The internal grinding device of the Raymond Mill Machine adopts overlapping multi-stage sealing, which ensures smooth transmission and reliable operation.4. The core part of the Raymond Mill Machine uses wear-resistant parts to extend its service life and reduce subsequent maintenance costs.三、Maintenance1. Why is the grinding roller and ring of the Raymond mill easily worn?The grinding roller device is mainly used for grinding materials. It is a component that directly contacts the material, so it is often easily damaged and requires regular maintenance. How to reduce maintenance costs? It is necessary to add engine oil within the specified time, and pay attention to the hardness and particle size of the grinding material to reduce the friction between the grinding roller devices. Of course, if the grinding roller is seriously damaged, it must be replaced in time.2. Maintenance of Raymond Mill Machine accessories(1) If the grinding roller and ring are used for more than 500 hours, the grinding roller sleeve must be replaced.(2) The bearings and bearing chambers must also be cleaned to ensure appropriate clearances.(3) When the host machine is running, unplug the power supply if something goes wrong.

Raymond mill is a common industrial equipment used to grind a variety of materials. However, sometimes we may encounter the problem of low production of Raymond mill, which will not only affect the work efficiency, but also increase the production cost. Here are some ways to solve the low yield of Raymond mill:1. Adjust the feed amountThe yield of Raymond mill is directly related to the feed quantity. If the feed amount is too little, the ground out of the material is insufficient, resulting in low output. If the amount of feed is too large, it will increase the risk of energy consumption and equipment damage. Therefore, we need to adjust the feed amount according to the specific situation to find the best production efficiency.2. Replace the grinding roller and ringThe roller and ring are the core parts of Raymond mill, and if they are worn or damaged, it will lead to low production. Therefore, regular inspection and replacement of rolls and rings is the key to maintaining a stable Raymond mill yield.3. Adjust the wind speed and volumeWind speed and air volume are important factors affecting the production of Raymond mill. If the wind speed and air volume are not appropriate, it will cause the material to stay in the mill for too long or too short, affecting the grinding effect. Therefore, we need to adjust the wind speed and air volume according to the specific situation to obtain the best production efficiency.4. Clean the dust collector and pipesThe dust collector and pipe of Raymond mill may accumulate dust and materials due to long-term use, resulting in poor ventilation and affecting the yield. Therefore, we need to clean the dust collector and pipe regularly to ensure smooth ventilation and maintain the normal working condition of Raymond mill.In short, it is very important to keep the output of Raymond mill stable, which requires us to take corresponding measures according to the actual situation. In addition to the above methods, there are many other ways to improve the output of Raymond mill, we need to choose the appropriate method according to the specific situation to achieve the best production efficiency.
Raymond mill in the process of use, there may be rust. This is mainly due to the following reasons:Cause one: The humidity is too highIf the Raymond mill is in a humid environment for a long time, it is prone to rust. Therefore, during use, try to avoid putting it in a wet place.Reason two: Lack of maintenanceIf it is not maintained for a long time, the surface of the mill is prone to oxidation, resulting in rust. Therefore, in the process of use, it is necessary to carry out regular maintenance of the mill, including cleaning and applying anti-rust oil.Reason three: improper useIf the grinding machine is not used and stored correctly, it will lead to scratches and wear on the surface, thus accelerating the rust process.So, when there is a Raymond mill rust, how should we deal with it?Treatment method one: Clean the surfaceIf there is slight rust on the surface of the mill, you can use detergent and wire brush to clean, remove the rust, and apply a layer of anti-rust oil on the surface.Solution 2: Replace the partsIf there is more serious rust on the surface of the mill, it is recommended to replace the parts with more serious rust, so as not to affect the normal use of the mill.Treatment method three: regular maintenanceIn order to avoid the rust of the mill, we should carry out regular maintenance on it. Specific operations include: clean the surface of the mill, apply anti-rust oil, check the wear of parts and so on.In short, the rust problem of Raymond mill can be avoided. As long as we pay attention to maintenance and use during use, we can ensure its normal operation and extend its service life.
Pendulum mill is a commonly used grinding equipment, widely used in chemical, food, pharmaceutical and other industries. It adopts the principle of swinging motion to grind the material in the mill, so as to achieve the purpose of crushing.Working principlePendulum mill is composed of grinding disc, swing arm, transmission device, motor and other parts. The motor drives the swing arm to do reciprocating movement through the transmission device, so that the materials in the grinding disk are rubbed and ground in the grinding disk, and finally crushed into the product of the required particle size.The characteristic of the pendulum mill is that the central axis of the mill disc and the axis of the pendulum arm are not in the same plane, so in the operation process, the pendulum arm is not only to do simple reciprocating motion, but also to drive the corresponding rotating motion of the mill disc. This design can not only improve the crushing efficiency, but also reduce the residence time of the material in the mill, and avoid the problem of excessive crushing of the material.Scope of applicationPendulum mill is suitable for crushing a variety of brittle materials, such as hard, brittle chemical raw materials, food raw materials, pharmaceutical raw materials and so on. Its advantages of high crushing efficiency, low energy consumption, less dust, and low noise make it an essential equipment for chemical, pharmaceutical and food industries.Matters needing attentionDuring the operation of the pendulum mill, attention should be paid to regularly check the lubrication of the transmission device, bearings and other parts to ensure the normal operation of the equipment.Operators should use the equipment in accordance with the operating procedures to avoid personal injury and equipment damage.When cleaning the device, stop the power supply and wait for the device to stop completely before cleaning and maintaining the device.In the process of use, if there is an abnormal phenomenon, it should be stopped in time for inspection and troubleshooting to ensure the normal operation of the equipment.In summary, pendulum mill is an efficient and reliable grinding equipment, its unique working principle and superior performance, so that it is widely used in chemical, pharmaceutical, food and other industries. In the process of use, we should pay attention to the maintenance and maintenance of the equipment to ensure its long-term stable operation.
"Quality first and customer first" is our eternal service tenet. "Integrity-based" is our corporate morality.
