Title:
DISINTEGRATING AND GRAIN-REGULATING DEVICE FOR GRANULES
Document Type and Number:
WIPO Patent Application WO/2000/021674
Kind Code:
A1
Abstract:
A disintegrating and grain-regulating device for granules that, though working as such, is capable of controlling the grain size without using any screen whatsoever such as used in the prior art, eliminating all drawbacks, due to the use of screens, including one of kneading a material being processed or disintegrating grains of proper grain size into a large amount of fine powder to degrade the yield, and capable of regulating grains within a range of proper grain size. Disposed within a casing (1, 2) are a rotary body (6) and an opposed surface opposed to the rotary body (6) with a predetermined spacing therebetween to define a clearance region (9), the latter being defined in a grain size regulating region that allows passage of grains congruous with the predetermined clearance setting but does not allow passage of incongruous grains. The incongruous grains not allowed to pass through the clearance region (9) are brought into contact with the opposed surface at the inlet to or the surface area of the clearance region (9) in conjunction with the rotation of the rotary body (6), whereby they are disintegrated so that they can pass through the clearance region (9) and then discharge through a discharge port (4).
