With the increasing constraints of resources and ecological environment, the basic conditions such as the source of industry, production mode, production scale, product quality and competition objects that the traditional sand and stone industry relies on for survival have undergone major changes, and the future sand and stone aggregate will be built into a resource-saving, resource-reuse and environment-friendly industry.
The construction and development of every city cannot be separated from sand and stone. With the acceleration of urbanization, the demand for sand and stone will continue to grow. It is necessary to stand on the height of ecological civilization construction, correctly deal with the contradiction between mining development and ecological protection, and realize the green development of sand and stone resources.
The green development of the sand and stone industry, that is, in the entire supply chain of construction sand and stone aggregate, comprehensive consideration of environmental impact, product quality, resource efficiency, based on the theory of green manufacturing, sand and stone aggregate production, transport and use of the corresponding requirements.
With the tightening of environmental protection policies, the sand aggregate industry has become more and more the focus of the whole society. On the one hand, the closure of open-pit mines, the shortage of sand and aggregate, the soaring price of sand and aggregate, and the emergency of sand and gravel all over the country, seriously restricting local construction and economic development; On the other hand, illegal sand mining, green mine construction, sand and gravel transportation have been closely paid attention to by local and even central departments, and the social attention of the sand and gravel industry is constantly increasing.
Although the importance of sandstone aggregate is not recognized enough in our country, it is gradually becoming a new strategic mineral. Strategic minerals are mineral resources that have important influence and restriction on national defense security, economic security and sustainable economic and social development. At present, sand and stone as a cheap and indispensable mineral, is among them. In the future, with the increasing shortage of natural sand resources, the importance of sand aggregate is further highlighted.
Adhere to the practice of green mine concept, improve the comprehensive utilization of resources, the mud separator can completely separate the soil and stone, the soil is backfilled, the backfilled mine can be restored and afforested, and the ore can also be effectively used. Medium thick mechanical mobile mud separator, mud separator can also be used to clean the river, easy to move, simple operation, clean sand separation, low operating costs.
The medium thick mechanical mud separator (roller screen) implements the concept of green mine and improves the comprehensive utilization rate of resources. Mud and stone separator is also called roller screen, soil and stone separator, such as thick screen, is our company specializing in the development and production of sand and stone separation heavy equipment. The machine is mainly used for the separation of mud and stone, the separation of sand and stone in the cleaning river, the separation of cuticle and ore in the mine, and the separation of ore before the crusher to improve the output of the crusher.
1, high screening accuracy, high efficiency, single production capacity of more than 1000 tons/hour.
2, in different mines can play conveying, separation, multistage screening and other functions, can achieve a multi-purpose machine.
3. The cutter head is made of thickened high-manganese alloy material with long service cycle.
4, the use of digital frequency conversion technology, simple operation, no card machine does not block material.
