This granulator product line in a compact and sound-insulated design is ideally suitable for installation in production lines for the immediate size reduction of production rejects such as preforms, bottles, injection moulding waste etc. The C product line is constructed in such a way that it can be cleaned easily and within a very short period of time in case of change of product and colour. Available in 6 sizes from 7.5 up to 110 kW.

Control intelligently and productivity increase! "TRANSPARENCY prevents wrong decisions and creates confidence" New capability characteristics of OPDWIN (optimal process representation under Windows) OPDWIN WLAN: OPDWIN WLAN (WLAN - Wireless local AREA network) makes it possible to convey plant information and production data over a OPDWIN PDA (PDA - personnel digitally Assistant) directly the plant driver to the "wrist". For this give it different plant concepts: Application type: - machines for mixing - Big-Bag plants - extrusion plants and everywhere, where production data are to be stored. Increase in value of OPDWIN WLAN: ·A local control room is not necessary any longer ·The plant operator is more flexible in his work areas ·Less plant stop by direct information ·Increase of the productivity OPDWIN lite: OPDWIN lite is the small brother of OPDWIN. OPDWIN lite be based on the structures of OPDWIN and is thus at any

Herbold Meckesheim has developed a granulator system for the recycling of vials with residual liquid. The waste from the process is collected in containers and fed into the granulator using a lifting and tilting device. Water is added to the granulating process in order to use the friction for dissolving the residual liquid from the surface of the material. The dirty water is spun off and material is dried. The illustration shown has been designed for a pharmaceutical company. Stainless steel is used where product makes contact. Systems can be provided with capacities from 100 to 5000 Kg/h. Special systems can be supplied for PET bottles, HDPE cans, used PP battery casings and many other applications. A test vehicle is available for testing of your material.

d99 = 63 micron is now feasible with HERBOLD knife pulverisers of the SMF series For the fine-grinding of cellulose HERBOLD can offer a special series of pulverisers with a high cutting rate. These are knife pulverisers with a high number of revolutions, equipped with rotating and bed knives. The feeding is made by gravity (cellulose sheets) or with a roller feeding device (bales), the end fineness is determined by the size of the screen holes. With intensive research work HERBOLD succeeded in sophisticating the machines so that fineness degrees of d99 = 63 micron can be reached. In the recent past this was only possible with complicated multistep procedures. The high cutting rate between rotor and stator knives and the optimal cooling system of the machine are the main advantages of the HERBOLD pulveriser design. Not only is the air stream of the suction unit used as a cooling device but also the body of the pulveriser is tempered with the help of a water cooling device. Cellulose with such a degree of fineness can lead to a dust explosion. Therefore

HERBOLD the specialist in complete recycling systems Safe recycling of film edge trims at a rate of 1200 meters/minute realized in China successfully for the first time. HERBOLD MECKESHEIM recently supplied a system for recycling film edge trims, which operates smoothly at a rate of 1200 meters/minute. The edge trims are drawn in-line, size-reduced, stored in a silo and recycled. HERBOLD simultaneously uses a blower for the discharge of the size-reduced film as well as for the suction of the edge trims. The system operates completely under pressure. Contrary to the injector evacuation with a screen basket - this is a clean and dustfree operation. For this application HERBOLD granulators with their double cross cutting geometry is used, this has a positive effect on the flow ability, bulk density, and temperature of the granulated material. The material is stored in a HERBOLD, special silo, with a bottom discharge device eliminating any risk of bridging. The material

The pulverizers type PU are modular: according to their application they are available with different rotors: grinding discs with grooved and conical grinding tools; wing beaters with replaceable ridges mounted on the periphery; pinned discs for models without screen, also counter-rotating, or blast rotors with a high self-ventilation can be supplied. Our product range has been increased at both ends. For low capacities from 10 to 150 kg/h a brand-new machine with a rotor diameter of 180 mm, the so-called PU 180, is now available. For extremely high capacities , we are now able to supply large-scale plants with a capacity up to 3000 kg/h and a rotor diameter of 1250 mm. All soft and semirigid materials can be pulverised with these machines. We will also be able to supply tailor-made machine solutions with a high ventilation, or plants with a cooling device for materials that are extremely sensitive to temperatures. Materials that are extremely difficult to pulverise

SKOV A/S now launch a new, complete series of capacitive proximity sensors. The DOL 25 series is based on a new microcomputer technology which ensures reliable detection operations in any environment. The DOL 25 series covers all requirements concerning housing and electrical and functional qualities, making it possible to meet virtually any requirement for detection. The capacitive proximity sensors excel in being 100 % temperature-stable and extremely immune to high frequency irradiation. This has been accomplished by means of an advanced circuit design and a new microcomputer platform, which forms the basis of all DOL 25 sensors. In fact, the DOL 25 series has its own integrated ”missile defence” against any attack from the outside. The flexible set-up allows the sensors to be combined in many ways to make up a wide range of variants, allowing you to get the exact function required. Among the many functionalities you find Active Temperature Compensation,
