heavy duty vibrating screen with 970 vibrations per minute

Heavy duty vibrating screen can be divided into heavy duty circular vibrating screen and heavy duty linear vibrating screen according to the vibration mode, adapting to the working scene of different particle size and different screening requirements. It has a sturdy structure and strong impact resistance, especially suitable for mining, coal, metallurgy and other industries with high load and high intensity operating conditions, and is an indispensable and important link in the screening of raw materials and mineral processing process.

Features of heavy duty vibrating screen:

1. Adapted to a wide range of particle size:
   Circular vibrating screen: suitable for particle size ≤ 300mm, classification range 3 to 150mm.
   Linear vibrating screen: suitable for particle size ≤50mm, classification range 0.25 to 50mm.
2. A variety of screen mesh can be selected:
   According to the material characteristics, we can choose metal woven screen mesh, rubber screen mesh, polyurethane screen mesh and so on, in order to meet the different requirements of abrasion resistance, corrosion resistance and so on.
3. Adjustable structure design:
   The installation angle of the sieve machine, the installation position of the left and right sides of the motor, and the size of the sieve holes can be customized, with high flexibility.
4. Strong power and large screening capacity:
   With a wide range of screening area (2.88–18 square meters) and motor power covering 5.5–45kW, it can achieve a processing capacity of 20 to 900 tons per hour.

Core advantages of heavy duty vibrating screen:

1. Strong and stable excitation force:
   Driven by block eccentric exciter, it generates strong vibration force to ensure screening efficiency and material handling capacity.
2. Reliable structure, solid assembly:
   The screen box and beam are connected by high-strength bolts to avoid welding stress concentration and improve the life of the equipment.
3. Stable operation and convenient maintenance:
   Equipped with tire-type coupling, flexible coupling absorbs vibration and reduces impulse, smooth and reliable running process, and it is easier to replace parts during maintenance.
4. High quality bearings:
   Standard with SKF or FAG and other international first-class brand bearings, smooth running, high reliability.

Working principle of heavy duty vibrating screen:

1. Heavy duty vibrating screen belongs to single mass forced vibration system. Its main structure includes screen box, vibrator and elastic elements (rubber spring, etc.). The motor drives the exciter through the coupling, so that its internal eccentric block rotates at a high speed, generating a periodic excitation force, which makes the screen box produce continuous vibration.
2. When the material is fed into the screen surface, due to the centrifugal force generated by the vibration of the screen box, the material is thrown up on the screen surface and constantly moving forward, in the process according to the size of the particles to be screened. Smaller than the screen hole of the material through the screen into the lower collection device, the larger particles continue to move forward to complete the screening process.
3. This screening method realizes the automatic layering, penetrating screen and advancing of materials, with high screening efficiency and strong adaptability.

Application areas of heavy duty vibrating screen:

1. Mining industry: used for ore crushing, particle size classification after grinding, replacing the traditional spiral classifier, improve the efficiency of the grinding system.
2. Coal beneficiation plant: It is used for desliming, de-mediaizing and dewatering of fine coal, medium coal and gangue, etc. The grading is accurate and reliable.
3. Metallurgical industry: used in the pre-screening process of ore before steel making to ensure the stability of raw material particle size.
4. Coal industry: used in the screening, grading and cleaning of coal briquettes before processing.
5. Building materials industry: cement, sand and gravel aggregate particle screening, to ensure the consistency of aggregate specifications.
6. Electric power and water conservancy engineering: it plays a key role in raw material transportation of power plant and water conservancy aggregate screening.
7. Chemical and light industry: used for powder, granular chemical raw materials screening operations.
