In recent years, with the continuous advancement of infrastructure construction, the demand for sand and gravel, as the core raw materials for concrete production, has continued to rise. However, sand and gravel resources are non-renewable, and over-exploitation has led to increasingly prominent issues of resource scarcity. Various regions have introduced policies to control sand and gravel mining, further exacerbating the tension in sand and gravel resources. The market price of sand and gravel continues to rise, posing significant cost-reduction pressure on mixing plants.
For concrete mixing plants, the cost of sand and gravel raw materials accounts for a significant proportion of the total production cost. Rising sand and gravel prices directly drive up production costs and compress the profit margins of enterprises. How to save sand and gravel raw materials and reduce procurement costs has become an urgent issue for many concrete mixing plants.
The sand and gravel separator precisely meets market demands. With its efficient sand and gravel recycling technology, it turns waste concrete into a valuable resource, saving precious sand and gravel resources while helping mixing plants reduce raw material procurement costs. It achieves both increasing revenue and reducing expenses, as well as reducing costs and increasing efficiency. Tailored specifically for the treatment of waste concrete, it can quickly and thoroughly separate sand and gravel from the slurry in waste concrete. The recycled sand and gravel undergo professional cleaning and screening to remove the cement slurry and fine impurities attached to the surface. The cleanliness meets the standards for concrete production and can be directly reused in production, realizing the circular utilization of sand and gravel resources.
Taking a medium-sized mixing plant as an example, 10-20 tons of recyclable sand and gravel can be obtained from the waste concrete generated daily, and 3,000-7,000 tons can be recycled annually. Based on the current market price of sand and gravel, the annual raw material procurement cost can be saved by 200,000-500,000 yuan, significantly reducing the operating costs of the mixing plant.
Meanwhile, recycling sand and gravel from discarded concrete reduces the piling of waste materials and alleviates environmental pressure, aligning with the national policy direction of resource recycling and facilitating green and sustainable development for mixing plants. In the context of a shortage of sand and gravel resources and rising prices, sand and gravel separators have become crucial tools for mixing plants to increase revenue and reduce costs, helping enterprises reduce costs, enhance competitiveness, and achieve healthy development in the fierce market competition.
