PDF Effect of Slurry Density on Load Dynamic . Effect of Slurry Density on Load Dynamic and Milling Performances in an Iron Ore Ball Mill - On-line Estimation of In-mill Slurry Density. Comminution Conference 2012 Cape Town 69. Get Price
Density, if you recall is the ratio of ore to water and is measured as a percent of solids in the water. It will control the grind in two ways. It affects retention time and helps distribute the ore through-the mill so each piece of rock will come in contact with the surface of the rods. To maintain a proper balance between these two is critical. What water does is kind of provide a mode of ...
It has been recognized that the grindability of an ore in a ball mill is a function of both feed and mill parameters Work index, W i Largest particle size and size distribution Density of solids and slurry Mill diameter Rotational speed Rowland and Kjos 1980 defined the largest ball size needed based on these parameters

by a ball mill in series. Crusher product -9 mm is fed to the rod mill, and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped, without any further water addition, to the first ball mill. The ball mill discharges to a sump where water is added before the slurry is pumped to the first cyclone Cylcone 1. See ...
The test is simple - after a day of ball milling let you slurry to rest unmoved for a while - if it sediments fast, say on the scale of an hour or faster, then you definitely need a dispesant too.

Mar 02, 2014 3.1. Industrial Ball Mill The ball mill utilized in the sampling survey has an inside diameter of 7.3 m and length of 9.6 m and is run in open circuit. Under normal operating conditions, the mill ball loading is 30 of total mill volume, mill rotational speed is 75 of critical speed, slurry solids concentration is 75, solids feed rate is 330 tph.
The Time that the ore spends in the grinding mill is called, RETENTION TIME. This is a very important variable, the longer the retention time, the more the ore comes in contact with the rods, the better and finer the grind becomes. To understand this important control it must be remembered that any volume that is added to a circuit must leave the circuit at exactly the same rate. All the ...
Breakage rates of particles in a ball mill change with instantaneous particle size distribution in the mill. Slurry density and the presence of a grinding aid also affect breakage rates substantially. The effect of these variables, which constitute the mill environment, on breakage rates has been quantified with a unique estimation method known as the G-H method.

The pulp weight in the mill is obtained by subtracting the mill weight during the test from the empty mill weight, including the ball charge, at the start of the test. The pulp volume of the pulp in the mill is then calculated using the mill discharge density before dilution obtained during the sampling.
IV. BALL MILLS Ball mills are one of the more common mills and use a closed cylindrical container that is rotated horizontally on its axis so that the media cascades. A typical ball mill has an LD ratio of 1.51. Ball mills are filled with spheres or other shapes made of steel or ceramics or with pebbles made of flint or of an ore being ground.

In this blog you can read there are multiple reasons for measuring density in the grinding circuit. In most sites a ball mill is used for grinding and a hydro cyclone for classification. The slurry needs to be continuously monitored and controlled. Density meters efficiently help operators to monitor and control the grinding circuit, optimize it and prevent process failures.
The slurry density pulp percentage of solids and the size of the grinding media are often used for the optimization of an operating ball mill. In many cases a change of ball size is made at the slurry density used with the original ball size. But is the optimum slurry density changing with grinding media size
This study investigated the influence of the attainable region technique to ball milling as applied in reactor technology. Flow rate, ball filling, mill speed, ball size and mill density were varied. When each was varied, the rest of the parameters were kept constant in-order to determine the influence of each parameter on the process of milling.

Effect of Slurry Density on Load Dynamic and Milling Performances in an Iron Ore In ball milling the transmission of grinding energy from the steel balls to the particles in the slurry is closely linked to the way the media and the slurry are mixed.
Dec 01, 1989 The effect of slurry density on the dynamics and grinding behavior of a batch ball mill was studied using quartz as a test material. It was found that slurry density determined the distribution of solid charge in the mill, with migration of particles from the tumbling zone to the mill periphery as solid concentration was progressively increased. This effect caused a change in the circulation path of moving balls, as reflected by the variation in mill
