Abstract
Apparatus for feeding particulate material to a roll mill, such as a roll refiner mill, or flaking mill has rollers (1, 2) pressed against each other with the help of a pressure exerting device, and a feeding compartment disposed above the nip (3) for the supply of the material to be ground. The feeding compartment (5) has a supply opening (14), succeeded by a device (11) for supplying mixed material to the rollers (1 and 2). This device is composed of a swivel spout (11) driven backward and forward, substantially lengthwise along the nip (3), by a pivot drive (13).
Claims28
Apparatus for feeding particulate material to a roll mill comprising:
- at least one pair of rollers pressed toward each other to form a nip;
- wall means forming a feeding compartment having a top portion and a bottom portion located above said pair of rollers;
- transfer means for transferring particulate material from said bottom portion toward said rollers;
- and
- supply means for supplying said particulate material into said compartment;
- and
- wherein said supply means includes:
- a supply opening at said top portion;
- mixed particle supply means which comprises swingable tube means movably supported within said compartment and extending in a substantially vertical direction so as to have a top end and a bottom end;
- pivotal support means on said tube means defining a pivot axis for allowing a swinging motion in a plane parallel to said nip, and
- swivel drive means to impart swinging motion to said tube means.
