Cerabeads

Macawber Denseveyor Pneumatic Conveying System

IN BRIEF

A customer purchased three 8/8-5 Macawber Denseveyors® to convey abrasive cerabeads (synthetic sand). Systems 1 and 2 convey cerabeads from a 150T silo to a proclaimer and reclaimer, one at approximately 125-linear feet and the other at 150-linear feet, at a rate of 20Tons per hour. These two Denseveyors® were replacements for existing systems. The customer installed a new sand reclaimer, therefore creating the need for another pneumatic conveying system. System 3 conveys cerabeads from a proclaimer approximately 155-linear feet to two existing 53Ton bins at a rate of 10Tons per hour. Due to the abrasive nature of cerabeads, these systems also contain basalt-lined elbows. Each system is equipped with 8” Macawber Dome Valves® and 15” HMI touchscreens.
