- Which of the factors listed below is not considered when selecting the types of conveyor chains and components to be used on conveyor system.
A) The types of product to be handled
B) Any specification of conveyor chains and components available for supply.
C) Operating condition of the line
D) The specification of the conveyor chains and components
The types of product to be handled: Yes, one of the factors to be considered when selecting a conveyor is the type of the product to be run. On RGB( returnable glass bottles) line they make use of steel conveyor while the bead conveyor is used for can lines because of the type of product. Glass bottle are will spoil the bead conveyor and the stainless conveyor will cause scratch or dent on can if used.
Operating condition of the line: the operating condition of conveyor on RGB lines should be 45⁰ centigrade or below it varies for Pet( polyethylene teraphthalate) lines
Any specification of conveyor chains and components available for supply: These factor is not considered when choosing a conveyor. For instance, coca-cola bottling company will not want to know if a manufacturer have their required or specified conveyor or not, if they don’t have what they’re looking for they will request it from a manufacturer that have what they’re looking for e.g krones or sidel
So therefore, the correct answer is B ( any specification of conveyor chains and components available for supply)

- Listed below are benefits derived from proper and thorough cleaning of conveyor systems except
A) Increased line availability
B) Optimized line efficiency
C) Increased number of line stoppages
D) Apreciable reduction in maintenance cost
Increased line availability: No matter how old a line is it will continue to produce optimally as soon as the trained personnel is properly maintaining that machine adequately.
Optimized line efficiency: The efficiency of a line could be increased due to meticulous care of the conveyor system.
Increased number of line stoppages: This is not part of the benefits of properly and thoroughly cleaning the conveyor system
Appreciable reduction in maintenance cost: If a line is properly maintained the company has no reason to repair or replace the conveyor hereby reducing the cost of maintenance. Some of our lines conveyor or parts cost more than millions so a preventive maintenance will result to little or no cost of maintenance.
The correct answer is C(increased number of line stoppages)
- Listed below are reasons why thorough cleaning of conveyor systems is necessary except
A) To keep bacteria situation of the conveyor under control
B) To optimize the service life of conveyor chains and components
C) To increase the speed of the conveyors on the conveyor system
D) To keep the friction level of the line low
To keep bacteria situation of the conveyor under control: Meticulous care of the conveyor will prevent bacteria or contamination from entering the product.
To optimize the service life of conveyor chains and components: How old a line or machine is doesn’t matter how optimally it will function as soon as the trained personnelis giving the machine proper maintenance
To increase the speed of the conveyors on the conveyor system: Thorough clean of conveyor can’t increase the speed of the conveyor. The speed of the conveyor is determined by the speed of the machine operated at that particular time.
To keep the friction level of the line low: There will be no resistance or restriction on the part of the conveyor system in order to run the line efficiently.
The correct answer is C ( to increase the speed of the conveyors on the conveyor system)
