The Standard and NonClog Industrial Hammermills are designed to reduce the material to a nominal 3" to 5" (75mm to 25mm) output. These are primary stage crushers, commonly followed with Centerfeed Mills or other types of secondary stage crushers. The HammerMaster is also a secondary stage crusher in that the maximum feed size is 6" (150mm).

Crushers are used to reduce particle size enough so that the material can be processed into finer particles in a grinder. A typical processing line at a mine might consist of a crusher followed by a SAG mill followed by a ball mill. In this context, the SAG mill and ball mill are considered grinders rather than crushers.

Frictional wear or rubbing forces act on the particles, as well as collision energy. These forces are derived from the rotational motion of the balls and movement of particles within the mill and contact zones of colliding balls.

Since there are not that many small SAG mill operations of under 2000 TPD, and most sub2000 TPD mills are built with rod mills and/or ball mills only; the upstream crusher plant needs to have sufficient crushing power to provide a P80 to grinding of typically <″ (40 mm) and often as finely crushed as <3/8″ (9 mm).

The hammer mill is the best known and by far the most widely used crushing device employing the impact principle of breaking and grinding stone. Thus far we have described machines which do a portion of their work by impact, but the only machine described in which this action plays an important role was the sledging roll type and particularly the Edison roll crusher and in these machines ...

In many cases, the increased throughput of the SAG mill cannot be matched by the existing ball mill if a conventional pebble crusher is used. For this purpose, the HPGR offers the advantage that the HPGR's discharge contains considerable amounts of finer product at a reduced material strength/reduced Bond work index which, in turn, increases ...

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.

For a ball mill to work, critical speed must be achieved. Critical speed refers to the speed at which the enclosed balls begin to rotate along the inner walls of the ball mill. If a ball mill fails to reach critical speed, the balls will remain stationary at the bottom where they have little or no impact on the material. Ball Mills vs ...

E = K R f c (1/L 2 1/L 1) Where: E=Energy, K R =Rittinger's Constant, f c =crushing strength of the material, L 1 =initial length, and L 2 =reduced length. Kick's Law states that the energy is proportional to the size reduction ratio. The equation for Kick's Law can be written as: E = K K f c log e (L 1 /L 2)
