Lime production: The lime project first requires the establishment of a lime production line, which usually includes steps such as limestone mining, crushing, grinding, and calcination. The lime production line needs to consider factors such as raw material sources, production processes, and equipment selection. Lime sales: The produced lime needs to enter the market through sales channels, which requires establishing a sales network, expanding market channels, and improving product awareness and competitiveness. Lime application: Lime, as a widely used building material and industrial raw material, is widely used in fields such as construction, chemical industry, metallurgy, agriculture, etc. In the field of construction, lime can be used for plastering, masonry, coatings, etc;

The vertical kiln project refers to the process of constructing a vertical kiln, which is an equipment used for producing cement. The construction of a vertical kiln project mainly includes the following steps: design and preparation: Before construction, it is necessary to design the vertical kiln, including determining its size, shape, materials, and structure. At the same time, pre construction preparation work is also required, such as cleaning the construction site, preparing construction equipment and materials, etc. Installation foundation: The foundation of the vertical kiln needs to be sturdy and stable to ensure its stability and safety. Therefore, during construction, it is necessary to install foundations, usually using concrete foundations or steel structure foundations.

Solid waste refers to solid, semi-solid, and gaseous items and substances placed in containers that have lost their original utilization value or have been abandoned or abandoned despite not losing their utilization value, as well as items and substances that are required by laws and administrative regulations to be included in solid waste management, generated during production, daily life, and other activities. Liquid waste that cannot be discharged into water bodies and gaseous substances placed in containers that cannot be discharged into the atmosphere. Due to their high level of harm, they are generally classified under the solid waste management system.

Cement engineering is an indispensable part of modern construction, involving the production, use, and research and development of cement.
In terms of production, cement engineering mainly focuses on the production process of cement, including the selection, processing, mixing, clinker preparation, and packaging of raw materials. The research focus in this field is on how to improve the production efficiency of cement, reduce costs, and improve product quality
In terms of usage, cement engineering mainly focuses on how to mix cement with other materials to form concrete, which is used for the construction of building structures, pavements, and other infrastructure. The research focus in this field is on how to improve the strength, durability, and performance of concrete.

Low temperature technology: Low temperature technology refers to the use of various low-temperature refrigerators, low-temperature materials, and low-temperature insulation technologies to achieve low-temperature environments or obtain low-temperature objects. Low temperature technology is widely used in scientific research, industrial production, medical and other fields. Low temperature materials: Low temperature materials refer to materials that maintain good performance in low temperature environments. For example, low-temperature liquids such as liquid air, liquid nitrogen, and liquid helium are widely used in industry and scientific research.
