Ceramic Random Packing

Ceramic random packing, also named as ceramic column packing, packed tower packing, is usually in shape of saddle and ring. Ceramic surface of ceramic random packing can form extremely thin film, which can promote the mixing of liquid and vapor. Thus, the resistance to vapor is decreased and flux is increased a lot when vapor-liquid flows through the packing bed.

What We Offer

Alfa Chemistry can offer ceramic random packings in a wide range of specifications and sizes which have high chemical resistance, high temperature resistance, good mechanical properties, high abrasion resistance and low water absorption. The types of ceramic random packing what we can offer are as follows:

Features and Application

Compared with metal and plastic random packing, ceramic random packing is highly suitable for the conditions of higher temperature and lower temperature, and has higher resistance to chemical solvents, including organic acid, inorganic acid and solutions except the hydrofluoric acid. In addition to the high chemical resistance and temperature resistance, ceramic random packing is with good mechanical properties, high abrasion resistance and low water absorption.

Ceramic random packing can be used in the drying columns, absorbing columns, cooling towers, scrubbing towers and actifier columns in chemical industry, metallurgy industry, coal gas industry, oxygen producing industry, etc.

Production Process

Figure 2 presents a general process flow diagram for ceramic random packing manufacturing. The basic steps include raw material procurement, beneficiation, extrusion moulding, drying, firing, final processing, and packaging.

  • Raw material and beneficiation

The raw material mainly refers to kaolin, feldspar and clay.

The basic beneficiation processes mainly include comminution, purification, sizing, classification, calcining, and liquid dispersion. The purpose of comminution is to liberate impurities, break up aggregates, modify particle morphology and size distribution, facilitate mixing and forming. Other processes also aim to improve the purity of the material and are advantageous to follow-up processing.

  • Extrusion molding and drying

Ceramic extrusion molding has become a standard process in the ceramics industry in the last 20 years. After forming, ceramic random packings must be dried. Drying must be carefully controlled to strike a balance between minimizing drying time and avoiding differential shrinkage, warping, and distortion.

  • Firing

Firing is the process by which ceramic random packings are thermally consolidated into a dense, cohesive body comprised of fine, uniform grains. This process also is referred to as sintering or densification. Parameters that affect firing include firing temperature, time, pressure, and atmosphere.

As a leading manufacturer of ceramic random packings, we have the expertise in the operational requirements and compliance and standards of many different industries across the globe, we can help you choose the best product for your requirements.
