Ensure the quality of the mechanical sandstone aggregate: from the source to the whole process of finished products

During the production process of mechanical sand and gravel aggregate, the quality, particle size control, mud content control and finished product protection must be ensured. Adopt advanced equipment to strictly control mining, screening, flushing and other links to ensure stable and reliable quality of gravel aggregate, and provide high -quality building materials for the project.

In the production process of mechanical sand and gravel aggregate, every step from the selection of raw materials to the protection of finished products is very important. This article will explore how to ensure the quality of gravel aggregate from four aspects: material quality control, particle size control, mud -content control, and finished aggregate protection.

1. Strictly screen the source to ensure the quality of mining

Before mining wool, thoroughly remove the coverage layer at the top of the material field to ensure that there are no grassroots and coverage of the mining layer on the surface of the mining layer. In order to avoid the border position covered with mixing the hair due to the sliding of the mining and vibration, it is necessary to complete it at one time and leave a sufficient protective area width. In response to the complexity of mud rock burial depth and high groundwater levels, the drainage canal needs to be tapped in advance to reduce the groundwater level and ensure that the mining is smoothly carried out. At the same time, it should follow the order of low to high during mining, and strictly control the depth of mining to ensure that the thickness of the reserved layer meets the regulations.

2. Precisely control particle size to meet the demand for aggregate

The screening link in the production process of gravel aggregate is the key to controlling particle size. We use advanced crushing equipment and vibration sieves, and with the sieve network of standard pores to ensure that the concrete aggregate produced in accordance with grading quality standards. The specifications of the screen network are selected according to the requirements of the aggregate level, and regular inspections and replacement are checked and replaced to ensure the integrity of the production equipment. Filtering the grading through multi -layer round vibration screens to meet the demand for aggregate particle size in different projects.

3. Effectively control the amount of mud content and improve the quality of osteogenesis

The control of mud content is an important guarantee for the quality of gravel aggregate. We strictly control the inclined corner and raw materials of the sieve network, and are equipped with a stable and reliable flush system. The system adopts the main water pipe and water supply pipe with appropriate diameter to ensure the water supply capacity meets the rinse needs. The layout of the water spray holes is uniform, and the water pressure adjustment is appropriate to ensure that the water can evenly cover the entire screen. By adjusting the quantity, interval and water outlet direction of the water spray holes in time, it is best to ensure the best.

Fourth, carefully protect the finished aggregate, prevent quality damage

In the process of transportation and storage, the finished aggregate needs to take a series of protection measures. When the sieved sandstone aggregate is transported to the finished material stack through the tape machine, a quarantine wall is set for partitioned stacking to prevent mixing. The product signs are set for the stacking land of the finished product. At the same time, the construction of a blind ditch drainage system to ensure that the aggregate that is washed quickly dehydrates and meets the water content requirements of concrete production.

In summary, the production process of mechanical sandstone aggregate must strictly control the quality, particle size, mud content, and the protection of the finished aggregate. Through the implementation of these measures, we can ensure that the quality of gravel aggregate is stable and reliable, and provides high -quality building materials for various projects.
