• Name :LUM Ultrafine Vertical Roller Mill
  • Description:

    LUM ultrafine vertical roller mill is set ultrafine, grading, and conveying with a suit. It is widely used in chemical industry, metallurgy, non-metallic mineral industries. And it is suitable for grinding the materials that Mohs hardness is below level 5, density is below 3.2, and the compressive strength is below 150Mpa, Such as limestone, calcite, barite, talc, dolomite and other nonmetal ore. The feed size is better less than 10mm. The production is 5-18T/H.

  • Main Structure:

    LUM ultrafine vertical roller mill mainly includes the host, reducer, analyzer, fan, power collector, electric control cabinet and so on. The auxiliary consists of the jaw crusher, bucket elevator, electromagnetic vibrating feeder, and storage bin.

  • How to properly operate the vertical roller mill

    1 stable material bed

    The key legislation is stable functioning vertical roller mill material bed, by adjusting the thickness of the material layer height of dam to adjust the thickness of the correspondence between the right and between them and the mill output, the final product will have a direct impact size . Material layer is too thick will affect the grinding efficiency and product size material, the material layer is too thin and can cause excessive grinding machine vibration. The thickness of the material layer can be adjusted according to the wind speed inside the vertical roller mill, the wind speed increase wear, increase the internal circulation of material layer thickness, to reduce wind speed, reducing the inner loop, the material layer thinning.

    2 vertical roller mill milling pressure control

    Pressure grinding mill output will control, power mill grinding efficiency and have a direct impact, the World State LUM series vertical roller mill works by milling process of implementation material layer, grinding pressure depends on the material properties, particle size as well as the volume of feed. Adjusting the fineness of the material on the best way is to find the right time trial production of grinding pressure and wind pressure can form a reasonable good internal circulation, to ensure stable and efficient milling efficiency.

    3 to guarantee a certain temperature the vertical roller mill

    ZENITH LUM series vertical roller mill is a set of crushing, grinding, grading, milling and drying in one system, the mill drying air temperature is a measure of whether the normal operation of the integrated indicators. The material currently on the market size and the drying effect is very high, in order to ensure that the finished material is less than 0.5% moisture content, the general control of the vertical roller mill outlet temperature of about 90 ~ C. The grinding of the air temperature is too high will affect cleaning effect, the air temperature is too low will affect the mill separator efficiency, air temperature and wind speed to do for a reasonable adjustment.

    4 controls a reasonable wind speed

    vertical roller mill recycle stream to be generated by wind reasonable size classification of materials have an effect, reasonable wind can form a good internal circulation, so that the material layer on the disc proper, stable, high grinding efficiency. It's the wind speed and air volume size has a direct relationship with the volume of feed air volume is proportional to the volume of feed. Quantitative premise for the next feeding, it can be adjusted by the amount of wind turbine valves. We recommend that companies know more about it a number of technical parameters, wind speed and stable production to ensure stable material bed.

  • The automatic control system can realize remote operation, and the operation is simple.
  • The grinding roller and the grinding disc can't contact, and the grinding roller and the lining board are made of high quality material, to less abrasion and long service life.
  • Maintenance is quick and convenient. The operation can realize in the outside of the machine body, reducing downtime.
  • The quality of products is high, and in the same fineness grade condition, it can save 30%~50% of energy, and has good economic benefit.
  • The system is working in confined pressure conditions. It can reduce dust to escape, reduce noise, clean environment, and full compliance with the relevant provisions of the state.
  • The main machine adopts frequency control. It is more energy saving than electromagnetic adjustable speed, and high crushing efficiency.
  • The design of roller sleeve and liner grinding curve is easier to form a material layer than the ordinary grinder, improving work efficiency.
  • The grinding roller lubrication is using separate lubrication station. It can make the grinding roller bearing to obtain the full lubrication, and can avoid the oil storing too much and leakage phenomenon.

Now many large vertical roller mill machine manufacturers are some of the machine-building technology at home and abroad, based on years of experience and customer demand for the design and development of a new type of grinding equipment, such equipment the original grinding process The steps of the integration, first of all cement raw material or glass and other materials for coarse grinding and then drying the raw material for further processing, and finally then grinding and classification, it is this is an ideal device on, but because the machine production manufacturers of continuous research and development can become a reality.

Vertical roller mill can be applied to different production sectors, and even aluminum or coking time will use to it, it can be as large as the original bulk of material grinding, or the original powdered material further processing, so that the material is further processed to meet the requirements on the production.

Vertical roller mill has its own unique characteristics, one is said above to the grinding step, do not think of these steps seem very simple, shortly before these steps are operated separately, that operated separately increased the industry Production on the difficulty and requires a lot of manpower and material resources, but also led to a lot of waste of raw materials, is not conducive to the sustainable development of our country. While using the machine for the industry long ago environmental requirements are relatively high, most of them need to operate within the plant, but now the mill stand can be placed in the open air of the occasion, do not consider too many natural factors influence, can directly reduce the enterprises in the plant construction cost of inputs.

In order to minimize costs, energy consumption at work the mill stand is small and does not require excessive manpower to operate, as long as the button by far we can complete a series of operations. Manufacturers have also worried that once the mill stand will not cause a lot of wear and tear of its own, will not be in use for some time to be replaced after a machine, in fact, as long as you are operating properly in accordance with established procedures for using the mill regularly for professional opposition mill maintenance personnel to check, you do not worry about these issues, because the work is very stable vertical roller mill, to the greatest extent possible to avoid duplication of grinding, work process of reducing the loss of the machine, to avoid work Opposition during impact mill wall and destruction.

Supply the most current design and technical expertise;Supply parts sales and training service far beyond the initial sale;Your profits with quality parts and expert service.

Working Principle:

1) This crusher uses motor as its power. Through the motor's wheels, the eccentric shaft is driven by the belt and the belt wheel to make the jawstock move by a regulated track.

2)The angle between the toggie plate and jawstock will become large as the up of the jawstock. This will push the moveable jaw plate towards the fixed jaw plate,which can realize the multi-crushing of the materials.

3)The angle between the toggie plate and jawstock will become small as the down of the jawstock. The moveable jaw plate will leave the jaw plate at the presure of the tension rod and spring ,meanwhile ,the final products will be discharged from the dischargeing opening.
