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.
There are many types of equipment to process bentonites.In accordance with the requirements of bentonite products, we can choose the suitable machines, which include raymond mill, ball mill, high pressure suspension mill, hgm three-rings & medium-speed micropowder mill and super pressure trapezium grinding mill etc.The output size from raymond mill varies from 440 to 613 microns (0.44 ~0.613mm or 425~100 mesh).These final products sizes can meet the demands from different clients through the combined effect of the separator and the blower.The final products sizes from the high pressure suspension mill can be adjusted between 80 mesh to 425 mesh (the fineness can be up to 1000 mesh).Through being equipped the special device, it can produce 30 ~80 mesh coarse powder; and three-rings & medium-speed micropowder mil can even produce 325-3250 mesh final powder, of course the capacity decreases by 350 ~ 6000 kg/h.And more details about these grinding mills ,please refer to the specifications in our products brochures or on our website.(please note that the specifications mentioned above will change according to the conditions such as the materials, the moisture, even the same material name from different areas and so on.).
Once the high-temperature material is fed into the raymond mill, the tendency of the nip between the pressure roller and the material will be increased and the granulation between the granules of the bed wont be formed, resulting in the ramming.The actual situation shows that when the temperature of the clinker exceeds 80 c, the output will decrease.Therefore, when grinding cement without mixed materials or with a small number of mixed materials, the temperature of the clinker should generally be controlled below 80 c; and when grinding the slag cement or cement with lots of materials, it should be controlled below 100 c.If the temperature of the material is too high, water can be sprayed into the cooler or on the clinker belt to allow it to cool.
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.
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.
Our copper ore grinding mills include ball mill, raymond mill, super thin mill and coarse powder mill.Ball mill is the traditional horizontal grinding mill and has very wide use, which can grind many kinds of material.Raymond mill is the vertical grinding mill, which is popular in many countries and has very long history.Super thin mill is special for super thin grinding and coarse powder mill is special for coarse powder grinding.You can choose acceptable copper ore grinding mill depends on your copper ore size, hardness, capacity and your expense budget.
Each position on the cylinder to open a manhole,high-capacity raymond millwhose role is to repair and replacement of the grinding body a variety of wearing parts (set for linings, diaphragm plate); loading and unloading of the grinding media and drawing mill sieve analysis curve to the mill sampling; stop grinding check the mill operating conditions.
The raymond mill is used to grind materials in the fields of building materials, mining, metallurgy and chemical industry.The materials must be non-flammable and non-explosive materials such as: limestone, calcite, barite, dolomite, potassium feldspar, marble, talcum, gypsum, kaoline, medical stone, rock phosphate, manganese ore, iron ore, glass, ceram, active carbon, carbon black, fireproof materials, heat preservation materials, chemical materials and so on(300 kinds of materials).The materials should have the hardness less than 7 in moh's scale and humidity less than 6 percent.The granularity of the end products can be adjusted from 30 to 325 meshes.
In the ore selecting industry, henan hongxing mining machinery adopts the latest technological craft and equipment, helps the customer crush, classify, grind and select the iron ore, diamond, barite, etc.The coarse crushing usually adopts jaw type crusher, vertical impact crushing equipment, cone type crusher, etc.With the granularity of 0-5mm.Then the material runs through vertical mill, super trapezium mill, raymond mill with selecting the end of the coarse grain.The coarse ore and fineness ore are used as the feedstock of ore grinding.After the ore grinding is the ore selecting with carefulness.At last, the concentrate of high grade and recovery becomes the acceptable product.
The raymond mill is one main products of our company.And as one of the biggest production base in china, our company have produced the raymond mill with better won in the raymond mill market.And abiding by the enterprising spirit of "quality first" and service principle of" customers primary", we company have put forward the operation idea of "good faith and truth seeking".
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.
Answer: the reason raymond abnormal vibration is feeding uneven or too small, large, sometimes small volume of material entering the raymond mill if it will lead to uneven thickness of the material layer on the disc, and even the roller impact shock absorber, resulting in grinding vibration.Faced with this situation the solution is to do a good job and stable feeding, appropriate adjustments feed rate or reduce the operating pressure, we can see, to understand the quantitative aspects of the raymond mill which plays a crucial role.
