Zirconia-Toughened Alumina (ZTA) wear-resistant ceramics are composed of alumina and zirconia, combining the high hardness of alumina with the high toughness of zirconia. Through microcrystalline strengthening and dispersion toughening mechanisms, the material significantly improves impact resistance while maintaining excellent wear performance. ZTA ceramics achieve a Rockwell hardness of HRA 90 or above and a wear volume of less than 0.01 cm³, maintaining stable abrasion resistance under demanding conditions such as high speed and high pressure. The mining, mineral processing and bulk materials handling industries face severe abrasive wear and impact loads from ore particles on processing equipment. Critical components including chutes, hoppers, transfer points, cyclones and pipe elbows demand wear lining materials with both high abrasion resistance and impact resistance. ZTA ceramic liners have demonstrated service life 2.8 to 4 times longer than conventional alumina ceramic liners u...

Plastic tower packing is a tower internal filling component manufactured from heat-resistant and chemically corrosion-resistant materials including polyethylene (PE), polypropylene (PP), reinforced polypropylene (RPP), polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), and polyvinylidene fluoride (PVDF). This type of packing features high void ratio, low pressure drop, low mass-transfer unit height, high flooding point, and sufficient gas-liquid contact. Compared with metal and ceramic packings, plastic packings are lighter in weight, more impact-resistant, more cost-effective, and less prone to breakage. The long-term operating temperature ranges from 60°C to 150°C depending on the material selected. Three typical plastic packing types include Pall rings, Cascade Mini Rings, and Intalox saddle rings. Pall rings are modified from Raschig rings with two rows of rectangular windows and inward-bent tongues, increasing gas-liquid flow passages and offering high capacity, low ...

The cyclone separator is a critical piece of equipment that utilizes centrifugal force for solid-liquid separation and classification, and is widely used in mining, metallurgy, coal, petrochemical, and environmental protection industries. During operation, the high-speed rotating solid-liquid two-phase flow generates continuous and severe impact and abrasion on the internal walls, particularly at the feed inlet, cone section, and apex discharge port. This wear not only causes shell thinning and structural failure but also reduces separation accuracy and classification efficiency due to increased internal surface roughness, ultimately significantly shortening equipment service life and driving up maintenance costs. Consequently, equipping cyclones with high-performance wear-resistant liners is a core technical measure to ensure their long-term, stable operation. Wear-resistant ceramic materials have become the ideal choice for cyclone liners due to their high hardness, excellent wear re...
