Embodiment 1

[0013] Example 1 whiteness requirements 92-93

[0014] Adopt 4-level homogenization steps, followed by raw material homogenization, semi-finished product homogenization, finished product wet homogenization, and finished product dry homogenization; the specific steps are as follows:

[0015] a. Homogenization of raw materials: Australian sand and Indonesian sand are selected, of which Australian sand accounts for 2 / 3 and Indonesian sand accounts for 1 / 3, both refer to the weight relationship, the particle size is 100 mesh, and the mixing is carried out in the homogenization bin by batching; It is controlled by the delivery volume of different raw materials per unit time. If this level of homogenization is not carried out, the indicators of the produced products will be different.

[0016] b. Homogenization of semi-finished products: the homogenized raw materials are put into the buffer bin through the bucket elevator, and the materials enter the continuous ball mill inlet from ...

[0022] Adopt 4-level homogenization steps, followed by raw material homogenization, semi-finished product homogenization, finished product wet homogenization, and finished product dry homogenization; the specific steps are as follows:

[0023] a. Homogenization of raw materials: Australian sand, Indonesian sand and Vietnamese sand are selected, of which Australian sand accounts for 2 / 3, Indonesian sand accounts for 1 / 6, and Vietnamese sand accounts for 1 / 6, all refer to the weight relationship, the particle size is 100 mesh, and the batching method is adopted Stirring is carried out in the homogenization bin; it is controlled by the delivery volume of different raw materials per unit time. If this level of homogenization is not carried out, the indicators of the produced products will be different.

Abstract

The invention belongs to the technical field of homogenizing of super-fine powder of zirconium silicate and particular relates to a method for homogenizing super-fine powder of zirconium silicate. The technical scheme is that four levels of homogenizing processes, namely raw material homogenizing, semi-finished product homogenizing, finished-product wet homogenizing and finished product dry homogenizing are adopted. By means of the method, the problem that indexes of zirconium silicate products are unstable is solved, requirements of customers are met, and product quality is ensured.

Description

technical field [0001] The invention belongs to the technical field of homogenizing zirconium silicate superfine powder, in particular to a method for homogenizing zirconium silicate superfine powder. Background technique [0002] In the current production of zirconium silicate ultrafine powder, there are usually whiteness, content (physical and chemical indicators), uneven particle size and instability. In order to produce high-quality products, three stable indicators are strongly required, namely whiteness. , a stable indicator of particle size and content. [0003] At present, the three indicators of the product are all unstable, and the fluctuation amount is 0.5%~1% times; the error of granularity is D 50 The value error is 1~3 microns; the whiteness error is within plus or minus 2.5 degrees. [0004] The main reason for the above problems is that the vast majority of manufacturers of zirconium silicate ultrafine powder adopt the one-step method of ball milling in sma...
