The resistance of concrete carbonation, generally the carbonation depth of concrete structures to represent. The relative carbonation depth is smaller, said anti carbonization ability, limestone mill carbonation coefficient is less than 1, which indicated the effects of limestone on concrete carbonation contribution. 

Of course, in order to facilitate the clear analysis of limestone mill of gain and loss, conversion efficiency parameters can also be unified concept, but it is necessary to make the appropriate instructions, so as to avoid misunderstanding. In the composite technology using the limestone and superplasticizer and other chemical additives or other mineral powder (referred to as the double doped Technology), to use the efficiency parameters of composite effect. This situation often encountered in practical engineering, without the general analysis, however when the efficiency evaluation, to be considered. 

In the current promotion of limestone mill in new technology, the general is the use of limestone mill and cement concrete as reference, efficiency evaluation of limestone mills remain equal work and 28d compressive strength conditions. But for some concrete engineering or special performance requirements of the limestone mill, can not fully considered the work and 28d strength requirements.

Along with our country government to expand domestic demand, continue to implement the plan, promote the rapid development of the domestic large number of industry, building materials, metallurgy and chemical industry is one of the very typical.

And is closely related to the construction of kaolin processing plant market, also benefit, the industry was generally optimistic about the near future, analysts believe that, within the next ten years, kaolin processing plant market prospects are very impressive, and environmental protection and energy saving model kaolin processing plant, new kaolin processing plant and the innovation of science and technology type is the industry incense pastry, highly recognized by the market and each channel's favor.

kaolin processing plant is suitable for crushing different hardness of various minerals and rocks, such as high hardness materials, iron ore, non-ferrous metal ore, carborundum, bauxite, quartz sand, perlite, Zong Gangyu, Xuan Wuyan and other finely homework. The main application areas including mines, coal, waste and construction waste recycling, earthwork, city infrastructure, road or construction sites and other field operations.

As the stone reserves of power, China is rich in stone resources, stone resources, has proven reserves of up to 1 trillion tons, ranking third in the world, the stone output in 2008 was 27. 16 tons, accounting for 39 of the total output of stone in the world. 4%, is the world's largest stone producing countries. So far, our main energy or marble processing.

Opencast marble processing are distributed in the provinces of China, characteristics of opencast marble processing is abundant reserves, marble processing near surface distance, so can the earth separation orebody surface, direct mining stone from top to bottom, compared with the underground marble processing has many obvious advantages: Mining easy, convenient use of large mining machinery high efficiency, high production efficiency, and the production cost can be reduced by more than 50%. Due to the above reasons, to improve marble processing capacity and the level of technology and equipment, to promote the development and utilization of stone resources is of great significance in our reasonable and efficient.

In the use process, if too large in the demolition of the old winding when the strength, will lead to steal the trough appear a certain skew or is completely open, in view of this situation generally using pointed nose pliers first tools to repair raymond mill, so that the gear worse the full amount reduction.

In addition, if equipment such as damp phenomenon is also very easy to make the surface of the iron core of Raymond mill corrosion. This time need to use sandpaper grinding series, until it completely clean after coated with insulating paint.

In the process of production, around the grounding and may have a high fever, and then make the core appears burned bad phenomenon, this method is generally taken by chisel to deposition were fully removed, until after a clean and then coated with insulating paint drying process. Many people only care about the price of Raymond mill problems after the fact, as long as the purchase of raymond mill, in the use process, failure may occur and the various problem, when the need for timely maintenance. Raymond mill common fault and basic maintenance methods believe that everyone is familiar with, in use process must pay attention to these points, do a good job of equipment use and maintenance work, so as to ensure the longest service life.

Flue gas from coal combustion in after the collected down fine ash fly ash. hammer mill is the use of the principle of the vibration motor excitation, the material as the transport type jump motion on the screen. The device is applicable to 0.74-10mm, water content less than 7%, non sticky materials of any dry material screening, can be used as the ash with hammer mill to special processing of fly ash, in order to achieve the effect of repeated recycling resources. 

The hammer mill is mainly used for abrasive abrasive materials, chemical, mining, medicine, metallurgy, building material, food, chemical and other industries in the dry powdery, granular or fine powder materials screening.The fly ash with hammer mill can also be used as mixing vibration sieve used for the processing of asphalt in road construction etc.. 

In the production process, the material from the feeder evenly into the charging sifter mouth, sieve, produced a number of specifications through multi-layer screen material, respectively, from the respective outlet. In the fly ash in the processing process, because the fly ash particle size smaller and better mobility, so the screening effect is better, the fly ash into the vibration screen center, trajectory flow on the screen to bounce up and down and in accordance with the hammer phase angle is produced, coarse powder and fine powder is automatically separated and rotated to the discharge port.

All these require the use of kaolin grinding production line, of gold points for processing high schedule, to ensure the good application effect. Three dimensional kaolin grinding production line is a lot of equipment Changsha kaolin grinding production line of excellent performance, also known as rotary kaolin grinding production line, the excitation motor assembly has an eccentric weight, motor rotary motion into horizontal, vertical, inclined three dimensional motion, then this movement and transferred to the screen surface so as to realize the material screening.
