Concrete aggregate material detail for attention

Select the appropriate lining and grinding media is one way to improve work efficiency of in sand production plant. Lined with two effects, one is to protect the cylinder is not worn, on the other hand to prevent the material in contact with iron, to avoid material contamination. Generally used in the lining of the more wear and rules to ensure durable. While increasing the effective volume in the formula into the feeding amount to the same premise, density, hardness, size is a reasonable ratio of grinding media in order to shorten the milling time, while reducing the wear rate of grinding media.
The raw materials used in cement production are widely available in great quantities. Limestone, marl, and chalk are the most common sources of calcium in cement (converted into lime through calcination). Common sources of silicon include clay, sand, and shale. Certain waste products, such as fly ash, can also be used as a silicon source. The iron and aluminum can be provided as iron ore and bauxite, but recycled metals can also be used. Finally, about 5% of cement by weight is gypsum, a common calcium- and sulfur-based mineral.
Determine the appropriate proportion of material, ball, water is important in sand production. A grinding load have a significant impact on the improvement of milling efficiency, loading capacity is too small, the rattle and abrasive material is small, excessive loading, into the feeding amount to reduce the grinding media interactions increase on materials for reduce reactive and abrasive. Grinding media load a certain amount of time each ball into the feeding amount of different milling is not the same, into the feeding amount is too small, are able to shorten the milling time, but daily output is decreased, too much into the feeding amount, the cylinder body remaining less space, reduce the rattle of the grinding media milling efficiency is low.
With all of these raw materials, the distance and quality of the sources have a big impact on transportation energy use. Water is used for washing, and dust generation. Some aggregates that have been used in concrete production have turned out to be sources of radon gas. The worst problems were when uranium mine tailings were used as concrete aggregate, but some natural stone also emits radon. If concerned, you might want to have the aggregate tested by for radon. These are the main points you should pay attention when choose construction aggregates.
