The HV 70 plastcompactor is the most powerful of the series from Herbold Meckesheim. It processes the feedstock in continuous operation between a rotating and a fixed compactor disk, which are equipped with screwed-on and easily exchangeable kneading bars. Through the center of the stator disc, a stepless adjustable feeding screw continuously transports granulated material from the buffer silo into the working zone in a controlled manner. Since the rapidly warmed up material leaves the compactor zone within fractions of a second, the thermal impact on the plastic is very low. The process is regulated by two degrees of freedom – both by the speed of the screw and by the distance between the disks.
HV plastcompactors can be used to agglomerate a wide variety of materials into products of high bulk density: thermoplastics such as fibers, fine particles, small tapes, foams, stretch or thin films, powders or shavings, as well as plastics that are difficult to convey, stock or mix. Compactors are also often installed downstream of washing lines. With a subsequent agglomeration – in conjunction with a secondary granulator and a classifier – residual humidity of less than one percent can be achieved, allowing direct further processing in an injection molding machine or a standard extruder.
As part of the latest enhancements, the disk geometry of the HV 70 plastcompactor has been significantly redesigned. In combination with improved automatization of the plastcompactor and a more compact design, manual intervention during operation is required much less frequently, which offers customers a new level of operational reliability. On the other hand, the silo and feeding device have been further developed in such a way that even more complex materials with the lowest bulk densities and the most difficult flow characteristics can be handled safely.

The SML 60/100 SB 2 from Herbold Meckesheim is a granulator suitable for wet operation with horizontal forced feeding by means of screw conveyors, which allows space-saving installations and easy feeding of the material. Another advantage is the high throughput capacity thanks to a one-meter wide inlet from the hopper and 50-centimeter strong feeding screws that transport the material to be ground to the rotor. Seven rotor knives and now also an optional third stator knife allow up to 21 cuts per revolve. The SB mill can process up to two tons of polyolefins per hour or well over one ton of film. SB mills are also often used for grinding PET bottles and in washing plants for plastics recycling.
In addition to the high throughput capacity, the granulators of the series are characterized by uniform load absorption and low energy consumption. During further development, the focus was again on safety aspects and ease of maintenance: The feeding device together with the hopper can be hydraulically swung away in one piece to open the housing. The case cover with the stator knives in turn opens in the opposite direction, and the knives with the pressure bar are equipped with a lifting device for safe handling.
The discharge trough is also easily accessible. The rubber rings of the machine’s ground plate feet effectively absorb vibrations, which is reflected in low noise emissions. In any case, a sensor monitors the vibrations of the machine. And as familiar from the granulators from Herbold Meckesheim: All wear parts of the rotor of the SML 60/100 SB 2 are easily replaceable.

The T 2016 PA from Herbold Meckesheim is a mechanical dryer that has proven itself for a wide range of materials, from films and regrind to mixed and rigid plastics. Washed flakes, for example, are dried and also freed from residual impurities. The T 2016 PA is also suitable as an intensive washer – in this case, it uses a large volume of water to separate contaminants from the fraction such as paper pulp from former labels.
The machine consists of a hot-dip galvanized housing in which a high-speed agitator rotates, a polygon shaped screen basket made of stainless steel, double outboard bearings, and a pneumatic cleaning system with rinsing device for the screen surface. For heavily contaminated feedstock or feedstock with a high paper content, a cleaning scraper is used on the exterior surface of the screen drum.
Due to its novel design, the T 2016 PA achieves up to 50 percent higher drying performance, mainly due to an optimized shape and position of the replaceable and wear-resistant paddles. The screens have also been redesigned by Herbold Meckesheim with a multi-part circumference as well as a multi-part length. The hingeable housing cover, which can be opened on both sides, provides excellent access to the inside of the machine – forklifts or cranes are not required to lift off. Particularly abrasive material can be countered with wear-resistant armor. And for poorly flowing feed material, a forced feeding system via screw bunker is available.
