What are the quality requirements of quartz sand dryer for materials?

The operation of quartz sand dryer is relatively simple. Generally, you only need to set the relevant parameters. After starting the equipment, the drying process can be automatically carried out, which reduces the burden on operators. Quartz sand dryer can monitor and adjust the temperature, humidity and other parameters in the drying process in real time to ensure that the drying effect of quartz sand is stable and reliable. What are the quality requirements of quartz sand dryer for quartz sand?

(1) Particle size. The particle size of quartz sand should be uniform, and there should not be too much fine powder and large particles. Generally, the particle size of quartz sand should meet certain standards, such as 30/50, 20/40 and 40/70 of the US API specifications.

(2) Moisture content. The moisture content of quartz sand will affect the drying effect and generally needs to be controlled within 3%.

(3) Impurities. There should be no other impurities in quartz sand, such as soil, iron, manganese, etc. These substances will reduce the purity of quartz sand and affect the drying effect and output.

(4) Hardness. The hardness of quartz sand is also an important indicator. Too low hardness will aggravate the wear of quartz sand, thereby reducing the service life of the equipment.
