Recycled concrete refers to a new type of concrete obtained by mixing waste concrete blocks with a certain proportion and grading, and partially or completely replacing natural aggregates such as sand and gravel. Different from the preparation of ordinary concrete, the powder produced during the preparation of recycled aggregates (referred to as regenerated micro powder) contains a large amount of hardened cement stone and cement that is not fully hydrated. It has high activity and internal specific surface area and can be used as a blend after treatment. Mixing materials, participate in the preparation of concrete.
Because the regenerated micro powder is mostly made of waste concrete, it has the advantages of convenient material, green environmental protection and economical benefits. It is mostly used to replace cement or fly ash, and is used as a blending material in the production of cement, concrete, mortar and other building materials.
With the introduction of the sustainable development strategy, construction waste reclaimed micro-powder has begun to be valued by people, and it is of great significance for building a resource-conserving and environment-friendly society with broad development prospects.
Processing recycled micro powder, I recommend to you the Guilin Hengda Mining Machinery HD series raymond mill, which can be applied to 200 kinds of stones, such as feldspar, calcite, limestone, talc, barite, rare earth, marble, phosphate ore, kaolin, bentonite, gypsum, Perlite diatomite, dolomite etc. It has the folowing advantages.
1.Reduce the roller and vibrate and improve the production.
2.The increase mechanism of linkage pressure of the rollers, which greatly prolongs the useful life of the equipment and increases the capacity by 20% under the same power.
3.With the original roller assembly, the oiling time increased 6 – 15 times, archive the application of oil once, use for 30-45 days.
4.High efficiency and stability, the ring and roller always contact during processing, the efficiency and stability of the grind are improved.
5.Higher Accuracy powder Classify, without coarseness missing.
6.High production, high qualification rate Low noise and vibration in grinding of the 325-400 meshes.
