Twin-screw extruders | machinery feature


an 800-kW motor, twice that of the next largest model, the FED 72 MTS. “Most of our customers do not require high levels


of torque, and place more value on the adaptability of our extruders to a wide range of applications,” Gross says. “Nevertheless, we now have a machine for companies wanting high outputs of a limited number of compounds based on engineering thermoplastics.” Gross also points out that the screws on all FED MTS models have no kneading blocks, and instead have specially designed mixing elements that create no shear-induced temperature spikes and less degrada- tion. Feddem extruders have barrels with special heating cartridges, so the percentage of heat that comes from shear in the melt is less than on other compounding extruders. JSW is also talking about torque with its new high-end, high-output compounder, the TEXα III. “Torque is a key factor in the faultless performance of the TEXα III extruder series,” the company boasts. Applications include high-quality compounding, masterbatch production, devolatilization, rubber/elastomer process- ing and dewatering. “The benefi cial results are complex


JSW’s TEXα III high-output


extruder boasts a 36% increase in torque


mixing with highest possible throughput compounding and improved conveying capacity,” JSW says. The TEXα III also gets its higher torque – up by 36%


compared to its predecessor – from a new gearbox, and a new design of screw shaft made with improved materials. “Complex alloys developed exclusively in JSW’s own steel refi ning mills have been used to improve strength and durability,” says the company. Cited benefi ts are longer lifetime, higher output

compared to its predecessor


Excellent product quality, especially with thermally sensitive compounds


The unique kneading block free screw geometry of the FED-MTS allows thorough and consistent mixing of the product without the occurrence of shear induced temperature spikes.
