Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuitfor example your ball mill is in closed circuit with a set of cyclonesthe grinding mill receives crushed ore feedthe pulp densities around your cyclone are sampled and known over an 8hour shift allowing to calculate corresponding to circulating load
Jan 01 2013 at each iteration the circulating load cl is calculated using the following equation l l b 5 2 the circulating load calculation shown in equation 2 differs from the one proposed by tsakalakis 2000 by combining the unit operations efficiencies in a single parameter pi
Where the sag millball mill circuit is the bottleneck in the processing plant the pebble circuit can be a significant factor in limiting overall plant capacity the pebble circuit recirculating load can be very significant depending on the ore characteristics and sag mill operating dynamics
Figure 2 closed circuit ball mill flowsheet classification before milling secondary ball mills 1 1 c1 c2 q2 2 e2 kq 3 q1 1 1 c2 c1 2 e1 the relative capacity of closed ball mill circuits at varying circulating load is compared to a base case with 250 circulating load and 50 classification efficiency typical for classification with

Lets first clearly define "circulating load ratio" as the ratio of the amount of solids going through the ball mill divided by the amount of solids going through the circuit as it turns out a valid "massbalance" formula can be derived from the following two questions
Sep 07 2011 re vrm and ball mill circulating load mainly in usa the term circulating load is more often used than the circulation factorcirculating load is percentage of coarse return in relation to fines it can be calculated by coarse return tph x 100 mill output tphnormal range of cirulating load in a conventional close circuit ball mill is around 100200
Jan 01 2013 a problem for solving mass balances in mineral processing plants is the calculation of circulating load in closed circuits a family of possible methods to the resolution of this calculation is the iterative methods consisting of a finite loop where each iteration the initial solution is refined in order to move closer to the exact solution
Find some actual lead balls to do the milling implement some sort of screen in the mouth to prevent the balls from falling out when emptying the mill create a mount so the mill can be stationed on a table while spinning i would love to see you build a ball mill and make changes to my design show me how innovative you can be

Fig1 manhole of batch ball mill batch ball mill the balls as will as the feed are charged through an opening in the lateral wall and discharge is through an opening just opposite to the charging manhole in case of wet grinding the discharge opening is fitted with a valve to regulate the flow of slurry fig2 description of continues ball mill 1
Increase in mill speed and ball filling leads to a remarkable increase in the amount of the power preliminary results show that there is a definite trend between the power and the slurry filling u mill power draw is maximum at slurry concentration 6070 and slurry filling 084
The industrial ball mills are one of the most common types of crushing and milling equipment their simple design ensures longterm and reliable operation generally any faults and malfunctions of a ball mill are caused by wear of individual parts of the machine during operation

Sep 07 2011 re vrm and ball mill circulating load mainly in usa the term circulating load is more often used than the circulation factorcirculating load is percentage of coarse return in relation to fines it can be calculated by coarse return tph x 100 mill output tphnormal range of cirulating load in a conventional close circuit ball mill is around 100200
Jul 30 2014 abstract load parameters inside the ball mill is one of the key factors that affect grinding production ratio and production quantity of the grinding process directly the ball mill produces soundly mechanical vibration and acoustical signals many methods have been applied to measure them in this paper a new frequency spectral feature of hilbert vibration decomposition hvd based soft
The milling process definitions cutting speedv c indicates the surface speed at which the cutting edge machines the workpiece effective or true cutting speed v e indicates the surface speed at the effective diameter dc apthis value is necessary for determining the true cutting data at the actual depth of cut a pthis is a particularly important value when using round insert cutters
Second we have to find out the volume of water in the feed and we know it contains 40 percent solid therefore the water volume in the feed is 212120406 which is equal to 31816 m3 similarly you can find out the volume of water in underflow 35 percent is recycled so that will be equal to 035 into 31816 so that makes 11136 m3
