    BonnyView and  ALLU the perfect partners

    When mine and quarrying veteran Len Hardy decided he needed two “big” new buckets for his of Bonnyview Quarries business in NSW, he knew exactly what brand he wanted and where to turn to when he wanted to buy them.

    Having used a number of smaller ALLU buckets on his excavators over the years, Len had his eyes on a pair of ALLU DH4-23 XHD25 screening buckets to take on the bigger jobs and provide additional versatility to his operation, which supplies customers right across NSW.

    Built by Finnish private limited company ALLU Finland Oy, the ALLU screen crushers are highly versatile and the ideal tool for creating material such as road base and building materials.

    According to Len, they are the perfect fit for his business.

    “They are the best constructed buckets for the applications we use them for. They are really well engineered and provide a very reliable performance,” he said.

    “The two new buckets we acquired are performing really well and we couldn’t be happier.”

    Len is just as high in his praise for local ALLU support distributors in Australia, with whom he has had a lengthy relationship.

    “RDW group are a very, very, good company to deal with. They are great suppliers and will always come up with what you want,” he recently told Australian Mining Review.

    RDW group has been the Australian importer and distributor for ALLU for around four years. distributing the product through a nation wide network, servicing major infrastructure projects including water and gas , however, the versatile ALLU system is quickly making inroads with civil and composting contractors.

    Sales Area Manager in Rockbreakers Queensland, Craig Einam, said ALLU bucket applications and  installations continue to grow and develop each year.

    The versatility  of the buckets to be fitted to 5T – 80T excavators and larger style loaders makes them particular popular with quarry operators like Len, while the smaller buckets are also effective on skid steer loaders.

    Mining applications

    Efficient material flow is a key issue in any mining operation, power plant, bulk harbour and bulk material or storage area.

    ALLU Transformer Screener Buckets mounted on an excavator improve efficiency in material processing due to work speed and reach which results in almost double the processing capacity compared to a slow-moving wheel loader as a carrier.

    With ALLU’s Screener technology, existing loaders and excavators can be converted into effective processing, sorting and screening equipment due to the ALLU Transformers ability to deliver a one-step screening and loading solution capable of handling all materials from wet soils to coal and softer rock materials.

    This helps improve efficiencies through less chute blockages and also reduces the need for buffer storage areas and transportation of material heaps that are clogged due to moisture or contamination.

    When looking at a project with a holistic approach given multiple equipment mobilisations, fuel costs and cost to process in low margin return Ore reclaiming projects etc.

    ALLU Case studies have shown between $1.50-$2.50 per tonne savings in running costs in comparison to multiple unit processing configurations.

    The ALLU Transformer M series of buckets for mining applications suit 50 to 160 tonne excavators and 30-90 tonne wheel loaders. To meet the specific needs of each application – a range of blade and drum sizes are available to provide fragment sizes of 50, 75, 100 and 150mm.

    Oman

    Material Limestone

    Industry Crushing, Quarrying, Roadworks

    Application Limestone Crushing

    Function Break down large limestone boulders

    Model M 3-25 X75

    Crushing large volumes of limestone effectively calls for equipment that guarantees speed and accuracy. In the demanding environment of Oman, a customer chose the ALLU M 3-25 screening bucket, mounted on a Hitachi 90-tonne excavator, to handle limestone boulders with precision and speed. This solution not only eliminated the need for a conventional crusher but also transformed operations into a one-step process that saved time, reduced costs, and minimized environmental impact.

    The Challenge: Crushing Limestone Boulders for Road Construction

    The customer’s challenge was to break down large limestone boulders ranging from 0 to 300 mm into smaller, manageable pieces, specifically between 0 and 90 mm. The material needed to be prepared as sub-base for the internal road construction at the Royal Oman Police Headquarters. Conventionally, this would require multiple machines and permits to set up a traditional crusher on-site, causing additional costs and logistical complexities.

    The ALLU Solution: One-Step Operation with M 3-25 Screening Bucket

    Choosing the ALLU M 3-25 X75 over a traditional crusher setup, the customer valued its capacity to condense several stages of the process into one seamless operation. Mounted on a Hitachi 90-tonne excavator, the ALLU screening bucket ensured a smooth, efficient workflow throughout the operation. The excavator simply picked up the boulders, crushed them to the desired size, and loaded them directly onto trucks for transport.

    This one-step operation not only saved the customer significant time and reduced the need for additional equipment but also minimized environmental impact by reducing fuel consumption and the overall number of machines on-site. The crushed material was perfectly sized for the sub-base application, helping ensure that the project was completed efficiently and on time.

    Key Benefits of the ALLU Screening Bucket:

    1. Cost-Efficient Versatility: By choosing this screening bucket, the customer bypassed the permits and costs of a conventional crusher, while handling a large-scale operation with one versatile attachment.
    2. One-Step Process: The ALLU screening bucket streamlined the operation into a single process, from picking up material to crushing and loading it onto trucks.
    3. Sustainable Precision: Fewer machines on-site meant reduced emissions and fuel consumption, while the bucket’s precision ensured perfectly sized material for sub-base road construction.

    Why ALLU Stands Out for Material Processing

    ALLU’s innovative screening and crushing buckets, like the M 3-25, are engineered for large-scale operations in industries such as construction and mining. Designed for efficiency, they reduce the need for multiple machines while boosting productivity and streamlining job site processes. Whether you’re crushing limestone, screening soil, or preparing materials for road construction, ALLU delivers reliable, durable equipment that can handle even the toughest materials, transforming how you approach material handling.

    Model ALLU DH3-23 TS35

    Problem

    ALLU Bucket Delivers Efficient Quarry Waste Handling in China In the world of quarrying, managing waste efficiently is more than a necessity—it's a responsibility. Quarry owners often face the challenge of dealing with a mix of stone and clay, leftover materials that don’t seem valuable at first glance. But what if those materials could be turned into something profitable and even environmentally friendly? This is where the ALLU DH3-23 TS35 screening bucket makes a difference. Working alongside the CAT 336 excavator, this combination does more than just handle waste—it transforms it. Quarry owners found themselves searching for a solution that would allow them to handle waste effectively while still being cost-efficient. ALLU delivered just that.

    Solution

    From Waste to Resource in 3 Steps Handling leftover tailings and waste during quarry operations can be challenging. Often a mix of stone and clay, these byproducts are typically hard to sell or repurpose. But using the ALLU Transformer DH3-23 TS35, this waste gets a new life. The process follows three simple steps: 1. Raw Material Collection: Quarry waste, often seen as byproducts, is collected for screening. 2. Screening and Separation: ALLU's bucket separates larger stones (over 3 cm) from finer material (below 3 cm). The large stones are ready for direct sale to stone processing plants. 3. Resource Utilization: The finer material, perfect for road construction and landscaping, is repurposed, turning waste into valuable resources. The ALLU screening bucket separates materials by size, repurposing both large and fine particles. Larger stones are sent to processing plants for resale, while finer materials are used in road construction or landscaping. This process boosts the market value of the stone and provides additional economic benefits to quarry owners.

    Benefit

    Dual Benefits for Profit and Sustainability ALLU Transformer offers quarry owners an efficient, one-step screening service. By separating larger stones for resale and finer materials for road construction, this process maximizes resource use and brings financial returns. The recovered stones often hold more market value than raw materials, while the finer products serve environmental remediation purposes like land restoration. This solution reduces waste accumulation and promotes recycling, helping quarry owners balance profitability and environmental responsibility. It’s a win-win scenario: fewer waste piles, more revenue, and a positive environmental impact. Conclusion: Balancing Profit and Responsibility ALLU has proven that in today’s quarrying industry, efficiency, sustainability, and profitability don’t have to be at odds. By reducing waste accumulation and promoting resource reuse, ALLU helps quarries strike the perfect balance between economic growth and environmental responsibility. With the DH3-23 TS35 in hand, quarry owners can meet regulatory requirements, generate additional revenue streams, and contribute to a cleaner, greener future. It's not just about screening—it’s about turning challenges into opportunities. And that’s the power of ALLU.
