Position: A new Kason 3-in-1 batching system combines a Vibroscreen vibratory screener, a batch hopper, and an integral feeding control device that regulates the flow of material into the screener
The batch hopper system is intended for applications that require screening in batches.
The feeding controller consists of a circular control disc positioned below the flexible connector at the screener inlet, perpendicular to the flow of material.
The diameter of the disc is smaller than the inside diameter of the inlet, forming an annular gap through which material can pass.
Because the disc vibrates with the screener lid to which it is affixed, the flow of material through the gap remains uniform.
Interchangeable discs in a range of diameters are provided to achieve various feed rates.
The screening assembly is suspended on springs that allow it to vibrate freely while minimising power consumption and preventing vibration transmission to the floor.
Beneath the assembly is an imbalanced-weight, gyratory motor that creates multi-plane inertial vibration for the purpose of controlling the flow path of material on screen surfaces, and maximising the rate at which material passes through the screen.
Material is fed through the feeding control device onto the centre of the screen, causing particles larger than screen apertures to travel across the screen surface in controlled pathways, and exit through a discharge spout located at the screen periphery, while particles smaller than screen apertures pass through the screen onto a domed pan and exit through a lower discharge spout.
Vibration of the screener is isolated from the rigidly mounted surge batch hopper and support frame by means of a flexible connector.
Vibroscreen vibratory screeners available with the feeding control device range in diameter from 460 to 1016 mm and are offered with single or multiple screening decks, separating particles in one to five predetermined sizes from 50 mm to 25 microns.
The screeners are constructed of stainless steel to industrial, food, dairy and pharmaceutical standards.
The company manufactures a broad range of circular vibratory screeners, centrifugal screeners, and circular fluid bed dryers, coolers and moisturisers with a weigh batch hopper.
