Screenless granulator with small footprint

Screenless granulator with small footprint

Wittmann‘s new SJ914 C, a compact version of their SJ914 screenless granulator, requires approximately 45 per cent less floor space simply by changing the gearbox design to allow the motor to be mounted at 90 to the rotor shaft.

With a cutting chamber size of 9.4 inches by 13.6 inches (240 mm by 346 mm) and a throughput of 44 lbs/hour (20 kg/hour), the SJ914 C is designed for the granulation of bigger sprues and parts made of hard, filled plastics. The reduced footprint makes it ideal for beside-the-press operation without compromising throughput.

The SJ914 C has a low rotor speed of 32 rpm, for quiet operation with minimal fines and no longs — an advantage for beside-the-press operation. The hardened, reversible knives provide double the life and reduce maintenance costs. The staggered breaker knives are designed to cut thick cross-sectioned parts. The stainless steel feed hopper allows for easier cleaning and is available with an optional magnet to help capture ferrous metal contamination. The regrind collection bin is made of stainless steel to eliminate corrosion and improve material flow.

Environmentally friendly portable chilling

Colortronic is introducing their first “green” portable chilling line with the GP Series, which offer R410a refrigerant designed to meet new regulatory requirements taking effect in 2010.

R410a refrigerant, is chlorine-free, which complies with the Environmental Protection Agency’s newest, most stringent guidelines. The benefits to R410a include improved system efficiency as well as higher capacity rates.

An electronic modulating capacity control maintains leaving fluid temperature to within 0.1F, and electronic sensors with digital readout include leaving and entering fluid temperatures, compressor suction pressure, compressor discharge pressure, condenser inlet temperature, superheat, sub-cool, pump pressure and tank level. Monitoring the conditions of the chiller provides “adaptive control”, where the operator can adjust the operation of certain components with the chiller approaches an alarm condition in an effort to keep the chiller running with minimal to no downtime.

Optional web access to the controller will allow a Colortronic or other qualified technician to diagnose alarms and see real time data without having to go directly to the site. The controller includes alarm history and capacity profile information.
