How to extend the service life of double stage wet-grinding mill rotor bearings

Huasheng Ming Heavy Machinery Co., Ltd. produces two-stage wet material crushers with high quality, low price, simple operation and strong practicality. Low power, high output. The gangue granules smashed by our two-stage wet material crusher produced by Huashengming Heavy Industry Machinery Plant are small and smaller than the granules crushed by the traditional single-stage crusher. It is basically 2mm. No tumbler and shaker are needed. The most important thing is that there is no smashing at the bottom of the screen, and it can be normally produced on rainy days without being affected by the weather. The crushed material of the two-stage wet material pulverizer can be used to make sintered bricks, burning bricks without fuel, saving energy, reducing the use of land for bricks, saving land resources, turning waste into treasure, reducing environmental pollution, and being well received by customers. Pro-gaze, more customers invest in two-stage wet crusher, mining machinery and equipment, many crusher equipment will have consumables. The two-stage wet-grinding mill requires a longer life for these consumable parts, rotor bearings:
1. Select the correct type of rotor bearing. The double-row radial spherical roller bearing has the advantages of strong bearing capacity and good aligning performance, so this type of bearing is often used as a rotor bearing when selecting. In addition, the calculated life of the selected bearing should be 5000 ~ 10000h.
2. To improve the mechanical conditions of the crusher bearings. The impact load acting on the bearing depends on the impulse acting on the rotor and the bearing support's support flexibility. Increasing the bearing support flexibility will reduce the impact load on the bearing. For this purpose, we can add a rubber plate of appropriate thickness between the bearing housing and the support frame to improve the bearing support flexibility.
3. To improve the balance of the rotor accuracy. The wet mass of a two-stage wet-grinding crusher has a large mass and a high rotational speed, and the casting deviation of the rotor body and the mass deviation caused by the installation of the hammer of the plate will cause an unbalanced centrifugal force when the rotor rotates.
4. Reasonably adjust the cooperation relationship between each other. The rotor bearing of a two-stage wet-grinding mill is mainly subjected to impact loading during operation, and the load on the rolling elements is not the same. The rolling element subjected to the combined action of the impact load has the highest stress, and the inner and outer ring raceways are also the same. The maximum force is applied here in contact with the rolling element.
Huashengming Heavy Duty Wet Material Mill has its own place in the current market in the development of refinement. With superb production technology, the production efficiency of the equipment has been a qualitative leap. At the same time, improve the company's position in the economy, and better provide different customers with comprehensive technology and first-class equipment, we Huasheng Ming Machinery Factory all the staff will wholeheartedly serve you in the end. 24 hours telephone number

Aluminum Spiral High Speed Door

The Spiral door offers high-speed operation for high-traffic situations and rigid aluminum slat construction that eliminates the need for a second security door. Crisp lines give the Spiral door a stylish look that's great for many types of commercial, automotive retail, government, institutional and industrial applications. The Spiral is ideal for automotive dealerships, government, parking and security. Benefits No metal-to-metal contact reduces wear on the door panel and offers fast, quiet operation.

Aluminum spiral High Speed doors are usually used wherever goods traffic occurs and where the doors have to fulfill special requirements. In the food and beverage industry, or Medical industry for example, special climatic conditions have to prevail; short opening and closing times reduce cooling loss, avoid airflow and enable a smooth operating procedure. They can also be designed in larger dimensions for the mining and aircraft industries.
