New Technology of Ceramic Raw Material Vertical Mill


Release date: 2023-05-27 10:37:33

At present, the grinding equipment in ceramic industry is mainly ball mill. The ball mill is the earliest and most commonly used grinding equipment. The biggest disadvantage of the ball mill is that it has less useful work and low efficiency. Generally speaking, improving the mechanical performance of the ball mill from the aspect of mechanical structure has almost reached the limit of technology. Ceramic raw material vertical mill, as a new type of ceramic raw material grinding equipment, plays an important role in energy saving and productivity improvement of ceramic raw material grinding. Next, HCMilling(Guilin Hongcheng) ceramic raw material vertical mill manufacturer will introduce you to the new technology of ceramic raw material grinding.

There are many types of ceramic raw materials, and the moisture content is different. In order to ensure the consistency of the formula before and after the raw material grinding, Chinese ceramic enterprises have always adopted the backward open-flow ball milling process. The biggest advantage of this ball milling process is that it can ensure that the proportion of ceramic raw materials does not change before and after ball milling, and the materials are mixed very evenly. The gap ball mill also plays a role in mixing materials evenly while grinding the materials. However, the biggest disadvantage of this ball milling process is that the "over-crushing" phenomenon will inevitably occur during the grinding process. The so-called "over-grinding" means that the materials that have reached the fineness requirements are not discharged in time, and the ball milling is still continued in the machine. The coarse particles are not easy to be directly crushed, and as a result, the production capacity of the pulverizer is reduced and the unit power consumption is increased. Therefore, the phenomenon of "over crushing" should be avoided as much as possible.

 

New ceramic raw material grinding process The new technology adopts the two-stage grinding process of "vertical pre-grinding" and "ball mill", which effectively avoids the large amount of energy consumed by the material in the initial crushing stage of the ball mill and reduces the cost of the ball mill. At the same time, it can greatly shorten the time spent on the entire ball milling process of materials, thus achieving energy saving in the raw material preparation stage. The so-called vertical pre-grinding is actually a reform of the vertical mill, which adds a combing device and a screening device inside the mill, and cancels the winnowing system. The powder is discharged from the lower part of the mill, and hot air can be ventilated inside the mill. Drying, which solves the problem that the raw material has high moisture content and cannot be ground.

 

The grinding principle of vertical pre-grinding belongs to "material bed grinding", or "material bed extrusion grinding". The advantages of material bed extrusion grinding are more useful work, high mechanical efficiency and less wear. The joint application of vertical pre-grinding and ball mill in the grinding of ceramic raw materials is a kind of ceramic raw material processing for the ceramic raw materials (sand and mud) commonly used in ceramic enterprises at present with the processing technology of "traditional single ball mill". Innovation in craftsmanship. The sand and gravel are ground by vertical pre-grinding, and then screened. The qualified powder is sent to the ball mill for grinding, and the unqualified powder is returned to the vertical pre-grinding mill for regrinding. At the same time, the mud is crushed, pulped, separated, ground, and then enters the slurry tank.

 

Ceramic raw material vertical mill is a new high-efficiency and energy-saving ceramic raw material grinding process. It solves the problem of huge energy consumption in the traditional ceramic production process, reduces the energy consumption of ceramic raw material grinding, and improves the production efficiency of ceramic production. The development of the ceramic industry is of great significance. Its main advantages are as follows:

 

(1) Since there is no direct contact between the grinding roller and the grinding disc during the vertical pre-grinding operation, the wear is small, and the finished material meets the requirements of the ceramic production process.

 

(2) The new process adopts: the vertical pre-grinding is the raw material with a particle size of ≤50mm, and the vertical pre-grinding grinds the raw material to a particle size of ≤150 mesh, and then sends it to a ball mill for grinding, which can save energy by about 25-40%.

 

(3) Created a precedent for the intelligent control of the ceramic raw material processing process: for the ceramic raw material grinding process, a centralized industrial controller is used on the main equipment to precisely control the processing parameters of the ceramic raw material, which can realize the ceramic raw material grinding process automation control.

 

(4) With the new ball milling process, raw materials with a particle size of ≤150-200 mesh (adjustable) are fed into the ball mill, and the particle size of the raw materials is relatively uniform. In order to further improve the efficiency of grinding raw materials, shorten the ball milling time and reduce the wear of ball stones.
