Raymond Lei factors also control the granularity adjustment, what does? 1, the spacer ring diameter factor, high pressure mill, the retainer ring to the diameter of the particles in the crushing chamber residence time, every ring diameter larger particles shorter residence time, crushing the middle Lu greater granularity, the higher the yield , whereas lower myself. 2, air volume factor: You can control the air flow through the valve regulating the outlet end Raymond. Zhengzhou Lei Machinery Co., Ltd. is a professional manufacturer Raymond manufacturers, a question about the Raymond mill can contact our customer service, milling machine manufacturers, we will be the first time for you to answer Raymond mill can process greater hardness of the material recently several users asked us some questions, their material is quartz, milling machines, small series to introduce over the material Mohs hardness of stone, quartz Mohs hardness of 7, be relatively hard material, the user consult us whether this process, we give an affirmative answer. But there are deficiencies, is wearing parts wear more serious, a relatively short time replace indirect. Used or understood the Raymond mill users are aware, for the same equipment, different hardness of the material of finished product are not the same. The yield is relatively low hardness higher than the hardness of the finished material is several times higher. The other is the high hardness of the material wear and tear on Raymond is relatively large, accessories and more damage will increase the user's cost of production. So when the user selects, be sure to ask Raymond manufacturers, Lei according to your needs for you to choose the most suitable for your device. Lei mill contribute to the development of mining machinery, according to statistics, is now the development of the domestic mining machinery industry, industry technology development trend and the trend, especially mills, crushers and other equipment cutting-edge technology, contribute to the development of mining equipment and improve. Mining machinery industry as a pillar industry State of the economy, it plays an important role in China's economic construction and social development. In mining, energy, transportation, and industrial raw materials for other industries, mining machinery, mining equipment and as a construction material processing equipment, which aims to provide a steady stream of a large number of basic industrial goods and energy, great protection of the national economy healthy and rapid development. Therefore mining machinery manufacturing industry a national basis to establish an independent industrial system, but also to measure an important symbol of national industrial strength. Broken equipment mining machinery inside the mill is an important part, including jaw crusher, impact crusher and other crushing equipment and Raymond mill, high pressure hanging roller mill, high pressure micro powder mill and several Ten equipment, not only played a significant role in minerals, coal, electricity, chemicals, building materials, refractories, metallurgy, water conservancy, highway construction and other sectors of the deep processing of raw materials, but also for railways, roads, water and electricity, municipal engineering, etc. Construction provide a highly efficient and reliable technical equipment support.
