Ball mills tend to produce a lot of attrition and abrasion but little impact. SAG mills can produce a lot of impact if operated with a high ball charge and low filling. Rod and AG mills can produce a lot of attrition and varying amounts of impact and abrasion. Arraying different mills can take advantage of the strengths of particular equipment.
I am designing foundations for FAG Mills and Ball Mills. I need guidance on use of nominal reinforcing steel. ... That's what #14 and #18 rebar are for. In principle, just design the foundation the same way as smaller one, make sure that you meet the minimum percentage rebar, and use at least one mat top bottom. Keep all the bars the same size.
Construction of Ball Mill. The ball mill consists of a hollow metal cylinder mounted on a shaft and rotating about its horizontal axis. The cylinder can be made of metal, porcelain, or rubber. Inside the cylinder balls or pebbles are placed. The balls occupy between 30 and 50% of the volume of the cylinder. The diameter of the balls depends on ...

Figure Displacement of balls in mill. where D m is the mill diameter in meters. The optimum rotational speed is usually set at 6580% of the critical speed. These data are approximate and may not be valid for metal particles that tend to agglomerate by welding. The minimal magnitude of ball size is calculated in millimeters from the equation:
generation of resonance can be suppressed by changing the design of the structure 16. ... Taking the × m ball mill foundation as the research object, the foundational length is 33 m ...

SAG mills use a combination of steel balls and rock particles as grinding media, while AG mills use only the ore itself. Both types of mills are used for grinding ore in mineral processing operations, but SAG mills are larger in size and can grind larger quantities of ore. AG mills, on the other hand, are smaller and are typically used for ...

hemisphere. It employs the world's largest SAG mill, 40 ft diameter and two 22 ft ball mills in the grinding circuit. In that project, the owners considered it necessary to assess the dynamic response of the foundations for the SAG and ball mills due to vibration problems experienced in other installations. Numerical models of the foundations
1. INTRODUCTION The foundation acts as a rigid body assumed normally in classical empirical methods for dynamic analysis, (, Barkan1962). However, the structure of a mill foundation and...

A major advance in the modeling of ball mills became possible through the development of the discrete element method. DEM provides a numerical procedure for solving Newton's second law with an appropriate contact relationship that can be applied to describe the motion of each grinding medium contained in the mill charge to predict element position, velocity and forces of interaction over time.
Dry and wet ball mills have the same basic components, but there are some structural differences: 3 Discharging part Discharging port: Dry ball mill: The ball mill needs to be equipped with an air induction device, a dust exhaust pipe and a dust collector. The structure is more complicated, and the discharge port is straight.
