In the sand and gravel emergency, sand making machine production is gradually replacing natural sand and becoming the new supply main body of the sand and gravel industry by virtue of its stable supply and abundant raw materials. At the same time, the quality of machine-made sand is also gradually being paid attention to. With the increasing demand for machine-made sand, how to improve the quality of machine-made sand has become a topic of concern to the sand and gravel industry, but do you know what factors affect its performance?
1. Selection of parent rock
Machine-made sand is mostly used in engineering fields such as construction, road, water conservancy and hydropower, so its compressive strength, wear resistance, weathering degree, corrosion resistance, green and non-toxic and other factors need to be considered. The influence of mechanical properties The strength, mineral composition, rock structure and chemical composition of the parent rock vary, and have a significant impact on energy consumption, stone powder content and particle shape.
The cleanliness of the parent rock should be well investigated in the selection of mines in the sand field, and the mines with thin covering soil, less mud in the interlayer, high strength of the parent rock and good rock integrity should be selected, so that during mining, the mixed There will be relatively less impurities and sediment, and it will be easier to control the mud content of the machine-made sand and ensure the quality of the machine-made sand.
2. Selection of sand making equipment
As the core sand making equipment, sand making equipment is the key that directly affects the quality of machine-made sand, so the choice of sand making machine is particularly important. At present, impact sand making machines are mainly used in the market. VSI vertical impact crusher is a sand making machine with dual functions of sand making and shaping. It has the characteristics of excellent product quality, large throughput and strong adaptability.
3. Sand making process
The production of machine-made sand does not rely on only one piece of equipment, but requires a sand-making production line. While a good sand-making process meets environmental protection requirements, it can not only reduce the loss of fine sand but also ensure the quality of the finished sand. Usually, a sand-making process The configuration of the production line includes: vibrating feeder, jaw crusher, impact crusher/cone crusher, sand making machine, sand washing machine, vibrating screen, conveyor belt, etc.
To sum up, in the production of machine-made sand, it is necessary to pay attention to the characteristics of the raw materials of machine-made sand, and at the same time choose suitable sand making equipment, and comprehensively consider the production situation of the sand making production line, so as to have better production efficiency.
