modern mining grinding projects.
As a professional mining crushing and grinding equipment manufacturer, Mascot’s vertical roller mill is developed on the basis of absorbing advanced international technology and combining years of R&D and production experience. It has passed the ISO 9001:2008 quality certification, with reliable quality and perfect after-sales service, and is exported to many countries and regions around the world. The equipment covers a variety of specifications, with a processing capacity of 5-120 t/h, a feed size of 0-35 mm, and a finished product fineness of 0.613-0.033 mm, which can meet the diverse needs of different industries and projects.
2. Core Advantages of Vertical Roller Mill
Compared with traditional grinding equipment such as ball mills, the vertical roller mill has obvious advantages in efficiency, energy saving, environmental protection and other aspects, which is the key reason for its wide application in the mining industry. The specific advantages are as follows:
2.1 High Grinding Efficiency and Energy Saving
The vertical roller mill adopts the working principle of roller pressing and grinding, which directly crushes and grinds materials through the pressure between the grinding roller and the grinding disc, avoiding the energy loss caused by the impact and friction of traditional ball mills. It can save 20-30% of power consumption compared with ball mills, and the first law efficiency can reach more than 60%, which greatly reduces the operation cost of enterprises. At the same time, the equipment has strong drying capacity, which can directly dry and grind raw materials with a moisture content of up to 15%, saving the cost of additional drying equipment.
2.2 High Quality of Finished Products
The vertical roller mill is equipped with a high-efficiency classifier, which can accurately control the fineness of finished products. The fineness D97 of the finished powder can reach 3000 meshes, and the content of 2 μm can reach up to 60%. The finished product has the characteristics of high whiteness, narrow particle size distribution and good particle sphericity, which can meet the high-standard requirements of different industries for powder quality, such as the production of fillers and coating calcium carbonate in large paper mills, and the processing of ultra-fine powders in chemical industry.
2.3 Environmental Protection and Low Noise
Mascot’s vertical roller mill adopts a fully sealed structure design, and the whole machine works under negative pressure, which effectively prevents dust leakage and meets the environmental protection emission standards. At the same time, the equipment uses special wearable alloy materials for key parts such as grinding rollers and grinding discs, which reduces the friction noise during operation. In addition, the transmission system adopts a planetary gear reducer, which further reduces the operation noise, creating a comfortable working environment for the operator.
2.4 Easy Operation and Low Maintenance Cost
The vertical roller mill is equipped with an advanced PLC automatic control system, which can realize automatic feeding, grinding, grading and discharging, reducing manual operation intensity and improving production efficiency. The grinding roller sleeve of the equipment can be reversed for use, which doubles the service life, and the wearing parts are easy to replace, reducing the maintenance cost and downtime. Mascot also provides free spare parts and professional technical support, further reducing the user’s later use cost.
3. Practical Application Case of Vertical Roller Mill (Mascot Project)
To better illustrate the application effect of the vertical roller mill, we take a cement plant project in Iran cooperating with Mascot as an example, which fully reflects the advantages of Mascot’s vertical roller mill in practical operation.
Project Background: The customer is a large cement manufacturer in Iran, mainly engaged in the production of cement clinker and cement products. The original grinding equipment of the plant has low efficiency, high energy consumption and poor finished product quality, which cannot meet the increasing production demand. After comparing multiple manufacturers, the customer finally chose Mascot’s vertical roller mill to replace the original equipment.
Equipment Configuration: According to the customer’s production demand, Mascot provided 2 sets of vertical roller mills with a model of LM31-3M, with a designed processing capacity of 40-65 t/h, a feed size of less than 45 mm, and a finished product fineness of R0.08=10-20% (80-90% passing through 200 meshes).
Application Effect: After the equipment is put into operation, the production efficiency of the cement plant has been significantly improved, the daily output has increased by 35% compared with the original equipment, and the power consumption per ton of raw materials has been reduced by 22 kWh, saving a lot of energy costs for the customer. At the same time, the fineness of the finished cement powder is uniform, the particle size distribution is narrow, and the product quality has been greatly improved, which has enhanced the market competitiveness of the customer’s products. After one year of operation, the equipment has a stable operation performance, the failure rate is less than 2%, and the customer’s satisfaction is as high as 98%.
This case fully proves that Mascot’s vertical roller mill has reliable performance, high efficiency and energy saving, and can effectively solve the pain points of low efficiency and high energy consumption in the grinding process of enterprises, bringing considerable economic benefits to customers.
