Embodiment 1

[0020] A kind of quartz powder that the present invention proposes is used for pottery making, comprises the following steps:

[0021] S1. Pass the quartz sandstone through the impact crusher for the first coarse crushing, without screening after the coarse crushing, move the quartz sandstone to the jaw crusher for the second fine crushing, and adjust the output of the jaw crusher while finely crushing The size of the feed port is used to control the discharge particle size to obtain quartz sand with uniform particle shape, and then the second crushed quartz sand is finely crushed by the cone crusher for the third time, so that the crushed quartz sand can be crushed through the cone crusher. sieve to obtain quartz particles;

[0022] S2. Pour the quartz particles into a ball mill for primary ball milling. In the ball mill, add alumina balls with a diameter of 30 mm to carry out ball milling on the quartz sand, and then add alumina balls with a diameter of 10 mm for ball millin...

Abstract

The invention discloses quartz powder used for manufacturing ceramic. According to the invention, quartz sandstone is subjected to coarse crushing for the first time through an impact crusher; coarsely-crushed and unscreened quartz sandstone is transferred to a jaw crusher for fine crushing for the second time; during fine crushing, the size of the discharge outlet of the jaw crusher is adjusted to control the particle size of a discharged material, so quartz sands with uniform particle shape are obtained; the quartz sands obtained by crushing for two times are subjected to fine crushing for the third time through a cone crusher; the crushed quartz sands are screened through a sieve of the cone crusher, so quartz particles are obtained; impurities in the quartz powder obtained by crushingand grinding can be effectively subjected to magnetic separation for iron removal; the quartz powder with high purity and applicable to manufacturing of the ceramic is prepared after acid pickling, water washing and drying; and the quartz powder prepared by using the method provided by the invention has the advantages of high purity, fine particles and uniform particle dispersion.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a quartz powder used for ceramic production. Background technique [0002] Quartz is one of the main rock-forming minerals. It generally refers to low-temperature quartz (α-quartz), which is the most widely distributed mineral in the quartz family. Quartz in a broad sense also includes high-temperature quartz (β-quartz) and coesite. The main components are It is SiO2, colorless and transparent, often containing a small amount of impurities, and becomes a translucent or opaque crystal with a hard texture. Quartz is a mineral resource with very stable physical and chemical properties. The crystal belongs to the oxide of the trigonal crystal system. Minerals, quartz blocks, also known as silica, are mainly raw materials for the production of quartz sand (also known as silica sand), and are also raw materials for quartz refractory materials and firing ferrosilicon. Quartz is a miner...
