The main types of vibrating screens:
Mainly divided into linear vibrating screen, circular vibrating screen, rotary vibration sieve, vibrating vibrating screen
Then the vibrating screening device has those and the specific classification?
Vibrating screening equipment by weight can be divided into: mining vibrating screen, light fine vibrating screen, experimental vibrating screen machine
Mine vibrating screen can be divided into: high-performance heavy sieve, custom center vibrating screen, oval vibrating screen, dehydration sieve, round sieve, banana sieve, linear vibrating screen
Light fine vibrating screen can be divided into: rotary vibration sieve, linear sieve, straight sieve, ultrasonic shaker, filter sieve can refer to shaker series
Experimental vibrating screen: slap sieve, bumper-type vibrating screen machine, the standard test sieve, electric vibrating screen, etc. Please refer to the experimental equipment
Of course, this classification is not the most scientific, it was suggested that according to the vibrating screen material trajectory classification, I simply do under the reference only:
According to the linear motion trajectory points: linear vibrating screen (material on the screen surface to do straight forward movement)
According to the circular motion trajectory points: round sieve (material in the screen surface to do circular motion) Structure and advantages:
Mechanical classification
Vibrating sieve is mainly divided into linear vibrating screen, circular vibrating screen. The vibrating screen may be of the type of vibrator
Divided into uniaxial vibrating screen and biaxial vibrating screen. Uniaxial vibrating screen is the use of single unbalanced excitation to make the screen box vibration, sieve surface tilt, sieve box trajectory is generally round or oval. The biaxial vibrating screen is a double unbalanced heavy excitation using synchronous orifice rotation, the horizontal or gentle inclination of the screen surface, and the trajectory of the screen box is straight. Vibrating screen with inertial vibrating screen, eccentric vibrating screen, custom center vibrating screen and electromagnetic vibrating screen and other types.
Linear vibrating screen
When the vibrating screen is working, the two motors are placed in the reverse direction to cause the exciter to produce the reverse exciting force, forcing the sieve body to drive the screen to do the longitudinal movement, so that the surface of the material by the exciting force and periodically throw a range forward, Thus completing the material screening operation. Linear vibrating screen (linear sieve) has the advantages of stable and reliable, low consumption, low noise, long life, stable vibration and high screening efficiency. It is a kind of high efficiency new screening equipment, widely used in mining, coal, smelting and building materials , Refractories, light industry, chemical and other industries.
Circular vibrating screen
Circular vibrating screen (circular vibrating screen) to do circular motion, is a multi-layer, efficient new vibrating screen. The circular vibrating screen adopts the cylindrical eccentric shaft exciter and the offset block to adjust the amplitude, the material sieving line length and the screening specifications are many, the structure is reliable, the exciting force is strong, the screening efficiency is high, the vibration noise is small, the rugged and the maintenance Convenient, the use of safety and other characteristics, round sieve is widely used in mining, building materials, transportation, energy, chemical and other industries product classification. Circular vibrating screen mainly screen box, screen, vibrator, vibration spring device, chassis and other components. Vibrator on the side of the screen box, together with the motor through the coupling or belt rotation, resulting in centrifugal inertia force, forcing the screen box vibration. Screen is the main wearing parts. According to the material products and user requirements, can be used high manganese steel braided mesh, punching sieve and rubber sieve plate, sieve plate with a single layer and double two, all kinds of sieve can meet the different requirements of screening effect. The series of circular vibrating screen for the seat installation. The adjustment of the inclination of the screen surface can be achieved by changing the height of the spring seat position.
Stone drum sieve
Roller sieve is made of hexagonal drum, rack, funnel, reducer, motor five parts into. Broken stone into the drum, on the one hand with the drum rotation was screened by the rotation of the cylinder centrifugal force and jigging to screen the material. On the one hand the large size of the stone along the inclination of the drum forward, through the different mesh screen gradually screened out. The small stone is sieved into the respective funnel and then transported by hand or by gravity to the finished pile. Its structure is simple and reliable, smooth operation, with good sealing, no pollution, small noise, fast change, fine grading, sorting ratio, high yield, sorting accurate, low failure rate, easy maintenance, especially for sand Stone field grading use. Drum sieve fine workmanship, durable, steel frame to steel welding, funnel volume, made of steel plate. There are five funnels separately. Funnel mouth to flange connection, can be on both sides or side of the material, easy to pull or gravity, to improve the production, to prevent blocking wear and tear screen, delay production.
Advantages of vibrating screens
Mainly by the screen box, exciter, suspension (or support) devices and motors and other components. Motor by the V-belt,
Driven by the exciter main shaft rotation, due to the exciter on the uneven weight of the centrifugal inertia force, so that the screen box vibration. Change the exciter eccentric weight, can get different amplitude.
The main advantages of vibrating screen:
1, because the screen box vibration is strong, reducing the phenomenon of material clogging the sieve, so that the screen has a high screening efficiency and productivity.
2, simple structure, easy to replace the screen surface.
3, the screening of tons of material consumed by less energy.
