Q:

Which of the following is false about conveyors?

A) Cleats can be used to prevent slipping B) Backstopping brakes are used for straight belts
C) Anti-static belts are used when electric components are conveyed D) Soft starters avoid overloading the motor
 
Answer & Explanation Answer: B) Backstopping brakes are used for straight belts

Explanation: Heavily loaded conveyors that are inclined, are prone to getting slipped backward and therefore, the backstopping brakes engage automatically with the de-energization of motors. Cleats are used to create separation between the products being conveyed and prevent slipping as well.

Q:

Which of the following is false about conveying systems?

A) An essential factor to consider before choosing the right conveyor system is the environment of operation B) Conveyors cannot be used as feeders
C) The composition of the material being conveyed is very important D) The surrounding temperature is one of the deciding factors
 
Answer & Explanation Answer: B) Conveyors cannot be used as feeders

Explanation: A conveyor can be used as a feeder also. The feeding action is more time sensitive and precise than the conveying action. The tumbling effect of a conveyor also becomes very crucial during the feeding action.

Q:

Choose the correct unit of throughput.

A) Cubic feet per minute B) Meter cube
C) Square feet per second D) Meter square
 
Answer & Explanation Answer: A) Cubic feet per minute

Explanation: Throughput is a measure of the capacity of the conveyor to handle bulky materials. Throughput is always measured as the rate of volume flow, which implies that the units are of the form, volume per time. Therefore, from the given set of options, cubic feet per minute is the right option as it has the units of volume per time.

Q:

Which of the following is true about frame configuration?

A) Frame configuration refers to the size of the conveyor B) Frame configuration refers to the size and shape of the conveyor
C) Frame configuration refers to the capacity of the conveyor D) Frame configuration refers to the shape of the conveyor
 
Answer & Explanation Answer: D) Frame configuration refers to the shape of the conveyor

Explanation: Frame configuration is an important, conveyor system specification. It refers to the shape of the frame of the conveyor, which could be straight, curved or z shaped. Capacity of the conveyor and size of the conveyor are characteristics that affect the ‘Throughput’.

Q:

Which of the following is a correct description about the different types of conveyors?

A) Belt conveyor transports material in any direction B) Slat conveyor requires high maintenance
C) Vibrating conveyor can convey materials of any friction factor D) Screw conveyors usually handle lightweight materials
 
Answer & Explanation Answer: A) Belt conveyor transports material in any direction

Explanation: One of the major advantages of a belt conveyor is that, it can carry bulk materials in any direction. Slat conveyors are highly reliable and require low maintenance. In a vibrating conveyor, the material being carried should have a high friction factor with respect to steel so that, the conveying action can be transmitted throughout the material. Screw conveyor usually carries bulky materials.

Q:

What do you mean by ‘Conveyor control’?

A) Controlling the material flow, according to conveyor speed, to reduce power consumption B) Controlling the conveyor speed, according to material flow, manually
C) Controlling the material flow, according to conveyor speed manually or using feedback drives D) Controlling the conveyor speed, according to material flow to, reduce power consumption
 
Answer & Explanation Answer: D) Controlling the conveyor speed, according to material flow to, reduce power consumption

Explanation: Conveyors can be run continuously or with varying speeds. Controlling the speed of the conveyors, according to the rate of material flow, is called conveyor control. It is done in order to reduce the power requirements and thereby, have a cost effective production. Variable speed drives are used when speed of the conveyor needs to be changed based on certain factors. Its speed can be changed manually or via feedback drives.

Q:

Which of the following does an auxiliary equipment not do?

A) Act as a major equipment without which production is not possible B) An auxiliary equipment makes production easier
C) An auxiliary equipment enhances production in some cases D) An auxiliary equipment makes production dynamic
 
Answer & Explanation Answer: A) Act as a major equipment without which production is not possible

Explanation: Auxiliary equipment is an add-on equipment that makes production easier however, is not the main equipment used for production. They can enhance production and help in producing a variety of products for example, using Filling & Weighing station in a chocolate industry can help produce chocolate in different types of boxes.

Q:

Which of the following is true about the speed of the conveyor belt?

A) Fixed conveyors need not be shut down during any speed change B) Adjustable speed belts can be changed only manually
C) Fixed speed drives can undergo minor speed changes D) Variations of speed is not possible with conveyors
 
Answer & Explanation Answer: C) Fixed speed drives can undergo minor speed changes

Explanation: Conveyor belts can either have a fixed speed or an adjustable speed. A fixed conveyor always needs to be stopped before changing the speed. With an adjustable conveyor a variation of speed is possible, both manually and automatically, by changing speed while the conveyor is in operation.
