PRATTELN, SWITZERLAND (Oct. 4, 1:40 p.m. EDT) — Buss AG will introduce a high-performance kneader, the MX series for making cable compounds and special masterbatch production, at K 2007 in Dusseldorf, Germany, being held Oct. 24-31.
The MX offers several advantages over the company's MKS kneader, Buss said. Throughput is 2½ times more, without any increase in size. The kneader runs quality cable compound, even with very high filler content up to 68 percent by weight, with improved mechanical strength and better flame resistance. The MX also uses 15 percent less energy.
The improvements are mainly because of a new four-flight screw and a redesigned kneading chamber with greater volume. As with all Buss kneaders, the screw oscillates axially each time it rotates, a combined motion that mixes the material intensively, but gently.
Other improvements mean the mass temperature rise, as a function of screw speed, is significantly lower then earlier models — allowing higher screw speeds without exceeding the maximum admissible temperature for cable compounds.
Buss also developed a better drive, using a compact combination of four water-cooled induction motors actuating the screw shaft, through epicyclic and linear gearing.
Pratteln-based Buss became independent last year, after a management group bought the business from Coperion Group.
