Engineering notes and best practice

The articles here are written for people specifying or running powder handling equipment: how vacuum and pneumatic conveying differ, when dense phase is worth the extra cost, how hopper refill control affects throughput, and where dust actually escapes in a filling or packing area. They are practical rather than promotional, and each one is based on duties we have worked on.

• Conveying: dilute phase against dense phase, and how to choose between them.
• Equipment: how vacuum conveyors, rotary valves and receivers are selected and sized.
• Process: dosing, mixing and batching in powder and additive lines.
• Plant practice: dust control, housekeeping and maintenance intervals.
• Industries: what changes when the material is food, battery or chemical.
