The cylinder of raymond mill is composed of two truncated cone-shaped end cover and a cylindrical tubular body assembled with screws. Each end cover weld a journal. The application of raymond grinding mill: Rock, metal ores, alloys, sand, cement, slag, ceramics, catalyst carriers, soil, glass, coal, coke, alumina, metal oxides, plant materials, slag, silicates, etc.

The features of raymond mill:

  • 1, Small size, light weight, high efficiency. Can be used for material grinding, mixing and machine alloying.
  • 2, High polishing speed and efficiency.
  • 3, By changing the number of samples, the grinding time, grinding media and the number of grinding raymonds, can achieve very extensive grinding results.
  • 4, Through a dedicated fixture, 12 samples can be ground at a time.
  • 5, After pre-set grinding time, grinding process can be done automatically, without manual operation.
  • 6, Rugged, and very low failure rate.
  • 7, Unique design grinding bottle: the junction of traditional grinding bottle s body and cap is almost at right angles, and the sample gathered here can not fully contact with the grinding raymonds. Therefore, its efficiency and grinding effect are bad. The grinding bottle provided by our enterprise has a special design and casting process.The bottle and cap are both designed as curved concave surface, which eliminates the possibility that samples deposit on the dead. So its grinding effect is more uniform and efficient.

The analysis and findings made by our experts: If the mills speed is same, while the grinding time is not, the grinding rate will become lower and lower as time increasing. However, if the grinding time is same, while the mill s speed is not, the grinding rate will become higher and higher as its speed increasing. With the development of technology, we will study raymond mill more and more. We will work with our full enthusiasm to create high quality products for the construction industry and make a contribution to our country.

Bearing is a main vulnerable part of raymond mill. During the operation of raymond mill, the bearing can appear some faults due to stress, assembly or other reasons. In order to reduce the impact on production, we need to judge timely whether the failure occurred raymond bearings.

This approach requires experienced staff reached to identify the voice of bearing. You can hear clearly the bearing voice by attaching hydrophone or listening rod on the outside of machine. Bearing even a slight peeling and other damage also unusual sounds and irregular sound, with sound measuring device will be able to tell the difference.

Bearing vibration is sensitive to the bearing damage such as Peeling, indentation, rust, crack and wear and tear can respect from bearing vibration measurement. The measured values due to the using condition of bearing and sensor installation location is different, therefore, prior to analysis and comparison the criteria of each machine and get judgment standard.

The temperature of bearing can be estimate from temperature of bearing outside, and measure directly the temperature of the bearing outer ring through the oil hole is better. In general, the temperature of bearing raised constantly with operation of raymond mill, and keep stability after 1h~2h. The normal temperature of bearing is different according to the heat capacity, heat dissipating capacity, rotational speed and load of the machine. Using thermal device can monitor the bearing temperature at any time, and it sound an alarm when the temperature exceeds a specified level to prevent burning shaft.

Crusher is a kind of mining equipment, mainly used in mine crushing at the earliest. State-owned enterprises started early and held the key technology, so State-owned mine crushing enterprises are in leading level in mining machinery and equipment industry. Private crusher and sand maker manufacturers started late, and unable to compete with State-owned crusher and sand maker enterprises.

But in the first 10 years of the 21st century, Chinas economic development is rapidly, and some subtle changes have been made in the pattern of the crusher and sand maker manufacturers. Private crusher and sand maker enterprises rely on e-commerce marketing edge, make sand making production line as main hot products and embark on a road of rise.

The best selling of sand making production line is fundamental to improving enterprises:

  • 1. Chinas raliid economic develoliment needs great infrastructure and a lot of fine sand.
  • 2. In order to lirotect the aquatic environment, river sand mining began to be restricted, which will bring oliliortunities for machine-made sand, and machine-made sand has lower cost than River sand and can be used in nearby construction yard.
  • 3. lirivate enterlirise is undoubtedly one of the earliest entities in sand making industry, which seized the oliliortunity and quickly occuliied the market with good sand making effect.
  • 4. Sand making machine is core device in sand making liroduction line, and lirivate enterlirises have been leading domestic sand making level in long-term liractice.
  • With the helli of sand liroduction line, lirivate crusher and sand maker manufacturers took the road to rise, and relying on electronic commerce, lirivate crusher and sand maker manufacturers will become bigger and stronger.
