Recycling & Waste Management Cleaner waste adds value
Grundy & Co increases recycled product portfolio following investment in construction and demolition recycling plant from CDE
A new washing plant for the recycling of construction, demolition and excavation waste has allowed Grundy and Co to add significant value to its recycled sand and aggregate products. The company is located in Widnes and operates from a 9 ½ acre site. Managing director, Kevin Grundy says this new recycling plant is the latest development aimed at allowing the company to continue to expand. “This new washing plant represents the best technology currently available for the delivery of top quality recycled sand and aggregate products,” he says. Grundy and Co offers a range of services including bulk excavation, specialist waste removal, industrial and commercial demolition and contaminated land removal and disposal. Grundy and Co previously operated a dry crushing and screening process and it was the limitations of this process which prompted them to opt for the new washing plant. Sean Parry, operations manager with Grundy and Co played a major role in the specification of the CDE washing plant which he believes gives the company a significant advantage over other operators in the local area. “Cleaner, washed products automatically create a higher level of confidence in the quality of the product from our customers,” he says.
The washing plant includes a variety of treatment phases and Grundy and Co is the first company to benefit from a comprehensive research and development project undertaken by CDE over the last 18 months, as explained by CDE project manager for this latest installation, Sean Kerr. “The evolution of our recycling plants is clear for all to see on the plant for
Grundy and Co. We have put a lot of work into the development of a suite of modular components within the system which allow for modifications to be made with minimal interruption to production.”
It is often the case with large turnkey plant installations, such as the one at Grundy and Co, that while the individual plant components performance is beyond dispute, problems often arise with the integration of all these individual components into one synchronised system.
Working in harmony
“A group of eleven great players doesn’t necessarily make a great team,” says Sean Kerr. “Likewise, while our individual plant items are all great products the key to success is ensuring that they all integrate efficiently and work in harmony with each other.” It is here that the focus on transfer point technology bears fruit for CDE and its customers. At every point where material is transferred from one processing phase to another the focus is on the efficient transfer of this material minimising spillage and wear.
The feed hopper on the plant comes equipped with an integrated belt feeder. This is the same belt width as on the transfer conveyor meaning that there are no choke points for sticky material. There are also polyurethane wear pads at the transfer point between the hopper and conveyor which reduces the lifetime cost of ownership of the processing system. This focus is retained throughout the plant with material passing over either rubber or polyurethane in all the wear areas of the plant – the elimination of contact between the material being processed and steel minimises wear and increases the working life of the machine. For those used to the operation of independent mobile crushing and screening plants the introduction of a turnkey plant can be daunting. CDE is more than aware of this and has developed a project management system designed to give its customers the comfort that the project will be
