The china clay (kaolin) is grinded into fine powder by grinding machines.The common grinding mill is raymond mill.The raymond mill is the traditional grinding mill and popular around the world.It features small occupying space, good uniformity of fineness of final powder, electricity system without operator.Beside, hongxing machinery have developed mtm trapezium mill and mtw trapezium mill as substitute of raymond mill for grinding china clay (kaolin).It is lower consumption, lower investment, and more environment friendly, smaller occupation area than raymond mill.With its high quality products, hongxing machinery has ascended in the front rank of the world in the exporting of mining equipment.

Henan kefan mining machinery co.,ltd.Is a mining machinery which mainly supply mining equipment, such as crusher,brick making machine,briquetting machine,rotary dryer,jaw crusher,raymond mill,grinding mill,cement mill,autoclaved aerated concrete,block machine,granulator,rotary kiln,etc.
Aboard hammer and liner plate of impact crusher are easy to wear, which need routine maintenance.At present, the aboard hammer and liner plate in our country mainly made from high manganese steel.For the difference of heat treating materials, its service life is different.Our country also developed a kind of impact hammer made from low alloy white cast iron or high chromium iron, which has the features of high hardness, good abrasive resistance, simple production, low investment, and has achieve a good effect.In order to meet the development needs of large quantities of mineral processing trends, crusher, mill product will inevitably need to have a greater degree of improvement in production and processing capacity.That will lead to the crusher, mill production enterprises accelerating technology research and development to introduce more types of efficient powder grinding equipment.According to different requirements, we need to select different types of mill to achieve the purpose of energy saving and high production.Some series of non-metallic ore mill is applicable to the processing needs of the graphite of different particle size of different industrial applications.There are raymond mill, high pressure medium speed mill, tricyclic micro powder mill, etc.And some types is specializing in powder production, such as high-pressure micro powder mill, ultrafine mill.With the development of china's economic reform, and the awareness of global environmental protection, environmental pollution caused by production and processing of mineral resources gradually against humanity.Therefore, people began to look for more efficient and environmental friendly equipment.Thus can ensure the production as well as more environmental friendly, which is not only an incentive but also challenge for mining machinery.It also promotes the continuous improvement in the skills of the crusher and mill, and guides the mining machinery develops in a benign way.After many years of practice and continuous improvement, the raymond mill is becoming better and better in structure. it has many features with high efficiency, low power consumption, small floor space, less capital investment and less environment pollution.In the carbon steel aboard hammer, some manufacturer use up weld 64 and up weld 64a welding rod to surfacing a layer, or use high-manganese steel electrode to surfacing in the high-manganese steel electrode, these methods can reduce wear, and repair old aboard hammer or impact plate.The shape and fix methods of aboard hammer is important to maintenance.The shape of aboard hammer should be convenient to dismounting, and improve the metal utilization ratio.The weight of aboard hammer should be exact, and its error should not be exceeding 0.5kg that to make sure the stable of machine.During rotor static balance test, rotor should not rotate 1/10 circle when it stop in any point.Therefore, this new type of raymond mill is widely used in metallurgy, building materials, chemicals, mining minerals for grinding materials processing.Graphite materials and their composites as new materials of the 21st century, there no doubt will have a great development.And graphite has been applied in many fields, corresponding to some of the emerging high-tech industry.The mill industry is willing to provide a more superior product for the rapid development of the graphite.
Because the investment and application of the not-energy-saving equipment lead to serious environmental pollution, then now we can conclude from it that we cannot only focus on industrial manufacturing but not care about what is going on in the outside world.According to the materials that collected by the research and development department in zenith machinery, the engines that are configured in the existing old crushing engineering products are fit out on the product the moment that the new machines get down from the assembly line, the emission amount of carbon dioxide from theraymond millis much higher than the existing industrial standard.The hydraulic system that is used in the old mechanical products has the problems of gas release and oil leakage which is also one of the factors that lead to environmental pollution and resources waste.Although these ancillary parts can be changed, if the customers dismantle and overhaul all the hydraulic system, the cost will be extremely high.
Raymond mill is popular in some clay processing plant, which features of small space and strong integration capability.The final grain size of clay powder is between 0.613mm-0.044mm.The raymond mill adopts electromagnetic vibrating feeding machine, which ensures even and regular feeding.The electricity system of the raymond mill is centrally controlled, so no people are needed in the operating room.
Raymond mill working principlethe whole machine is collocated with jaw crusher, elevator, hopper, electromagnetic vibrating feeder, main unit, classifier, collector, cloth deduster and high-pressure blower.The working principle is as follows: load the stuff for grinding evenly and continuously into the grinding chamber of the main frame.Due to the centrifugal force in rotation, the roller swings go outward and presses closely upon the ring.The shovel carries the stuff to the space between the roller and ring.When the roller rolls, the stuff is thus grinded.After being grinded, the stuff is to be routed to the classifier along wind belt of the blower and the rough powder will be put back to the grinder for regrinding.
If you're interested in mining machinery such as jaw crusher, impact crusher, ball mill, raymond mill, snad maker, we believe that henan hongxing machinery is your nice choice.
Marius kloppers, chief executive of bhp billiton, the world's largest mining company, told investors that the group had seen customers 'behave conservatively in the light of global uncertainty'.He added that companies were keeping a close watch on inventory levels, in light of 'the potential need to tailor their plans if the global economic uncertainty continues'.As a leading global manufacturer of crushing and milling equipment, we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete stone crushing station.We also supply individual jaw crusher and raymond mill as well as spare parts of them.
