Extrusion International 1-2022

47 Extrusion International 1/2022 PLUS-S, PLUS-M and PLUS-L cover a wide range of throughputs. The ProRate PLUS feeders are capable of handling feed rates from 3.3 up to 4800 dm 3 /h [0.12 up to 400 ft 3 /h], depending on the material. Theo- retically a feeding system with six ProRate PLUS-L feeders can feed up to 28.8 m3/h [1017 ft 3 /h] on a foot- print of only 7 m 2 [75 ft 2 ]. ProRate feeders are highly stan- dardized and include a variety of design features to optimize per- formance and ease of use. Simple access for cleaning and mainte- nance, even within a cluster, is pro- vided thanks to a patent-pending rail system called “ProClean Rail”. ProClean Rail makes it possible to retract the base unit toward the rear of the feeder and rotate it for access to the feeding section and screw element. This allows for maintenance and cleaning of the feeding unit while keeping the feeder in position. In addition, the bellows and screw use the lat- est magnet technology for simple but robust mounting. The magnet connections allow these parts to be released without tools while at the same time providing the required holding force for optimal and safe operation. Thanks to the high level of standardization of the feeders, the number of spare parts required for emergency stock is minimal. Many parts are identical for all three models and can be used as exchange parts for all devices. ProRate PLUS feeders are suitable for use in hazardous locations rated NEC Class II, Div. 2, Group F & G and ATEX 3D/3D (outside/inside). Accurate weight measurement and reliable control modules for ef fi cient operation All ProRate PLUS feeders are equipped with P-SFT load cells, fea- turing reliable Smart Force Trans- ducer weighing technology. They operate under compression and provide accurate, stable and reli- able digital weight measurement under a broad range of operating conditions. The load cells supply a direct digital weighing signal and the onboard microcontroller en- sures excellent repeatability and stability. P-SFT load cells have a high tolerance to vibration and electrical noise. They feature built-in over and underload protection. Each feeder comes equipped with its own pre-wired ProRate PLUS PCM control module. The PCM is mounted to the feeder stand, with adjustable height positioning. Each PCM is pre-tested in Coperion K- Tron’s manufacturing facility prior to shipping. There are two mod- els of PCM to choose from: a basic motor control unit (PCM-MD) or an advanced version with integrated user interface and line control func- tionality (PCM-KD). Within a group of up to eight feeders, one feeder must be equipped with the PCM-KD while the PCM-MD is suf fi cient for the others. The PCM-KD comes with all the software the ProRate PLUS feeder will need for continuous applica- tions and supports all three feeder models. Connection between weigh feeders, operator interface and smart I/O is via an industrial net- work. All motor setup, diagnostics and operator interface functions are integrated into the PCM-KD user in- terface. The PCM-KD is equipped with a host communication port (Ethernet IP or Pro fi net). A variety of service offerings to keep processes running smoothly Coperion K-Tron’s dedication to customer satisfaction has also led to the creation of a unique new portfolio of service offerings for the launch of this product line. A variety of Start-up and Service Packages are available for ProRate PLUS feeders to ensure each customer can get ex- actly the level of service they need. Coperion K-Tron also offers quick and easy remote services for Pro- Rate PLUS. From an online portal to 24-hour phone support and even remote start-up assistance, trained service technicians are available to keep systems running around the globe. In all, the new ProRate PLUS feeder line offers a simple, robust and reli- able solution for feeding a variety of free- fl owing bulk materials in plas- tics processing applications. Coperion K-Tron (Schweiz) GmbH Lenzhardweg 43/4, CH-5702 Niederlenz, Switzerland www.coperion.com ProRate PLUS feeders can be installed as individual units or easily arranged in cluster of up to six feeders around a process inlet, depending on the recipe formulation
