Buhler TSK-Extruders are now equipped with internal cooling of the housing.

The entire BTSK extruder model range is now fitted with an internally cooled housing. Every housing can be efficiently cooled with water via cooling bores, which produces a more efficient operation and higher capacities. Furthermore, the torque per shaft has been raised to 135 Nm, which is available over the entire r.p.m. scope. The machine has a 37 kW motor.

The housing can be delivered in two versions: either in standard execution as mono block in nitrided steel, or in the two-piece execution with wear bushings. The compact piping system for the cooling of the housing is installed at the side opposite of the operator. This allows full access to the operator side for ease of operation and maintenance. In order to enable application of the machine for trial purposes the piping for the cooling system is a very flexible design for fast addaption to specific applications. The process section is heated by means of electrical heating shells, up to a maximum temperature of 450°C.

The 30 mm extruder is the first of the BTSK that is operated by means of a 15“ touch panel. Buhler is utilizing similar control systems with great success for a wide range of machines and processes. In the near future the entire BTSK extruder series will be available with touch screen operating panels.
