What is the difference between a SAG mill and ball
Principle of SAG Mill operation. SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills Small Ball Mills Canada.

Types of Crushers: What You Need to Know Machinery
Roller crusher diagram Hammer mills and impact crushers. One of the most versatile crushers available, hammer mills and impactors can be primary, secondary, and tertiary crushers. Hammer mill crushers use continuous hammer blows to shatter and disintegrate material. They are typically horizontal rotating in an enclosed cylinder casing.A survey of 40 industrial mills in Australia found that the maximum ball mill diameter in use was 5.34 metres and length 8.84 metres [1]. Autogenous mills range up to 12 metres in diameter. The length-to-diameter ratios indicated in Table 7.1 for ball mills are for normal use, but for primary grinding the ratio could vary between 1:1 and 1.8:1Tubular Ball Mills ScienceDirect
