Aggregate Washing

At S.E Davis & Son Ltd we run some of the largest centrifuges in the country producing between 15-45 tonnes of clay per hour, and with in-feed rates of up to 250m3 per hour we can tackle the biggest dewatering jobs.  The units are fully mobile, easy to set up, all have built in floculant make up systems and can be fully equipped with all the ancillary equipment you could need including, feed pumps, discharge pumps, clay delivery augers and lime stabilisation units.  We can supply a complete package for your de-watering needs including umbilical piping and pump systems with capabilities up to 2500 meters, sand plants to remove any fine aggregate prior to being fed in to the centrifuge and we also supply generator units mounted on hook lift frames for fast deployment with no craning necessary, they come complete with large capacity bunded fuel tanks to keep refuelling to a minimum and power distribution boards with individual overload and earth leakage protection on each of its 125 or 250 amp outlets.

The majority of our Aggregate Washing Systems are fully mobile and easy to set up. Our mobile, wheeled and Tracked Wash Plants can be set up in around 24 hours. All of our Wash Plants come with an operator to enable the plant to run at its full potential. We can build a bespoke Wash Plant to any specification and to suit any job, an example of this is our newest invention, our tracked Log Washer. This is the first Tracked Log Wash system and was built in our own Workshop by our design and fabrication team. For long term projects we have semi static plants mounted in standard ISO frames for fast deployment.  These frames are extremely fast to erect and require no civils, just a level well compacted surface.  These plants are erected using our mobile cranes that are readily available to move our Wash Plants around the country. Our static Wash Plants can be ready to start washing the feedstock within 48 hours. We do all of the setting up including the lift plans and the haulage using our own transport division. We also employ a team of engineers to enable the setup to run smoothly. We currently run 10 Aggregate Washing Systems around the country which gives us a wide range of experience and knowledge of different materials including sand and gravel, recycled aggregates, quarry waste (scalpings) and quarry dust all of these present a different  challenge and silt content but with our wide range of experience we have the solution to your problem.

We believe that the system is unique since it doesn’t rely on a constant supply of clean water for washing or the need for vast settlement lagoons in which to dispose of the used water. Instead we use a closed system and Water Recycling Unit that allows us to recycle the water in the system. The system is proving very popular for the recycling of road chippings by local authorities and their contractors.

Water Supply – We use a closed system and Water Recycling Unit that allows us to recycle the water in the system.

Water Disposal – With a closed system, our water doesn’t need to be settled to get rid of waste. With recycled water being used, there’s no lagoons required – SE Davis washing plant takes up a very, very small footprint.

Easy Set Up – All our washing plant is mobile, we can fit it onto any site that has some flat, solid ground. From start to finish the plant can be installed in less than 48hrs.

Cost Saving – The reason why councils, road contractors and civils companies love our plant is that it can be installed quickly, will make you money from the recycled product you produce and can be incorporated into a site temporarily without affecting other operations at fraction of the cost of loading out to another site.
