4. Introction: Raymond mill, also known as Raymond mill, English full name: raymondmill. It is suitable for all kinds of mineral powder preparation, coal powder preparation, such as raw meal ore, gypsum ore, coal and other materials of fine powder processing. From the appearance, it looks like a steel container standing upright, with air inlet and outlet, and feed inlet in the middle. There is a motor at the lower part of the mill to drive the internal grinding rod and disc to rotate to crush or grind the materials to be ground. The finished materials are blown up by the air at the air inlet. There is a separator at the upper part of the mill to separate the coarse and fine powders, and then the coarse and fine powders are collected through the air outlet of the mill. Scope of application: after years of practice and continuous improvement, the structure of R-Raymond mill has been improved day by day, with the advantages of high efficiency, low energy consumption, small floor area, less capital investment and no environmental pollution. Therefore, it is widely used in the grinding processing of mineral procts in the fields of metallurgy, building materials, chemical instry and mining. It is suitable for processing all kinds of non flammable and explosive minerals with Mohs hardness below grade 7 and humidity below 6%, such as gypsum, talc, calcite, limestone, marble, potash feldspar, barite, dolomite, granite, kaolin, Pengrun clay, Maifan stone, bauxite, etc Iron oxide red, iron ore, etc. the fineness of the finished proct is between 613 μ m ~ 440 μ m (0.613 mm - 0.44 mm). Through the joint action of the analyzer and fan, it can meet the requirements of different users. Working principle Raymond Mill smashes the bulk raw materials to the required feed particle size, then the materials are transported to the storage bin by the bucket elevator, and then evenly sent to the grinding chamber of the host machine by the electromagnetic vibration feeder. The materials entering the grinding chamber are ground between the grinding roller and the grinding ring, and the ground powder is carried to the analyzer for classification by the fan air flow, The fine powder meeting the fineness requirements flows through the pipeline with the gas into the large cyclone collector for separation and collection, and then discharged through the discharger to be the finished proct. In the working process of the main engine, the blade system plays a very important role. It is located at the lower end of the grinding roll. In the process of rotating with the grinding roll, the blade lifts and throws the material into the ring of the grinding roll to form a cushion layer. The material layer is crushed by the outward extrusion force generated by the rotation of the grinding roll, so as to achieve the purpose of pulverizing. Structure features Raymond mill is mainly composed of main engine, analyzer, blower, cyclone separator, pipeline device, motor, etc. The main engine consists of frame, air inlet volute, blade, grinding roller, grinding ring, cover and motor. Auxiliary equipment includes jaw crusher, stpan elevator, electromagnetic vibration feeder, electric control cabinet, etc. users can choose flexibly according to the site conditions. 1. The whole machine is of vertical structure, with small floor area and strong systematicness. It can form an independent proction system from raw material rough processing to conveying to milling and final packaging. 2. Compared with other grinding equipment, the pass through rate is as high as 99%. 3. The main driving device of Raymond mill adopts sealed gear box and belt wheel, with stable transmission and reliable operation. 4. The important parts of Raymond mill are made of high-quality castings and profiles. The process is fine and rigorous, which ensures the rability of the whole set of equipment. 5. The electrical system adopts centralized control, so that the grinding workshop can basically realize unmanned operation and maintenance. Installation and debugging (I) preparation before installation of Raymond mill 1. When Raymond mill is not installed at the operation site, it should be properly kept. The exposed surface should be coated with anti rust grease, and the sun and rain should be avoided, so as to prevent the body from rust and water. Maintenance system should be established. 2. The factory building and foundation shall have enough height and installation position according to the installation foundation drawing of Raymond mill. The foundation of Raymond Mill shall be made of high-grade cement and shall be embedded with steel bars before the foundation can be poured, and the conit or cable trench shall be embedded. After the cement foundation is poured, there must be a 15 day maintenance period. 3. It shall be equipped with 2-3T lifting tools for the installation and maintenance of Raymond mill. 4. If the Raymond mill has been used for more than 6 months since leaving the factory, clean and inspect the central shaft system, transmission device, grinding roller device and analysis oil pool of the main engine. After cleaning and inspection, add enough lubricating oil to all parts 2 Installation of Raymond Mill (see also the installation diagram of Raymond Mill) 1. First, lift the base of the transmission device into the pit and fill it, pay attention to control a certain height, then use the level to correct the upper plane "a", at the same time, install the transmission device on the "a" plane and fix it with bolts. 2. Main engine installation of Raymond mill. Before installation, rubber shockproof pad should be padded at the contact between the bottom plane of the base and the cement foundation and between the anchor bolt connections (see Figure), and then the frame level should be used to correct the "B" plane of the base. The correction points are four points of the cross cross line. At the same time, the two coupling halves "C" and "d" should be adjusted. The different axial degrees should be less than 0.20 mm, and the non parallelism of E1-E2 should not be more than 0.1 mm, "E1" and "d" The gap between "E2" should be kept within 5-8 mm. 3. The position and height of the pipeline device shall be installed according to the general drawing, and shall not be arbitrarily changed or heightened. All pipeline joints shall be sealed, and there shall be no air leakage after fastening. The electrical equipment shall be accurate and reliable, and the trial run shall be concted after the installation of each component 3 Raymond Mill commissioning (trial run by air) 1. Before no-load trial run, the roller device should be tightly rolled with mesh rope to avoid the contact impact between roller and ring, and then the main machine should be trial run by air for no less than 1 hour; The main engine should run smoothly, the oil temperature in the box should not exceed 80 ℃, and the temperature rise should not exceed 40 ℃. The rotation direction of the host and analyzer is shown in Figure 4. 2. The blower shall be started up without load and loaded after normal operation, and then the operation shall be stable without abnormal noise and vibration. The maximum temperature of rolling bearing shall not exceed 70 ℃, and the temperature rise shall not exceed 35 ℃. 3. The test run time under load shall not be less than 8 hours. After the Raymond mill works normally, there is no abnormal noise in the whole machine, and there is no air leakage at the pipe joints. After the test run, tighten the tightening solid again, and then it can be put into normal use. Before the operation of Raymond mill, it is necessary to check whether all the access doors are closed tightly, whether the gap between the jaw plate of the crusher meets the grain size of the feed, and adjust the speed of the analyzer to meet the grain size of the finished proct. Finally, start the machine in order. 1. Start the bucket elevator; 2. Start jaw crusher; 3. After the materials are stored in the silo, start the analyzer; 4. Start the blower (start at no load and load after normal operation); 5. Start the main engine of Raymond mill, and immediately start the electromagnetic vibration feeder. At this time, Raymond grinding work is to start. The operation sequence of Raymond mill is simple as follows: Start: hoist → crusher → analyzer → fan → main machine → feeder. When Raymond mill is shut down, all machines should be shut down in the following order: 1. Shut down the feeder first to stop feeding; 2. Stop the host in about one minute; 3. Stop the blower after blowing out the resial powder; 4. Finally, turn off the analyzer. Raymond Mill shutdown sequence is: feeder → main machine → blower → analyzer. Note: after the elevator transports a certain amount of material to the silo, stop the crusher first and then stop lifting. This item should be changed by the current storage amount. 5. Raymond mill is not allowed to refuel at will ring normal operation. To ensure proction safety, if abnormal noise occurs in any part of the mill or the load suddenly increases, it should be stopped immediately for inspection and troubleshooting, so as to avoid major accidents. When the machine is started up again, the resial material in the mill must be taken out, otherwise the current is too high when the machine is started up, which will affect the start-up. Maintenance 1, Raymond Mill in the process of use, there should be fixed personnel responsible for care, operators must have a certain technical level. Before the installation of the mill, the operator must receive necessary technical training to make him understand the principle and performance of the mill and be familiar with the operation proceres. 2. In order to ensure the normal operation of Raymond mill, the "safe operation system of equipment maintenance" should be formulated to ensure the long-term safe operation of the mill. At the same time, necessary maintenance tools, grease and corresponding accessories should be provided. 3. After the Raymond mill has been used for a period of time, it should be overhauled. At the same time, it should be overhauled and replaced for vulnerable parts such as grinding roller, grinding ring and blade. Before and after the use of the grinding roller device, the connecting bolts and nuts should be carefully checked to see whether there is looseness and whether the lubricating grease is sufficient. 4. When the roller device is used for more than 500 hours, the rolling bearings in the roller sleeve must be cleaned, and the damaged parts should be replaced in time. The oil filling tools can be manual oil pump and grease gun. After years of practice and continuous improvement, the structure of R-Raymond mill has been improved day by day, with the advantages of high efficiency, low energy consumption, small floor area, less capital investment and no environmental pollution. Therefore, it is widely used in the grinding processing of mineral procts in the fields of metallurgy, building materials, chemical instry and mining. It is suitable for processing all kinds of non flammable and explosive minerals with Mohs hardness below grade 7 and humidity below 6%, such as gypsum, talc, calcite, limestone, marble, potash feldspar, barite, dolomite, granite, kaolin, Pengrun clay, Maifan stone, bauxite, etc Iron oxide red, iron ore, etc. the fineness of the finished proct is between 613 μ m ~ 440 μ m (0.613 mm - 0.44 mm). Through the joint action of the analyzer and fan, it can meet the requirements of different users. Troubleshooting Raymond Mill in the process of using the fault, can be handled as follows: common fault 1: no powder or less powder, low output.

5. Brother, I also refer to the information on the Internet. I've just seen several companies recently, and the company you mentioned looks pretty good< Henan Zhongkuang Machinery Co., Ltd. is the most professional Raymond mill manufacturer in Zhengzhou, Henan Zhongkuang Machinery Co., Ltd. is the most professional Raymond mill manufacturer in Zhengzhou, and the most reasonable price of Raymond mill. Welcome new and old customers to buy it.

Henan Raymond mill is suitable for barite, calcite, potash feldspar Talc, marble, limestone, ceramics, glass and other non flammable and explosive mining, chemical, building materials, metallurgy and other instries with Mohs hardness no more than 7 and humidity less than 6% are used for pulverizing more than 280 materials. The particle size of finished procts can be adjusted arbitrarily in the range of 100-325 mesh
working process of Raymond Mill:
Raymond Mill evenly and continuously sends the materials to be crushed into the main machine grinding chamber. Due to the centrifugal force ring rotation, the grinding roller swings outward, presses the grinding ring tightly, and the scraper picks up the materials and sends them between the grinding roller and the grinding ring to achieve the purpose of crushing e to the rolling of the grinding roller
after the material is grinded, the fine powder is brought into the analyzer with the circulating air of the blower for separation. The fine and coarse material falls down for regrinding, and the qualified fine powder enters the cyclone powder collector of the finished proct and is discharged through the outlet branch pipe, which is the finished proct
in the grinding chamber, e to certain moisture in the ground material, heat is generated ring grinding, water vapor is evaporated, and the external gas is inhaled when feeding at the feed inlet, which increases the circulating air pressure and ensures that the mill works under negative pressure. The increased air flow is discharged into the st collector through the resial air pipe and discharged into the atmosphere after purification.

6. The drafting units of Raymond standard include Shanghai Metallurgical Mining Machinery Factory and Guangxi Guilin mining machinery factory; The former state-owned enterprise designated by the Ministry of mechanical and electrical of the people's Republic of China to proce Raymond machines. At present, the drafting unit of Raymond machine is still in proction, and Guilin mining machinery factory is still in proction.

7. Raymond mill is also known as Raymond mill. Raymond mill is a new type of mill to process ore powder instead of ball mill. The roller of Raymond mill is tightly pressed on the grinding ring under the action of centrifugal force. Therefore, when the roller and ring are worn to a certain thickness, the output and fineness of finished procts will not be affected. The replacement cycle of roller and ring of Raymond mill is long, which eliminates the disadvantage of short replacement cycle of wearing parts of centrifugal mill. The mill is suitable for processing more than 280 kinds of non flammable and explosive materials in mining, chemical, building materials, metallurgy and other instries, such as barite, calcite, potash feldspar, talc, marble, limestone, ceramics, glass, etc., with Mohs hardness no more than 7 and humidity less than 6%. The particle size of finished procts can be adjusted within 80-425 mesh

8. Raymond
mill. Suitable for various kinds of mineral powder preparation, coal powder preparation, such as raw meal ore, gypsum ore, coal and other materials of fine powder processing
the working principle of Raymond mill is that the grinding roller rolls tightly on the grinding ring under the action of centrifugal force, and the material is picked up by the shovel and sent to the middle of the grinding roller and ring. The material is crushed into powder under the action of grinding pressure, and then the powdered material is blown up under the action of fan. After passing through the analyzer, the material with the required fineness passes through the analyzer, and if it fails to meet the requirements, it will return to the grinding chamber for further grinding, The material from the analyzer enters the cyclone separator for separation and collection.
