Stone processing produced by the use of stone slag stone powder

 
As stone industry growing, stone processing enterprises of surplus (scraps, leftover material), more and more, especially after the stone saw cutting of stone powder, although adopted circulating water treatment and secondary precipitation, accumulate over a long period, wastes, limestone mountains, long time not only tie up the land, and serious environmental pollution, has now become a major disease which restrict the development of the enterprise for a long time.
And with the deepening of the concept of resource conservation and environmental protection, the state has put forward higher requirements for the environmental protection of enterprises.Stone association in accordance with the requirements of the national environmental protection and related authorities also held a number of seminars, will increase the development and protection of natural resources in the future, which fully shows that: control pollution, optimize the environment, save resources, is the current stone industry to speed up the adjustment of industrial structure, change the mode of economic growth.
So how to produce stone waste, waste residue, stone powder waste into treasure?
Although China's stone industry on the use of stone waste research time is not very long, but China's stone practitioners have developed a variety of stone waste, waste residue and stone powder utilization methods.
The following introduces the main domestic stone waste, waste residue and stone powder utilization:
1. Used for the production of artificial sand, sand used for casting and linoleum demagnetization powder of waterproof material, etc., used for steel casting, easy demagnetization and smooth casting.
2. Chemical fillers and paint fillers, architectural decoration painting, etc.
3. Instead of soda, used for tanning, stone powder instead of baking soda can be used for leather acid, instead of baking soda can increase the baking alkalinity.This technology can reduce labor intensity and improve economic benefits.
4. As a fuel booster and desulfurizer for domestic coal, 5%-10% marble powder is added into the coal for production, which can not only save the coal, but also help combustion, reduce the emission of sulfur dioxide gas, and improve the indoor and outdoor environment.
5. Add stone powder when making electrode, can play the role of slag making, to prevent the melting pool and arc into oxygen and nitrogen.
6. The waste rock slurry produced by various processes in stone processing can be used as cement raw material and asphalt pavement filling material after precipitation, dehydration and drying, and can also be used as chemical fuel filling agent.
7. Add appropriate cement, curing agent and small stones into the stone slag and press the embryo through stirring.It can be made into new wall material.
Thus it can be seen that the comprehensive utilization of natural stone waste has a very good prospect.In the stone industry as a whole into the small profit stone today, as long as be good at innovation, also can produce a good marginal effect.
