What Is a Temper Mill?
Stone mill is mainly used for high-fine powder processing of more than 300 materials in some non-flammable and explosive mineral, chemical, construction and other industries. Motor and other components. Users can flexibly use its constituents according to the site conditions. It makes the material finer and easier to divide the labor, which has received a warm welcome in the market.
Stone Mill
- Stone flour mill machinery commonly known
- The structure of the machine (with a schematic diagram of the installation and connection) is mainly composed of a host, an analysis machine, a blower, a finished cyclone, a pipeline device, and a motor. The main unit consists of a frame, an air inlet volute, a blade, a grinding roller, a grinding ring, a cover and a motor. Auxiliary equipment includes jaw crusher, bucket elevator, electromagnetic vibrating feeder, electric control cabinet, etc. Users can choose flexibly according to the site conditions.
- When the Raymond mill is working, the bulk raw materials are crushed to the required feed size, and the materials are sent to the storage bin by the bucket elevator, and then evenly sent to the main engine's grinding chamber by the electromagnetic vibration feeder, and enter The material entering the grinding chamber is lifted up by the shovel and enters between the grinding roller and the grinding ring. The air is blown from the diverter disk into the grinding chamber, and the crushed powder is sent to the analysis chamber. The separation of the rotating analysis impeller, the large particles fall back to the grinding chamber, re-grind, and the qualified fine powder enters the finished cyclone powder collector with the airflow, is separated from the air, and is discharged from the discharge port as the finished product. During the work of the main machine, the blade system played a very important role. It is located at the lower end of the grinding roller. During the same rotation of the blade and the grinding roller, the material is scooped up and fed into the grinding roller roll ring to form a dunnage layer. Crushing to achieve milling purpose.
- 1. In order to make the Raymond mill fine, the "equipment maintenance and safe operation system" should be formulated to ensure the long-term safe operation of the Raymond mill. At the same time, necessary maintenance tools, grease and corresponding accessories must be provided.
- 2. The grinding roller device of Raymond Mill has been used for more than 500 hours. When replacing the grinding roller, the rolling bearings in the roller sleeve must be cleaned. The damaged parts should be replaced in time. The refueling tools can be manually refueled pumps and grease guns. .
- 3. During the use of Raymond mill, there should be fixed personnel to take care of it, and the operators must have a certain level of technology. Before installation of the Raymond mill, the operator must perform necessary technical training to understand the principle and performance of the Raymond mill and be familiar with the operating procedures.
- 4. The Raymond mill should be overhauled after being used for a period of time. At the same time, repair and replace the wearing parts such as the grinding ring and the blade. The grinding device should carefully check the connecting bolts and nuts before and after use. There is looseness, and whether the grease is full.
- The failure of the mill during use can be handled according to the following table.
- Common fault causes and troubleshooting methods
- 1. No flour or less flour. Low yield.
- (1) The powder lock is not adjusted properly, and the seal is not tight, resulting in powder suction.
- (2) The blade wears a lot and the material cannot be shoveled.
- (3) The air duct is blocked
- (4) The leaking seal of the pipeline is not good.
- (5) Check and adjust the seal of the powder locker. A shovel should be used where air leakage is found.
- (6) Replace with a new blade.
- (7) After cleaning the air duct material, re-discharge it.
- (8) Seal the pipeline.
- 2. The finished powder is too thick or too fine.
- (1) The blades of the analyzer are severely worn, and cannot be classified.
- (2) The air volume of the fan is not appropriate.
- (3) Replace the blade length and close the air intake of the small fan to solve the problem of excessive thickness.
- (4) Excessive fineness should increase the volume of imported air.
- 3. The host current rises, the machine temperature rises, and the fan current decreases.
- (1) Excessive feeding, the air duct is blocked by powder, the duct exhaust is not smooth, the circulating current generates heat to make it the main current, the machine temperature increases, and the fan current decreases.
- (2) Reduce the amount of feed and remove dust accumulation in the air duct.
- (3) Open the large residual air pipe valve and control the temperature of the material entering the machine below 6 .
- 4. The host is noisy and has large vibration.
- (1) The feeding amount is small. The blade is severely worn and cannot shovel material, and the anchor bolts are loose.
- (2) Hard impact is large, or there is no material layer
- (3) The out-of-round deformation of the grinding ring is severe.
- (4) Adjust the feed amount and replace with a new blade.
- (5) Change the feed size.
- (6) Replace the grinding roller and grinding ring.
- 5. Fan vibration.
- (1) Powder accumulation or uneven wear on the blades.
- (2) Loose anchor bolts.
- (3) Remove powder from the blade or replace the blade.
- (4) Tighten the anchor bolts.
- 6.Transmission device and analysis engine oil tank is hot
- (1) The oil viscosity is large and the oil thickness is too high, and the threaded pump oil cannot be used to make the upper bearing lack of oil.
- (2) Check whether the grade and viscosity of the engine oil meet the requirements.
- (3) Check the running direction of the analyzer
- 7. The grinding roller device feeds into the bearing damage cup.
- (1) The oil is cut off or the seal is damaged.
- (2) Long-term lack of maintenance and cleaning.
- (3) Refuel in time according to the stipulated time.
- (4) Regularly clean and replace the oil seal.
- The maintenance of the machine is an extremely important recurring task. It should be closely coordinated with extreme operation and maintenance. Full-time personnel should perform on-duty inspection.
- 1. Installation test run:
- 1. The equipment should be installed on a horizontal concrete foundation and fixed with anchor bolts.
- 2. Please pay attention to the vertical of the main body when installing.
- 3. After installation, check whether the bolts in all parts are loose and whether the main engine compartment door is fastened. If so, tighten it.
- 4. Configure the power cord and control switch according to the power of the device.
- 5. After the inspection is completed, perform a no-load test run, and the test run can be carried out normally.
- Maintenance of the machine:
- 1. The shaft bears the full load of the negative machine, so good lubrication has a great relationship with bearing life. It directly affects the service life and operating rate of the machine. Therefore, the injected lubricant must be clean and the seal must be good. Main oiling places (1) rotating bearings (2) roller bearings (3) all gears (4) movable bearings, sliding planes.
- 2. The newly installed rims are prone to loosening and must be checked frequently.
- 3. Pay attention to whether the parts of the machine work normally.
- 4, pay attention to check the wear degree of easy-wearing parts, pay attention to replacing worn parts at any time.
- 5. The plane of the bottom frame of the movable device should be out of dust and other materials to prevent the movable bearing from moving on the bottom frame when the machine encounters unbreakable materials, resulting in serious accidents.
- 6, bearing oil temperature rise, should immediately stop the inspection to eliminate the cause.
- 7. If there is an impact sound when the gear is turned, it should be stopped immediately for inspection and eliminated.
