In 1906, C.V. Grueber founded a machinery factory in the southern suburbs of Berlin. Using his patents obtained in the United States, he produced the first Maxecon mill and used it as the coal grinding equipment for the MOABIT power station. The grinding power can reach 5TPH. In the past few years, nearly 600 units have been sold and used in different industries. In the same period, BEWAG planned to develop a coal mill with a higher output. After E.C. Loesche took over and headed the C.V. Grueber Machinery Plant, he decided to purchase the patented Raymond Centrifugal Ring-roller Mill from the United States to produce the first generation of Raymond Mill system.

However, practices proved that the fineness of finished products produced by Raymond Mills was dissatisfactory. Usually, the fineness was about 400 meshes, with very little materials fineness up to 1000 meshes, which did not meet the requirements of refined development. This kind of Raymond mill was only suitable coal materials with soft, low ash and good grinding property, because the grinding force (centrifugal force) of Raymond coal grinding mill was limited by the diameter and rotation speed of grinding roller at that time. However, German coal was characteristic of hard and high ash content, which required higher grinding power. Therefore, Raymond mill of this structure wasnt prevalent in Germany as itwas difficult to meet the grinding requirements. But it was surprising that this kind of Raymond mill was just suitable for the coal quality in the United States, there was no doubt that Raymond mill was widely promoted and applied in the United States.

In 1925,E.C.Loesche summarized the use characteristics and disadvantages of the first generation of Raymond coal mill and decided to further improve the structure of Raymond mill. He developed a mill whose grinding principle is opposite to the first one, which was called improved Raymond mill.

The ventilation of this improved Raymond mill system has two modes: positive pressure and negative pressure direct blowing. The patent of this type of Raymond mill was soon acquired by Combustion Engineering (a company in America).

The structure of this Raymond mill was similar in many aspects to that of the current Loesche mill. However, it was different from Loesche mill on its cylindrical grinding roller and grinder table with a 15 degree sloping surface. The grinding roller was equipped with a roll-out device for inspection and maintenance. And it also equipped a protective device to prevent metal contact between the grinding roller and the grinding table. In addition, the grinding roller can be lifted in advance before the mill starts that can reduce the pull-in torque.

With the development and improvement over the years, there are more and more types of Raymond mills. Since China introduced this machine, Raymond mill has been well received by majority of users due to its high stability, well-adapted and highly cost-effective. So we can see that Raymond mill plays an important role in grinding equipment.

SBM has launched three upgrade series of Raymond Mills, MB5X Pendulum Roller Mill, MTW European Grinding Mill and MTM Medium-speed Grinding Mill respectively. Compared with the first generation of Raymond Mills, these three types of grinding mills are more energy-efficient and environmentally friendly, have more sophisticated automatic control systems, and can help users to move toward refined and large-scale development.

According to accumulation and experimental analyses of on-site test data for more than thirty years, SBM, a Chinese grinding mill manufacturer, has researched and developed the fifth-generation pendulous hanging grinding mill MB5X grinding mill. All non-combustible and non-explosive brittle mineral products whose Moh's hardness are below Grade 7 and water content below 6% could be ground by this grinding mill.

MTW European Grinding Mill is innovatively designed through deep research on grinding mills and development experience. It absorbs the latest European powder grinding technology and concept, and combines the suggestions of 9158 customers on grinding mills. This grinding mill perfectly satisfies the production demands of the customers on 200-33m (80-425Mesh) fine powder.

MTM Medium-speed Grinding Mill is a world leading tool for powder grinding. MTM grinding mill absorbs world first-class industrial powder milling technology and organizes the technical experts and related engineers for elaborate design, test and improvement.

After jaw crushers break large bulky materials to smaller ones, elevators work to send materials to the hopper. Then, by electromagnetic vibrating feeders, broken materials are evenly and quantitatively sent to the grinding chamber of MTM Medium-speed Grinding Mill. After grinding, materials are blown away by airflow to the powder concentrator for classifying. Under the action of the impeller of powder selector, materials which fail to meet fineness would be sent back to grinding chamber to get another grinding while qualified powders would be collected by cyclone powder collector and discharged from the bottom as finished products. And, after that, the airflow would go into the fan along with the air return duct at the top of cyclone power collector. This system adopts a closed circuit and runs under positive and negative pressure.

Because materials have a certain content of moisture, heat generated during grinding may lead air evaporation or swell in the grinding chamber so that the amount of airflow increases sharply. Besides, if the feed port and joints of pipelines are not sealed well, external air may intrude the grinding mill and lead imbalance of airflow. So, SBM arranges exhaust valves at the air outlet of the fan to induce redundant air into the bag filter. After purifying, the redundant air is discharged. This arrangement can achieve both the balance of airflow and the eco-friendly production.

Correct operation of the Raymond Mill is a must. Improper operation may cause damage to the Raymond Mill and shorten its service life, which may cause considerable economic losses due to long-term shutdown.

Applications:Barite, quartz, feldspar, mica, calcite, talc, apatite, gypsum, fluorite, limestone, dolomite, diatomite, ceramic soil, clay, marble, granite, fly ash, kaolin, calcium carbonate, slag, bauxite.

Raymond Mill is suitable for grinding of all kinds of materials whose Mohs hardness is below 9.3, such as calcium carbonate, barite, dolomite, calcite, limestone, kaolin, bentonite, marble, gypsum, quartz, feldspar, clay, talc, fluorite, clay, white mud, mica, refractory material, glass, total about 1000 kinds of materials.

1. High efficiency and precision classifier, unique airtightness, which canensure the quality of end products. 2. The wear-resistant volute can effectively improve the material liquidity, decrease the air volume loss and avoid air energy loss.3. The bevel gear overall dive can achieve higher transmission efficiency, easy to install and adjust, long service life and lower cost.4. Inner thin oil lubrication system can realize lubrication between main bearing and drive bearing without any additional lubrication pump, easy to maintenance.5. The curved surface shovel with split design, only the blade to be replaced during maintenance, thus the shovel has long service life.6. The isolated cyclone collector can effectively improving the classifying efficiency and accuracy.

After the materials enter the grinding chamber of the main frame, the grinding roller swings outward and presses closely upon the grinding ring due to the centrifugal force generated by the rotation of the main shaft. The blade carries materials to the space between the grinding roller and grinding ring, and materials are ground as the grinding roller rolls. After being ground, the powder is selected by classifier via the cycle wind of the blower and the rough powder will be back to the grinding chamber for regrinding. The qualified powder is brought into the powder collector together with airflow. The powder comes out as end products while the airflow goes back to the powder collector in cycling to make the machine work normally. The remained airflow comes out after purification by dust filter.
