Raymond Mill

The Raymond mill was ever popular in mining, building materials, chemical engineering and metallurgy industries for size reduction, dispersion, or specialized needs, powder generation and processing for industrial process. Now MTM series grinding mill has better performance than it.Over the years, the master of ultra-fine powder processing technology equipment, people on these issues thorough technological innovation. In the use of traditional Raymond machine, we found that in the processing of calcite Raymond class ore, 325 heads of 10um slag contains large amounts of ultra-fine mineral powder, if you can isolate and expand production, will greatly improve efficiency. For this reason a large number of structures for Raymond renovation:

Host the traditional way has been improved, the spindle and plum frame were conducive to the stability of structural transformation, keep it running smoothly.

Center no swing. The traditional part of the analysis machine towed by the cavity, the cavity to drive the rotation of external cavity hanging two isolated, thus increasing the stability of its work, durability. In the crush zone unit causing the material to be milled is always gathered in the grind area for effective processing, improve the grinding efficiency, we are also on the roller structure has been updated so that the grinding roller and grinding rollers can be complementary operation. In the rotation while also revolve. So efficacy and greater durability. And can work under greater grinding force and higher operating speed. In the ventilation section, bellows duct by the original horizontal bottom tilted 30 degrees to the center to form a bucket-shaped, ensuring bellows, air duct is always smooth without clogging, which always maintain the required amount of wind, the host milling at high efficiency. In the design of the entire system, from the traditional two collection to four collection. Twelve were collected by vacuum locked loop style collection, no dust overflow, 34 were collected using a controlled overflow wet and dry series collection, eliminate dust overflow. While collecting the entire system to ultra-fine powder, to prevent or reduce pollution of the surrounding environment.

The new machine using the above Raymond can calcite, dolomite, talc, kaolin, barite, rutile, fluorite and other non-metallic mineral ultrafine grinding. Proven chosen feed size of 25mm calcite grinding, when the fineness was adjusted to 1250 mesh (10um), the output can reach 450kg / h, while the input power need only 23kw. Having significantly more than the traditional Raymond high price.

Vital function of Raymond Mill in national economy

Manufacturing is the main sector of industry. Raymond mill high-end equipment is an important foundation of the development of manufacturing, and also a concentrated reflection of the development of national manufacturing levels. At present, the driving force and the environment of China's raymond mill industrial development are undergoing profound changes, and Chinese industry has entered a critical period when only speeding up transformation and upgrading can promote development.

China's industrial transformation and upgrading should be in accordance with essential requirements of going the new road to industrialization with Chinese characteristics and building a modern industrial system, taking scientific development as the theme, accelerating development transformation as the main line, and independent innovation and reform and opening up as a driving force, promote the deep integration of informatization and industrialization, foster the growth of strategic new emerging industries, transform and upgrade traditional industries and accelerate the development of producer services, fully optimize the technical architecture, organizational structure, layout structure and industrial structure, establish the industrial development on the basis of innovation-driven, intensive and highly efficient, environmentally friendly, benefit the livelihood and endogenous growth, and continually enhance the industry's core competitiveness and sustainable development capacity to lay a more solid foundation for the industrial power construction and building a moderately prosperous society.

Manufacturing industry directly reflects the level of a country's productivity and it is an important factor to differ developing and developed countries. The manufacturing occupies an important share of the national economy of the developed countries, and the mining machinery industry also occupies temporarily indispensable location in the manufacturing sector. The professional mining machinery manufactures should commit to the exploration and study of the raymond milling equipment and make their own contribution to the development of the manufacturing.

Wide Application of Raymond Mill in Gypsum Powder Processing Industry

Gypsum powder is one of the five gel materials and plays an important position in the economy. It is an important industrial raw material which is widely used in many industries such as construction, building material, industrial mold and art model, chemical industry and agriculture, food and medicine and cosmetic field.

Gypsum has long been applied, but in the early stage it is simply used for making chalk, putty, tofu and simple artware, due to the lack of deep research and development, it was not valued by people then. In the late 1970s, especially even since the reform and opening up, with the fast economic development, large quantities of construction industry, building material and other relevant industries have dramatically increasing demands for gypsum and it is more and more valued by people and now the gypsum powder production industry has become a huge emerging industry.

Raymond mill can process gypsum into different specifications, fineness and output and it is especially suitable for the processing and production of gypsum powders. Compared with common powder grinding mills, this equipment has high efficiency, low electricity consumption, small coverage size and one-time investment. The final granularity of Raymond mill produced by SBM Machinery can be arbitrarily adjusted in the range of 80-325 mesh and some materials can reach 2000 mesh so that the gypsum powders can meet the fineness requirement in the market, so that it is ideal gypsum powder processing equipment.

What Should We Pay Attention to in Raymond Mill Maintenance?

1. In the use of Raymond mill, there should be special staff responsible for the supervision, and the operator must have a certain technical level. Before the installation of Raymond mill, it is necessary to train the operators on technique, to make them learn about Raymond mill working principles and performance and familiar with the operation procedures.

2. Lay down equipment maintenance and safe operation rules to ensure the Raymond mill a stable running and a long service life. At the same time, have access to necessary maintenance tools, grease and the corresponding accessories.

3. Raymond mill should be inspected after using a period of time, as well as the easy damaged parts such as the grinding roller, grinding ring and shovel blade, etc., to repair and replace timely. In both the pre-use and post- use of the grinding roller, carefully examine the connecting bolts and nuts to see whether there is any of them are loose or not, and to see if the lubricating oil is enough.

4. Replace the grinding roller for a new one after being used for more than 500 hours, as well as clean every rolling bearing in the grinding roller shell and change the damaged parts timely. The manual pumps and grease gun are available for refueling.

5. Lubricate the bearings with 1-MOS2 lubricating grease or ZN-2 sodium bitter grease.

6. The grinding roller bearing should be refueled every shift, the main engine central bearing every four shifts and the blower bearing once a month. The temperature of bearing room shall not exceed 70 ? Bearing overheating once founded, we should disassemble the bearings and then clean it and the bearing room and other accessories.

The correct usage and maintenance of Raymond mill can effectively improve its service life and work efficiency.
