The invention discloses a preparation method of low-cost high-whiteness calcined talc in the field of ceramic raw materials. The preparation method comprises the following steps: step a, preparing materials: 50-80 parts of talc leftover materials, 0-20 parts of magnesian tailings and 0-40 parts of silica; b, crushing: crushing the raw materials in the step a to 15-25mm by adopting a jaw crusher; c, grinding: grinding the crushed raw materials by adopting a Raymond mill until the particle size is 200-350 meshes; d, rolling: rolling the ground raw materials into standard bricks with the length being 240 mm, the width being 115 mm and the height being 60 mm through a hydraulic brick making machine; and e, drying: placing the rolled bricks on a kiln car and feeding into a drying kiln at the temperature of 150-300 DEG C to be dried. The calcined talc is prepared by taking talc leftover bits and pieces as main raw materials and adopting a calcining method, so that the problem of reasonable treatment of the leftover bits and pieces is solved, and the product has the advantages of high whiteness, low flow rate, water permeation prevention, reduction of the calcining temperature of a ceramic body and the like.
本发明公开了陶瓷原材料领域的一种低成本高白度煅烧滑石的制备方法，包括以下步骤：步骤a：备料：滑石边角料50‑80份、镁石尾矿0‑20份、硅石0‑40份；步骤b：破碎：采用颚式破碎机对步骤a中的原料进行破碎，破碎至15‑25mm；步骤c：磨粉：采用雷蒙磨机对破碎后的原料进行粉磨，粉磨至200‑350目；步骤d：轧制：磨粉后的原料，通过液压式制砖机轧制成长240mm、宽115mm、高60mm的标准砖块；步骤e：烘干：将轧制后的砖块放在窑车上，送入温度为150‑300℃的烘干窑进行烘干。本发明以滑石边角余料为主要原料，采用煅烧的方法制备煅烧滑石，解决了这些剩料的合理化处理，本产品具有高白度、低流速、防透水、降低陶瓷坯体煅烧温度等优势。
