In the field of modern road construction and maintenance of asphalt recycling material milling material and excavation material is a common source of waste material, they are derived from pavement milling operations and foundation excavation works.
Milling material mainly refers to the waste asphalt concrete generated by the removal of old pavement by milling machines during the repair and reconstruction of highways, bridges, and other facilities; while excavation material includes a variety of soils, rock mixtures, and other mixed wastes excavated during construction and municipal projects. These two types of materials are large in quantity and contain recyclable components, how to choose an effective and environmentally friendly processing equipment.
Introduction of Double Tooth Roll Crusher
For this reason, the double tooth roll crusher, which is specially developed for the characteristics of milling and excavation materials, has come into being. This equipment makes full use of the core advantages of double-tooth roll crushing technology, with its strong targeting and excellent processing results, has become the ideal tool for processing these two types of materials.
The design concept of the double roll crusher closely combines the characteristics of milled and excavated materials. Its inlet can accept materials with a maximum particle size of up to 30cm, which is highly adaptable and can easily cope with large pieces of waste asphalt concrete in milling materials and mixed lumpy materials in excavation materials. Its double-drum structure with specially designed crushing teeth enables precise control of the discharge size, ranging from 1 mm to 30 mm, in line with the requirements for recycled aggregates and backfill materials. A wide range of models are available, with capacities ranging from 5 tonnes per hour to as high as 2,000 tonnes per hour, including more than 10 model configurations, which can be flexibly adapted to the needs of various large, medium and small projects.
The double roll crusher adopts a flexible crushing process, which is capable of crushing the material as strongly as possible, while retaining the original internal structure of the material as much as possible, so as to prevent over-crushing and affecting the performance of the recycled asphalt mixture. The operation and maintenance of the equipment is also very user-friendly, simple and convenient, aiming to create a more economical and efficient working environment for users.
