How to control the stone powder content during the operation of a sand and gravel production line?

There are two main methods for controlling stone powder content during the operation of a sand and gravel production line:

1. While ensuring the cleanliness of raw materials, we need to optimize the operation of the sand making machine and screening workshop to reduce the amount of flushing water entering the spiral classifier. This adjustment aims to reduce the content of fine sand and stone powder carried away by the water flow at the tail end of the spiral classifier, thereby improving production efficiency and product quality. By precisely controlling the water volume, we can not only reduce resource waste but also ensure the stability and sustainability of the production process. This improvement measure is of great significance for enhancing overall production efficiency.

2. The tailwater generated in the sand making and screening workshops is collected in the water tank of the sand making machine by the spiral classifier for sedimentation. The sand making machine not only processes sand and gravel but also recovers the stone powder and fine sand lost from the tail end of the spiral classifier during screening and sand making. This recovered material is then sent to the finished sand bin, increasing the stone powder content in the artificial sand and allowing its fineness to be adjusted as needed. This not only improves resource utilization but also optimizes the quality of artificial sand, providing higher-quality raw materials for the construction industry.

After the coarse aggregate with a size of 5 to 20 mm is washed twice with mud in the pre-screening and screening workshop, the mud content of the raw material approaches zero. Then, after being washed and dewatered by the spiral classifier in the sand making machine workshop and the screening workshop, the mud content of the artificial sand can fully meet the quality requirements specified in the standard.
