Installation and operation process of Raymond Mill

Raymond mill is composed of host machine, analyzer, blower, finished cyclone separator, pipeline device, motor, etc. The main machine of Raymond pulverizer is composed of frame, air inlet volute, blade, grinding roller, grinding ring, housing and motor. Auxiliary equipment includes jaw crusher, hoist, electromagnetic vibration feeder, electric control cabinet, etc. users can flexibly choose according to the site conditions

I. working principle of Raymond pulverizer:

after the materials are crushed to the required particle size, the materials are sent to the storage hopper by the elevator, and then the materials are uniformly and continuously fed by the vibrating feeder. The stability of quality and other aspects are very important parts of the overall cost; To a certain extent, the brand of the testing instrument is an embodiment of the product market stock and product quality. It is sent to the grinding room of the main machine of Raymond mill. Due to the centrifugal force during rotation, the grinding roller swings outward and presses tightly on the grinding ring. The shovel shovel picks up the material and sends it between the grinding roller and the grinding ring, and the grinding purpose is achieved due to the rolling of the grinding roller. The fine powder after material grinding is brought into the analyzer for sorting with the circulating air of the blower. The fine and coarse materials fall back to the regrinding. The qualified fine powder enters the cyclone powder collector of the finished product with the air flow and is discharged through the powder outlet pipe, which is the finished product. In Raymond grinding room, due to certain moisture in the ground materials, heat generation during grinding, water vapor evaporation, and the lax pipeline interfaces of the whole machine, the external gas is sucked in, which increases the circulating air pressure, so as to ensure that the Raymond mill mill works under negative pressure. The increased air flow is discharged into the dust collector through the residual air pipe, and then discharged into the atmosphere after purification

II. Characteristics and advantages of Raymond Mill:

1. The whole Raymond mill is a vertical structure, which covers a relatively small area and is highly systematic. It can form an independent Raymond mill production system from the rough processing of raw materials to transportation to pulverization and final packaging

2. Compared with other Raymond mills, Raymond machine (Raymond Mill) has a high screening rate of 99%, which is generally not achieved by other milling equipment

3. The transmission device of the main machine of Raymond machine (Raymond Mill) adopts closed gearbox and pulley, which has stable transmission and reliable operation

4. The important parts of Raymond pulverizer are made of high-quality castings and profiles, with fine technology and rigorous process, which ensure the durability of the whole Raymond pulverizer equipment

5. The electrical system adopts centralized control, and the Raymond pulverizer grinding workshop can basically realize unmanned operation, and maintenance

III. operation improvement trend of Raymond Mill:

Raymond mill will mainly develop in the direction of high reliability, energy saving, accuracy, automatic condition monitoring and automatic control in the powder industry. Silicon controlled power supply, AC variable frequency speed regulation, centralized grease lubrication, shock absorption and other measures can be adopted, as well as working condition monitoring and microcomputer automatic control Raymond pulverizer and other devices. Among them, high reliability needs to strengthen the wear resistance of Raymond grinding ring and lower gland through the rationalization research of mechanical principle, and improve the lubrication of Raymond grinding machine before each bearing under continuous working state. Automatic working condition monitoring and automatic control need to add a high intelligent electronic control system in Raymond mill to automatically control the incoming and outgoing of materials, grinding, and dosing. The operator only needs to decompose naturally in the light state, and the button control should be carried out in the operation room. Improving the grinding accuracy of materials requires strengthening the accuracy of the analyzer

IV. use and maintenance of Raymond Mill:

1. During the use of Raymond mill, there should be fixed personnel to take care of it, and the operators must have a certain technical level. Before the installation of Raymond pulverizer, operators must receive necessary technical training to understand the principle and performance of Raymond pulverizer and be familiar with the operating procedures

2. In order to make the Raymond Mill normal, the equipment "Raymond mill equipment maintenance safety operation system" should be formulated to ensure the long-term safe operation of the mill, and necessary maintenance tools, grease and corresponding accessories should be provided

3. After using Henan Raymond mill for a period of time, it should be overhauled. At the same time, it should repair and replace the wearing parts such as grinding roller, grinding ring, blade, etc. to reduce the cost and solve the dust problem. Before and after using 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 grinding device of Raymond mill 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 refueling tools can be used as manual refueling pump and grease gun

5. Raymond Mill fineness adjustment, according to the size, hardness, moisture content and specific gravity of materials, the processing thickness is also different. The analyzer above can be adjusted, with high speed, high fineness, low speed and low fineness. If the fineness is increased, the output will be reduced accordingly. If the requirements are not met, the fan speed should be adjusted, and the user can flexibly master it

6. The remaining minimum wall thickness shall not be less than 10mm for the scrapping limit of the grinding roll and ring of Raymond mill

7. When Raymond mill is stopped, stop feeding first, and the host continues to grind the residual abrasive. After about a minute, turn off the host motor and analyzer motor, stop grinding, and then stop the fan motor, so as to blow away the residual powder

v. development trend of Raymond Mill in powder industry:

with the continuous development of the industry, Raymond mill, as the main grinding equipment in China's powder industry, high reliability, energy saving, accuracy and automation are the inevitable trend of its development

Raymond mills in the powder industry will mainly develop in the direction of high reliability, energy saving, accuracy, automatic working condition monitoring and automatic control. Measures such as silicon controlled power supply, AC variable frequency speed regulation, centralized grease lubrication and shock absorption can be adopted, and devices such as working condition monitoring and microcomputer automatic control are also available. Among them, the high reliability of Raymond pulverizer needs to strengthen the wear resistance of grinding ring, lower gland, etc. through the rationalization research of mechanical principle, and improve the lubrication before the bearings of the machine in the continuous working state

the department heads of relevant units such as the first alumina plant, the second alumina plant, the marketing center, Jinlv Industrial Corporation, the general office, the finance department, the Party committee work department and so on visited the production site. According to the needs of automatic control and automatic control, a high intelligent electronic control system was added inside the Raymond mill to automatically control the incoming and outgoing of materials, grinding, and quantification. The operator only needs to press the button in the operation room to control the raymond grinder. To improve the grinding accuracy of materials, it is necessary to strengthen the accuracy of the analyzer
