Application value of vertical mill and ultrafine vertical mill in nonmetallic mineral powder making area

In recent years, vertical mill has become to be high efficiency and high accuracy classifying powder grinding equipment, also the mainstream equipment in coal, cement, slag, non-metallic minerals, and desulfurization in thermal power plant. Vertical grinding and ultra-fine grinding mill has gradually become a breakthrough in the traditional milling machine with its advanced grinding technology to solve the problem of low efficiency, high energy consumption, high cost of high-quality milling important equipment, in the non-metallic powder making area.ee

As a high-tech enterprise with R&D and manufacturing of milling equipment, Guilin HCM Machinery has accumulated a large number of advanced application technology and rich experience in R&D and production, and has reached the deep road of integration with all major scientific research institutes. And the introduction of advanced production technology continue to consolidate the milling machine powder process, creating a lot of success such as the classic non-metallic mineral powder production line case, through continuous research, summary, innovation, upgrade, Guilin HCM Machinery produced HLM vertical grinding machine is an integration of drying, grinding, classifying, transportation equipment, and preferred equipment for its high efficiency, low power consumption, the equipment process is simple, small footprint, low noise and many other advantages, the production of HLMX ultra-fine grinding equipment with excellent technical advantages to break through the traditional milling machine large-scale fine processing bottlenecks, in order to enhance the level of development and utilization of non-metallic mineral to promote the non-mining industry sustained and healthy development.

The technical advantages of vertical mill

With the development of grinding machine and manufacturing level, vertical grinding production technology has also been greatly improved, compared to the traditional mill, vertical mill is widely used in limestone power plant, desulfurization production line, slag and other industrial solid waste production line, coal mine production line and other production areas of advanced equipment, according to the difference of raw materials, vertical mill can be divided into cement vertical mill, slag vertical mill, coal mill, steel slag vertical mill, tailings vertical mill and other equipment, has significant advantages and a wide range of practical significance for the efficient realization of all kinds of large-scale production of materials.

1. Efficient, energy saving, environmental protection: vertical mill has large production capacity per unit comparing to ball mill, grinding efficiency has been greatly improved, and energy consumption is 40-50% lower. Vertical mill system is full negative pressure operation, the overall operation is small vibration, low noise, and the system is in a sealed state, basically dust-free.

2. Comprehensive investment cost is low: the whole vertical grinding process is very simple, the structure is relatively compact, covers an area of only 50% of the ball mill, more ideally, the equipment can be open-air layout, greatly reducing the investment and the cost of building.

3. Drying ability, strong adaptability to the material: vertical mill with hot air conveying materials, to control the inlet temperature, when grinding large moisture material so that the product reaches the required final moisture. Based on this principle, vertical mill can process material moisture reaches up to 15%, effectively breaking the traditional mill bottlenecks of unable to grind high hardness, high moisture, high fineness material, become preferred equipment for quartz sand, steel slag, slag, pyrophyllite, iron ore, lignite, cement clinker and other materials.

4. Less wear-resistant parts, longer life: grinding roller, plate liner are made with special materials, roller can be turn out of the machine by hydraulic device, bigger space for replace the roller liner and repair mill, extend the life of wear-resistant materials, improve the entire equipment performance.

5. Good explosion-proof performance, high reliability: vertical mill apply with a new roller sealing device, greatly improving the sealing performance, no need to seal the blower to reduce the oxygen content of the mill, thereby improving the whole explosion suppression performance.
