Limestone Pulverized Coal Power Plant Vertical Grinding Mill 10-90T/H Capacity

10-90 t / h Capacity Slag Coal Clinker Cement Pet Coke Limestone Grinding Vertical Mill
 
Product Introduction

The structure and working principle of the vertical mill are described, and the process configuration, process flow and performance characteristics of the vertical mill are described.

As a kind of grinding equipment, vertical mill has the characteristics of strong grinding force, easy adjustment of product fineness, uniform powder degree, and easy control of chemical composition. In the technological process, it can integrate the functions of grinding, powder sorting and drying, and can form a closed-loop grinding production system, which is especially suitable for the grinding of medium-hard materials. The new vertical mill has been put into use, and has achieved remarkable economic benefits due to energy saving, less pollution and high productivity.

【Applicable Materials】

Grinding raw meal, clinker, granulated blast furnace slag, iron ore, limestone, coal powder, coke powder, coal gangue, fly ash, pozzolan, gypsum, calcite, pyrophyllite, quartz, clay, sandstone , bauxite, silica fume, and other metal ore and non-metal ore processing industry

According to the different physical and chemical characteristics such as moisture, grindability, product fineness and safety of various types of materials in various industries, we have developed highly targeted, mature, reliable, safe and efficient grinding technology and supporting equipment. The core equipment is HVM type.

Vertical mills handle materials ranging from high humidity to dry materials, from extremely difficult to easy-to-grind materials, and the fineness of products ranges from coarse to fine. Provide scientific and reasonable complete process plan and equipment selection of vertical mill pulverizing system, and provide integrated powder processing solutions.

 
Technical DATA

【An Introduction】
HVM vertical mill can process materials with high water content of 20%~30% (such as carbide slag, lignite, etc.) to materials with water content less than 1% (cement clinker, etc.), and has strong adaptability to the moisture content of materials.

【Solution】
For the treatment of high-moisture materials, the drying capacity of the vertical mill is required to be high, and the drying capacity of the vertical mill should be regarded as an important direction for equipment selection. The three capabilities of , drying and powder selection are scientifically and reasonably matched, and under the premise of ensuring that the materials meet the drying requirements, the output of grinding and powder selection is brought into play to the best level, so as to achieve reliable, efficient and energy-saving equipment selection;

For the treatment of low-moisture materials, since the vertical mill is essentially a material bed grinding, when the moisture of the incoming material is too low, it is difficult for the material to form a stable material layer on the grinding disc after entering the vertical mill, which will cause the vertical mill. Abnormal vibration, unable to run stably. In order to ensure the stable operation of the vertical mill, it is necessary to solve the problem of how to stabilize the material layer. Generally, the measures that can be taken include active means (such as controlling and adjusting the thickness of the material layer, grinding pressure, height of the retaining ring, slag discharge, etc.) and passive means (such as adding a water spray device, etc.). At the same time, it is reasonable to take into account the powder selection ability of the vertical mill.
