Equation 2.8 is the one-dimensional form of Fourier's law of heat conduction. The proportionality constant k is called the thermal conductivity. Its units are W / m-K. Thermal conductivity is a well-tabulated property for a large number of materials. Some values for familiar materials are given in Table 1; others can be found in the references.

Equation 2 indicates that to estimate the diameter of the feed, the nip angle is required. The nip angle on its part depends on the coefficient of friction µ between the roll surface and the particle surface. The relationship between compressive force, F, coefficient of friction, μ and nip angle is given by, (4) Dividing both sides by

Gape: The distance between the fixed jaw and the tip of the swing jaw at the widest opening. Throw: Maximum distance of movement of the swing jaw. Angle of nip: The largest angle made by the two jaws that will allow the pieces of rock to be nipped and crushed. Factors influencing the energy consumed by crushers: 1) Size of feed, 2) Size of product,

pulverizer. Figure 3 illustrates the angle of nip in a jaw crusher.

These jaws can be flat surfaced or corrugated.

1 August 15, 2007 1 17. Shaft Design Objectives • Compute forces acting on shafts from gears, pulleys, and sprockets. • Find bending moments from gears, pulleys, or sprockets that are transmitting loads to or from other devices. • Determine torque in shafts from gears, pulleys, sprockets, clutches, and couplings. • Compare combined stresses to suitable allowable stresses,

nip-angle of 20" has an a value of 1.18, and an angle of 30" has an a value of 0.88, see Fig. 1. r is the realization factor. It is unity for per- fectly uniform choke feeding and usually less for actual operating conditions according to the method of feeding used and the probabilities of hang-ups involving the size of feed and crusher opening ...

s is jaw throw, m; a is the nip angle; k is a material factor, 1.5 to 2.0 (includes your epsilon param) N is RPM; This form works out volume of one motion of the jaw, multiplies by RPM then multiplies again by 60 to give volume/hour. …

Crushers: Jaw Crusher The jaw open and close 250-400 times per minute. Mechanism: Compression Eccentric drives a pitman which is connected to two toggles among which one is connected to frame another to moving jaw. The greatest motion is at the bottom of 'V' which means there is little tendency to choke. Feed size 1.8m (6ft) in diameter.
