What is a Bulk Material Handling System?

Bulk Material Handling System for Aggregate

A bulk material handling system is designed to enable the movement, storage and control of bulk materials in various industrial settings. These systems employ a range of equipment that can help in reducing labour costs and enhance productivity. This article explores the basics and common challenges involved in bulk material handling.

What are Bulk Materials?

To best understand bulk material handling systems, it is important to know what is meant by a ‘bulk material’.

Bulk materials refer to substances that are handled, stored, transported and processed in large quantities and loose form. These materials can range from fine powders and granules to flakes, pellets or larger aggregates. In various industries, the efficient management of these materials is crucial as they often form the backbone of the production and supply process.

The physical behaviour of these materials is particularly important. Despite their solid nature, when in motion, bulk materials often exhibit fluid-like properties - like sand through an hourglass. This fluid behaviour is crucial for efficient transfer and processing, allowing them to flow through conveyors, chutes and hoppers smoothly.

Common Types of Bulk Materials

There is a wide array of bulk materials used across various industries:

Agricultural Products

Fertiliser, animal feed and additives and seeds, are some of the most common types of bulk material for the agricultural industry.

Construction Materials

Construction aggregates include sand, gravel, cement and more for use in the construction of buildings, homes, infrastructure and beyond.

Chemicals and Plastics

Lime, sulphur, soda ash and other chemical powders and granules, as well as plastic granules, are some examples of bulk materials within the chemicals and plastics industry.

Food and Beverage Products

Raw materials such as flour, sugar, grains and spices are handled in bulk within the food and beverage industry, where grains, powders and semi-solid substances are common.

Waste and Recyclables

This includes wood chips, plastic granules, Municipal Solid Waste (MSW) and paper pulp are all suitable for recycling, reducing demand for raw materials and volume of waste in landfill.

Power Generation

Materials such as coal, biomass (including wood pellets and agricultural waste) and coke used for energy production are frequently handled within this industry.

Pharmaceutical and Fine Chemicals

Powdered chemicals, Active Pharmaceutical Ingredients (API) and granulated raw materials make up some of the bulk material in the pharmaceutical and fine chemicals industry.

What is Bulk Material Handling?

Bulk material handling refers to the industrial processes that involve the storage, transportation and management of bulk materials. This field encompasses a wide array of specialised equipment designed to efficiently handle large quantities of materials, such as minerals, grains, metals and powders, ensuring they are moved safely and effectively throughout a facility.

To meet the diverse demands of various industries, from agriculture to mining and beyond, an extensive variety of bulk material handling systems have been ingeniously developed. Each system is tailored to facilitate the smooth flow of materials, minimise labour requirements and enhance operational efficiency across countless material handling applications.

Key Components of Bulk Material Handling Systems

Storage Systems

Storage systems include vessels, hoppers and silos. These systems are designed primarily for the storage of bulk materials, preserving materials under optimal conditions to maintain product quality and extend its shelf life.

Screw conveyor system

Conveying Equipment

Conveying equipment includes pneumatic transfer systems and mechanical screw conveyors.

These systems are designed for the transportation of bulk materials through facilitating the movement of substances across long distances of horizontal stretches and vertical inclinations.

Loading and Unloading Equipment

For loading and unloading operations, equipment such as bulk bags are used, ensuring materials are directed to the right system or location, ready for the next process.

Bulk bags and FIBC bulk bag stations can be integrated into various conveyors and feeders for easy loading and unloading.

Common Challenges in Bulk Material Handling

There are many elements besides equipment to consider when creating an effective bulk material handling system. Below are some of the common considerations that must be taken into account:

Material Characteristics and Flow

Consider whether the bulk material is free-flowing or poor-flowing, as this will affect the design of the system.

Flow properties can be affected by bulk density, temperature, particle size, material form and more.

Materials handling systems can be designed to handle specific materials and material flows, setting and maintaining the correct flow rate for precision in your operations.

Dust Control

For many industries, controlling the amount of dust in the atmosphere is a priority. Dust-free discharge systems and transportation equipment designed to minimise dust will be essential for operations where controlling dust is a health and safety concern.

Safety Concerns

Industries such as food and beverage and pharmaceuticals will have high safety standards they need to meet, making materials handling equipment designed to minimise contamination and cross-contamination a priority.

Handling equipment made from easy-to-clean surfaces and designed with controlled conditions in mind can support these requirements.

Equipment Wear-and-Tear

When investing in bulk material handling equipment, you want to be sure your equipment is designed for longevity. Equipment wear-and-tear and corrosion is a consideration for many, especially for those in industries where corrosive and abrasive bulk material is common.

High-quality designs and materials, plus easy access for maintenance and upkeep, will ensure handling equipment is designed for longevity.

Industries Relying on Bulk Material Handling

Agriculture

Agricultural practices are heavily centred around the storage, mixing, processing and distribution of bulk materials, across both arable and pastoral farming operations.

In the agricultural industry, reducing dust and contamination, while maintaining the quality of the end product, are some of the qualities sought for in materials handling equipment.

Food Processing

For the transportation and processing of food and beverages and by-products, bulk material handling systems support all stages of food processing operations.

Maintaining strict hygiene standards and eliminating cross-contamination are some of the leading priorities for these systems within the food processing industry.

Chemical Manufacturing

It’s critical that for the safe and efficient transportation and storage of chemical substances, bulk material handling systems are developed to reduce human exposure to hazardous substances and minimise risk of contamination.

To maintain the quality of the product and to ensure longevity of machinery, bulk material handling systems should maintain accuracy and efficiency even when handling potentially corrosive materials.

Pharmaceuticals

In order to avoid contamination, inconsistent dosing, dust generation and a loss in product quality, materials handling equipment plays a critical part in the production of pharmaceutical drugs.

The tight regulation surrounding the pharmaceutical industry means that materials handling equipment is often high-spec and designed for precision performance.
