Feed systems fillers

Due to the variable flow characteristics of powdered fillers, and the range of addition levels often demanded (for example, from 20 to 80% by weight), it is not possible to design a unified feed system for all materials [155]. Considerations include the operational design and accuracy required from the feeders, the location of filler addition (within solid or melt zones, or a combination of both) and the need to utilise a stuffer screw. A variety of feeding options are illustrated in Fig. 32. [Pg.204]

If a plant cmshes to obtain stone of 0.6 and 7.6 cm for lime-kiln feed, coarse aggregate, or fluxstone, much undersized material is also produced. Oversized material can be reduced by recycling through the cmsher system, but the subsized stone, called spall, is wasted in a spall pile. Such spalls have potential value as by-products for use as, eg, asphalt (qv) filler. [Pg.170]

Kutrieb Corporation (Chetek, Wisconsin) operates a pyrolator process for converting tires into oil, pyrolytic filler, gas, and steel. Nu-Tech (Bensenvike, Illinois) employs the Pyro-Matic resource recovery system for tire pyrolysis, which consists of a shredding operation, storage hopper, char-coUection chambers, furnace box with a 61-cm reactor chamber, material-feed conveyor, control-feed inlet, and oil collection system. It is rated to produce 272.5 L oil and 363 kg carbon black from 907 kg of shredded tires. TecSon Corporation (Janesville, Wisconsin) has a Pyro-Mass recovery system that pyroly2es chopped tire particles into char, oil, and gas. The system can process up to 1000 kg/h and produce 1.25 MW/h (16). [Pg.15]

In the epoxy adhesive industry, fillers are generally added as a batch process rather than a continuous process. Batch systems are especially suited to short-run operation in which additives and materials are often changed. They allow for greater control of residence time, shear, and temperature, and they can accommodate a feed rate that is not free-flowing. [Pg.393]

Any fertilizer compaction/granulation system can be utilized as a regional production facility for the manufacturing of bulk-blend grade material from off-specification feeds. This capability also includes special formulations that are required by the local market such as indigenous fillers, with or without major nutrients, or carriers... [Pg.675]
