About raymond millraymond mill (raymond roller mill) is applicable to the grinding and processing of more than 280 kinds of non-flammable and non-explosive materials with hardness less than 7 and humidity less than 6% in mining, construction, chemical industry and metallurgy, such as barite, calcite,feldspar, talcum, marble, limestone, clay, glass.The fineness of the finished product can be adjusted from 100 meshes to 325 meshes according to requirements.It is the main and widely used grinding machine.After many years of practice and improvement, its structure is getting perfect day by day.For low consumption, low investment, environment friendly , small occupation area, and more efficient than the traditional mill, it is widely used in the field of metallurgy, building materials,chemical industry and mining to process powder.Structure of raymond mill1.The whole plant is a vertical structure of strong systematic characteristic, so it occupies small area.It is an independent production system from crushing of raw material to grinding and packing.2.Compared with other milling plants, its passing ratio achieves 99%, this is what other mill cannot reach.3.Driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reliably.4.Main parts of the whole plant are made from cast and steel of high quality.The techniques is so subtly that insures the durability of whole plant.5.The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room.Raymond mill maintenance and repair1.Operate the equipment have to be technically trained to know the principle and rules of operation.Someone should be specially selected and put in charge of the operation.2.To ensure normal operation of the equipment, a manual containing strict rules and procedures for its operation, maintenance and repair should be well prepared and followed.Tools, replacement parts for maintaining, repairing and lubricating oil and grease must be available for immediate use.3.After a period of usage, the equipment should be checked, to replace worn-and-torn parts such as rollers, rings and shovels.Be sure to fasten connecting-bolts, nut collars to fix rollers properly.Be sure to lubricate the parts sufficiently.4.Roller should be replaced after 500-hours use.It is to check and wash bearings in them and replace broken ones, and then fills enough oil and grease (with oil-pump or grease-gun).
Now, they don't feel so blessed.Sources say that not only are the veteran skilled workers gone from the industry, but also the younger generations - those at ages when people historically went into manufacturing - want nothing to do with factory life.They've been tempered by a negative image many people associate with manufacturingof vibrating screen and other mining machines such as raymond mill.They - and their parents, in many cases - believe it is dirty and dangerous, even though advanced manufacturing is none of the above, experts say.That has been a problem for manufacturing since the mid-1970s.But now the sector faces a new dilemma.It was counted out for so many years, and its rebirth has been totally underreported.
Raymond mill (raymond roller mill) is applicable to the grinding and processing of more than 280 kinds of non-flammable and non-explosive materials with hardness less than 7 and humidity less than 6% in mining, construction, chemical industry and metallurgy, such as barite, calcite, feldspar,talcum, marble, limestone, clay, glass.The fineness of the finished product can be adjusted from 100 mesh to 325 mesh according to requirements.Feature of raymond mill:.
If you want to change the product fineness of raymond mill (especially with low mesh to high mesh),wet magnetic separator you must pay attention to clean up thick powder and large particles on the the classifier, piping, cyclone dust collector, and finished products warehouse.Otherwise it will easily cause large particles pollution.The general cleaning method: after cleaning up the mill cavity, the residual material in the wind box,drum dryer stop the main engine and stop feeding material, transfer the classifier to the high speed which is suit for processing corresponding fine powder, then open the blower at maximum, meanwhile start the wall vibrator on the product warehouse.Cement equipment we should run more than 4h in this way, in this process you must appropriately beat the pipe, cyclone dust collector and finished products warehouse shell to help remove adhesive residue.Don't be boring to ignore this key process, especially in the production of ultrafine powder which is strictly limited to the large particles.Rotary dryers.
Growth in 2014 along with my manufacturing to high-performance, low-cost, non-polluting, energy-efficient route, raymond mill insisted improvement in the price.Raymond mill efficiency is actually a common recognition of consumers praised this year introduced a new manufacturing and raymond mill will bring a new round of product sales growth.Volatility has just launched a new mercury rick raymond mill cost impact in some way, and many years ago, the cost went up eight.5%, but this does not affect sales, but rose 40%, compared to previous years, there are many additional demand production of ultra-fine grinding, grinding micro-grinding, high strain increasing heart in customer orders.Raymond mill price volatility: there are a lot of reasons.Diversification of raymond mill machine model, which is usually almost nothing to say, different roles, different designs, costs will vary, so when buyers must be selected according to their needs.2, according to raymond mill's material, it is carefully made from steel, so different allegations value fluctuations raymond mill steel.Three.Choose a different raymond mill machine brand, raymond mill huge difference between the value of nature.Needless to say, such an important and regardless of the quality or after-sales offer you safe from large-scale manufacturers, each one will lead to price volatility.
World economic climate by the financial crisis, "black storm." some weakness in different sectors, especially in the cement industry, steel industry, so milling market was also affected, but also the historic raymond mill machine is a big trauma, it is actually often volatility, in many cases, some the famous company in redmond "zero profit" product sales.But in 2014, china's economic plight has slowly revitalized indicators.It begins smooth and orderly development, the new round of investment and income approaches, the value of raymond mill is an inevitable disturbances and fluctuations.
And this kind of raymond mill can be applied to the powder manufacturing with high-pressure and closed circuit in the field of small mines,chemicals, building materials, metallurgy, etc.And the raymond mill has found its extensive application to crush the non-flammable and explosive materials with the mohs of lower than 7degree and moisture of below 6% and so on.This kind of raymond mill adopts the advanced structure and are developed on the basis of large-size raymond mill with the advantages of high-efficiency ,low energy-consumption, small cover area, and low investment cost.And the wind classifying stream process in the circular working process of wind machine-grinding shell-and the inner circular of the wind machine.So the powder dust is little than the high-speed with the characteristics of clean peration environment and no pollution environment.
Industrial mill has widely used for grinding and processing of mining materials and products in such industries and fields as metallurgy, building material, chemistry and mining.According to the difference of grinding material and its granularity, the commonly-used grinder types are raymond mill, ladder-shaped mill and three-ringed one.
Raymond mill is mainly applied to the powder processing of mineral products in industries of metallurgy, construction, chemistry, and mining etc.It can produce powder from more than 280 kinds of non-flammable and non-explosive mineral materials with mohs hardness below 7 and humidity below 6%, such as barite, limestone, quartz, calcite, granite, porcelain clay, basalt, gypsum etc.The final size is between 613micron and 440 micron(0.613mm-0.044mm).
The available grinding mills include raymond mill and other roller mill.But usually the processing capacity of the raymond mill can't meet the big demand of the clients.We know the amount of the rollers determines the processing capacity of grinding mills, and at present the most rollers of a raymond mill are 4 so its capacity can be at most 4 ton per hour.So a new roller mill with 6 rollers has been the popular one and achieves high repute from the users, which is named super pressure trapezium mill.It is the real king of roller mills and its capacity can be up to 20 tons per hour base on limestones materials.Also, another new one is called high pressure suspension mill,whose capacity can be about 10 tons per hour.The pre-homogenization process makes the materials storage and homogenization.
The powder grinding equipment will be larger, more environmentally friendly and more intelligent.For this reason, hongxing machinery made technological upgrading on the basis of the original raymond mill, the main machine and the reduction box adopt elastic sleeve dowel pin shaft coupling which effectively prevent the easy-breaking phenomenon and promotes the reliability of the machine.The analytical engine adopts high density leaves and frequency control which is able to improve the powder dressing fineness and production capacity.Compared with the common powder collector, by-path powder collector has little damage on pressure and high powder collecting efficiency which is beneficial to collect the micro powders and particles that is difficult for the common one to collect so that it has the advantages of protecting the environment.
