YK Series Vibrating Screen

YK Series Vibrating Screen

YK Series Vibrating Screen, also known as the vibration screen, is widely used to separate materials into various sizes for further processing. Vibrating screen is used as a support machine stone crushing plant, or end use, of course, it depends on the needs of customers. Material separation by it by vibration screen box, there are many different size of screen, or grid, the material failure like a sieve, windrow of additional material conveyor of the final product.The final product can be used for building and construction industry.

Detailed Introduction

Vibrating screen is a wet fine-grained difficult to sieve material dry sieving of the vibrating screening machinery and equipment, is currently the domestic processing of difficult screening materials, vibration screening machinery and equipment. The vibrating screen has the characteristics of large amplitude, large vibration intensity, lower frequency and elastic sieve surface. The work process has always maintained the maximum opening rate, so high screening efficiency, processing capacity, easy to replace the screen, reducing the cost. Vibrating screen large screen surface and large processing capacity to meet the production needs of the scene. The structure of the vibrating screen sieve adopts multi-section sieve surface vibration and the screen box and the frame do not participate in the vibration movement mode, so that the sieve can realize the large-scale.

Technical Features And Advantages

  • 1. High capacity and reliability.
  • 2. High screening efficiency.
  • 3. Long bearing lifetime.
  • 4. Easy maintenance.
  • 5. Pivoting motor bases.
  • 6. Special eccentric shaft create circular throw action.

Classification Of Vibrating Screen

Vibrating screening equipment by weight use can be divided into: mine vibrating screen, light fine vibrating screen.

Experimental vibrating screen Mine vibrating screen can be divided into: high-performance heavy sieve, self-center vibrating screen, oval vibrating screen, dehydration sieve, round sieve, banana sieve, linear vibrating screen.

Light fine vibrating screen can be divided into: rotary sieve, linear sieve, straight sieve, ultrasonic shaker, filter screen can refer to the shaker series.

Experimental vibrating screen: slap sieve, bumper type vibrating screen machine, standard test sieve, electric vibrating screen, etc. Please refer to the experimental equipment.

According to the linear motion trajectory points: linear vibrating screen (material on the screen surface to do a straight forward movement).

According to circular motion trajectory points: round sieve (material in the screen surface to do circular motion)

The Working Principle Of Vibrating Screen

Vibrating screen work, the two motor synchronous reverse rotation so that the exciter to produce reverse exciting force, forcing the sieve to drive the screen to do vertical movement, so that the material on the exciting force and cyclical forward throw a range, Thus completing the material screening operation. Suitable for quarry screening sand and gravel material, but also for coal preparation, mineral processing, building materials, power and chemical industries for product classification. The working part of the vibrating screen is fixed and the material is sieved along the working surface. Fixed grid sieves are more widely used in concentrates, and are generally used for pre-screening before shredding or shredding. It is simple in structure and easy to manufacture. Do not consume power, you can directly unload the ore on the screen surface. The main drawback is the low productivity, low screening efficiency, generally only 50-60%.

Vibrating screen work surface is a horizontal arrangement of a root rolling axis, the axis of a plate, fine material from the roller or the gap between the plate through. The bulk material is driven by the roller to the one end and discharged from the end. Concentrators often use this sieve. The working part of the vibrating screen is cylindrical, the whole screen is rotated around the axis of the cylinder, and the axis is not inclined in the general situation. The material is fed from one end of the cylinder and the fine grade material passes through the sieve of the cylindrical working surface and the coarse material is discharged from the other end of the cylinder. The speed of the cylinder screen is very low, work smoothly, the power balance is good. But its sieve is easy to plug, the screening efficiency is low, the working area is small, the productivity is low. The concentrator rarely uses it for screening equipment. The vibrating screen body is a plane swings or vibrations. According to its plane motion trajectory is divided into linear motion, circular motion, elliptical motion and complex movement. Shaking sieve and shaker are of this category. When the vibrating screen is working, the two motors are placed in reverse direction to cause the exciter to generate the reverse exciting force, forcing the sieve body to drive the screen to do the longitudinal movement, so that the material on the excitement and cyclical forward throw a range, Thus completing the material screening operation. The shaking sieve is a crank link mechanism as a transmission part. The motor through the belt and pulley drive eccentric shaft rotation, by connecting rod so that the body in a certain direction for reciprocating motion. The direction of movement of the body perpendicular to the strut or suspension rod center line, due to the body of the swing movement, so that the material on the screen surface to a certain speed to the discharge end of the material at the same time be sifted. The shaking sieve has a higher productivity and sieving efficiency than the above sieves. The disadvantage is poor power balance. Now the concentrator rarely use it, and the structure is more reasonable to replace the shaker.
