Figure 20 depicts the dependence of particle strength a on particle size dp for a variety of solids (22). The differences in (r(dp) are so distinct that a similarity in strength of these materials cannot be anticipated. Whether or not laboratory measurements may be conducted with limestone and the results used to design a crusher or a grinder for quartz is a question that cannot be answered. [Pg.45]

To examine the similarity in particle strength of these materials, a standard representation of this physical property must be calculated. Figure 21 shows it in the pi space... [Pg.45]

At the bottom of the bed, the particles will be not only under the pressure of the other layers of solids but also under the hydraulic pressure of the liquid. Thus, the maximum bed height should be also be determined by using the particle strength data. The following equation could be used for the evaluation of the maximum bed height (Inglezakis, 2002) ... [Pg.537]

Fc = the maximum force that can be applied to a single particle without breaking it (particle strength). [Pg.537]

For example, for clinoptilolite (common zeolite species with particle strength of about 2 Nt) and 1.4-1.7 mm particle size, the maximum bed high is very high, near 50 m. In any case, the lower height derived from the last two equations should be used. [Pg.537]

This is a very important result. It states that both dipole amplitudes from the RRPA calculation are modified by a common factor that reflects the influences of electron correlations in the initial and final ionic states which are beyond mean-field electron-electron interactions. The A0a0 2-value is called the spectroscopic factor (or the quasi-particle strength or the pole strength or the renormalization factor) and describes the weight given to the improved 2p photoionization cross section as compared to a calculation which does not include these specific electron correlations. The remaining intensity is transferred to satellite processes... [Pg.214]

A wide variety of catalytic materials are used as slurry-phase catalysts, most being metals supported on high surface area alumina, carbon, and silica (Fig. 2, label 3). Physical properties such as density are important since these catalysts must be suspended in the reaction mix. Since rapid agitation could lead to abrasion and attrition of the catalyst particles, strength is important. [Pg.104]

Horticultural Vermiculite —Grade of vermiculite sold for horticultural applications. Such grades of vermiculite have smaller particle size resulting in improved water retention, particle strength, and wettability than coarser grades of vermiculite. [Pg.350]

Further, toxicity, volatility, and corrosiveness must be taken into account for environmental and safety reasons. Last, the particle shape and particle strength can be significant when considering the type of equipment to be specified. [Pg.330]

This is only a problem with moving or fluidized operations. Catalyst particle strength must match specific requirements. Attrition toss is usually determined by some standard test, described in Chapter 7. [Pg.135]

Characteristics relating to the resistance to destruction such as the particle strength, the probability of breakage, the mass-related work input or the specific reaction force. [Pg.97]

Fertilizers are packaged in a variety of different forms including solids, liquids (solutions and suspensions), and gas (anhydrous ammonia). The important physical properties of solid fertilizers are particle size, particle strength, caking tendency, chemical stability, and hygroscopicity. [Pg.92]
