    Solid pump for plastic grinding.

    i have come acrooss something called a peristaltic pump.Any idea whether these could pump plastic slurry?In fact I just started another thread on these.

    Solid pump for plastic grinding.

    Bimr,conventionally it's done in a horizontal tank and rotating screens are used to get rid if dirt at initial stages.I was trying to see if it could be done more efficiently in some non conventional way.Compositpro, the required input is dry plastic grinding of bulk density approx 0.5kg per...

    Yes Artisi, A floating pump with one of the impellers which Mike suggested should work.Thanks a ton.

    Solid pump for plastic grinding.

    Artisi,a sort of slurry could be made having more plastic and less water.This would go into the hopper and hopefully be carried with the water.

    Solid pump for plastic grinding.

    Artisi, Pneumatic injection might be a way but easier said than done.AThe pressure at the bottom will be quite a bit.Are there any pumps which can handle solids?I would appreciate any links to their details.WCompositepro, is there any link which might give some idea about how its done.

    Solid pump for plastic grinding.

    Thank you for replying.The material is grinding of polypropylenpe which floats on water.The material would be injected at the bottom and cleaned of contaminants while it rises and would be taken out in the overflow from the top.I haven't done this before but was trying to work out how this...

    Solid pump for plastic grinding.

    I want to continuously transfer plastic grinding of size approx 5 mm into the base of a water collumn about 10 feet height and dia 5 feet continuously.I would be grateful if someone could guide me as to how this be accomplished.

    Fruits Waste Grinding/Pulverizing

    I grind plastics.The grinder consists of three rotating blades and four stationary side blades with a mesh at the bottom to determine which size drops out.Would such an arrangement help?

    sludge formed while attempting to neutralise caustic

    The Plastic grinding was of bottle cap coming from a plant which crushes and washes and reclaims PET from PET bottles.The caustic was a remnant.I was trying to reclaim the plastic.The water used was tap water.The sludge did not seem to be oily.

    sludge formed while attempting to neutralise caustic

    while washing plastic scrap grinding I tried to neutralize the caustic present in it with HCl.The addition of HCl caused a grey sludge which would float to the top leaving clear water below.I had thought that the resulting NaCl would be soluble in water and not create a problem but the floating...
