Problems solved by technology

[0004] In many stone processing enterprises, after cutting out marble engineering slabs according to customer needs, the discarded marble leftovers are wasted, and most of them are used as filling materials for building houses. It is very troublesome to deal with at ordinary times, and they are piled up for a long time, taking up a lot of space.

Abstract

The invention relates to a preparing method of using marble wastes to recycle heavy calcium powder. The preparing method comprises the steps of material selecting, cleaning, airing, crushing, screening through vibration, ball-milling and grading. The preparing method is simple in technology and convenient to operate, achieves recycling and reuse of the marble wastes so as to turn waste into wealth, saves investment cost and mineral resources, and is very environmentally friendly.

Description

technical field [0001] The invention relates to the field of heavy calcium powder production, in particular to a method for recycling heavy calcium powder by using marble waste. Background technique [0002] Heavy calcium, calcite powder, is the abbreviation of heavy calcium carbonate, which is ground from natural carbonate minerals such as calcite, marble, and limestone. It is a commonly used powdered inorganic filler, with high chemical purity, high inertness, not easy to chemical reaction, good thermal stability, no decomposition below 400 °C, high whiteness, low oil absorption, low refractive index, soft, dry, It does not contain crystal water, has low hardness, small wear value, non-toxic, tasteless, odorless, and good dispersibility. Ordinary heavy calcium powder, ultrafine ground calcium carbonate, wet ground ultrafine calcium carbonate, and ultrafine surface modified ground calcium carbonate can be provided as required. [0003] At present, heavy calcium has been w...
