Yunnan Kunming Ceramic Powder Low-Velocity Conveying System

A leading ceramic tile manufacturer in Kunming, Yunnan, faced significant challenges in its production line. The company required a reliable method to transport fine ceramic powder from the storage silo to the mixing station without damaging the material or creating excessive dust. Traditional high-velocity pneumatic conveying systems caused particle attrition, equipment wear, and frequent blockages, leading to production downtime and maintenance costs.

Client Challenges

The ceramic powder, with a particle size ranging from 10 to 100 microns, is highly abrasive and prone to breakage under high impact. The existing system generated static electricity, causing powder buildup and inconsistent flow. The client also needed to reduce energy consumption and meet stricter environmental regulations on dust emissions. Manual cleaning and unplanned stoppages reduced overall equipment effectiveness by nearly 15%.

Solution from Headpowder

Headpowder designed and installed a custom low-velocity dense-phase conveying system specifically for the ceramic powder application. The system uses gentle air pressure to move the material at speeds below 5 m/s, minimizing particle degradation and equipment abrasion. A specially designed feeder ensures consistent material flow, while the pipeline layout incorporates wear-resistant bends and smooth interior surfaces to reduce friction. The integrated dust collection and filtration unit maintains a clean working environment. The system also features a programmable logic controller (PLC) that automatically adjusts air-to-material ratios for optimal performance.

Key Outcomes

After commissioning, the client achieved a 40% reduction in material waste due to breakage. Maintenance intervals extended from monthly to quarterly, and energy consumption dropped by 25% compared to the previous high-velocity system. Dust levels in the production area decreased significantly, meeting local environmental standards. The system has been operating reliably for over 18 months with no unplanned downtime.
