Analysis of grindable materials in Raymond roller mill

What kinds of materials can be grinded by Raymond roller mill? What are the specific requirements?

 

Analysis of grindable materials

As a professional stone grinder, its grinding objects are naturally all kinds of ores, such as phosphate ore, lime, calcite, barite, limestone, gypsum, bentonite, talc, potassium feldspar, dolomite, activated carbon, marble, quartz, glass, kaolin, cement, construction waste, thermal insulation materials, etc.

 

 

Material case analysis

Case 1: limestone powder is mainly used in power plant desulfurization, concrete mixing station and chemical industry and other industrial raw materials. Raymond roller mill can grind limestone into different powder specifications of 30-425 mesh according to the actual application. The common fineness of lime powder includes 200 mesh, 325 mesh and 800 mesh, of which 325 mesh is the most widely used and the largest consumption.

 

Case 2: construction waste recycling, construction waste and ore are different. It is a mixed material, and its convenient properties are difficult to control, such as hardness, humidity, whether there are impurities, etc. under the current environmental protection cry and the global call for ecological environment construction, the recycling of construction waste and industrial waste can make resources available on the premise of solving environmental pollution problems Efficient utilization can be described as killing two birds with one stone. Construction waste can be reused in concrete materials after being treated by jaw crusher, industrial mill and sand making machine. At present, construction waste recycling and reprocessing technology is constantly explored and innovated. At the same time, the production process and product quality of grinding equipment are required to be improved. High pressure roller mill and European mill newly developed and produced are commonly used They are all upgraded products of Raymond roller mill machine. The fineness of finished products is uniform and meticulous, and the output is large and the efficiency is high. It is suitable for the construction waste treatment.

 

 

Analysis of material performance requirements

Although Raymond roller mill is a stone powder grinding device, it also has clear requirements for raw materials, such as raw material particle size, material hardness, humidity, etc.

 

1. The particle size of material and the size of the feed inlet of the mill are different. The maximum feed size range of 3R to 6R Raymond roller mills is between 15mm and 35mm. If the maximum feeding requirement is exceeded, it needs to be treated by jaw crusher and other crushing devices.

 

2. Material hardness, in addition to ultra-fine powder grinding, most ore mills can grind all kinds of non flammable and explosive ores with Mohs hardness below 9.3.

 

3. Material humidity, material screening and transportation of grinding equipment depend on wind power. If the humidity is too high, it is not easy to grind ingredients and powder screening and transportation. The mill has strict requirements on humidity, and the moisture content of general materials should be kept below 6%.
