Pyrite Raymond Mill Equipment

Henan hongxing machinery is a professional manufacturer of the raymond mill.We have been offering the raymond mill to many countries for many years.Raymond mill (also can be called raymond grinder) is used for grinding 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, potash feldspar, talcum, marble, ceram and slag, dolomite heat preservation materials, chemical materials and so on (more than 280 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.

With its high quality products such as iron ore concentrator, vibrating feeder, jaw crusher supplier, raymond mill, rotary kiln, henan hongxing mining machinery co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.

The whole system of raymond mill consists of main frame, decelerator, classifier, piping device, blower, jaw crusher, dustpan elevator, electromagnetic vibration feeder, and electric switch box motor, etc.Its passing ratio achieves 99%, this is what other mill cannot reach.

So far, we have established a whole production chain, of which main products cover stone crushing & screening equipments: jaw crusher, cone crusher, impact crusher, vertical impact crusher, hammer crusher, vibrating feeder, oscillating screen, sand washer, belt conveyor;and grinding machinery: raymond mill, high-pressure suspension mill, ultrafine and roller mill, ball mill and so on.They are widely used in the industry of mining, construction materials, chemicals, metallurgies, transportation, hydraulic engineering and so on.Our products are not only renowned in more than 20 provinces and cities in domestic markets, but also have being sold popularly in more than dozens of countries and areas all over the world like eastern europe, middle east, africa, south asia, southeast asia, oceania, and central and south america etc.

With the improvement of the requirement of environmental protection, companies manufacturing raymond mill should do further research on the reduction of the machine noises and take some necessary measures,cement making plant keep the width and degree of the noise pollution into control.Its development should go toward high technology and efficiency, low noise pollution and energy consumption,portable crusher fewer accidents and fewer ware and tear.

At this time, the country's imports of raw ore more offers, limiting domestic ore reserves, with the high cost of additional pricing, we are exposed to a lot of domestic iron ore business customers have greatly influenced the financial crisis, ore processing market stagnated in some coastal areas, together with the latest and most critical national policy also has excellent impact, obviously national environmental safety requirements, need all the minimum capacity, the largest consumer dynamic, large-scale polluters disappear in 2015, but with the ore powder processing enterprises, is the goal of consolidation.As a result, domestic ore powder processing tool department increases raymond mill specifications, not only low energy consumption, manufacturing, environmental protection is now a component in the first reference.

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 whole structure of raymond mill is composed of a rolle mill,driving system, classifier, pipeline device, blower, finished cyclone collector , jaw crusher, bucket elevator, electromagnetic vibration feeder, electric motor.The raw materials by jaw crusher less than 20mm and lifted by the elevator to the storage hopper, then after vibrating feeder evenly and quantitatively and continuously into the main machine grinding, grinded powder was blow by airflow away.Through the classifier separated, consistent with the powder fineness with air flow through the pipeline into the cyclone collector, were isolated and collected, and then by the powder in tube is discharged into the finished powder.Air flow from large cyclone collector is arranged at the upper end of the air return pipe suction blower.The air current of the whole system is a closed loop, and flow circulation in the positive and negative pressure condition.Material availablefor nonflammable,non-explosive and brittle materials with mohs hardness less than 7.Moisture content is less than 8%,.Such as :limestone, calcite, fly ash, calcium carbide, kaolin, calcium carbonate, coal gangue, gypsum, grain slag, mn ore, coal dust, bentonite, barite, marble, talc, refractory material.

Grinding is the last process of concrete produce and also is the most current consuming working procedure.Concrete clinker get grinded into the right size.The smaller the particle size is, the better the final concrete is.There are many grinding machines suitable to grind the concrete clinker, such as ball mill, vertical mill, high pressure suspension grinding machine and raymond mill , etc.We will choose suitable grinding machine for you according to your requirements.With reliable quality and certification authority, you can trust us.

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.
