Conveyor Problem

But there are some problem with the conveyor that we need to improve. First is transition distance. We need to determined the correct transition distance to avoid the belt damage. Second is, vertical curve. Vertical curves come in two different styles, concave and convex. Both types of curves create belt operational problems when the curve is designed with a shorter radius than required.

So we need to design it very properly to allow the belt to lay in the idlers when the belt is running empty or full without lifting off of the idlers. The third one is, pulley crown. Crowned pulleys for lightweight conveyor belts can be trapezoidal or radial shaped. We need to make sure that the pulley is effective. And the last one is loading station. Two of the more common reasons of belt failure are a direct result of the loading stations. These are holes being punched in the belt due to impact and carry cover deterioration due to abrasion. Therefore we must do an analysis on how to reducing product freefall and impact
to the belt.

Conveyor Current Issue

As i stated above, newer current conveyors use high-frequency devices like operational amplifiers no longer have to be limited by conventional gain bandwidths. Current conveyors are used in high-frequency applications in which conventional operational amplifiers cannot be used. Those operational amplifiers are limited by their gain-bandwidth product.

In theory, the current conveyor is only limited by the ft of the transistors that are being used in its design. Among the contemporary applications in which the current conveyors are used are RF mixers, high-frequency precision rectifiers, and medical applications like electrical impedance tomography (EIT). So the conveyor is very important in industry, and almost all the industry use conveyor in making their product.
