Waste stone is applied to reinforcement grout after grinding by milling machine

Waste stone refers to all the stone as raw material waste, trimmings and stone tailings, etc., from a wide range of sources, low prices, transportation and processing process is convenient. And reinforcement grout is used in construction, bridges, ground and other project facilities for secondary grouting, reinforcement of raw materials, solid also known as reinforcement project special reinforcement material. Between the two of them rely on the mill will be closely linked, complement each other, each take what they need, here we come together to learn more about it.

Waste stone here needless to say, we are more familiar with, everywhere, at present on the waste stone, its main role is to be used to fill the low utilization of resources, some even in the mining area around the heap processing, on the surrounding water quality, good land, the air are seriously polluted, can be said that early on the disposal of waste stone is very inappropriate, not only a waste of resources, but also cause huge environmental pollution problems, waste stone recovery Processing is imminent.

Reinforcement grout is used in engineering construction to improve the strength of concrete additive materials, its main role is to reinforce the structure of the repair project, the role of the aggregate micro-filling, since as a secondary filler reinforcement materials on its performance indicators naturally have strict requirements, its mobility, expansion rate, early and final strength, and setting time and other important indicators to become a measure of the reinforcement of the important criteria for the consideration of the grout. Reinforcement grout in the concrete project plays a significant role, far-reaching significance, in the continuous exploitation of resources close to the shortage of the present, how to realize the rational and efficient use of resources when the development of an important direction. After a variety of tests and production experience, the waste material stone by Raymond mill and other grinding equipment used in reinforced grout play a huge role in the grinding of stone powder than the larger the area, that is, the greater the fineness, the greater the strength of the sand, the greater the mobility. Waste stone in the reinforcement grout to help supplement the raw material at the same time, but also to realize its own value. Its economic value is mainly reflected in the following two points:

1. Stone powder is a kind of inert admixture, does not participate in the hydration process of cement, only in the reinforcement grout to play the role of aggregate micro-filling, that is, not to destroy the performance of the original reinforcement materials;

2. Stone powder is involved in the hydration process of cement, which helps to improve the working performance, mechanical properties and durability of reinforced grout.

However, because of the many types of stone, the nature of the stone varies greatly, in the choice of grinding machine for different stone need to be careful.

1. Stone recycling need to pay attention to the classification process, with all the stone but the performance difference is large, there are differences in hardness, density and other aspects of the classification of recycling is more convenient for the later mill grinding process.

2. Different kinds of stone do not grind at the same time, because different hardness materials in the grinding chamber crushing situation is different, for example, limestone, cobblestone two different materials if put into the grinding chamber at the same time to grind, it will cause the lime powder fineness is too fine, cobblestone is too coarse, the fineness of the powder is not uniform imagination, the mill productivity, wear and tear also has an impact.

3. The choice of mill type model is strictly based on the nature of the stone, customer demand, do not generalize.

4. On-site trial is a better way to protect the interests of customers and mill manufacturers, because even if the same material or due to geographical differences there will be differences, trial and is the most foolproof method.
