2. more crushing and less grinding to reduce the feed size into mill. the larger feed size, the more work that the ball mill needs to do on the ore. to achieve the specified grinding fineness, the workload of ball mill will be increased inevitably, and then, the energy consumption and power consumption will be increased accordingly.
2. more crushing and less grinding, reducing the particle size. the larger the grinding size, the more work the mill needs to do to the ore. to achieve the required grinding fineness, the workload of the ball mill will inevitably increase, and the energy and power consumption will increase. to reduce the feed size of grinding ore, it is.
A ball mill,ype of grinder, isylindrical device used in grinding or mixing materials like ores, chemicals, ceramic raw materials and paints. ball mills rotate aroundorizontal axis, partially filled with the material to be ground plus the grinding medium.
Also the grinding efficiency of ball mill will reduce. if the steel balls are too small, even the collision probability is relatively high, but the energy of single steel ball is very small, which cannot efficiently grind the ore particles, also leading to the reduction of grinding efficiency.
Ball grinding mills are classified according to the discharge methods and can be divided into overflow ball mill and grate ball mill. unlike the grate ball mill, the overflow type ball mill hasimple structure, and the discharge method is based.

Iron ore pallets plants. horizontal tube ball mill autogenous or autogenic mills are socalled due to the selfgrinding of the oreotating drum throws larger rocks of ore inascading motion which causes impact breakage of larger rocks and compressive grinding of finer particles. rourkela dist sundargarh, odisha 769015.
It hasreater impact at the drop point, the ore is mainly crushed by the impact, and the grinding efficiency is higher. 3. if the rotation speed of the ball mill exceedsertain limit the rotation speed is very high, the steel ball rotates with the barrel without falling, and is inentrifugal operation state.
It will control the grind in two ways. it affects retention time and helps distribute the ore throughthe mill so each piece of rock will come in contact with the surface of the rods. to maintainroper balance between these two is critical. what water does is kind of provideode of transportation for the ore. how water impacts grinding.

Recognize important considerations in ball mill selection. reading amp lecture. in ball mills, steel balls or hard pebbles to break particle based on impact and attrition.otating mill charged with media and ore is lifted against the inside perimeter. some of the media falls and impacts the ore particles at the bottom of the mill.
Small wet ore grinding ball mill gold mining machine extraction equipment working principle the transmission device drives the cylinder to rotate. materials and water are fed from the feeding end of the cylinder. ores are ground into fine particles by the grinding of steel rods, as well as the impact amp grinding of ores themselves.
The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 510 cm in diameter but gradually wear out. grinding is always carried out under wet conditions, with about 70 solid mixture in water. this procedure maximizes ore production and minimizes power consumption.
The charging of the ball mill milling media hasirect impact on grinding efficiencyf it is too much, the grinding media will be overlapped with each other, thus the crushing capacity of each steel ball cannot be fully utilized and the kinetic energy consumption will be increased.
