Calculate power of blending

  1. May 15, 2018 #1
    Hello pleas i need help how to calculate needed power(of engine) for blending granual material in machine.
    Machine looks like on pic below
    thank you

    Welcome to the PF.

    For us to be of any help, we will need lots more information. How big is this machine? What exactly is the material being blended? How much material at a time is put into the machine? Do other similar machines exist, and if so, what size electric motor do they use?

    it have to have capacity about 600-700dm3... the material will be trash of electric components so it is hard to tell :) density is probably about 500kg/m3 at one time we put in machine about 300kg :) we have same machine but for blending coal ash and it have capacity about 40dm3 and engine power is 0.18kw

    So this is a shredder, not a blender?

    nono :) it will be like homogenizator :)

    Those two statements make no sense in juxtaposition, IMO. What the heck are you trying to make? o0)

    i need to make mashine what will make sample of trash to know what type of pieces i have in :biggrin:
     
  9. May 16, 2018 #8
    so i need to blend trash :O to homogenize it :) and the take it out that is why i wanna use paddles :)

    1. Does this capacity of 40dm3 mean 40 cubic decimeters?
    2. Is this the amount of material than fits into the mixing/processing chamber? Or is this the volume of material that can be processed within a set period of time (i.e. - 40 dm3/hour)?

    yea cubic decimeters :) and it is in one time :)so mixing all material
     
  12. May 16, 2018 #11
    so i need to mixing all 300kg in one mixing process :)

    More detail, please. As you may imagine, it takes considerably more power to chew through a scrapped 10 HP induction motor than it does to process a batch of circuit boards.

    it is brash of electric components ... it can contain everything :) but size of components is about 50x50x50mm :) as i told density of material is about 500kg/m^3

    i know it is bad situation :/

    If you mash up electronics circuit boards, you will destroy the components. Is that you want? Also, some components release chemicals when smashed up (like electrolytic capacitors), and those chemicals can cause other problems. What is your end goal with this "blender"?

    :DD ok it is just blender :) it is filled with trash after milling :) so i dont care about types of components :) i just need to blend mass of electric components trash (like rubber, elektric circuits, metal fragments) this trash have pieces of size about 50mm :)

    For what purpose? Usually you would want to separate things for recycling, not "blend" them all up.

    to make homogenized sample :)
     
  20. May 16, 2018 #19
    this device have split filled matterial to sample and trash :) and every piece of filled material have to have same chance to be in sample (sorry for bad neglish) O:)

    Sigh. That makes no sense. Are you an artist or something? I see no practical use for this process.
