Hello, i want to ask about trommel screen, i had a project to design a trommel screen, but i so confused about the principal to make a trommel screen design, i dont find a principal on internet, if anyone have a book/pdf about that, please share the link below. in picture below is my example design with : 

  1. incline 4degree
  2. size = ID 2250 x 1000 L
  3. capacity = 300 t/hr
  4. rpm = 8.5
  5. drive unit = motor 75 kw+chain drive+Gear reducer

my trommel screen have divided by 3 mesh material

  1. 407 -323 mm
  2. 323-224
  3. 224 - 150

and material from jaw crusher feed is 

  1. 407 -332 (26,67%)
  2. 323-224 (35,33 %)
  3. 224 - 150 (7,83%)
  4. the rest of it is material over 407

my question is, what the basic theory to determine length of mesh based on material feed from jaw crusher? or my picture had good design for trommel screen? please anyone comment anything.
