Mobile Drying

Mobile Mineral Drying Service

Wet material is difficult to treat and existing treatment options are expensive and only available at fixed locations. The CDT mobile drying plant improves the workability of material making it easier to screen and segregate. The method extends to utility spoil, residues from balancing ponds, gully waste, rail ballast, filter drain media and even soils contaminated with invasive weeds.

The drier has a nominal capacity of 35 tonnes per hour and can use oil or bio-mass as a heat source. The waste material is loaded into the feed hopper using an excavator or loading shovel and the speed of the feed conveyor is controlled by the operator to achieve the optimum output temperature. The material is then fed through a rotary drum which also has a variable speed facility and is discharged via a conveyor to a stock pile or directly into a screening plant. Once the material is dry, valuable minerals are reclaimed.

Bespoke Engineering Design 

CDT has many years of development experience and knowledge in the design and production of heating and control systems for a variety of materials. We can design bespoke equipment to improve your recycling processes and reduce operating costs.

CDT adapts its heating process to meet the needs of each client and to maximise operational efficiency. The drying plant is offered as a mobile unit on a tri axle trailer, on tracks, on a skid or as a static unit. The heating system utilises either a standard oil burner unit, natural or propane gas or bio mass derived from waste wood. An on-board diesel generator or mains connection can be used to power the drum and feed conveyors.

Production can be monitored using a data log to record machine stop and start times and the output temperature of processed material and the data downloaded via a phone link. Additional features are available including alarms, emergency stops and an operator interface.

CDT works with its clients to design the most cost effective and efficient configuration to meet individual requirements.

Aggregate Recycling Consultancy

Mineral and Aggregate Consultancy

The purpose of drying unusable construction waste is to allow the physical segregation of the different fractions and the recovery of valuable materials, for example aggregate and sand.

In addition to drying technology, CDT offer a screening service to isolate inert minerals and crushes them to produce graded recycled aggregates and soil. To support this CDT uses MTS Environmental and its Waste Accountant management system to manage and if required, broker the processed materials.

CDT holds a Part B Environmental Permit to cover the drying and crushing processes at all operating sites. 

To comply with Environmental legislation all activities are covered under a Bespoke WRAP Quality Protocol where ‘End of Waste’ can be demonstrated.

CDT have an established working relationship with a UKAS accredited Materials Laboratory and can provide a sampling and testing service for all materials.

Crushing and Screening Services

CDT helps its clients to find the most expedient methods to recycle aggregate extracted through the mobile drying process into the following products used within construction and engineering specifications:

All quarried materials

Sustainable recycled aggregates

MOT type 1 base crush concrete

6F1/6F2 crushed brick and concrete

6F1/6F2 brick and slag hardcore

SMR stabilised soils

Certificated top soils

All secondary aggregate materials are manufactured in line with current WRAP protocol on your site.

Waste Management Software

If you have a problem with waste disposal CDT will help you to find or develop a solution, that is either, finding a cost-effective disposal route or assisting you in the development of a system for reusing the material.

Helping you manage your waste

CDT uses WasteAccountant.com to provide clients with a fully auditable waste compliance system. CDT will install Waste Accountant within your organisation and train your staff to use the system to maximise resource efficiency. Once WasteAccountant.com is in place you will begin the process of taking full control of waste management within your organisation.

Managing your waste for you

Sometimes companies do not have the necessary resources or expertise to manage waste effectively and prefer third parties to take control over their waste management. CDT can manage your waste/materials on your behalf and will use Waste Accountant to demonstrate full transparency and accountability for any waste management activities undertaken by CDT.
