Now it is possible, in one single size-reduction step, to both shred and obtain small granule sizes with the HB Series granulator. The design of this machine combines a feed hopper and a hydraulic ram with a granulator. The special…
Hapman The Helix Hi/Lo flexible screw conveyor (photo) is designed for handling sluggish or non-free-flowing materials without the need for separate in-hopper agitation. The system encourages discharge of sluggish solids with an optional mass-flow hopper with a steep conical shape,…
Amandus Kahl This firm has developed a process for ambient grinding of waste tires that is said to be more economical than traditional ambient or cold grinding processes. Tires are first cut into 50–100-mm chips, which are then conveyed to…
Agglomeration is the process of converting fine powder particles into larger particles by the introduction of external forces. Agglomeration is often desirable because the process yields a product that has a higher bulk density, contains less dust, and has improved…
An improved understanding of air classifier systems and their application can help in selecting the right device Mechanical centrifugal air classifiers are used extensively to process aggregates, ceramics, chemicals, foods, minerals, metals, plastics, flyash and other materials. They are normally…
Question: Should we convert from manual dumping of sacks to discharging from bulk bags? Answer: Dry, bulk chemicals have long been purchased in 50-lb (23-kg) paper and plastic sacks for several reasons. In volumes smaller than rail and truckloads,…
These days, there seem to be more reasons than ever to change feedstocks throughout the chemical process industries (CPI). Whether environmental, or more directly based on financial and market drivers, big benefits usually require big changes. This is especially true…
Feeder combines speed with accuracy Hapman The PosiPortion feeder (photo) offers a 2-in-1 feed screw option that dramatically improves batch accuracy without compromising speed. A two-speed delivery scheme, consisting of a fast turning “bulk-mode” and a slower “dribble-mode”, are used…
Storage of bulk materials in hoppers, bins and silos is ubiquitous in the chemical process industries (CPI), and so are the challenges that go along with it. Flow stoppage (bridging or arching), variability in mixture composition (de-mixing or segregation), erratic…
