LUM Ultrafine Vertical Roller Mill

LUM Ultrafine Vertical Roller Mill

LUM Ultrafine Vertical Roller Mill is suitable for metallurgy, building materials, refractory materials, low hardness material crushing. LUM Ultrafine Vertical Roller Mill grinding structure is different from other Ultrafine grinding mill, mainly composed of a roller, roller wheel and support bearing components, compressing and regulating device and a driving device etc.. Vertical Roller Mill grain size regulation method is wedge or gasket adjusting device is arranged between the two roller, top wedge device with adjusting bolt, when the adjustment bolt will wedge block upward pull up, wedge will activities roller top from fixed wheel.

LUM Ultrafine Vertical Roller Mill Advantages:small fine aggregate crushing, high efficiency, power consumption is much less than other mill. Before installing the equipment should make a comprehensive inspection to deal with vertical superfine grinding Mill, in order to ensure the correct. Vertical Roller Mill general installation with cooling machine, located at the bottom in the cooler , and also can be installed separately according to the space condition.

In order to ensure the LUM Ultrafine Vertical Roller Mill normal work,must comply with the following conditions

  • Material with a diameter of two roller clearance ratio shall not be greater than 4:15.
  • the roller diameter and focal block diameter ratio shall not be less than 20:1. If the violation of these conditions, block material cannot broken into between two rollers .

How LUM Ultrafine Vertical Roller Mill Progressing Ore

before smelting Ore, in order to ensure the smooth progress of the smelting process, need to cut large pieces of ore crushing, and then size fractionated, then according to a certain size requirements of the different size grades of ore batch addition of iron smelting furnace. The ore is belongs to the scope of brittle material, according to material mechanics towel elastic deformation theory, ore under the action of external force, when the stress reaches the strength of the material limit, the ore is broken.

LUM Ultrafine Vertical Roller Mill Production Line

In the stone production line , the equipment used is relatively large vertical roller mill , including for stone crushing jaw crusher, secondary crusher crushing counterattack , or use a heavy-duty molded stone crusher . Sometimes you need to configure impact vertical roller mill according to process requirements . Where , in the stone production line , most of the maintenance work is for the maintenance of the equipment vertical roller mill to do the work in this part of the maintenance of stone production line will enable successful completion . We will three aspects vertical roller mill maintenance.

1. vertical roller mill bearing maintenance

Bearing parts of the crusher is the most likely broken , worn in the use of relatively large so they need regular maintenance , frequent refueling to increase bearing life.

2. vertical roller mill maintenance routine aspects

To ensure the vertical roller mill in good technical condition , ready to be put into operation, reduce downtime , improve crusher good rates , utilization, reducing crusher wear and extend the life of the crusher ; do regular maintenance , enforced correctly processing using relational maintenance and repair , only not allowed to raise or just repair support .

3. vertical roller mill lubrication maintenance

Constant attention and timely manner lubrication friction surface , can guarantee the life of jaw crusher normal operation and extend equipment . Join the bearing grease is 50-70% of the volume must be replaced every three months , the application of clean gasoline or kerosene carefully cleaning roller bearings runway oil change . When the toggle plate and toggle plate pad contact must inject grease before starting crusher

Blast furnace slag and slag is a by-product of blast furnace ironmaking, resulting in the cement industry, also called powder. As one of the main water slag mixture of cement production, has a long applied history. The mining process must be applied to vertical roller mill, specifically how to use energy-saving environmental vertical roller mill, let us try to understand the process of. Water slag as building material for the production of cement and concrete, because the water slag with hydraulic cementitious performance potential, in cement clinker, lime, gypsum and activator function, which can be used as high quality raw material for cement, cement production process is the traditional cement clinker and some hybrid materials (including water slag) together with vertical roller mill in crushing, and then into the ball mill grinding. Because the water slag has a certain strength, so the mixed material blending water residue will make the later stage strength of cement is warranted. But the water slag grindability is poor, this process not only increases the energy consumption of the vertical roller mill, also is the most important characteristic not really play water slag. Zenith machine introduced energy-saving environmental vertical roller mill production water slag, superior performance, more energy saving and environmental protection. After the water slag slag vertical roller mill can meet international standards, cement, concrete production of raw material of high quality. Vertical roller mill according to the conditioning tower and dust collector position to improve energy saving and environmental protection requirements, the vertical roller mill has arranged two schemes, namely three fan vertical roller mill system and double fan vertical roller mill system. The cyclone dust collector for collecting product. This arrangement can reduce the vertical roller mill system working pressure and the amount of gas collector. Used esp can also use the bag dust collector as the dust removal equipment; the dust collecting device can be electric precipitator and bag dust collector. Technology production and application method of tripod machine vertical roller mill processing water slag is the diagenetic agent alone can produce multicomponent synergy function, balance and coordination of the vertical roller mill shortcomings of mixed wood higher proportion occur due to machine is used in cement production, reduce clinker, increasing of mixture material ratio to achieve high quality requirements in the range of technical requirements, so as to improve the cement production, reduce production costs, reduce energy consumption. Zenith machine vertical roller mill, low energy consumption, the vertical roller mill system power consumption 20% lower than the ball mill, and increased with the moisture of the raw material, energy saving effect is more obvious.
