A mining vibrating screening machine is a commonly used screening equipment, mainly used to separate impurities in minerals. According to different models, mining vibrating screen machines can be divided into different types, such as:
1. According to the type of motor, the vibrating screen can be divided into linear vibration motor and vibration motor.
2. According to the vibration method, the vibrating screen can be divided vertically and horizontally.
3. According to the type of screen, the vibrating screen can be divided into ordinary screen vibrating screen and stainless steel screen vibrating screen.
According to different models, mining vibrating screen machines’ specific parameters and performance will also differ. Generally speaking, the mining vibrating screen has high screening efficiency, large processing capacity, and long service life and is suitable for separating and purifying various minerals.
The mining vibrating screening machine generally adopts a linear vibrating motor, and the commonly used bearing models are as follows:
1. SKF Bearing: SKF Bearing is a bearing manufacturer from Germany, which is widely used worldwide. Its products are reliable in quality, stable in performance, and widely used in various industrial, commercial, and household applications. Among them, SKF bearings can be used in mining vibrating screening machines to support and drive motors.
2. NTN Bearing: NTN Bearing is also a bearing manufacturer from Japan. It has a wide range of products, including rolling and hydraulic bearings. In the mining vibrating screen machine, NTN bearings are mainly used to support and drive the motor to ensure stable operation of the motor.
3. NSK Bearing: NSK Bearing is a bearing manufacturer from Japan. Its products are famous for their wear resistance and high reliability. In the mining vibrating screen machine, NSK bearings are mainly used to support and drive the motor to ensure stable operation of the motor.
4. FAG Bearing: FAG Bearing is a bearing manufacturer from Germany. Its products are widely used in various industrial, commercial, and household applications. In mine, vibrating screening machines, FAG bearings are mainly used to support and drive motors to ensure the stable operation of the motors.
In addition to the commonly used bearing models mentioned above, some other bearing models can be used in mining vibrating screen machines, such as:
1. INA Bearing: INA Bearing is a bearing manufacturer from Germany. Its products are reliable in quality, stable in performance, and widely used in various industrial, commercial, and household applications. Among them, INA bearings can be used in mining vibrating screening machines to support and drive motors.
2. RHA Bearing: RHA Bearing is a bearing manufacturer from Sweden. Its products are widely used in various industrial, commercial, and household applications. Among them, RHA bearings can be used in mining vibrating screening machines to support and drive motors.
3. SKF BEARINGS Bearings: SKF BEARINGS Bearings is a bearing manufacturer from Germany. Its products are widely used in various industrial, commercial, and household applications. Among them, SKF BEARINGS bearings can be used in mining vibratory screening machines to support and drive motors.
The above are some commonly used bearing models, and the specific selection needs to be selected according to the model of the vibration motor and the application occasion. When choosing a vibrating screen for mine use, in addition to considering the performance and parameters of the equipment, it is also necessary to consider the reliability and stability of the equipment, as well as the maintenance and maintenance of the equipment.
Vibrating screens are used for coarse, medium-fine, and ultra-fine screening materials such as ore and coal. It can also dehydrate materials, desliming medium and other treatments. The self-centering vibrating screen structure mainly comprises a screen box, a vibrator, a suspension (or support) device, and a motor. The motor drives the main shaft of the exciter to rotate through the V-belt. Due to the unbalance on the exciter, centrifugal inertial force is generated to make the screen box vibrate. Different vibration amplitudes can be obtained by changing the eccentric weight of the exciter.
Double exciters drive the linear vibrating screen. When the two exciters rotate synchronously and reversely, the exciting force generated by the eccentric block cancels each other in the direction parallel to the axis of the motor and in the direction perpendicular to the axis of the motor. The stacking is a resultant force, so the motion track of the screen machine is a straight line. The two motor shafts have an inclination angle relative to the screen surface. Under the combined force of the exciting force and the self-gravity of the material, the material is thrown up on the screen surface. It moves forward in a straight line to achieve the purpose of screening and grading the material. It can be used in the assembly line to realize automatic operation. It has the characteristics of low energy consumption, high efficiency, simple structure, easy maintenance, and a fully enclosed structure without dust spillage. The sieving mesh is 400 mesh, which can screen out seven kinds of materials with different particle sizes.
1. High screening efficiency. Due to the strong vibration of the screen box, the phenomenon of material clogging holes is reduced, so the screen has high screening efficiency and productivity
2. The structure of the screen machine is simple and stable, and the maintenance is convenient and quick.
3. Less energy consumption, low noise, and long service life of the screen. Since the center line of the pulley and the center line of the bearing are not on the same straight line, it can eliminate the vibration phenomenon of the belt and reduce the fatigue and wear of the belt so that it increases the vibration amplitude of the sieve, and further improve the productivity.
4. Use the block eccentricity as the excitation force, and the excitation force is strong.
5. Fully enclosed structure, automatic discharge.
