Crusher bearing some skills must know

Fine crushing machine, also known as high efficiency crusher, third generation fine crusher and so on. The machine has a wide range of uses and its performance has reached internationally outstanding level. It is a proven, practical and reliable crushing machine and is particularly suitable for the production of abrasives, refractory materials, cement, quartz sand, steel sand, slag powder, copper ore, The fine crushing and smashing of various hard and brittle materials such as iron ore, gold ore, concrete aggregates, and asphalt aggregates is an efficient and energy-saving gravel sand making equipment, which is 50% more energy efficient than conventional crushers and is currently The world's advanced crusher equipment.

In order to ensure the stable operation of gravel production line equipment, it must pay attention to its daily maintenance, especially the lubrication of the core component bearings.

The bearing lubrication of the crusher directly affects the operation of the entire production line. The choice of bearing grease directly relates to the stable operation of the equipment. In order to better play the excellent status of the bearing, the selection of bearing lubricants for the cobblestone crusher is introduced.

1. Anti-rust performance: The grease used in the bearing must have anti-rust effect, and the anti-rust agent can be insoluble in water. Grease should have good adhesion and can form a film of oil on the surface of the steel.

2. Mechanical stability: Grease can become soft during machining and cause leakage. During normal operation, grease will be thrown from the bearing housing into the bearing. If the mechanical stability of the oil is not sufficient, during the operation, the soap structure of the oil will mechanically disintegrate, causing the oil to be destroyed and thus lose its lubricating effect.

3, oil seal: oil seal is necessary to protect the bearing and lubricant from the outside pollution barrier, the bearing operation process, regardless of debris or moisture can not penetrate the bearing to prevent damage to it. Sand making machine price, cone crusher, crusher, etc. are the main mineral processing equipment and crushing equipment on the market. Proper installation and maintenance is an important factor in the long service life of the bearing. At the same time, attention must be paid to the cleanliness of bearings, the correctness of bearing selection and the selection of appropriate installation and maintenance tools. In addition, the bearings must be protected from contamination and moisture, and they must be properly installed and lubricated.

4. Mixed oils: Never mix incompatible oils. If two incompatible oils are used, the consistency of the two oils will become soft, and the bearings may be damaged due to the loss of grease. If you do not know which type of grease was originally used in the bearing, you must remove the old grease inside and outside the bearing before adding new grease.

5, the classification of grease: mainly based on temperature and working conditions to distinguish: grease can be classified according to their permissible operating temperature, grease consistency and lubrication capacity is affected by the working temperature, the bearing must be selected to operate in a certain temperature At the same temperature, it has the correct consistency and good lubrication effect. Greases are manufactured in different operating temperature ranges and can be roughly classified into greases for low, medium and high temperatures. At the same time, there is a type of grease called extrusion-resistant or crush-resistant and added with molybdenum disulfide. At the same time, additives are added to enhance the strength of the lubricant film.

6, select the important factors of oil: If the wrong choice of grease is all measures to prevent bearing is futile, choose a grease, its base oil viscosity at the working temperature is to provide sufficient lubrication effect is very important, the viscosity is mainly affected by temperature The effect of it decreases with increasing temperature, and it rises when the temperature drops. Therefore, it is necessary to know the base oil viscosity at the operating temperature.
