The Ball Mill, the Pebble Mill and the SAG Mill are 3 of the most popular types of mills on the industrial market. They are primarily used for the Mining industry, but they can also be used in the Chemical & Processing industry which has it's own category page for those listings here: Ball, Pebble, SAG Mills for Chemical Use .
The primary difference between a ball mill and a SAG (Semi-Autogenous Grinding) mill lies in their operation mechanisms and the materials they use for grinding. Ball mills utilize steel rods, balls, or similar media to grind materials, whereas SAG mills use a combination of large rocks of the ore and steel balls to perform grinding.
A comparison of the grinding media is given together with the knowledge gaps that still need to be bridged to improve the quality and performance of grinding media used in ball mills.
Ball mill: When the particle size of the product is less than 0.5mm, the grinding effect of the ball mill is greater than that of a rod mill of the same specification. SAG mill: The SAG mill has a wide range of feeding particle sizes and can process larger minerals, but at the same time, its output particle size is relatively larger.

Figure 1 : Grinding Power to produce various product sizes in a Ball Mill (9mm balls) and an Isa Mill (2 mm sand) (for KCGM pyrite concentrate) Chemistry Impacts The use of inert grinding media gives a crucial advantage to stirred milling in fine flotation and leaching applications. Even if it were economic to grind to 10 microns in a steel ...
An increase of over 10% in mill throughput was achieved by removing the ball scats from a single -stage SAG mill. These scats are non- spherical ball fragments resulting from uneven wear of balls ...
Ball mill： Ball mills are the most widely used one. Rod mill： The rod mill has the highest efficiency when the feed size is <30mm and the discharge size is about …
Optimum ball charge in a SAG mill is a function of many factors. Some are discussed below. For a SAB or SABC circuit. In general, the higher the ball charge the higher the throughput (and fine feed helps as well). Of course, you need a bigger ball mill. But, high ball loads mean higher ball consumption in the circuit.
Vertical roller mills Vs ball mills has long been a raging debate in the cement industry. In spite of the fact that vertical roller mills have been around for over ten years now and have gradually become the standard as far as cement manufacturing goes, several cement manufacturers still prefer ball mills for cement production when they want to design new …

Surely its got to do with the feed size and product reduction size required? SAG mills are used predominantly with feed material with a larger max lump sizes (from primary crushing plant typically in the max lump size range 150 mm to 300mm and a psd to follow) and the ball or rod mills are for smaller feed lump sizes.
Ball Mill Introduction . There are three main stages to mineral processing in the mining industry.These are: Comminution (crushing and grinding).; Beneficiation (separation and concentration).; Smelting and refining.; Ball mills are employed in the comminution stage as grinding machines (size reduction).The purpose of grinders in the mining industry is …

Conical ball mills are suitable for both coarse and fine grinding. Planetary Ball Mills: These mills consist of a rotating sun wheel and one or more grinding jars, which rotate around their own axis in the opposite direction of the sun wheel. Planetary ball mills are ideal for nano-scale grinding and mixing. Vibratory Ball Mills: Utilizing ...
These two types of mills are filled with varying compositions of grinding media. SAG mills contain balls of up to 150mm in diameter that occupy 5%-18% of mill chamber volume. Ball mills, conversely, contain …
A comparison of the grinding media is given together with the knowledge gaps that still need to be bridged to improve the quality and performance of grinding media used in ball mills.
