Hapman Compact Sieve Animation

How to read the demonstration

The animation documents the named machine and its operating sequence. Read it as a visual explanation of equipment boundaries and interfaces, not as a universal design rule or a performance guarantee: it does not establish unreported throughput, accuracy, certification, material suitability or project results.

Engineering interpretation

Placed beneath a bulk bag discharge, a compact sieve acts as an inline quality-control boundary before powder enters the next process step. The useful engineering view is therefore wider than the screen itself.

Bag agitation, liner behavior and the discharge connection determine how consistently material reaches the deck; the screen aperture and vibration then determine what can pass; and the downstream hopper must accept the screened flow without backing material up into the sieve.

Selection should start with the contaminant or agglomerate size that must be rejected, not with a nominal capacity alone.

Cohesive powders may blind an aperture, fragile particles may be damaged by prolonged residence, and dusty products may require a sealed connection and controlled extraction. Access for inspection, screen changes and cleaning matters most where allergens or multiple recipes are handled.

A site review should also confirm how rejects are contained, how the screen is verified after maintenance and whether the supporting structure isolates vibration from load cells or neighboring equipment.

Questions to carry into specification

Confirm the material data, required operating envelope, upstream and downstream interfaces, cleaning method, containment target, utilities and control philosophy for the real installation. Ask the supplier which details in the animation represent the offered configuration and which are illustrative. Any safety, hygiene or explosion-protection requirement must be assessed against the current equipment documentation and the rules applicable at the installation site.
