Why 'banbury mixer' is used for tire compounding instead of 'Inter mix'?

Both banbury mixer and internal mixer could be used for tire compounding. Nowadays, some tire manufacturers use the banbury mixer instead of the internal mixer, because they want to get higher output/capacity. Usually, minimum volume for the banbury mixer is 75 L, capacity is around 1500 kg/h. If there is any questions, send email to cnsabrina@aol.com

How does a knife edge bearing work?

A knife edge bearing is used to provide a low friction pivot point for a slow moving, low loaded rocking arm; for example a balance beam as in the old-fashioned shop weighing scales. The rocking arm is supported at its pivot point by a cross bar. The two ends of the cross bar are machined such that a line across their bottom edge becomes a knife edge, with the two faces of the knife blade forming an angle of about 60 deg. This knife edge pivots on two supporting pillars, one each side of the arm, which carry the weight of the arm and any applied loading. Very simple and reliable, the only problem being with wear of the knife blade over time, especially with heavier loads or fast repeated movement.

What is the heat number in material identifications?

The heat number is an identifying number assigned to the product of one melting in an electric arc furnace. Usually, but not universally: * the first digit indicates the furnace number * the second digit indicates the year in which the heat was melted * the last three (and sometimes four) indicates the melt number. So for example, a heat number 199202 indicates that the product is from the 202nd heat melted in furnance 1 in 1999.

normally self tapping screws do not have a fianl run down angle specified. It only has has got the Run down torque.This is because the forming torque and the final torque are too close.This is also the reason that some times u reach the angle that you set to run down but still the bolt has not bottomed down.

How can you make a tank with capacity of 1000 liters let me know its height width and length and please tell me about both square and tube?

1000 liters means one million cubic centimeters (106 cc) so if you had a perfect cube with all sides 100 cm (ie 1 meter) it would be 1000 liters or 1 cubic meter. This is obvious because 1 cubic meter of water weighs one tonne or 1000 kg.

If you had a drum shaped tank with a base of diameter 1 meter, the base area would be 0.7855 sq meters, so to get a volume of 1 cubic meter it would have to be 1.273 meters high. please show me an example

Why the output of the operational amplifier positive even if the inverting input voltage is more also?

If the output of the operational amplifier is inconsistent with the inputs, then you are operating outside of the limits of the device. You might also have experienced lockup, a characteristic where the output locks in one state, but this still stems from operating outside of limits. Make sure the inputs are always within the specified range.
