The difference of Raymond Mill
and Hige pressure grinding mill, Suspension Roller Grinding Mill, YGM grinding Mill .
As the saying goes,"There is no harm without comparison." Raymond mill is a commonly used machine for milling equipment. After the improvement, Raymond mill, also called high pressure grinding mill and suspension roller grinding mill, which can grind high hardness materials. Then, What are the advantages and disadvantages of these two kinds of grinding mills on the market ?
From the appearance point of view, compared with the high-pressure grinding mill, the Raymond mill machine basically has no difference between the two. The difference lies in innerstructure is that a high-pressure spring is used between the host of the high-pressure grinding mill and the analyzer. The way the soft connection reduces the vibration of the grinding mill.
From the point of view of production advantages, the high-pressure suspension roller grinding mill is designed with a pressure device of 1500kg-2000kg in the upper part of the plum blossom frame in the main grinding chamber of the high-pressure grinding machine. When the machine is working, under the action of high-pressure spring and centrifugal force The grinding roller is pressed against the grinding ring, and the rolling pressure is 1.2 times higher than that of the Raymond mill
under the same conditions, and the output can be increased by 20%-30%; when the grinding roller and the grinding ring reach a certain wear, the high pressure spring is adjusted. The length maintains a constant rolling pressure between the grinding roller and the grinding ring to ensure stable yield and fineness.
In addition, in the range of processing materials, the high-pressure mill has better applicability than Raymond mill, and expands the materials that can be processed and ground. After modification, the fineness of this type of product can reach about 1000 mesh, and fine The degree can be freely adjusted between 0.613mm and 0.33mm, and the adaptability is stronger. Once again on the wearing parts, the high pressure grinding saves the wearing parts. The advantages of a high-pressure mill using a high-pressure machine can make full use of the grinding ring in addition to increasing the output.
Therefore, whether it is a Raymond mill
or a high-pressure suspension roller mill, the user chooses according to his actual production needs.
High-pressure suspension roller mill performance characteristics
1. Unique design, the output is increased by 20-30% under the same dynamic conditions compared with other mills.
2. The finished product has a wide particle size range and the coarsest particle size can reach 0.95 mm (20 mesh). The fine powder particle size is generally up to 0.033 mm (425 mesh). A small amount of material can be as fine as 0.013 mm (1000 mesh).
3. The dust removal effect fully meets the national dust emission standards.
4. The grinding roller device adopts overlapping multi-stage sealing and has good sealing performance.
High pressure suspension grinding mill is suitable for processing various non-explosive mineral materials with Moh's hardness less than 6 and humidity less than 6%,it is widely used in the field of metallurgy,construction,chemical industry,mining ,highway construction etc,. The granularity of the finished powder size can be adjusted between 50 and 325 meshes (315-45micron).Examples of processing materials include quartz,feldspar,barite,calcite carbonate,limestone,talc,ceramic ,iron ore ,carborundum, bauxite,rock phosphate,coal and other materials,total about 400 kinds of materials.
Big materials are crushed by jaw crusher to required particle sizes ,and carried by bucked elevtor to the storage hopper,and are fed evenly and continuously by vibrating feeder into the main unit for gringing .The grinded powder are carried by the airflow from the blower to the classifier to be classified ,the particles which meet the fitness enter cyclone collector through the pipe,and are seperated and collected there .They are discharged at the discharging vavle to become finished products;the airflow is sucked to the blower by return pipe on the top of cyclone collector.The whole airflow system is sealed circulation,and is criculated under positive and negative pressure.
