This is a radial stacker supported by four steel wheels. This particular wheel will have the drive directly connected to it. The total weight (wind, snow, live load, dead load) seen on the steel rail is 224,000 pounds or 56,000 pounds per wheel. My assumption is it will take 4 seconds to...
I have a chain conveyor with flights that handles various products. The take-up is done with hydraulics but the environment is too harsh. I want to build a take-up that is less forgiving. The hydraulic system, when working, either over slacks or breaks chain. If I get a piece of rebar...
I have a stacker wheel truck to rebuild. the space is tight. I need options besides press fit. I may be able to get a key in but there is no hub to speak of and thus set screws are out of the question. the wheel is driven so i need a positive way to tranmit the prime mover to the wheel. a...
is there a way to show the leading zero when the cell is fomated for a number (eg 00425 entered in a cell and excel returns it as 425). I don't want to make it a text with a '00425.
using the values in column 1 and column 2 to select a unique row and a value in row one to return a single number
example input column 1 = 12 / input in column 2 = 3 / input to row 1 = 38 would return 125
0 0 20 26 32 38 44 51
10 2.50 60 75 85 100 110 120
10 3.50 75 85 95 110 120 130
12 2.50...
I have a 10" screw conveyor moving cement from a silo to a weigh batcher. I want to incline the screw conveyor and increase the rpm to make up for the lost volume caused by the incline. I can find the formulas for friction and material horsepower in the horizontal condition but nothing on the...
I have a structure in a 4 zone. The structure is a basic building structure with concrete making bins inside. It is an open structure with bracing and platforms. At the top of the structure is a large collar beam that supports 3 silos. Do I have to use the r value for silos (2.9) for the...
I’m looking for flow properties of Portland cement. A chart or curve of how cement’s “unconfined yield strength varies with the “major consolidating pressure”. A chart or curve on how cement “density” varies with the “major consolidating pressure”. A chart or curve on how the “effective angle...
Recently purchased a 10 cubic yard horizontal ribbon mixer for concrete. What is a reasonable dynamic model for simulating the folding/mixing of the material in a drum? I'm trying to find out why the shaft seal is failing. From inspection it looks as if the shaft is undersized and deflecting...
