Classifiers nonmechanical

Classifiers can be grouped into horizontal current and vertical current types, or into mechanical, nonmechanical, sedimentation, and hydrauHc or fluidized-bed types depending on the design of the equipment. The available equipment, their sizes, capacities, and their uses are given in Table 5. 

M = mechanical transport of sands to discharge N = nonmechanical gravity or pressure S = sedimentation classifier and F = fiuidized-bed classifier. 

The hydrocyclone, commonly referred to simply as cyclone, is a nonmechanical sedimentation-type classifier (2,6,10,27) (Fig. 7). It has no moving parts or power attachments directly connected to it. The hydrocyclone has become the workhorse of most mineral processing operations because of its simplicity, short residence time, compactness, and low cost of operation. It is, however, characterized by lack of sharpness of separation. Equipment... 

Classifier types fall into two basic categories (1) gravitational and (2) centrifugal classifiers. Gravitational classifiers can be subdivided into (1) sedimentation and (2) hydraulic classifiers. Furthermore each type falls into mechanical and nonmechanical types.

Micropumps can be classified into two general categories mechanical and nonmechanical micropumps (an excellent review on micropumps can be found elsewhere [1]). In a typical... 

Reactions require accurate dosage of reactants to achieve the optimum stoichiometry. An array of components for fluid manipulation have been developed over the last decade for micrototal analysis systems ( xTAS) and microreaction technology. Pumping of fluids is carried out using microfluidic components, which can be classified as either mechanical or nonmechanical. Mechanical pumps are distinguished from nonmechanical pumps by the presence of a moving physical part. 

We implicitly note that d(PV), like the other functions of state in Eq. (1.9.10a), represents the changes in the irreversibly executed infinitesimal step. The other types of work are classified as being nonmechanical.
