Materials Handling: Larger Sizes of Economical Loaders
Wittmann Battenfeld adds larger sizes of Feedmax basic economical vacuum loaders/receivers.
At its 10th anniversary celebration in Austria in June, Wittmann Battenfeld (U.S. office in Torrington, Conn.) presented new, larger models extending its Feedmax basic series of lower-priced central vacuum loaders/receivers. Supplementing the previous models of 3 and 6 liter capacity, the new additions are 15 and 25 L, suitable for higher throughputs of 110 and 220 lb/hr, respectively. These units have a gravity discharge flap with a magnetic contact, whereas the Feedmax plus line has a pneumatic-valve discharge.
These units have a new modular design with quick release. The central part of the chamber is connected to the pedestal by a clamping ring. All parts of the loaders that contact the material are of stainless steel. Flow of pellets into the loader can be optimized by simply twisting the top of the unit. Loading time can be set simply with a potentiometer. Several loaders can be connected and operated jointly by one controller as a small central conveying system.
When it comes to vacuum conveying systems for plastics processing, custom powder handling solutions are not always required. Pre-engineered, turnkey solutions can be a perfect option for powders and bulk solids in a wide range of industries.
Processors today face bewildering choices of at least five basic types of dryers, whose capabilities are subject to conflicting claims from equipment suppliers. For the buyer, the most basic questions are: How much drying is needed for the job and which dryer types are up to the task?
