What factors affect the production efficiency of the dry sand making process in a sand and gravel aggregate production line?

The main factors affecting the production efficiency of the dry sand making process in a sand and gravel aggregate production line are as follows:

1) Raw material conditions.

In rock processing, compressive strength is key to distinguishing between soft and hard rocks, which directly affects process design and equipment selection. For moisture content, the raw material needs to be below 2% to be suitable for the dry sand making process, ensuring sand making efficiency and quality. Therefore, when choosing a sand making solution, the rock characteristics and raw material moisture content must be considered comprehensively to ensure the applicability of the process and equipment.

2) Process design.

In-depth research into the process is fundamental to designing a reasonable process. The dry process is particularly demanding on feed conditions, usually requiring smaller particle sizes and low moisture content. A particle size range of 0-15mm is ideal; if the particle size reaches 0-50mm, it will increase the processing volume, reduce output, and exacerbate equipment wear. Therefore, precise control of raw material conditions is crucial.

3) Technical indicators.

Quality indicators such as fineness modulus, powder content, and MB value must meet national or industry standards.

4) Equipment layout.

The layout is divided into tower type (tower station or tower building type) and flat type.

5) Equipment selection.

When selecting a powder separator, the characteristics of the raw materials and product requirements must be considered. Among screening equipment, circular vibrating screens are suitable for coarse screening, linear vibrating screens are suitable for fine screening, and elliptical screens combine the advantages of both. The "rock-on-metal" mode of the sand making machine is suitable for hard rocks and offers high efficiency; the "rock-on-rock" mode is suitable for soft rocks and has less wear. Key equipment performance parameters such as processing capacity and wear resistance must be considered comprehensively to ensure a smooth and efficient process.

6) Core technology.

Optimize the sand making process by considering powder removal technology, wear-resistant technology, gradation adjustment technology, intelligent control technology, and environmental protection technology.
