Manufacturing method of quartz sand
I. Introduction
Quartz sand, as an important raw material for the production of chemicals, is widely used in many fields such as glass, ceramics, casting, metallurgy and construction. With the continuous development of science and technology, the manufacturing method of quartz sand is also being improved and optimized. This article will introduce the manufacturing method of quartz sand in detail, including raw material selection, processing technology, equipment selection and other aspects.
Second, raw material selection
The manufacture of quartz sand first needs to choose suitable raw materials. Generally speaking, quartzite, quartz sandstone, vein quartz and other silica-rich ores can be used as raw materials for quartz sand. When choosing raw materials, you need to consider the purity, grain size, whiteness and other factors of the ore to ensure the quality and performance of the final product.
Three, processing technology
The manufacture of quartz sand mainly includes the following steps:
1. Crushing: Crush the large ore into small particles, which is convenient for the subsequent processing. Jaw crusher, cone crusher and other equipment are generally used for crushing.
2. Grinding: The crushed ore is further ground to achieve the required particle size requirements for quartz sand. Commonly used grinding equipment are ball mill, Raymond mill and so on.
3. Classification: Classify the quartz sand after grinding, and separate the products with different particle sizes. Commonly used grading equipment include spiral classifier, hydrocyclone, etc.
4. Iron removal: Since quartz sand often contains some iron impurities, it needs to be removed. Generally use magnetic separator, flotation machine and other equipment for iron removal.
5. Drying: The manufactured quartz sand is dried to reduce its moisture content and facilitate storage and transportation. Commonly used drying equipment are rotary dryer, flash dryer and so on. Four, equipment selection
In the manufacturing process of quartz sand, it is important to choose the right equipment to improve production efficiency, reduce energy consumption, ensure product quality and so on. The following are some key equipment selection suggestions:
1. Crushing equipment: according to the particle size and hardness of the raw material to choose the appropriate crusher, such as jaw crusher is suitable for crushing the hardness of large pieces of ore, cone crusher is suitable for crushing medium-hardness ores.
2. Grinding equipment: choose the suitable grinding machine according to the required quartz sand particle size and output, such as ball mill is suitable for grinding products with high fine grain size requirement, and Raymond mill is suitable for grinding products with low fine grain size requirement.
3. Classifying equipment: choose the suitable classifier according to the particle size distribution and output of the products, such as spiral classifier is suitable for separating the products with narrower particle size range, hydrocyclone is suitable for separating the products with wider particle size range.
4. Iron removal equipment: according to the iron impurity content and iron removal requirements in the quartz sand to choose a suitable iron removal machine, such as magnetic separator is suitable for removing magnetic impurities, flotation machine is suitable for removing non-magnetic impurities.
5. Drying equipment: according to the moisture content and output of quartz sand to choose a suitable dryer, such as rotary dryer is suitable for drying large particles of products, flash dryer is suitable for drying small particles of products.
V. Conclusion
The manufacturing method of quartz sand involves a number of links and processes, and it is necessary to choose suitable raw materials, equipment and processing technology to ensure the quality and performance of the final product. In the actual production process, it is also necessary to continuously optimize and improve according to the specific situation, improve production efficiency, reduce energy consumption, reduce pollution and other aspects of the indicators, to provide high-quality raw materials for the production of chemicals to ensure.
