Continuously operating equipment

Non-mechanical equipment and systems will normally have an absolute fault limit that specifies the maximum recommended level for continued operation. Equipment or systems vendors will, in most cases, be able to provide this information. 

Scale-ups from small scale, often batch, laboratory investigations to commercially sized, continuously operating equipment, which in addition may... 

As compared with the product from batch mixer-agglomerators, granular products from continuously operating equipment feature wider particle size... 

In continuously operating equipment, these growth regions take place simultaneously. As mentioned previously (see Section 7.1) the critical phase of the process is the formation of nuclei. This must always take place at a sufficient rate to guarantee the transformation of the often highly adhesive feed material into a freely flowing granular mass. 

While all of the examples that were discussed so far featured continuously operating equipment, it should be pointed out, that in some industries, for example the pharmaceutical industry, fluidized bed processors are used in batch modes. Fig. 7.79 is the... 

Thermoforming equipment ranges from inexpensive single-station prototype or sample machines to massive units producing industrial components. Small manual operation machines provide for economical short-run production. High-production equipment can produce thousands of parts and requires the use of automatic, continuous-operation equipment. 

For the more demanding suspension duties, for example, continuously operated equipment with an overflow of the suspension, a uniform suspension is required. To achieve this, both the Is criterion at the bottom of the vessel and the visually uniform suspension criterion must be fulfilled.
