Resin-bonded Information – Washed, Dried, Screened and Bagged

Washed and Screened

To ensure continuous quality, materials must be selected from reliable and consistent quarries. Over the years we have pioneered the washing, drying, screening and bagging of aggregates to give a range of colours that meet the most demanding of customer’s requirements.

It is important that the products produced are carefully handled during the washing, blending and bagging process to minimise the attrition created when aggregates rub together which can cause a higher percentage of fines in the finished product. Our process is unique in removing more of the fines and dust than other plants can.

Dried

Pre-washed materials are dried in large batches, through rotary driers and then screened to provide superior clean dried aggregates fit for use straight away.

Bagging and Shrink-wrapping

The bagging and shrink-wrapping which effectively seals the product until it reaches its site is done using robotic packing lines that prevent manual handling of the product. Colours of aggregates occur naturally and some variation can be present within a quarry. At Derbyshire Specialist Aggregates we deal with this by holding large stocks which are constantly rotated and blended to control colour consistency to keep any variation to a minimum. This is an important key factor in our quality control and at any time we stock in the region of 20,000 tonnes of materials to ensure consistency of grade and colour.

Manufacturing of standard products is usually carried out in production runs of 100 tonnes or more to ensure high quality and consistent results with all batches.
