Bulkmatic Vibrating Sieves are primarily used to prevent foreign objects from being transferred into a process when unloading raw products in paper, plastic or hessian bags. The unit can either be used under an automatic bag slitting machine or fitted with a hatch to load bags into the unit directly. Outlet flange sizes can be modified to suit customer requirements.
The screen is bolted into the screening ring that is isolated from the support frame and inlet and outlet chute by means of Rosta tensioners and flexible sleeves. The vibrating motor is mounted to the screening ring and creates a rotary motion in the horizontal plane to assist in the screening process. Materials of manufacture are mild or stainless steel. An inspection hatch allows access to the screen for cleaning purposes. An 80NB de-dusting spigot is provided for on the top cover and should be connected to a de-dusting facility.
On the manual bag loading unit the lid is replaced with a loading chute and as an optional extra with an integrated reverse jet pulse filter to eliminate dust emissions during the loading of material.
Sieve aperture sizes are selected according to customer requirements.
