Rotary Flat Sieve vs Vibrating Sieve in Feed Industry

Basic Working Principle

 
Rotary Flat Sieve
 
It runs with horizontal circular and gradual reciprocating motion on the sieve surface. Materials spread evenly and move slowly without strong vertical impact. The screening process is gentle and stable.
 
Vibrating Sieve
 
Adopts high-frequency 3D vibration drive. Materials jump and move forward quickly on the sieve deck. The movement is fierce with obvious vertical shaking force.
 

Main Differences in Feed Production

 
  1. Screening Accuracy
     
    Rotary flat sieve: High precision, uniform particle grading effect.
     
    Vibrating sieve: Medium accuracy, suitable for rough separation.
     
  2. Particle Breakage Rate
     
    Rotary flat sieve: Extremely low breakage rate, perfect for fragile feed pellets.
     
    Vibrating sieve: Relatively high breakage rate, easy to damage soft pellets.
     
  3. Production Capacity
     
    Rotary flat sieve: Medium output, stable running for fine screening.
     
    Vibrating sieve: Large processing capacity, ideal for mass production.
     
  4. Screen Mesh Blocking
     
    Rotary flat sieve: Low clogging rate, good self-cleaning effect for oily and fine powder materials.
     
    Vibrating sieve: Easy to block when dealing with high-oil and sticky feed raw materials.
     
  5. Noise & Foundation Requirement
     
    Rotary flat sieve: Low noise, small vibration, no strict reinforced foundation needed.
     
    Vibrating sieve: High noise and strong vibration, requires firm equipment foundation.
     
  6. Maintenance & Cost
     
    Rotary flat sieve: Higher equipment cost, longer service life of sieve mesh.
     
    Vibrating sieve: Economical price, simple structure, easy screen replacement.
     
 

Application Scope in Feed Industry

 

Rotary Flat Sieve Application

 
  • Aquatic feed such as fish feed and shrimp feed
  • Young animal feed including piglet feed and chick feed
  • High-grade pet feed and premix feed
  • Fine grading after secondary crushing of raw materials
  • Dust-free and high-standard feed production line
 

Vibrating Sieve Application

 
  • Conventional livestock and poultry bulk feed
  • Primary impurity removal of corn, soybean meal and bran
  • Rough classification after pelletizing process
  • Large-volume ordinary feed processing projects
  • Coarse separation of heavy feed raw materials
 

How to Choose

 
Choose Rotary Flat Sieve if you need high grading precision, low pellet damage and produce high-end feed products.
 
Choose Vibrating Sieve if you pursue large output, low investment cost and mainly produce common bulk feed.
