Description

Technical Field

[0001] The invention relates to the technical field of waste recycling, in particular to a production line for comprehensive recycling of low-iron dolomite production waste. Background Art

[0002] As a raw material, low-iron dolomite will produce tailings during the production process. These tailings can be reused after certain treatment. Tailings can be used in combination with cement concrete to produce concrete products with high strength and frost resistance, such as cable tunnels, bridges, pavements, etc. In addition, tailings can also be used to make hollow bricks and aerated concrete to enhance the mechanical properties and thermal insulation properties of the materials. Tailings, as an environmentally friendly, economical and efficient railway ballast material, can not only replace traditional sandstone ballasts, but also effectively reduce the impact of mineral mining on the environment. It is the embodiment of the concept of sustainable development. Since tailings contain high levels of main ingredients such as magnesium oxide and calcium oxide, they can be used as cement additives to improve the hardening quality and mechanical properties of cement, extend the service life of cement, reduce the consumption of energy and raw materials in the cement production process, reduce production costs, and achieve capital efficiency. Recycling of resources, tailings can be used as an excellent filling material for treating domestic and industrial wastewater, can adsorb and decompose harmful substances such as heavy metals, purify water sources and protect the environment. These applications not only realize the reuse of waste, but also help reduce environmental pollution and promote the sustainable use of resources. When these wastes are reused, a comprehensive waste recycling production line is needed. The common low-iron dolomite production waste comprehensive recycling production line on the market will produce a lot of dust when coarse screening of raw materials.

When raw materials and finished products fall on the belt conveyor for transportation, they are easy to impact the belt of the belt conveyor and affect the service life of the belt.
