PDF Determination of Particle Size Distribution-apparatus and

cle size distribution of mill products is the main subject of this paper. Turbidimetric determinations have also been applied to measurement of particle size. Kent-Jones (8) has described the ~ use of a turbidimetric method for determining the size distribution of flours. Essentially this apparatus measures the projected area

Dec 23, · Particle size, number of balls, particle density, hardness, number of media used, time of grinding, and speed of the ball mill (rpm) are factors which will affect the process of milling. Size: The smaller the media particles, the smaller the particle size of the final product.

THE OPTIMAL BALL DIAMETER IN A MILL

which can grind efficiently in a mill, c is the exponent which characterizes the ball size distribution. The condition for efficient grinding, defined by Eq. 7, will be fulfilled when the grain size distribution and the ball size distribution are the same, which means that the parameters of both distributions are equal in Eqs. 7 and 9: m c.

Particle Size Distribution Effects that Should be Considered

He concluded that the size distribution from a laboratory rod mill gave a similar-shaped size distribution to that of a closed circuit laboratory ball mill. He also demonstrated how a laboratory rod mill gave a similar shape of size distribution to a 36 inch (0.8 m) Hardinge ball mill in closed circuit with a rake classifi er treating the same ore.

Mill fresh feed particle size distribution was also determined using rod screens and laboratory screens. Weight of these samples after drying was 75 and 105 kg. Fresh feed flow rates for first and second stage sampling were 142 and 141 t/h that is almost two times of designed capacity. For mass balance of hydrocyclone streams flow rates and
