Application

 

It is used as the pre-treatment of industrial water softer and desalted treatment and groundwater deiron demanganese of medium and small town, village water supply, remote mountainous and industrial enterprises.
1.MnO2>35%, the product is commonly used for the iron ion and manganese ion removing of the drinking water, underground water and industrial water.
2.MnO2≤30%, it is applied to iron ion removing from the water including the lower 20mg/l of iron ion content.

The general process for preparing low iron sand is as follows:
1. Raw material preparation: Select high-purity silica or quartz sand as the raw material, crush, wash, and sieve it to remove impurities and coarse particles.
2. Roasting: Place the processed raw materials into an electric furnace or high-temperature furnace for high-temperature roasting treatment to improve the crystalline state and physical and chemical properties of the sand. The calcination temperature is generally between 1200 ºC and 1400 ºC, and the time is about 2-3 hours.
3. Grinding: Grind the roasted sand to achieve uniform particle size for subsequent processing.
4. Iron removal: Use a magnetic separator or high gradient magnetic separator to remove iron ions from the sand, in order to achieve low iron requirements.
5. Grinding: Use a fine grinder or ultrafine grinder to grind the sand after iron removal, with a particle size generally below 5 microns, in order to be applied in high-tech fields.
6. Packaging: The finely ground low iron sand is packaged and encapsulated according to customer requirements to ensure product quality and stability.
It should be noted that environmental protection and safety issues need to be taken into account during the preparation of low iron sand, especially in the dust treatment of roasting and crushing processes. At the same time, strict quality control and testing of raw materials and finished products are also necessary to ensure that the products meet customer needs and standards.
