2. Introduction to Conveyors
A conveyor system is a mechanical setup used for
material transport within facilities or between locations,
employing belts, rollers, or chains. It automates material
handling processes in industries, enhancing efficiency
and safety. These systems consist of conveyor
surfaces, drive units, and support structures, improving
productivity and material transport capabilities.
3. Factors to consider
• Material type and characteristics: Consider the size,
shape, weight, and other properties of the materials to
choose a conveyor that can handle them efficiently.
• Throughput requirements: Evaluate the speed and volume
of materials to ensure the conveyor meets the production
demands.
• Environmental conditions: Take into account factors like
temperature, moisture, dust, and corrosive elements that
may impact conveyor performance.
• Space limitations: Assess the available space for
installation, including height, width, and layout constraints.
6. Typical Belt Conveyor Components
A typical belt conveyor consists of the following components:
1. Motor
2. Conveyor Belt
3. Idler Rollers
4. Drive Unit
The motor provides the power to drive the conveyor belt. The conveyor belt is responsible for carrying the
material from one point to another. The idler rollers support and guide the belt along the conveyor's path. The
drive unit controls the movement of the conveyor belt. The tensioning device keeps the belt tight for efficient
operation. The support frame provides a sturdy structure to hold all the components of the conveyor system
together.
7. Applications of Conveyors
Conveyors are used across various industries for different applications, including assembly lines, packaging,
food processing, and baggage handling in airports.
Manufacturing
Conveyors streamline production processes,
moving products between different stages of
manufacturing efficiently.
Logistics
In warehouses and distribution centers, conveyors
facilitate the movement of goods for storage and
shipping.
8. Hazards Associated with Belt Conveyors
While conveyors offer significant benefits, it's crucial to be aware of potential hazards. These include pinch
points, entanglement hazards, and falling objects. Implementing safety measures is essential to mitigate these
risks.
1 Pinch Points
Areas in the conveyor system where it's possible for a body part or clothing to get caught.
2 Entanglement Hazards
Risk of hair, clothing, or jewelry becoming entangled in the moving parts of the conveyor.
3 Falling Objects
Items falling from the conveyor can cause injury to workers or equipment damage.
9. Safety Measures for Belt Conveyor
Systems
Preventing accidents involving conveyors requires implementing safety protocols. This includes
proper training, clear labeling of hazards, and regular equipment inspections.
Training
Employees should be trained to operate
conveyors safely and understand
emergency procedures.
Hazard Signage
Clearly marking hazards and providing
safety instructions can prevent accidents
Equipment Checks
Regular inspections and maintenance protocols are essential for ensuring the safe
operation of conveyors.
12. Roller Conveyors: Applications,
Hazards, and Safety Measures
• Applications: Roller conveyors are used in assembly lines,
warehouses, and material handling to move items efficiently.
• Hazards: Common hazards include pinch points, entanglement, and
material falling from the conveyor.
• Safety Measures: Safety measures involve proper guarding,
employee training, and regular maintenance to prevent accidents.
15. Chain Conveyors: Applications,
Hazards, and Safety Measures
1 Warehousing & Distribution
Chain conveyors are commonly used for transporting goods in warehouses
and distribution centers due to their high load capacity and durability.
2 Manufacturing
In manufacturing facilities, chain conveyors are utilized for moving heavy
materials such as automotive parts and large components along the
production line.
3 Hazards and Safety Measures
It's essential to regularly inspect and maintain chain conveyors to prevent
chain breakage and ensure worker safety. Safety measures include proper
guarding, employee training, and emergency stop controls.

17. Bucket Elevators: Applications,
Hazards, and Safety Measures
Grain Handling
Bucket elevators are commonly used for vertically transporting grain and other bulk
materials in agricultural and industrial settings.
Spillage Hazards
Hazards may arise from material spillage due to overfilling, leading to slip and fall
accidents and equipment damage.
Protective Guards
Safety measures include the use of protective guards to prevent access to moving
parts, reducing the risk of entrapment.
Fire Prevention
Applications in the agricultural industry require additional safety measures to prevent
dust explosions and fires.
18. Safety Measures for Conveyor Systems
Regular Inspections
Conduct daily, weekly, and monthly inspections
to ensure the system's integrity.
Training Programs
Provide comprehensive training to all personnel
on safe operation and emergency procedures.
Emergency Stop Buttons
Install and clearly label emergency stop buttons
at strategic points along the conveyor system.
Proper Guarding
Implement physical guarding and barriers to
prevent access to moving parts and pinch
points.
19. Introduction to Pneumatic
Conveyors
Pneumatic conveyors are systems used to transfer bulk materials using air
as the conveying medium. They are commonly employed in various
industries due to their efficiency and ease of use.
20. Applications of Pneumatic Conveyors
Food Industry
Pneumatic conveyors are
widely used in food processing
for transferring grains,
powders, and other food
products.
Pharmaceutical Industry
They are essential for the safe
and hygienic transfer of
pharmaceutical powders and
granules.
Chemical Industry
Pneumatic conveyors facilitate
the movement of chemicals
and granular materials without
contamination.
22. Hazards Associated with
Pneumatic Conveyors
1 Abrasive Materials
The movement of abrasive materials can lead to equipment wear and
tear, potentially causing breakdowns.
2 Airborne Dust
Exposure to airborne dust from the materials being conveyed can
pose respiratory health risks.
3 Explosion Risks
In certain environments, the presence of flammable materials can
lead to explosion hazards.
23. Safety Measures to Prevent Accidents
and Injuries
Regular Inspections
Implement routine inspections to detect
and address any potential issues before
they escalate.
Proper Training
Ensure all personnel involved are trained
in safe operation and emergency
protocols.
Equipment Maintenance
Regular maintenance of the conveyors and related machinery is crucial for safe operation.
24. Importance of Regular Maintenance
and Inspections
Enhanced Equipment Lifespan
Regular maintenance prolongs the lifespan of pneumatic conveyors, reducing the
need for frequent replacements.
Optimized Performance
Well-maintained systems operate more efficiently, contributing to overall
productivity and cost savings.
Safety Assurance
Maintenance and inspections ensure that the conveyors are safe for operation,
preventing accidents.
25. Training and Education for Safe
Operation of Pneumatic Conveyors
1 Hands-On Training
Providing practical training sessions for personnel to familiarize themselves with
equipment handling.
2 Emergency Response
Employees should be educated on emergency procedures in case of conveyor-
related incidents.
3 Continuous Learning
Encourage ongoing education to stay updated on safety practices and system
advancements.
26. OSHA Guidelines for Conveyor Safety: 29 CFR 1926.555
Regular Inspections Ensure conveyor systems are regularly
inspected for potential hazards.
Emergency Stop Devices Install emergency stop devices to quickly halt
conveyor operations when necessary.
Training Programs Implement comprehensive training programs for
all personnel working with conveyors.
Guarding Properly guard all moving parts and pinch points
