Dry Preparation Process and Equipment for Ceramic Powder: A Comprehensive Guide

Introduction

The dry preparation process for ceramic powder is a critical step in the manufacturing of high-quality ceramic products. This method involves the grinding, classification, and purification of raw materials without the use of liquids, resulting in a fine, uniform powder suitable for shaping and firing. The efficiency and precision of this process directly impact the final product’s properties, such as strength, density, and surface finish. In this guide, we will explore the key stages of dry preparation, the equipment involved, and how advanced machinery can optimize production.

Key Stages in Dry Preparation

The dry preparation process typically includes several stages: crushing, grinding, classification, and collection. Each stage requires specialized equipment to ensure the desired particle size and purity are achieved.

Crushing

Crushing is the initial stage where large raw materials are reduced to smaller particles. Equipment like hammer mills are commonly used for this purpose. For example, our Hammer Mill (0-3mm) is designed to handle inputs up to 40mm and produce outputs as fine as 0-3mm. Its high-capacity performance and durable design make it ideal for preliminary size reduction in ceramic powder production.

Grinding

Grinding is the core stage where particles are further reduced to the desired fineness. This requires precision equipment capable of handling various material hardnesses and achieving consistent results. Our SCM Ultrafine Mill is particularly well-suited for ceramic applications. It can process materials with an input size of ≤20mm and produce powders with a fineness range of 325-2500 mesh (D97≤5μm). With capacities from 0.5 to 25 tons per hour depending on the model, it offers high efficiency and energy savings, consuming 30% less power compared to traditional jet mills. Its vertical turbine classifier ensures precise particle size distribution without coarse powder contamination.

Classification

Classification separates particles based on size, ensuring only the desired fractions proceed to the next stage. Equipment like air classifiers or integrated grading systems in mills are used. Our MTW Series Trapezium Mill includes an advanced grading mechanism that allows for output fineness between 30-325 mesh (up to 0.038mm). Its curved air duct design minimizes energy loss and improves transmission efficiency, making it a reliable choice for ceramic powder classification.

Collection

Collection involves gathering the fine powder after grinding and classification. Pulse dust collectors and cyclone systems are commonly employed to ensure high efficiency and environmental compliance. Our equipment, such as the SCM Ultrafine Mill, features a pulse dust collection system that exceeds international standards, with dust removal efficiency over 99.9% and noise levels below 75dB.
