From the 1906 C.V.Grueber Curt Von Grueber in the southern suburbs of Berlin machinery manufacturing factory to create, to the present application of a new type of Raymond Mill in the field of industry widely, Raymond mill has gone through nearly 100 years of history, the manager how many times has experienced many challenges, turning, won many times to succeed.
Initially, Raymond mill is from Germany to USA Raymond centrifugal hoop roller mill patent application, in view of Berlin's coal industry equipment, for hard coal, high ash content and Germany, in view of the high grinding force equipment, but the results are not satisfactory. Because the roller grinding force in the first generation of Raymond mill coal mill (centrifugal force) by grinding roll diameter and speed limits, at the time of the mill is only applicable to soft, easy raymond mill material and low ash coal is good, can not meet the requirements of Germany, abandoned, was retired. However, this device was accidentally meet American coal grinding requirements, so that the USA Raymond coal mill has been widely promoted and applied, or whether it can spread from today, yet.
In the 1925E.C.Loesche and up to the first generation of Raymond mill grinding structure, improvement, application and before the opposite grinding principle, called improved Raymond mill. Soon, the Mongolian grinding patent soon to be American Combustion Engineering Company (Combustion Engineering) production, purchase, it improved the ventilation with positive and negative pressure direct blow in two ways, but because of limited hoop roller mill, the roll diameter increased slightly, but the Raymond mill force increases a little, the effect is still not ideal.
Since then, the combustion engineering company branch of Raymond also plans a new round of VR mill, produce, its structure and Loesche mill is very similar, different is that it uses a cylindrical roller and belt with a 15 degree angle of the inclined surface grinding mill, and is also provided with a protection device, in order to to prevent metal to metal contact between the grinding roller and the grinding disc. In addition to the mill grinding roller can be lifted ahead before the start, it can reduce the starting torque of the motor.
Raymond Mill in America industrialized application, usually used in the preparation of the coal mine, and later introduced the domestic industry, and the application is also developed, become the milling industry.
Because the indoor temperature is too high the Raymond mill which has 2 points
First, pay attention to each lubricating point of the Raymond mill working state, such as bearings, roller and so on, the timing quantitative oil lubrication equipment components, ensure good working environment, increase the flexibility of the operation of the components, reducing the friction between the contact surface, prolong the service life of equipment, thus avoiding the grinding chamber the problem of high temperature.
Second, according to the working condition of ventilation, can adjust the grinding chamber, which is open to the external air flow ventilation pipe, and the grinding chamber convection occurs, so that the flour milling machine room temperature slowly decrease, avoid high temperature of the grinding chamber device.

Raymond mill is ideal for processing of bentonite, the raymond mill processing of bentonite is known as universal  clay, bentonite is also known as bentonite and bentonite, bentonite with good physical and chemical properties, as a binder, suspending agent, thixotropic agent, stabilizer purification, bleaching agent, filler, catalyst feed, etc., are widely used in metallurgy, petroleum, chemical industry, environmental protection, food, casting and other industries, so the bentonite is a kind of extensive use of natural materials, bentonite has strong moisture absorption, can absorb the equivalent volume of 8 to 20 times of water and swells to 30 times; dispersed colloidal suspension in the water medium, and has a certain viscosity, thixotropy and lubricity, admixture and sediment have plasticity and cohesiveness, strong cation exchange capacity and adsorption capacity.
raymond mill is mainly used in metallurgy, building materials, chemical industry, mining and other mineral products grinding processing, processing all kinds of grinding of bentonite, quartz, feldspar, calcite, talc, barite, fluorite, rare earth, marble, ceramic, bauxite, manganese ore, iron ore, copper, phosphorus ore hardness in the following 9.3 humidity in 6%, non flammable and explosive mineral materials.
As one of the milling machine manufacturer professional, will quality, to the letter, strain every nerve to meet customer demand.

American environmental protection foundation, "global justice" and American Lung Association and many other institutions 11, Washington D.C. Columbia Federal Circuit Court of appeals filed a lawsuit, sued the Obama administration. According to the complaint, the Obama administration in September to withdraw a ozone standard regulatory legislation decision, the political considerations in public health, not only the "irresponsible", but also in violation of the "Clean Air Act" requirements. With the development of the times, the acceleration of urbanization, the environmental awareness of people increasingly enhanced, the overpressure vertical roller mill machine adhere to environmental protection and energy saving, and take the road of sustainable development, quality of excellence!
The overpressure vertical roller mill by the host, high density powder selecting machine, connecting pipe, high efficiency and energy saving centrifugal induced draft fan, box bag dust collector, crusher, bucket elevator, hopper, electromagnetic vibration feeder, electric control cabinet, etc.. The host through the speed reducer drives the central shaft to rotate, the top of the shaft is connected with the frame, frame is provided with a grinding roller and the formation of the swing fulcrum. The grinding roller not only around the center axis of rotation, the revolution also around the ring, the roller itself due to the friction and rotation. The model uses the flexible ladder work surface, roll linked pressure connection, five mill patented technology, pioneered the overpressure vertical roller mill of the highest level in the world.
The outstanding advantages of the vertical roller mill:
1 high density, high accuracy of the impeller device.
2 high efficiency and energy saving centrifugal induced draft fan. Fan in the whole operation process of mill, played a crucial role, trapezoid abrasive impeller fan energy saving and efficient, greatly improving the efficiency than the straight blade type fan.
3 compared with Raymond grinding, patented product overpressure ladder mill makes the gap adjustment end select leaf powder machine with a convenient, fast, greatly improves the product precision.
Always believe that product quality is the life of enterprise, the company has an experienced team, after sale service, skilled spread all over the country tracking service. In the future, we will continue to increase innovation, for the mine enterprise never stop tomorrow!

raymond Mill equipment will appear such problems in the use of the process, so this problem is not only the operation of equipment, including the equipment itself, is the maintenance of equipment and maintenance issues, problems and equipment, how can we better maintenance and repair equipment problems.
In the actual production, a large mill,
Raymond Mill machine and other noise from is now grinding machine manufacturers has not solve the problem. There are many factors which produce noise and vibration is one of the important reasons, so how to reduce the noise in the mill production, the following are some commonly used methods of user.
The Raymond mill will produce vibration why at the time of production? The main reason is due to milling equipment at the time of manufacturing the wheel imbalance, machining error, so produce noise. In fact, noise and many aspects are involved, such as parts of the material, manufacturing and equipment, structure design, the roller bearing level positioning accuracy and other factors are closely related, in the face of these problems, how do we solve it?
Only by understanding the causes and sources of Raymond mill and grinding equipment noise, targeted to solve and improve. To reduce the noise, the first must be accurate equipment precision, the components of the equipment must be installed according to the tolerance requirements; second, in use process must ensure good lubrication, only in this way can play a damping effect, but also improve the gyration precision grinding roller and roller bearing design steps, do these two points can reduce the noise.
