Off-The-Road (OTR) tyres are critical for material transport by loaders and haul trucks in mining and quarrying sites. Mining and quarrying companies face many challenges in maintaining the longevity of the tyres because of operation in highly abrasive environments, which leads to a relatively short lifespan.

Tyres are exposed to sharp-edged rocks or metal debris. Even water is detrimental to a tyre because a dry tyre, when subject to water, is more susceptible to punctures (See the comparison pictures of a dry tyre that is hard versus a wet tyre that can be cut by a knife). All these contribute to unplanned downtime and loss of productivity. In addition, the disposal of end-of-life tyres is an environmental challenge, with Australia discarding over 130,000 tonnes annually.

Operational Impact of OTR Tyres

OTR E2 tyres possess a Shore A Hardness of approximately 60. They are designed to optimise flexibility, load distribution, and cushioning for heavy-duty applications. However, this softness renders them vulnerable to damage in the harsh conditions prevalent in Australian mines, from the Pilbara's open-cut iron ore mines to Queensland's underground coal seams. Tyre wear is influenced by operator skill, weather conditions, equipment maintenance, and haul road conditions.

The huge size of mining machinery, such as haul trucks capable of transporting hundreds of tonnes or front-end loaders with large buckets, also imposes stress on the tyres. A single OTR tyre can exceed four meters in height and can weigh several tonnes. Whether bias or radial construction, exposure to jagged rocks and abrasive surfaces can lead to rapid degradation.

A single OTR tyre costs tens to hundreds of thousands of dollars. When a tyre is punctured or damaged, in addition to the immediate financial loss, unplanned downtime for repair or replacement impacts profitability. Common damage types include tread cuts, sidewall damage, chunking and bead failures, frequently aggravated by poor haul road conditions, overloading and incorrect inflation.

The Role of Tyre Protection Chains

Tyre Protection Chains (TPCs) are an ideal solution to protect tyres against damage and punctures. RUD manufactures TPCs from high-alloy, hardened steel, forming a close-mesh protective barrier that covers the tread and sidewalls. This robust mesh absorbs impacts from sharp objects and prevents catastrophic failure or premature wear.

RUD supplies 65% of the world's TPCs. By adopting new technology from long-established welding, forging and heat-treating methods, RUD has developed superior tyre protection and traction chains. The high-quality steel undergoes heat treatments and forging processes, enhancing wear resistance and durability. RUD TPC links ensure optimal grip and traction, even in challenging, wet, and slippery conditions. The additional chain weight is outweighed by the benefits of extended tyre life and improved machine uptime.

Benefits of Tyre Protection Chains

Implementing TPCs delivers measurable benefits for any mining or quarrying operation, positively impacting safety and reducing financial costs.

Enhanced Safety: RUD TPCs improve safety by providing superior traction and preventing machines from losing traction on loose or steep surfaces. They are a safety measure against sudden tyre failures (blowouts and rapid deflations), which can be catastrophic. Reduced tyre-related breakdowns also minimise personnel exposure during emergency repairs, aligning with Australian safety regulations on the site, particularly those identified in Recognised Standard 13

Reduced Operating Costs: Tyres represent a large operating expense. TPCs extend tyre life, translating into fewer tyre purchases, reduced disposal costs and decreased labour for maintenance and replacement. By safeguarding against damage, TPCs enable mines and quarries to achieve the full lifespan of OTR tyres

Increased Productivity and Machine Availability: TPCs impact productivity by reducing unplanned downtime. Tyre-related downtime for haul trucks or loaders can disrupt production. By ensuring machine availability and optimal performance, TPCs can minimise costly interruptions.

The Last Word

OTR tyres are fundamental to mines and quarries, but their potential for damage requires protection. TPCs are critical to safeguarding the tyres, enhancing safety and maintaining production. They are an investment that can reap benefits due to reduced costs, increased uptime, and a safer working environment.

The Australian cement manufacturing industry relies heavily on efficient material handling for its complex processes, from raw material extraction to the final product. This article explores the crucial role of material conveying equipment in enhancing productivity, safety, and sustainability within Australian cement plants and highlights RUD Australia's tailored solutions.

Cement extraction is a complex process that requires efficient management of various raw materials. Given the logistics of manufacturing and the sheer volume and weight involved, material handling equipment is an essential component in any cement plant.

Since material handling equipment is used throughout the cement process, from extracting limestone to moving bulk clinker, proper use can enhance productivity and simplify operations.

As an innovative technological trendsetter, RUD provides a range of material handling solutions and equipment that can withstand the challenging conditions of the cement industry.

Significance of Material Handling Equipment in Cement Production:

Material conveying requires the safe and efficient transportation of raw materials (mainly limestone, gypsum, and fly ash) and bulk products (clinker). The right equipment can ensure safety, decrease downtime and ensure compliance with environmental and industrial standards.

Types of Material Handling Equipment for Cement Production

Bucket Elevators

Bucket Elevators transport bulk materials vertically, such as powdered lime scale or clinker. They also transfer, lift, convey, and store materials between different levels using less space and a large volume. Based on the application, a suitable (Chain or Belt) bucket elevator can be selected.

Benefits of Bucket Elevators:

• They can move bulk material vertically
• They keep the materials moving between the phases of production
• They are suitable for both powdery and fine granular material

Drag Chain Conveyors

Drag Chain Conveyors can transport a wide range of bulk materials. Their operation is based on the continuous movement of a chain placed in a rectangular section steel trough with a dust cover, coupled to a drive gear and sprockets/wheels. Although the material is usually dragged along the bottom of the trough by the lower section of the chain, it is also possible to convey material in the upper part. The drag chain conveyors from RUD are high quality, with sturdy construction, simple to set up for easy maintenance and reliable.

Benefits of Drag Chain Conveyors:

• Built to withstand heavy loads and rigorous operating conditions
• Can be tailored to specific application requirements, ensuring optimal performance
