Switzerland-based Buss has announced that it is exhibiting the BUSS Kneader MX 30, a four-flight laboratory, at “Wire” in Germany.
First Buss laboratory machine
This exhibition is being conducted from 26 to 30 March, 2012. The addition of this BUSS MX 30 equipment has completes its series of four flight MX compounding units. This BUSS kneader features a flanged-on discharge screw and the output rates of this device is from 5 to 25 kg per hour for batch quantities. The maximum screw speed of this MX 30 is 800 r.p.m.
The visitors at the BUSS exhibition can view the BUSS kneader along with its barrel housing in the open position, which allows for a clear observation of the four-flight co-kneader workings. These co-kneader functions include joined transverse and axial mixing action and the screw’s dual oscillating and rotational motion.
The MX 30 is specifically designed for R&D applications, together with process, optimization and formulation development. It is the first laboratory kneader, featuring flour-flight technology, and can be used for componding of shear-sensitive and heat-sensitive polymers compounding and in for generating highly filled compounds.
The cable compound industry includes silane-crosslinkable cable compounds, peroxide-crosslinking polyethylene (XLPE) for cable insulation, halogen-free, flame-retardant (HFFR) cable compounds and semiconductive polyolefin compounds for power cables.
HFFR compounds are utilized in the compounding method. The melting temperature of the compound must be under 180° C. The maximum permissible temperature of the XLPE cable compounds during the compounding method is lower by 125° C, because high temperature may cause crosslinking reactions and decomposition of peroxide. Silane-crosslinkable compounds is a liquid silane that is directly injected to the polmer melt through a special injector and is used for low-tension cable insulation. Semiconductive polyolefin compounds has conductive carbon black of up to 40% w/w. The BUSS kneader is a fully equipped small-scale compounding product line, which can be utilized for producing small quantities to be tested by customers or for small-batch production of a wide range of cable compounds.
