Powerful magnetic separator to explain the production form and advantages of tailings sand
Tailings sand belongs to the category of artificial sand. It mainly refers to the pulling of tailings produced by metal ore and non-metal ore in the process of mining and processing main ore products, which are less than 5mm after processing.
Tailings sand is mainly divided into two categories, one is the existing tailings sand, mainly the metal ore left in the process of purification, most of which are very fine, fineness modulus. _8 or so, can be used as fine aggregate for building mortar or production of building materials; another type of tailings sand is a product of sieved material of low-grade minerals, low-grade ore, surrounding rock and other waste stones that have been mechanically crushed and sieved. For medium coarse sand, the fineness modulus is between 2.6 and 3.6, and the grading and grading is stable. The grading and sieving can be carried out during production, and stored separately. According to the actual needs, the tailings sand compound with different grading and grading is selected.
The tailings of the tailings are mostly triangular or square, with rough surface and sharp edges. Compared with natural sand, tailings sand and cement and other rubber; the combination of suspected materials is good, and the compactness is high, which contributes to the improvement of strength.
The establishment of a professional production plant for the production of tailings sand contributes to the stability of tailings sand quality, especially the grading of the granules, which will change the status quo that China has not paid much attention to the quality of sand and gravel for a long time.
