摘要： A pair of compression rollers 38a and 38b parallel with each other are provided and powder grains are supplied to a powder grain introduction/compression part 50 formed between the rollers 38a and 38b and, thereby, compression moldings of the powder grains are formed. A powder grain press/feed means 20 is provided in a front stage of the rollers 38a and 38b. The press/feed means 20 has a deaerating barrel 24 and previously presses the powder grains supplied between the rollers 38a and 38b. In side surfaces of the rollers 38a and 38b, side seals 37 are arranged with clearances 72 maintained from the rollers 38a and 38b. During pressing the powder moldings, the powder grains enter into the clearances so that closer layers are formed between the side surfaces of the compression rollers 38a and 38b and the side seals 37, thereby sealing the powder grain introduction/compression part 50. In a rear stage of the rollers 38a and 38b, a shearing device 75 is provided and shears the compression moldings formed by the rollers 38a and 38b. Torque of the shearing device 75 is detected by a torque sensor, and the compression rollers 38a and 38b and the powder grain transport means 17 are controlled in accordance with the detected torque.
摘要翻译：设置一对彼此平行的压缩辊38a和38b，并且将粉末颗粒供给到形成在辊38a和38b之间的粉末颗粒引入/压缩部分50，从而形成粉末颗粒的压缩模制品。在辊38a和38b的前段设置有粉粒挤压/进给装置20。压榨/进料装置20具有脱气筒24并预先挤压供应在辊38a和38b之间的粉末颗粒。在辊38a和38b的侧表面中，侧密封件37布置有从辊38a和38b保持的间隙72。在挤压粉末成型体期间，粉粒进入间隙，使得在压缩辊38a和38b的侧表面与侧密封件37之间形成更近的层，从而密封粉粒引入/压缩部50.在后部辊38a和38b的阶段，设置有剪切装置75，并且剪切由辊38a和38b形成的压缩模制品。通过转矩传感器检测剪切装置75的扭矩，根据检测的转矩来控制压缩辊38a，38b和粉粒传送装置17。
