Diamond reserves and production of South Africa are in the front rank of the world. Large-scale development and utilization of diamonds result in production of a large number of diamond wastes. Resource utilization of diamond waste can turn waste into tre
Gold ore whose types of deposits are diverse and complex is the mineral assemblage of gold. With features of chalcophile affinity and high melting point, the gold ore includes conglomerate type, porphyry type, quartz vein type and volcanic rock type, etc.
Gypsum powder plant is a kind of micronized line which turns natural dihydrate gypsum ore (raw gypsum) or industrial by-product gypsum (desulphurization gypsum, phosphogypsum, etc.) into construction gypsum (calcined gypsum) through crushing, grinding, he
Basalt is the best material for repairing roads, railways and airfield runways. It has the advantages of abrasion resistance, less water consumption, poor conductivity, strong compressive strength, low crushing value, strong corrosion resistance and asp
Gravity separation is the main beneficiation method of chrome ore, and the equipment is jigger, shaking table, spiral classifier, centrifugal concentrator and spiral chute, etc. Sometimes it will also use weak magnetic separation or strong magnetic separa
Magnetic separation makes use of magnetic differences between minerals to separate material, which occupies a very important position in iron ore separation field. Magnetic separating plant has the advantages of energy saving, high efficiency and high

General Mole Balance Equation Assumptions 1 Steady state therefore 2 Well mixed therefore r A is the same throughout the reactor Rearranging the generation In terms of conversion Reactor Sizing Given –r A as a function of conversion –r A fX one can size any type of reactor The volume of a CSTR can be represented as the
Such advances make it possibte to consider mixing in a much more detailed manner The ultimate aim of agitation in the tank is the promotion of certain transport processes andor reactions Detailed spatial distributions of various quantities ie local effects need to be known for reliable design and scaleup of agitated tanks
Jul 15 2003 · This 1to10 agitation scale is based on the impeller pumping capacity divided by the tank crosssectional area resulting in a bulk fluid velocity This velocity in feetminute ftmin then is divided by 6 to obtain the scale of agitation

design the impact of decisions made at the process design step on the mechanical design requirements must be understood The second step in the design sequence is the mechanical design of the mixer components The fundamental approach is straightforward design for power torque and speed then shaft loads and finally mixer dynamics
These agitators can be mounted in tanks with rounded or conical bottoms They operate at a lowmoderate mixing speed with a peripheral velocity of 2 to 7 ms Blades are axial flow agitators ideal for solidinliquid solutions and suspensions because they prevent solid particles from depositing on the bottom of the tank
peller design Using the impeller shear rate the local viscosity can be calculated from Equation 6 or 8 The local viscosity can then be used to determine the Reynolds number Re from which the impeller’s power number Po can be derived Po is a function of Re The absorbed power can then be calculated using P P oρND3 5 10
Mechanical design does not end with the shaft since strength and practical issues remain for the impeller Another part of mixer design is the tank in which the mixer is used since tank dimensions influence mixer features especially shaft length Conversely a mixer requires tank features such as baffles support strength and other tank
