How does a limestone mill grind material?

Limestone is a valuable mineral and utilization resource. It is widely distributed in China and its reserves are also very rich. Similarly, it is also an important raw material in industrial production. Limestone can be used as a building material; it can be used to produce cement; it can be used to produce high-grade paper coating; it can be used as a filler in plastics production. In addition, there are many uses.
The limestone ultrafine mill is a good equipment for grinding in modern production. However, with the continuous development of society, the demand for limestone grinding is increasing and there are strict requirements on fineness and quality. In this regard, some manufacturers have designed limestone superfine mills based on the product characteristics and chemical properties of limestone. Of course, limestone is a kind of mineral material, and it is also suitable for milling in mining mills, so this The mill is designed for the grinding of mineral materials such as limestone.
Limestone has a wide range of uses and contributes to human production and life. For this precious mineral raw material, we have to go through some special treatment before it is used, which is more convenient for us to use. Powdered limestone is convenient for mixing cement or adding ingredients. Therefore, in general industrial production, powdered limestone is used. Therefore, the market for limestone mills is relatively large.
Ordinary mills can also grind limestone mineral materials, but we have to consider a problem. Other mills are damaged quickly after grinding minerals and are not easy to clean. The limestone mill is a comprehensive mill for limestone mineral materials. The considerations are also comprehensive. We can use it with confidence, and don’t worry if the mill can bear the grinding power.
The limestone superfine mill introduced by SBM has many advantages over other milling equipment. The equipment is more efficient and energy-saving than the flow mill, the agitator mill and the ball mill. The wearable parts have a long service life, and the grinding rolls and grinding rings are forged by special materials, so that the utilization degree is greatly improved. Generally, it can last for more than one year. When processing calcium carbonate and calcite, the service life can reach 2-5 years. It has high safety and reliability. Because there are no rolling bearings and no screws in the grinding chamber, there is no problem that the bearing and its seal are vulnerable. There is no problem that the screw is easy to loose and destroy the machine. Environmental protection, cleaning using pulse dust collector to capture dust, using muffler to reduce noise, environmentally friendly, clean features, therefore, we should choose limestone mill to professionally grind limestone mineral materials, I believe that the finished powder quality can also be expected.

The mold material developed by DeZe is no less than 10 varieties and the annual output is about 200 tons. We must know that the US investment casting technology is very high, thanks to its advanced technology, high-quality raw materials and strict and meticulous operating procedures. For example, the molds used by the US investment casting foundry each time are produced by the mold factory. New materials: Investment casting is not processed by mold materials, and the mold materials are recycled to the professional production of mold materials. Due to the high quality and uniformity of the mold material, the dimensional accuracy and surface quality of the investment casting wax mold are ensured. Moreover, the ash content and impurities of the wax are also controlled. Foreign companies usually have professional related technical expertise in the production of investment casting materials. The mold materials produced have good stability, low shrinkage, smooth surface and high strength. Good formability and advantages of different parts. The different properties of the mold materials, the mold materials produced abroad include filled molds and unfilled mold materials, which are divided into mold wax, repair wax, emulsifying wax, gate wax, and sealing wax for sealing wax.
The wax used in precision casting is one of the important factors determining the quality of castings.

The mold materials imported from China are mainly medium temperature mold materials, and the quality of mold materials is due to mold materials. The formulation of the formula, the manufacturer attaches great importance to the study of mold material formulation.

The main reason for the low milling efficiency of Raymond mill


Frequently, customers will report that their raymond mill are getting less and less efficient. So the Raymond mill has a lower and lower rate of powder extraction. There are many reasons for this, but the main reasons are generally The factors of the process and the milling machinery have a great influence on the powder extraction rate of the milling machine.

  1. The humidity of the material polished by the Raymond mill, that is, the moisture contained in the material is large, the material is easy to adhere in the mill, and it is easy to block during the feeding process, resulting in a reduction in milling capacity.
  2. Clean up the Raymond mill, and the number of process equipment for cleaning equipment is not enough (that is, there is no requirement for “three screens, two dozens, one stone, one wash material”), the materials are not clean, and the materials contain large amounts of impurities.
  3. The technical condition of Raymond mill is not good. The technical condition of the mill mainly refers to the part of the grinding roller (the grinding head of the cone mill and the grinding disc of the steel mill). The use time is too long and the grinding teeth are blunt. The grinding effect is greatly reduced. The quality of the tooth profile of the surface of the roller of the roller mill is not up to the requirements, and the inclination or the arrangement of the pitch of the roller is not installed. The misalignment of the grinding roll profile is improper.
    These are the factors in the process and equipment of the milling equipment with lower and lower powder extraction rate. I believe everyone knows it!
