Hot Mix Plant

We stand as prominent manufacturers and suppliers of Mobile Hot Mix Plants in India. Our products undergo rigorous quality checks and are crafted using top-quality raw materials within our advanced manufacturing facility. Furthermore, we provide the option of customizing these mobile hot mix plants to match the specific needs of our valued clients.

A drum mix plant, also known as a “Hot Mix Plant,” is a vital part of making asphalt. It’s like a big mixer that combines different-sized rocks with hot tar to create hot asphalt. Coninfra offers various sizes of these plants, from small ones that make 20 TPH to large ones that produce 150 TPH.

What makes Coninfra special is that we use modern technology, and we can customize the plant to fit what our customers need. That way, it’s reliable and can do the job just the way our customers want. Our plants are tough and easy to use. You can even make them run automatically, and if you need it, we can add extra technology called PLC SCADA to match your specific needs.

Hot Mix Plant Process

The Hot Mix Plant process is a key part of producing the asphalt used in road construction. It begins with various types of rocks, including sand and gravel, stored in separate bins. These rocks are then heated and dried in a special oven, removing any moisture. Once dry, they’re mixed together with hot bitumen, a thick, sticky form of petroleum, in a large mixer. The heat ensures a strong bond between the rocks and the bitumen, creating a hot, adhesive mixture.

This mixture is stored in a silo to maintain its elevated temperature until it’s needed at the construction site. When the time comes for roadwork, the hot mix is loaded into trucks and transported to the location. There, it’s spread out and compacted to form a solid road surface. As the mix cools and hardens during this process, it provides a durable and reliable road surface. Throughout the entire procedure, rigorous quality checks are conducted to ensure that the mix complies with the required standards and specifications. The Hot Mix Plant process is instrumental in delivering high-quality asphalt for constructing robust and long-lasting roads.
