摘要:
A mixing and kneading machine (1) for continual compounding comprises a screw shaft (3) rotating in a casing (2) and simultaneously moving axially translationally. To sustainably enhance the efficiency of the machine as regards its material thruput per unit of time the screw shaft (3) comprises at least four groups of radial screw vanes (4a, 4b, 4c, 4d) evenly distributed circumferentially, each group consisting of a plurality of screw vanes in axial sequence. The outer diameter (Da) of the screw shaft ranges from 400 to 800 millimeters. The rotary speed of the screw shaft (3) ranges from 30 to 80 rpm. A mixing and kneading machine (1) engineered as such is particularly suitable for compounding an anodic mass in the production of electrodes—anodes—for the aluminum industry.
摘要:
The mixing and kneading machine (1) for compounding bulk-flowable, plastic and/or pasty masses comprises a working space (9) enclosed by a casing (2), and a working member (3) moving rotatingly and translationally in the casing (2). The working member (3) comprises a plurality of kneader vanes (4). Secured to the casing (2) are kneader pins (6) which protrude into the working space (9). To optimize processing, the main surfaces of the kneader vanes (4) and/or of the kneader pins (6) are configured at least in part as main surfaces (23a-23f).

摘要:
A mixing and kneading machine (1) for continual compounding comprises a screw shaft (3) rotating in a casing 2 and simultaneously moving axially translationally. To sustainably enhance the efficiency of the machine as regards its material thruput per unit of time a screw shaft is proposed having the following geometric ratios: Da/Di=1.5 to 2.0, i.e. the ratio of screw shaft outer diameter Da to screw shaft inner diameter Di is 1.5 to 2.0, Da/H=4 to 6, i.e. the ratio of screw shaft outer diameter Da to stroke H is between 4 and 6, T/H=1.3 to 2.5, i.e. the ratio of pitch T to stroke H is between 1.3 and 2.5. The mixing and kneading machine (1) provided with such a screw shaft (3) is operated preferably at a rotational speed exceeding 500 rpm, particularly exceeding 800 rpm.
