Vertical Ore Milling Equipment are fine grinding equipment for the fine grinding of hard, medium hard or soft material in the building materials industry. Vertical Ore Milling Equipment has widely applicaiton in the cement industry, ceramic industry, power sector used more, such as cement clinker, limestone, clay , clay, gypsum, feldspar, barite and coal.

Vertical Ore Milling Equipment grinding system

Vertical Ore Milling Equipment has become the first choice for the cement industry, raw material grinding, it is estimated there are more than 600 sets of production. Large Vertical Ore Milling Equipment capacity has reached 600 t/h, the transmission power of 5000KW. In the early 1990s, Cement Vertical Ore Milling Equipment areas has progressed, there are many large Vertical Ore Milling Equipment production. The basic process is the Vertical Ore Milling Equipment finish grinding, but in order to pre-grinding and roller presses to compete, adapt to the pipe grinding system transformation, and since 1987, Japan has developed a Vertical Ore Milling Equipment pre-grinding system, and gradually be developed.

Vertical Ore Milling Equipment grinding system established a process shown in Figure 1-1 airflow 2, where the raw material was isolated by the cyclone, and then into the exhaust fan 3. In the positive side of the ventilator, some air flow to return to the stand in the Vertical Ore Milling Equipment, in order to ensure a certain degree of upward air flow velocity, air flow through the rest of the precipitator 4 into the exhaust 5.

Vertical Ore Milling Equipment Design And Characteristics

Vertical Ore Milling Equipment is the use of 2 to 4 grinding rollers close to the disc, as the speed of rotation of the ground material, is basically a layer of crushed material. The material in the Vertical Ore Milling Equipment is mainly due to the rolling rolls, and because there is a difference between the speed of rotation of the roller and the disc, it also has cut abrasive. Feeding center disc material effect due to the rotation of the disc centrifugal force to move into the disc surrounding the disc between the roller and the roller. Under the action of the roller hydraulic unit and pressing means applying pressure to the material grinding roller inside.

After crushing the material by the rolling action to continue to move the edge of the disc, the disc from the edge of the ring gauge overflow. At the same time, Vertical Ore Milling Equipment speed up the hot air ejected from the nozzle ring surrounding the disc, the coarse crushed material blown back disc again, and materials for the suspension drying. Powder with hot air into the upper separator separates certain qualified powder particle diameter overflow with the air and collected from the upper part of the Vertical Ore Milling Equipment, coarse disc and return together again grinding the feed material.

Vertical Ore Milling Equipment Design And Feature

    Vertical Ore Milling Equipment Design And Feature
  • (First)Vertical Ore Milling Equipment grinding roller and disc must remain on the material layer generates sufficient grinding pressure, so that the material being compacted and crushed. That pressure grinding roll pressure, it grindability materials, water, require production, wind speed and Vertical Ore Milling Equipment type and size and other factors. Grindability and moisture small materials, as well as lower production requirements, the roll pressure can be smaller. Roller pressure depend on the pressure of the hydraulic system pressure device (rod) and the roller weight applied to produce, and can be adjusted during operation.

    In addition, the material layer on the disc must have sufficient stability and to maintain a certain height of the material layer. Shown in Figure 2-1, the first to be compacted bulk material mill rolls, roll pressure to focus on the role of large pieces of particulate material, or when the pressure increases the compressive strength of the roll over of materials, materials Jibei crushed. Materials other larger particles are then continuously rolling so that the particle size is reduced, until the fine particles is extruded disc overflow.

  • (Second)Vertical Ore Milling Equipment grinding efficiency not only with the roll pressure, but also with highly relevant material layer. There are more than enough contact surfaces in contact with the material must be kept between the roller and the disc. And materials to maintain a certain height, so that the material to withstand the constant pressure rollers. For material to form a stable material layer more difficult, must take measures to control.

  • For feed materials such as dry powder or more material on the disc easily flow, the material layer is unstable, so to take some water spray method to stabilize the material layer. Can also be automatically adjusted to accommodate the unstable roll pressure change material layer.

  • Vertical Ore Milling Equipment Grinding cycle
  • (Third)Vertical Ore Milling Equipment is a drying and grinding mill wind swept larger type, the body cavity, allows greater airflow, so that the mill fine particulate material in suspension, so the Vertical Ore Milling Equipment for grinding raw when material or coal, the higher its drying efficiency.

    Vertical Ore Milling Equipment and supporting the use of dry-process cement kilns, can take advantage of the hot exhaust gas discharged from the preheater pass into the mill bake in the material. General mills can stand up to l5% to dry ingredients.

  • (Forth)In the Vertical Ore Milling Equipment and classifier as a whole. When the particles leave the disc edge material particles, is a high-speed air flow blowing collar rise, fine particulate material is brought to the separator, the finer particles are selected, as shown in Figure 2-2 coarse settlement from the gas stream to the disc, there are some places a lower rate of coarse particles into the classification zone, may be pulling away from the rotor blades hit and fell onto the disc. Form a cycle grinding.

Vertical Ore Milling Equipment Workflow
