Whether the feed size is too small or too large, it will affect the production of raymond mill.When the mixed material with particle size less than 10 mm is more than 70%, the powdery materials will be too many, then they will be basically free from being squeezed and falls freely.Raymond mill loses the meaning of its extrusion grinding.When the mixture contains a bulk material with a particle diameter of over 150 mm, the roll gap is forcibly opened and the bed is destroyed.Therefore, we advise to screen the material with a vibrating screen firstly before the milling process to filter the fine powder and large pieces of material larger than 150 mm to avoid hem entering the raymond mill.
The water content of the material should be less than 6% (can be kneaded into a ball by hands without water seepage) in raymond mill.Whether the material is too wet or too dry, it will directly affect the capacity of raymond mill.Studies have shown that when the comprehensive moisture content of the material is higher than 1.5%, the output is reduced; when it is higher than 2.5%, its reduced by 15% to 30%; when its higher than 3.5%, the fine powder in the raymond mill will adhere to the grinding body and the liner, which greatly reduces the grinding efficiency and even powder selection and dust removal system failures will be increasing or the raymond mill will be forced to stop.
Therefore, the comprehensive moisture content of the material should be controlled within 1.5%.Materials with excessive humidity can be dried naturally or by a dryer.However, we shouldnt dry the material as much as possible.If the material is too dry, its speed in the raymond mill will be very fast, which will affect the quality of the final product and produce large dust pollution during grinding.In this case, we can properly spray water to the feed mouth to increase its humidity.
Raymond mill field must do what financial recession.December two in the morning, beijing information, foreign media that china build skyscrapers, mineral asset is expected to generate a desire to develop the necessary axle vehicles and soaring commodity costs and benefits over the past decade, and now, these commodities exporters are feeling a heavy blow to china's economic slowdown this boom.Bad effects of such a large exporter of australia and brazil, as rich guinea, indonesia and mongolia resources, most of the country's mineral exports and economic environment in many ways and employment, such as the impact is enormous.
The raymond mill can just process single raw material.Stone production line our mill has different materials of grinding medium (mainly for grinding roller and grinding ring) to meet the requirement of processing different raw materials, so that not only can extend its life but also increase production.If the user changes the original intention for long-term and process other raw materials, it needs to replace the suitable grinding roller and grinding ring, the universal grinding medium is not the best choice.
We should do our effort to do the best configuration to achieve the maximum efficiency of raymond mill.It is necessary to achieve the optimal allocation of all possible factors, which will improve the material handling capacity.So that the material between the roller and grinding ring can get full grinding to speed up productivity.
Because the grinding force of raymond mill comes from the centrifugal force of the grinding roller, the speed of the main engine directly affects the grinding force.The low-speed driving shaft may be one of the reasons for the low powder yield.For example: for processing 200 meshes barite powder, the output of raymond mill is up to about 8-10 tph.At this time, the machines rotation speed is 103r/min, which is the best grinding speed.We should keep the rotation speed at this fixed number all the time or a reduction in production will be caused.
Raymond mill is widely used in barite, calcite, potash feldspar, talc, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass, insulation materials, mohs hardness of not more than 7, and humidity below 6% of non-inflammable and explosive ore, chemicals, building materials, etc.280 kinds of material for high fine powder generation and processing, product size in the 50 - be adjusted within the 325, some of the finest materials to 600 mesh.
Raymond mill needs to be equipped with the user, hoist, electromagnetic vibrating feeder, electric motors and other components.Materials are crushed to the desired particle size, the whole structure is raymond mill by the host, analysis machine, plumbing fixtures, air blower.Hoist the material sent by the hopper, then by vibrating feeder will feed into raymond uniform continuous grinding powder machine host indoor, because the centrifugal force, roller swing outward rotation, the squeeze on grinding ring, between the shovel blade materials to the roller and grinding ring rolling mill rolls by fine grinding to achieve the purpose of the material after grinding with circulating air blower being brought into the analysis machine for sorting , fine through coarse material regrinding, qualified powder into the air waste cyclone powder collector through the powder discharge pipe, is finished.
Experts from this industry stress that on the energy saving and consumption reduction problem, all companies should actively think wide and should not pursue blindly with the plan of compound driving force.After all, the engineering equipment is not a crushing toy, relying on power operation is just a expedient, and every way that is able to promote the energy saving and energy consumption is worth to be encouraged.Zenith machinery believe that if the mining machinery manufacturing companies want to gain more benefit margins, the energy-saving series raymond mill is your perfect choice.
Once it has been extracted, it must pass through the highly technical process to isolate and crush the magnetite concentrate for direct export or for conversion into pellets.The first phase of magnetite ores transported by primary crushing, which is located in a pit and can be jaw crusher or cone crusher.Crushed ore is transported to the hub, which consists of a series of mills and other processes.Each of the eight mills worth more than 17 meters in height and 12 meters in diameter.Mills, such as ball mill and raymond mill, produce a fine stream of magnetite ore, which can be separated by magnetic separators or concentrate or waste.As a result, the concentrate will be thickened and stored before it is pumped into the 25 kilometers to the port where it is filtered to reduce the humidity.
