Factors to consider while designing Bulk Material Handling Design & System
Designing a bulk material handling system is no laughing matter – but that doesn’t mean it has to be a dry and boring process! In this blog post, we’ll look at the various factors you need to consider when designing your bulk material handling system, as well as some of the unique challenges you may face along the way! Let’s get started on your journey towards an efficient bulk material handling setup.
Introduction to Bulk Material Handling Systems
Bulk material handling design & system are used in many industries to efficiently store and transport heavy, loose, and bulky materials. These systems provide a safe, reliable, and cost-effective way to move large quantities of materials in a short period of time. Bulk material handling systems can be used for mining, construction, packaging, food processing, manufacturing, and other industries.
The design of bulk material handling systems has to consider the unique requirements of each application. The system must be able to move the right type and quantity of bulk material without damage or injury. Factors such as size, weight capacity, handling time requirements, safety features, cost-effectiveness and reliability must all be taken into account when designing the system. In addition to these factors there are also other important considerations such as environmental regulations that will further dictate the design choices that need to be made when creating a new system or upgrading an existing one
Types of Bulk Material Handling Systems
Depending on different industries, the type of Bulk Material Handling System varies. There are several types of Bulk Material Handling Systems that are distinguished according to their configuration, product characteristics and system capabilities. Below are the most common types of Bulk Material Handling Systems:
1. Conveyor Belt System: This is the most widely used system to move bulk materials horizontally or on an incline at a controlled rate. A combination of two or more conveyors can be used to transfer bulk materials through a plant efficiently and over long distances as well. A conveyor system can be combined with other material handling equipment for efficient process flow.
2. Truck Unloading/Loading System: Truck unloading and loading systems refer mainly to a collection of equipment that is used to unload materials from trucks and load them on different conveyors or other material handling equipment along the production line. Equipment such as hoppers, dumpers, conveyors etc., are typically used in truck unloading systems. Such systems can be customized according to product characteristics and production requirements.
3. Blending/Mixing System: Mixing systems are usually combined conveying and feeding operations in order to mix bulk solids accurately, homogenously and uniformly with no segregation during processing or transfer operations in industries such as food processing, pharmaceuticals or chemicals etc., Blending systems use machinery like pneumatic blenders, tumblers etc.,
4. Automated Storage & Retrieval Systems (AS/RS): AS/RS refers mainly to a computer-controlled operation containing automated storage-retrieval machines which operate within an enclosed structure like a warehouse where goods are automatically stored and retrieved without any operator intervention via computer interfaces for more efficient storage utilization compared to manual operations for large storage volumes
5 . Automated Palletizing System: An automated palletizing system is basically an end-of-line type robot system involving multiple robots managing multiple pallets simultaneously at high speeds without operator intervention in continuous production lines for better efficiency compared manual processes as it results in time savings with virtually no errors made compared manual operations
Factors to Consider During Design
There are several factors that must be considered in order to design an effective bulk material handling system. These include the type of material, flows, capacities, distances, environmental considerations, operator safety and ergonomics. It is important for designers to take into account all these characteristics when creating the system.
The type and size of material being handled play an important role in the design of a bulk material handling design and system as these impact flows, capacities and other factors that must be taken into consideration. The desired flow rate or capacity will determine much of the rest of the design features including required conveyor speeds and power ratings, as well as drive configurations.
Another factor to consider during design is the environment in which the system needs to run. Where will it be located? Which weather conditions will it need to operate effectively under? Will there be any extremes in temperatures or moisture levels? All these questions should be considered in order to ensure successful operation over time.
Operator safety and ergonomics are key elements that must also be addressed during a bulk material handling system’s design phase. Considerations such as guard railing height, emergency shut off systems, railings on access points and ladders should all be taken into account to ensure maximum operator safety at all times. Additionally, certain aspects like belt tracking can help improve operator comfort for longer periods of operation at any one time.
a. Cost
When considering the cost of a bulk material handling system, one should take into account the initial capital investment and installation costs as well as ongoing maintenance and replacement costs. It is important to factor in all relevant expenses when designing a system to ensure that it can be operated within budget. Depending on the material being handled, some parts of the bulk handling system may require more frequent replacement, thus driving up operating costs. Additionally, any automation elements should be carefully weighed as they often require larger up-front investments but can pay off in increased efficiency and productivity over time. It is essential to consider not just the upfront cost, but also what will be required for proper operation in order to make an informed decision about the best approach.
b. Capacity
Capacity is one of the most important factors to consider when designing a material handling system. It creates the basis for dimensioning and ensures that a sufficient flow-rate is available to satisfy operational needs. It also has an impact on the size and complexity of components in a material handling system, and ultimately affects the cost of purchase, operation and maintenance.
The capacity should be determined after assessing various parameters such as the materials’ physical properties, total quantity and necessary frequency of supply movement into storage or onto production areas. The appropriate dimensions must also be defined in order to ensure that maximum efficiency is achieved by all elements within the material handling system, especially if variable load factors are possible.
It’s important to have adequate reserve capacity as additional requirements may arise over time due to extended production runs or changes in throughput. Reserve capacity should also be factored into plans in order to cope with malfunctions or plant maintenance tasks which could lead to temporary overloading situations. Every planned alteration should always consider potential usage peaks lasting several hours or days before modifications are made.
c. Safety
The safety of personnel and equipment is paramount in designing a Bulk Material Handling System. Conveyors move large quantities of raw materials, high volumes of feedstock, aggressive chemicals and sometimes even people in manufacturing and industrial sites. Operating safely means protecting the organization from potential liability due to injury, property damage or pollution due to an incident with its equipment.
There are regulatory standards that govern the design and operation of bulk material handling systems in most countries. These are limits intended to avoid accidents, such as belt speed limits or maximum length travelled by a trolley on an overhead track before it stops at a station, with prescribed safety mechanisms applied when these parameters are exceeded. Hazardous locations may require specific design elements such as explosion-proof motors. Similarly, formal worker safety risk assessments must be carried out prior to any installation or operational start-up to ensure that all personnel have been adequately trained in equipment safety procedures.
Beyond regulations, proactive measures should also be undertaken by the organization such as machine guarding for rotating shafts and pulleys or proper distances for pedestrian walkways around moving conveyors etc., along with Warning signs at points of danger e.g blocking hazards like pinch points or hazardous substances being used for lubrication. This list can extend further depending upon the particular application but these are typical steps included in most material handling system designs..
d. Environmental Impact
The environmental impact of bulk materials handling systems must be taken into consideration to ensure a sustainable, safe and efficient system. Before designing a system, it is important to understand the potential risks posed by bulk material handling processes. Potential sources of pollution include air emissions, fugitive dust, water discharge, runoff and noise. Every effort should be taken to mitigate the environmental impacts associated with bulk material handling processes.
Air emissions in particular can potentially cause serious health issues for people working in or living near the area where bulk materials are handled. Proper planning will minimize significant environmental impacts from operations such as fugitive dust which can result from plant site and equipment operation when not properly managed and contained. Noise pollution while operating plant equipment also needs to be addressed as an issue posed by Bulk Material Handling Systems as it could have adverse effects on workers’ health and well-being as well as any nearby residential areas and wildlife.
Water discharge resulting from various operations such as handling waste materials requires careful management during design procedures that consider best management practices for preventing pollutants from entering bodies of water or groundwater sources. Moreover, runoff must also be addressed since uncontrolled runoff can pollute natural water sources, leading to habitat destruction and ecosystem degradation.
e. Maintenance Requirements
When designing a Bulk Material Handling System, it is important to consider the amount of maintenance required. Maintenance requirements can vary greatly depending on the materials being handled and the environment they are used in. It is essential to install an appropriate maintenance plan from the start, so that systems remain reliable and efficient.
Maintenance activities should include regular inspections, preventive measures such as lubrication/ greasing or other consumables, and adjustments as necessary. Careful records should be kept to monitor performance and track previously completed maintenance tasks. Further considerations for maintenance include:
– Selecting appropriate material of construction for components that are subject to wear
– Scheduling preventive maintenance with sufficient time between operations
– Training personnel on using safe work practices when conducting inspections
– Selecting various tools for inspecting components such as tightness testers, torque wrenches and more
– Utilizing safety guards if needed
