    Conveyor belt cleaning techniques

    Paddy Sorry for just seeing your post. Is the roller brush driven independent of the conveyor belt or are you relying on the belt to rotate the brush? If not, ensure that the brush runs faster then the belt surface speed Is the brush contra rotating to the belt travel? Has the brush got a spiral...

    Conveyor Belt Question

    The "Theory" of handling product on a roller conveyor is to have the roller pitch so that the centres of three consecutive rollers is equal to the product length, in your case with the 4" dia product, the centres between each adjacent roller needs to be 2", so that the distance from roller (1)...

    Can anyone tell me how to remove this object from my motor shaft?

    Jpn5 For your information, this "brand" of motorised gearbox (Bonfiglioli, STI,etc) are made in Italy, and have a hollow output arrangement. If you remove the bolt on the opposite side to the bush, you should be able to remove the whole shaft from the output, which make it free for you to do...

    Brisbane, Australia -- Pressure vessel mfgrs in or near

    Metman what are the approx physical dimensions of the vessels you require-you may get a better price out of Sydney (business is pretty slow here in Sydney at present), freight may be the killer though. I could get some freight estimates if you want. Ross

    conveyor belt - fertlizer bag coefficient of friction

    chumet Many factors come into play, bag material, speed, conveyor design etc My Gut feel is that "old" coal plant belts will not work. A static test will not prove anything, as you require the dynamics of movement to get a true result. There are speciality belts available that will succeed at...

    Help with motor and gearing

    Hi Mr Ridley Firstly, you need to advise the means of driving this conveyor. I assume from your notes that the existing rollers are 2.75", but how do you intend to impose drive to these rollers(Chain, vee belt, timing belt, flat belt etc) as this will then determine the best means. So far your...

    Lotus Twin Cam .120" oil orifice...pinging Rod;

    Dumb question-what oil pressure is he getting? I am happy to defer to the experts above, but "normal" oil pressure for the standard Kent engine is 40 psi. My twin cam runs 35/45 psi and talking to more knowledgable persons than I, the consensus is volume is more important than pressure. Chasing...

    how to calculate the belt conveyor gear motor power

    A good estimation is: Total load on belt(pounds) x friction factor x belt speed (in feet per minute)/33000 = HP Ross

    Torque to load in conveyor application

    Hi Caveman Jones Below is the details of what I was trying to say "The torque arm concept is the most preferred, since it enables a hollow shaft reducer to hang from a solid shaft and to be totally supported by that shaft. A torque arm is simple to install and guards against potential...

    Torque to load in conveyor application

    Hi Caveman I think your SEW rep should have another think about what he said: ""dont recommend putting reducers between bearings because of the shafts not being perfectly straight."" If it sitting on the shaft it must be straight-the flexible mount within the torque arm will take up any...

    Torque to load in conveyor application

    Hi Caveman I have come into this discussion a bit late. However, we build many conveyors in a given year using SEW and other brand hollow shaft gearmotors with torque arm mounting. I surmise that this application is for a lift up transfer in a pallet handling system and would guess that the...
