2. GYRATORY CRUSHERS

Manufacturers redesigned their gyratories to reduce the feed opening, decrease the closed-side setting, and in- crease the gyrations per minute. Examples of this crusher are the Allis-Chalmers Newhouse and Superior McCully Fine Reduction crushers. The Kennedy Van Saun Type "S', and the Traylor Type TF and TY.

  1. Normally the size reduction by crushing is of limited importance besides the top size of the product going to grinding.
  2. This means that the number of crushing stages can be reduced depending on the feed size accepted by primary grinding stage.

Gyratory Crusher

Similar to jaw crushers, the mechanism of size reduction in gyratory crushers is primarily by the compressive action of two pieces of steel against the rock. As the distance between the two plates decreases continuous size reduction takes place.

Gyratory and Cone Crusher

Similar to jaw crushers, the mechanism of size reduction in gyratory crushers is primarily by the compressive action of two pieces of steel against the rock. As the distance between the two plates decreases continuous size reduction takes place.

SIZE REDUCTION BY CRUSHING METHODS

The gyratory crushers are robust crushers with m odern features. They are designed to giv e optimal capacity in primary crushing, increasing the total c apacity in the mining crushing process.

Gyratory Crusher (Gyratory Crushers Explained)

Gyratory crushers typically crush to reduce the size of aggregate to a maximum of about one-tenth of its original size. Gyratory crushers are always installed vertically orientated. A gyratory …

Understanding the Reduction Ratio in Crushers

What Is A Reduction Ratio Of Crusher? The reduction ratio in crushing is the ratio of the feed size to the product size during a crushing operation. It usually varies, but the reduction ratio depends on the chamber and nut adjustments.

Basics of gyratory crushers

Gyratory crushers, like jaw crushers, reduce size primarily through the compressive action of two pieces of steel against the rock. Continuous size reduction occurs as the …

AMIT 135: Lesson 5 Crushing – Mining Mill Operator Training

Gyratory crushers are operated in open circuit. The feed is limited to 1 to 1.5 meters in size. Thus, based on reduction ratio, the rock size is reduced to 10 to 15 cm. Typical reduction ratios are: Primary crusher: 3:1 to 10:1; Secondary crusher: 6:1 to 8:1; Tertiary crusher: 10:1

Crusher Reduction Ratio

As an example, suppose that it is required to make a reduction of 7:1 in two stages of crushers, one a standard gyratory and the other a fine-reduction crusher.

TECHNICAL NOTES 5 CRUSHERS

Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1. The primary operating variable available on a crusher is the set and on jaw and gyratory the open-side set (OSS) is specified. This reflects the fact that considerable portions of the processed material fall through the crusher at OSS and this ...
