The main component of limestone is calcium carbonate, which has a wide range of sources, diverse uses, and relatively low cost. Generally, in the process of use, it needs to undergo deep processing such as crushing, crushing and grinding before it can be applied to all lines. Lime and limestone are used in large quantities as building materials, which are commonly used as raw materials in the cement production process industry and are also important raw materials in many industries. In the past two years, whether it is tailings treatment or cement production, the limestone production line has become an important form of stone production in stone production. The main products involved are limestone and limestone powder. The use of limestone processing mechanism sand can effectively increase the yield of limestone lump ore, reduce the amount of limestone waste residue, and have obvious energy-saving effects.

Advantages of limestone sand making:

Limestone machine-made sand is made of waste gas, waste residue, stone powder and other waste gas from limestone market through mechanical crushing, screening and water washing. Limestone machine-made sand has the following advantages:

1. Machine-made sand can effectively and stably control sand particles and other technical indicators in accordance with national standards and engineering quality requirements to meet engineering technical requirements.

2. The fineness specification of machine-made sand can be adjusted. According to the needs of the project, the fineness specification particles of the machine-made sand machine can be adjusted by combining the advantages of raw materials and the requirements of concrete.

3. The machine-made sand has multiple diamond-shaped corners and a rough surface, which is beneficial to the bonding of cement and other cementing materials and to the improvement of concrete strength.

4. The production of machine-made sand can be combined with the production process of crushed stone, which is beneficial to the comprehensive utilization of good mineral resources and reducing pollution, thereby greatly reducing the production cost of machine-made sand.

Limestone is an industrial rock with a wide range of uses and a large amount of use. It is widely used in construction, building materials, environmental protection, agriculture, etc. The use of limestone to produce machine-made sand has been promoted and applied in the industry. In our company, there are professional technical personnel to design the production line for users reasonably, and match with a more complete set of production line equipment to ensure that the user’s investment is reduced and the value of income is rising.
