Process design and equipment of cement aggregate production line

Process design and equipment of cement aggregate production line

(Summary description)At present, the industry cement industry is in the form of transformation. In the face of the booming aggregate market, many cement companies in the industry are eyeing them. Many large cement companies have entered the aggregate industry, and a large number of key cement companies are following closely behind. It is entering or planning to enter the aggregate industry to realize the competitive advantage of the whole industry chain. Cement enterprises have quickly established themselves in the sand and gravel industry, and in order to comply with the development of the industry situation, the construction of high-quality sand and gravel aggregate production lines with "new technology, low energy consumption, and high quality" is imperative. So how can cement enterprises' aggregate production line process design How to realize the construction of high-quality sand and gravel aggregate production line?

At present, the industry cement industry is in the form of transformation. In the face of the booming aggregate market, many cement companies in the industry are eyeing them. Many large cement companies have entered the aggregate industry, and a large number of key cement companies are following closely behind. It is entering or planning to enter the aggregate industry to realize the competitive advantage of the whole industry chain. Competitive Advantage.

Cement enterprises have quickly established themselves in the sand and gravel industry, and in order to comply with the development of the industry situation, the construction of high-quality sand and gravel aggregate production lines with "new technology, low energy consumption, and high quality" is imperative. So how can cement enterprises' aggregate production line process design How to realize the construction of high-quality sand and gravel aggregate production line? What about building?

The sand and gravel aggregate production line system generally includes several units: primary crushing unit, semi-finished product storage unit, medium and fine crushing unit, screening unit, finished product storage unit, loading weighing system, water supply and water treatment unit, electrical automation system, spare parts and repair center. These are more detailed sand and gravel aggregate production line systems, so what about the process design of high-quality cement enterprise aggregate production line?

1. The high-quality sand and gravel aggregate production line should first determine the stone material

In the aggregate production line of cement enterprises, the quality of aggregate is different even if the equipment and processing technology are exactly the same with different lithology. Taking needle flakes as an example, compared with limestone and granite, the difference in needle flake content in the finished aggregates after processing between the two can be more than 7%. Even if they are both granites, the lithology of the two different places is different, and the difference in the content of needle flakes may reach more than 10%. When the lithology has been selected, whether the ideal high-end high-quality aggregate can be obtained depends on the selection of the processing technology.

2. Innovative design and processing process of aggregate production line

Aggregate products can generally be divided into 25-15mm, 15-10mm, 10-5mm, and 5-0mm (which can be adjusted according to market demand). Among them, it is hoped that the higher the proportion of 25-10mm, the better, and the smaller than 0.075mm in 5-0mm. The less stone powder the better.

The jaw crusher + reverse crushing two-stage crushing process adopted in the process design of the aggregate production line of some cement enterprises. In fact, in order to obtain the best aggregate gradation, the proportion of 25-10mm aggregate is maximized, and the stone powder is minimized. Multi-stage crushing is optional. Although the choice of multi-stage process has advantages, its shortcomings also exist, because the use of multi-stage crushing and screening operations, auxiliary equipment such as belt conveyors, dust removal facilities, and floor space are all unfavorable factors. Innovative design can reduce these disadvantages.

In general, equipment and processing technology are closely integrated and should be considered as a whole. Since multi-stage crushing is beneficial to aggregate grading, three-stage crushing is generally recommended, namely primary crushing + medium crushing + fine crushing.

3. High-quality sand and gravel aggregate production line equipment should be reasonably selected

According to the lithology of the raw materials, in order to ensure the production of high-end high-quality aggregates with good grain shape and grain gradation, the types of processing equipment should be reasonably selected.

Selection of primary crushing equipment for sand and gravel aggregate production line: The main purpose of primary crushing is to crush large stones (1000mm) to a particle size (less than 300mm) that can be easily transported by conveyor equipment such as belt conveyors. Jaw crushers can be selected according to specific conditions. .
