DESIGNING CONVEYOR
The DESIGNING CONVEYOR is done with the evaluation characteristics of the material and the angle surcharged.
- The system should have an idle time of zero creating a continuous flow of the system and materials.
- Invest in standard equipment which allows flexibility and needs low investment.
- The flow system should incorporate gravity to allow the flow of the system and the flow of the materials.
- The dead weight and payload ratio should be the minimum of the material handling equipment.
Belt width
The width largely relies on the belt speed and the quantity of the material conveyed. The system design and choice is done in relation to the volume loading on the system and the most economical system.
Pulley
The dimension and type of the conveyor belt determine the driven and driver pulley diameter. The essence of having the right diameter is to ensure that no undue stress is put on the belt in times of operation. The length from the center pulley accounts for the length of the belt, considering the distance parallel to the belt line. Capacity is measured by the belt cross sectional area and the speed of the belt. The roller facilities, free rotation of the belt in every direction. The roller diameters are chosen when one considered in relation with the belt width. There is a great relation between the roller diameter, the revolution power minute and the maximum belt speed.
Belt tensions and power
The longer the belt the more the power is needed and higher magnitude of power required. The longer the length of the belt the higher the vertical distance of the lift and the higher the power needed. To produce lift, power is required. The conveyor system the tension is much higher than being in a steady state.
Idler spacing
For conveyor systems transporting materials of 1500kg/m3 the idlers are put at a spacing of 1.0m. The idlers are installed to ensure they compensate for the tension of the belt compared to the load being transported. The minimum motor power is done by the power of the drive pulley and the efficiency of the reduction gear. The motor hose is the power required to move materials horizontally and elevate the material.
The system requires high capital base which limits the work design and performance evaluation. This limits the belt system however, each system is designed with automation in loading, unloading, movement. The best part is the system requires low initial capital, low maintenance and operational costs and it eliminates the repetitive short distance movement. The conveyor systems are safe and flexible for industries to use.

Shaft design is done by basically determining the shaft diameter that will transmit motion in different loading and operating conditions. The correct shaft strengthens the system and gives it the tight rigidity. The value of the pulley diameter and the belt width select the size of the shaft diameter from different hand books.
Programmable controllers
These are compact and also known as application controllers that are used to control the system. The controllers contain the supervisory functions such as speed control of the drivers, conveyor system, belt slip control, the speed difference between two motors and a driving drum and speed difference. Controllers are also known as application controllers.
Limitations and conclusion
The system requires high capital base which limits the work design and performance evaluation. This limits the belt system however, each system is designed with automation in loading, unloading, movement. The best part is the system requires low initial capital, low maintenance and operational costs and it eliminates the repetitive short distance movement. The conveyor systems are safe and flexible for industries to use.
