Problems solved by technology

The disadvantages of this wet production process are: ①The production cycle is long, and it usually takes five days for a process; ②The output is low, and the monthly output of 100 employees is about 120 tons; The wet material after alkali treatment is dried, which consumes a lot of power; ④The yield rate is low, and it takes three tons of wool to produce one ton of products. Waste; ⑤, pollute the environment, need to discharge the water containing acid, alkali, and fine material suspended matter during production; ⑥, the variety is single and the quality is poor, only one kind of natural particle size product can be produced, and it cannot be produced according to the customer's requirements ⑦. The quality of the product is unstable, and the production is carried out based on the experience of the operator. Due to the difference in experience of each operator, the products produced will also be different, resulting in fluctuations in product quality. Guarantee the stability of product quality; ⑧, labor intensity is high, in each process in the production process, the transfer of intermediate materials is basically completed by heavy, strong, and large quantities of manual labor; ⑨, the entire The production process is carried out in a discontinuous state, and the mechanical continuity of production cannot be achieved; ⑩, the production cost is high. Due to the above-mentioned various reasons, the final result of high production cost

Abstract

The invention discloses a dry production process of garnet micropowder. Using natural iron-aluminum garnet ore as raw material; the raw material is dried and then pulverized; after pulverization, it is classified once, at this time, tailings are collected for small particles, and large particles are returned to pulverize; The fine powder is collected; after the secondary classification, the garnet micropowder product is obtained by sieving and packaging. The fine particles collected from the tailings and the fine particles collected from the fines are packaged to obtain the by-products of the additive. The dry production process implements program control on the mechanical device; by controlling the airflow size of the jet mill and the speed of the classification wheel of the classifier, a series of multi-variety garnet powder products are produced. For the production of garnet micropowder. It has the characteristics of short production cycle, continuous program-controlled machinery, high yield and raw material utilization rate and output, high and stable product quality and variety, labor saving and energy saving, low labor intensity, and no environmental pollution.

Description

technical field [0001] The dry production process of garnet micropowder of the present invention relates to the technical field of new materials; in particular, it relates to the technical field of new materials for grinding and polishing; in particular, it relates to the technical field of dry production process of garnet micropowder. Background technique [0002] Garnet, commonly known as natural corundum, also known as natural iron-aluminum garnet ore; it is a natural ore. This natural ore called garnet can be used as a new material for grinding and polishing after being crushed into tiny particles of a certain size; this new material for grinding and polishing can be used for various lenses and optical glass. , crystal, silicon wafer, electronic products and other grinding and polishing; its use is extremely extensive. However, for the production of this new garnet powder material, the wet production process has been used for many years. Its production process is: raw ...
