Stone aggregate is a very common material in building materials. It is usually mixed with sand and cement in corresponding proportion to make concrete. It is widely used in house construction and paving roads. People are familiar with coarse aggregate stone and fine aggregate sand according to particle size, but they are very unfamiliar with high and common materials. This paper introduces the configuration of high material and common materials and high aggregate stone production line.
1. What are high material and common materials? How to distinguish?
High material and common material are a kind of classification of stones, both belong to sand and gravel aggregate. In some engineering projects with high quality requirements, different stone materials such as 05, 12 and 13 will be selected according to the use requirements. At the same time, high material and common material stones are also required in some cases. In daily life, the distinction between high material and common material stones is not strict, which can be distinguished by experimental test. It is mainly specified from the crushing value and mud content technical indicators of stones, which can be described in the following instructions.
01. Technical indicators of crushing value: < 21 for high materials, < 23 for common materials, > 23 for direct return.
02. Technical index of mud content: <1.0 for high materials and < 1.5 for common materials. The crushed stones above 1.5 can be washed with water, and can be used in batches according to ordinary high-grade materials after meeting the requirements of crushing value and mud content.
2. How to configure the high material gravel production line? What are the key points?
Compared with ordinary stones, high-material stones have more strict requirements on the technical indicators of finished stones. How to configure equipment to produce more high-material stones in the production of stone aggregate? What are the key points to note? The following is your answer.
01. Configuration of fixed high material gravel production line.
Applicable raw materials: granite, basalt and other medium and high hardness materials.
Finished product specification: 05, 12, 13 stones.
Equipment configuration: vibrating feeder (uniform feeding), jaw crusher (coarse crushing), cone crusher (medium and fine crushing), circular vibrating screen (screening and grading), stone washer (cleaning finished products), belt conveyor (conveying materials).
Key points: the selection of metamorphic rock, igneous rock and other rocks can ensure that the crushed value of the produced stones meets the index; Fully screen and grade the finished crushed stone to ensure the output of reasonably graded stones; In case of cross production of high material and common material stones, the finished product stockpile shall be stored separately.
02. Configuration of mobile high material gravel production line.
Applicable materials: basalt, bluestone, limestone, etc.
Finished product specification: 12, 13 stones.
Equipment configuration: mobile crusher (jaw crusher, impact crusher, cone crusher, hammer crusher, fine jaw crusher, vibrating screen, etc. can be selected as required).
Key points: the mobile crusher can be transferred flexibly. In case of different types of materials, pay attention to cleaning the crushing chamber before operation; Configure high-frequency vibrating screen to screen and classify materials, and transfer high or common stones in time; In case of high mud powder content, it is also necessary to configure a stone washing machine or send it to the stone washing plant for cleaning.
The complete configuration of the high material stone production line pays particular attention to the screening and stone washing links. At the same time, there is also some attention to the selection of stone crushers. The equipment configuration price of the fixed high material stone production line is lower than that of the mobile one, and the production advantages are different. If you need more accurate configuration price of high material stone production line, you are welcome to consult online.
