Many practitioners in the powder processing industry are plagued by recurring production issues in daily operations: frequent equipment wear shortens service life, blockages from accumulated fine powder halt production schedules, and iron contaminants mixed into finished products compromise quality. Ultra-fine processing across chemical, mineral and advanced new material sectors is beset by persistent pain points, pushing up overall production costs and dragging down product qualification rates.Qingdao Shina has recently completed loading and delivery of its QWJ series jet milling production lines and ATP series air classification production lines. Optimized in configuration, these equipment lines tackle multiple common production drawbacks at the source.

 

 

Fabricated entirely from stainless steel for main components, the complete unit avoids material contamination caused by equipment rusting, complying with stringent raw material requirements for fine powder manufacturing. High-stability alumina liners are fitted inside wear-prone milling and classification chambers; boasting exceptional abrasion resistance, this material drastically cuts chamber attrition induced by high-speed raw material impact. The core classification impeller is precision-manufactured from silicon nitride, featuring outstanding wear and impact resistance to resist deformation and abrasion during prolonged high-speed rotation and sustain consistent classification accuracy over the long term. A polyurethane protective lining is added to the inner wall of the matched dust collector to shield against erosive dust abrasion and extend the service life of the dust removal system. This three-layer anti-wear protection package curbs spare part replacement frequency and cuts downtime for maintenance.

 

 

Revised chamber geometry optimizes material flow paths to prevent fine powder adhesion and accumulation, fundamentally resolving silo blockage and enabling uninterrupted smooth material conveyance. No ferrous components come into direct contact with raw materials throughout the whole production flow, eliminating the risk of iron shavings contaminating finished powder and safeguarding product purity. Built on proven jet milling and classification technologies, the equipment balances ultra-fine fineness and production efficiency, enabling powder manufacturers to streamline workflows, control production costs and achieve quality and output upgrades. It stands as the preferred processing equipment for enterprises upgrading their powder production lines.
