Dry-method classification pulverizing process for ceramic body powder
The invention discloses a dry-method classification pulverizing process for ceramic green body powder. The dry-method classification pulverizing process comprises the following steps: A, preparing green body raw materials; b, vertically grinding the first type of raw materials to obtain pre-ground powder, and removing iron from the pre-ground powder to obtain a first pretreated material; c, taking the raw materials with the moisture content of less than or equal to 15% and the particle size of less than or equal to 3mm in the green body raw materials as second-class raw materials; d, crushing the third type of raw materials to obtain a second pretreated material; adding water into the fourth type of raw materials, performing wet ball milling to obtain slurry, and sieving and squeezing the slurry to obtain a mud cake; and F, performing vertical milling to obtain fine powder, and performing slag removal, iron removal, humidification and granulation on the fine powder to obtain ceramic body powder. According to the dry-method classification pulverizing process provided by the scheme, the green body raw materials are firstly classified and correspondingly pretreated, and then the pretreated green body raw materials are uniformly pulverized and granulated, so that the selection range of the green body raw materials is expanded on the premise of energy conservation, and the material selection difficulty and the production cost of the ceramic green body can be effectively reduced; the diversity and the flexibility of a blank formula are improved.
本发明公开了陶瓷坯体粉料的干法分类制粉工艺，包括以下步骤：A、准备坯体原料；B、将第一类原料立磨得到预磨粉，再将预磨粉除铁后得到第一预处理料；C、将坯体原料中水分含量≤15％、粒径≤3mm的原料作为第二类原料；D、将第三类原料破碎后得到第二预处理料；将第四类原料加水湿法球磨得到浆料，再将浆料过筛和压榨后得到泥饼；F、立磨得到细粉，再将细粉除渣、除铁和加湿造粒得到陶瓷坯体粉料。本方案提出的干法分类制粉工艺，将坯体原料先进行分类并作相应的预处理，再将预处理后的坯体原料统一进行制粉造粒，有利于兼顾节能的前提下，扩大坯体原料的选用范围，能有效降低陶瓷坯体的选材难度及生产成本，增加坯体配方的多样性和灵活性。
