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:

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.
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.
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.

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.

Model ALLU DH3-17 TS 25 with double TS50 Axe blades

Kurdeez Minerals, based in Victoria, Australia, produces a range of natural products for soil improvement in agriculture, horticulture, and more. Their products are widely used in crop and biological farming to enhance soil quality and animal health. But they encountered a significant challenge in breaking down lime lumps to meet the 4mm size required for sale.

After a successful trial with Walkers Hammers using the ALLU DN 2-12 TS 25, Kurdeez Minerals invested in the ALLU DH3-17 TS 25 with double TS50 Axe blades. The ALLU unit not only broke down the lime lumps but also improved the flow of material into the ASTEC screener, significantly boosting productivity.

ALLU’s impact on Kurdeez Minerals can be seen in five key areas:

Increasing overall productivity.
Efficiently breaking down lime lumps.
Streamlining material flow into the screener.
Aerating the material during the process.
Delivering long-term reliability, even after five months of use.

Aidan, the quarry manager, was thrilled:

“This is the best attachment I have ever worked with after using it for 5 months.”

The addition of ALLU allowed Kurdeez to optimize their entire process, getting more done with fewer headaches and delivering higher-quality products to their customers.

The experience shows how the right equipment can turn challenges into opportunities, helping a business thrive with greater efficiency and ease. With ALLU, Kurdeez Minerals unlocked the full potential of their existing equipment, turning a slow, frustrating process into a highly productive and efficient workflow. This success highlights the power of smart investment in the right tools! We’re proud to have been part of Kurdeez Minerals’ journey and thank them for allowing us to share their success story.
