CDE, a leader in the design and engineering of sand and aggregate wet processing solutions, has revealed a new ProPress high-performance filter press at Hillhead 2024

At the show, which ran from 25-27 June in the United Kingdom, the leader in waste recycling and natural minerals processing sectors, displayed the latest addition to its lineup of water management and recycling systems. According to the company, the ProPress features patent-pending technology, benefits from a flexible design and variable throughput that can be scaled to fit the processing volume of any operation. It has been delivered to meet the evolving needs of the construction and demolition (C&D) waste recycling, quarrying, and mining sectors.

A break from the norm

Unlike traditional filter presses, the system is dual feed, meaning sludge is fed from both sides of the ProPress for improved efficiency and faster cycle times. Optimised sludge feed pressure also allows for faster dewatering to increase overall throughput. This is further supported by an overhead beam design that ensures reliability by reducing stress on the unit and improving its durability.

The ProPress features plates that are 25% larger (2.5 m x 2 m). Greater chamber volume and overall fewer plates serve to provide maximum capacity on a smaller footprint and improve mechanical cycle times.

Safe and efficient maintenance is made possible by integrated plate-shaking technology which addresses filter cake build-up within chambers to help reduce the need for manual intervention. An access walkway provides clear and unobstructed means to carry out maintenance safely and efficiently, and flush mounted drip trays reduce material entrapment and lock in place to provide a secure maintenance platform for operators.

The smart design is supported by an innovative, multifunctional robot, which serves as the main workhorse for the ProPress, controlling plate opening, plate shaking, cloth washing, plate winch, and the maintenance platform.

The CDE ProPress is available in a range of different sizes to suit all markets and applications. Available globally, the ProPress is also largely pre-assembled to expedite commissioning, allowing operators to get up and running quickly to help achieve fast return on investment.

With the CDE ProPress, owners and operators can recycle up to 95% of process water for immediate reuse in their wash plant while simultaneously cutting waste disposal fees by recovering a filter cake product that can be used for pipe bedding and landfill capping. This eliminates the need for settling ponds which typically require extensive maintenance, consume labour resources, and incur significant costs.

“Tackling the most challenging of materials is our expertise,” said CDE’s business development director, Darren Eastwood. “We’ve poured over 30 years of engineering excellence into the development of the ProPress. We’ve listened to and worked alongside our customers around the globe to design a solution that is adaptable to their needs, be they in the waste recycling or natural minerals processing sectors.

“Those needs were clear: sustainable water management was key to minimise fresh water dependency and maximise water recycling, all while improving processing capacity, reducing operating costs, and minimising maintenance downtime. The ProPress is our response to all of this and more and it is already delivering for our customers. By the end of the year, the ProPress will be found on eight plants across three regions, processing around 1000tph of material.

“Our most significant product launch in recent years, the ProPress really encapsulates CDE’s purpose: to create our best world, a ton at a time. It represents a constant push for improvement to make our equipment, our customers’ operations, and the sectors we operate in more efficient and less wasteful. We’re very pleased to finally bring this latest innovation to the wider market to help maximise the availability of our natural resources and reduce the industry’s waste burden.”

The updated range of JCB 3CX Backhoe Loaders is set to arrive on South African shores this July, promising to build on the brand’s popularity with enhanced features aimed at delivering improved comfort, versatility, and productivity, thereby reducing costs and boosting efficiency

Bell Equipment sales product manager for JCB products, Massyn Jansen Van Vuuren, commented, “This new model range will replace the existing JCB 3CX Eco, 3DX and 3CX Global product lineup. The new cab makeover is the most noticeable change and is bound to impress. The striking new design uses high quality moulded plastics, and the pillars and roof are light grey in colour to give a lighter and more spacious feel.

“Most importantly the new cab places a huge focus on operator safety, comfort, and ease of operation. For example, the loader lever has been simplified to operate like a wheel loader. The 3CX range now has a single lever loader control incorporating an F-N-R directional switch so an operator can control the loader and transmission with one hand. In addition, there is a proportional switch on the side of the lever to operate the 6-in-1 bucket, which further reduces the effort needed to operate the machine.” 

Enhanced features

The new EasyShift transmission with 'kick down' comes standard across the range, simplifying gear changes via a rotation of the F-N-R directional lever next to the steering wheel. The kick down switch, located on the floor, allows operators to shift from second to first gear for added power during loading or site work."

“All cabs are ROPS/FOPS certified and the seat rotation area is larger to give the operator more room, which together with improved cab sealing to keep out water and dust, creates a cleaner and more pleasant workspace. There is also improved visibility to the working area behind the machine,” remarked Massyn.

In addition, the 3CX Plus model introduces a high-performance HVAC air conditioning system with 21 adjustable air vents strategically positioned around the front console, ‘B’ pillar, and rear of the machine, optimising comfort and demisting performance. The 3CX features a standard fan mounted on the B pillar."

Under the hood, the JCB 3CX range benefits from enhanced hydraulic efficiency due to new standard variable displacement piston pumps across all models. The larger pump provides 150lpm, a 39% increase over the previous model, allowing for reduced engine speed while maintaining productivity, effectively cutting fuel consumption. Moreover, the variable flow pump operates on demand, reducing engine load and further improving fuel efficiency.

The Plus and Pro models feature a standard Smooth Ride System for improved road handling and can be equipped with a versatile 6-in-1 shovel, optionally fitted with flip-over forks for increased functionality. “The 6-in-1 shovel can be used for dozing, loading, digging, grabbing, spreading, and grading while the optional flip over forks are ideal for machines that will double up as a forklift for pick and place activities around the work site and to unload vehicles,” he added.

Lighting has been upgraded with six LED work lights replacing halogen lights. Front-mounted adjustable LEDs and rear-mounted LEDs, two of which are adjustable, enhance nighttime visibility. A 'guide me home' light system keeps work lights illuminated for 30 seconds after the ignition is turned off, aiding safe exit from the machine and worksite during nighttime operations.

Other standard features include an in-cab boom lock, front and rear wash/wiper functions, Return To Dig function, electronic throttle control, Bluetooth radio and USB ports, front and side LCD display, adjustable steering column, and a battery isolator key for electrical isolation during maintenance.

"All in all, the new 3CX range has a machine to suit all requirements and we expect these new machines to add real value and strengthen JCB’s position as the world’s leading brand of Backhoe Loaders. We have a fleet of units that will be used across the country to familiarise customers with the new range and the improvements, so we encourage customers to contact their nearest Bell dealer and experience the machines for themselves,” concluded Massyn.

Africa is home to sizeable reserves of the world’s critical minerals. (Image source: Adobe Stock)

UN Trade & Development (UNCTAD) leaders have explored the potential for Africa to become a competitive hub for green industrialisation at an event held in Addis Ababa, Ethiopia

The gathering was a pre-event for the organisation’s 60th anniversary in Geneva, Switzerland, and was held under the theme of ‘Maximising Africa’s Potential: Leveraging Demand for Critical Minerals to Boost Inclusive Growth and Sustainable Development’. Here, senior leaders such as Rebeca Grynspan, UNCTAD secretary-general, made clear how critical minerals will be fundamental to the energy transition and can be catalysts to lift millions out of poverty and create a fairer world. This opportunity is particularly ripe for the African continent, which is home to sizeable reserves of the world’s critical minerals including 55% of cobalt, 47.65% of manganese, 21.6% of natural graphite, 5.9% of copper, 5.6% of nickel, 1% of lithium, and 0.6% of iron ore globally.

However, in order to realise this, Grynspan said the world must break free from the past and reject the extractive model that has kept resource-rich nations dependent and poor. “Instead, we must embrace a new paradigm that prioritises domestic value addition, fosters regional integration and empowers local communities,” she remarked.

A competitive Africa

Antonio Pedro, the UN Economic Commission for Africa’s deputy executive secretary, contributed his voice here, surmising how adding value to critical minerals in Africa could help make the continent a competitive hub for green industrialisation.

“Imagine the potential if African minerals are processed into African batteries, installed into African cars that are driven across the continent and the world,” he commented. “This would accelerate the deployment of renewable energy and the electrification of transport systems on the continent, create decent jobs and make Africa a competitive hub for green industrialisation.”

However, Pedro warned that the mining boom that does not deliver benefits across society “will leave us back at square one” and called for justice and equality in how minerals are harnessed in the global energy transition. He was joined in this sentiment by The African Union Commission’s deputy chairperson, Monique Nsanzabaganwa, who called for the right policy mix and fair international structure and systems – ones that do not threaten African nation’s efforts to increase and enhance beneficiation and value addition as some do currently.

“It wouldn’t make sense to not trust our continental certification systems and instead condition Africa’s minerals to go hit another certification system just to come back to us for value addition or trade among ourselves,” Nsanzabaganwa said.

Seizing the opportunity

According to UNCTAD, African countries generate only about 40% of the revenue they could potentially collect from the sizeable minerals reserves under their feet – a narrative that must change if the opportunity is to be realised.

Amid current global crises, limited fiscal space, slow growth and high debt, African countries need to maximise the financial and development benefits of these resources, UNCTAD advised. Participants at the event in Ethiopia therefore discussed ways to enhance revenue mobilisation and fiscal administration, boost regional value chain integration and increase investment in infrastructure, skills and innovation to support minerals-based industrialisation on the continent while promoting climate action.
