A New Recycling System for the Better Handling of Road Grit Introduced

Any construction or road building project produces a great amount of waste, and this is why we have various machines and equipment that help us deal with this road waste, grit, and refuse. But the UK company Siltbuster has recently introduced a much bigger (and notably more powerful) system for the separation of wet waste in construction and road building sites.

This new system is referred to as The Gritbuster WT-250, and it is an improvement on the company’s existing material separation, recovery, and washing equipment. The Gritbuster is especially useful for the road sweeping as well as fine waste recycling industries, and distinguishes itself by being able to handle approximately 25 tonnes of waste per hour. The system makes use of well-known processes for wet separation, and then separates this waste into various sand and washed gravel products.

What makes The Gritbuster WT-250 different?

One noteworthy aspect of the new Gritbuster is its method of dealing with washing and separating waste. The equipment can be loaded with the raw material with the use of a telescopic or wheeled loader, and then a screw auger is used to deal with both wet and dry feeds. Another distinction of the machinery is its wet trammel, which has been designed to wash and then separate aggregate material whilst virtually eliminating the risk of sand contamination with organic material. The result is a much cleaner and purer sand.

Along with a wet trammel and screw auger, the Gritbuster is equipped with a density separator making use of hydraulic power to separate and distinguish coarse aggregates from organic material or plastics. As a matter of fact, this density separator is truly what makes The Gritbuster stand out, as it is capable of separating larger materials by the use of density rather than just actual size. What this means is that stone and other heavier materials can be recovered in a much cleaner form. Lighter materials such as wood, paper, or plastic can then also be recovered more easily for use in other recycling processes.

The recycling benefits

With The Gritbuster, recovered gravel, sand, and other aggregates can easily be reused, either as a secondary aggregate or a non-structural filler, as long as the product is processed under WRAP guidelines. Another benefit offered by the new Gritbuster system is the fact that the amount of fresh water used is reduced, since the system operates in a closed loop, particularly when combined with the company’s own filter press.

Other benefits to the new Gritbuster

Along with the above-mentioned benefits, The Gritbuster also features a more compact and trim design that allows it to be easily installed on an existing site and integrated with existing or current waste treatment processes. But perhaps the greatest benefit brought by The Gritbuster is the fact that materials which would have just been dumped in landfills can now actually be recovered and recycled, and even sold as a separate product.
