Product Description

The iron sands are mainly use for weight balance of Runway construction, port crane counterweight building, seismic stability, concrete hardening, sports equipment counterweight, deoxidizer, water purifier, water cutting medial etc. 

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.

Garnet sand is a good abrasive which is used for water filtration and as a wood finisher for furniture pieces. As an abrasive, garnet sand can be divided into two categories: blasting grade and water jet grade. Garnet sand is crushed into finer grains and used for sand blasting. The larger grains after being crushed are used for faster work while smaller grains can be used for finer finishes. Garnet sand is brittle and can fracture easily - which is the reason why different types of sand are produced.

Garnet sand is also known as water jet cutting sand. It is made from calcium-aluminium silicate and is normally used as a replacement for silica sand in sand blasting operations. There are various types of sandblasting media including mineral abrasives like aluminium oxide and coal slag. Garnet sand is the most popular sandblasting type, but since these types create a significant amount of dust, they are banned in many countries like Germany and Portugal to use as a blasting grit.
