Extrusion press for producing pellets, includes rotary guide device for directing spring loaded press parts into holes in die

摘要

The press comprises a die containing holes for receiving the fine material, a number of press parts for compressing the material in these holes and a guide device which can be rotated relative to the die and press parts. The guide device has a rotation axis extending parallel to the hole central axes and comprises a guide part formed by a guide cam or surface facing the press part and designed to move this part towards the hole in the die each time it makes one revolution. The end of the press part is spring-loaded so that it springs back out of the hole after compressing the material in it.
