Vibration Systems & Solutions EziPack 4 vibrating feeder

In addition to the regular EziPack vibrating feeder, Vibration Systems & Solutions has released the EziPack 4, a smaller version with a 4 L hopper and reduced tray size. The tray is still in a vee shape, but, with reduced cross-section, it offers exceptionally fine adjustment of feed rate. On recent tests the unit was capable of being controlled to give a mass increment of 0.0001 g.

The unit is driven by a linear vibrator and can be operated fully manually or via an electro-pneumatic controller. The latter is connected to an electronic scale to allow two-speed, ‘rapid–fill: slow-top-up’ operation. This makes the unit suitable for highly accurate and repeatable filling of small containers for assay or sampling test work.

Other than the vibrator and air controls, all parts are stainless steel and, while the vibrator unit is aluminium, it does not require any lubrication, so there is no danger of product contamination.

Although pneumatic equipment is often considered to be intrinsically safe, the Netter NTK model vibrator can also be supplied to ATEX specifications for use in dust- or gas-hazardous atmospheres.
