What are the application methods for turning stone waste into treasure?

There are many kinds of stone waste, including the following types: stone waste, crushed stone slag/waste produced by stone processing plants, marble waste powder slurry powder, marble blocks, etc. The production and use of decorative stones in the world are basically increasing every year, but the waste products produced in various shapes and specifications are also increasing. This situation puts an economic burden on the ecological environment, human health and related enterprises. , has brought worrying negative impacts. So far, scientific researchers in some countries around the world have explored how to utilize waste materials generated by the stone industry in various industrial activities, including stone mining waste, stone waste, and stone waste slurry waste generated by the stone processing industry, especially the latter.

The uses of stone waste are as follows:

1. Production of concrete aerated blocks from waterproof stone waste:

It includes a brick body and a convex strip provided on the top of the brick body. The convex strip is provided with a plurality of arrays along the length direction of the convex strip. The utility model provides a locking block, and the first locking block The shape of the first locking slot is adapted to the shape and the position is corresponding; one end of the brick body is provided with first locking slots distributed in second rows, and the bottom of the brick body has a plurality of first locking slots.

The second card position block corresponds to the hot state of the precision long cabinet, and the position is very corresponding; the hanging structure of the Farley card position block is consistent with that of the second card position block. And there is no second blocking block protruding from any phase slot at the other end; the center distance between the blocking slots is greater than the thickness of the brick body; its structure is novel, easy to match, combine and install, and can significantly speed up workers’ wall construction speed and improve production efficiency.

2. Comprehensive utilization of granite stone waste:

Granite powder waste is used to produce construction wall bricks. The application possibility of granite waste in the production of building walls and floor bricks; granite waste is used as the main raw material to prepare microcrystalline glass, etc., which provides a broad prospect for the resource utilization of granite waste. application space.

3. Use stone waste to produce polyester artificial marble:

The waste stone powder generated in the process of stone production has been studied for secondary reuse. The experiment resulted in the optimal formula with a waste stone blending amount of 58%. Research and testing showed that all properties of the artificial marble prepared using this formula met the standards, so it can be used in production. The implementation of this project can consume a large amount of waste rocks every year, thereby reducing the occupied area of cultivated land in Yunfu City and improving land utilization. It can also solve the problem of environmental pollution caused by accumulation. On the other hand, this technology improves the secondary value-added of stone waste. The finished product has good performance, low cost, simple production process, good economic and social benefits, and has broad application prospects.

4. Methods of using stone waste to produce building materials:

After crushing the stone waste, it is screened into: fine sand, medium sand, coarse sand and gravel. According to the different requirements of building materials, adjust different proportions and mix with cement, lime, and water evenly to make masonry mortar, process prefabricated panels or pieces for construction, cast floor reinforced concrete frames and layers, and lay highway pavements. , can produce building blocks, etc. Recycling stone waste into resources reduces land occupation, eliminates environmental pollution and saves energy. It has low production costs regardless of stone types and is not subject to technical limitations. It has a wide range of applications and can maximize comprehensive utilization.

5. Three ways to reduce stone waste:

The stone industry has now reached a stage where it must re-examine its development prospects. On the one hand, every manufacturer is facing the following new economic problems: increased competition and falling prices; high investment in processing equipment brings high production costs;

High investment measures to protect the environment; on the other hand, customers’ growing demands for product quality, quality stability, production capacity, etc. require more effective grinding and polishing equipment, as well as new chemical Process product system.
