SRP has earlier studied a new way of calculating the cost in crushing and screening the results was a satisfactory, SRP is now ready to go further in this study. The purpose of this study is further develop of the earlier adopted generic cost model earlier developed by Heyman and Lindström in order to calculate the cost per metric ton within the world of crushing and screening.

The jaw crusher is evidently the more economical machine in this case, and its first cost is only about half that of the gyratory crusher. If the capacity of the primary breaker is required to be 100 tons per hour or over, a gyratory crusher is likely to be more economical than the other type, since it costs no more than a jaw crusher of similar capacity and consumes less power.

Crushing and de-stemming Ripe bunches of grapes are fed into the crusher/de-stemmer. Stems are removed through a sieve system and grapes are then crushed by rollers. A 5–10% solution of sodium metabisufite is added to the grapes to inhibit growth of wild micro-organisms and prevent oxidative browning of the juice.

A Gyratory crusher can be fed from two sides and is able to handle ore that tends to slab. Its design allows a higher-speed motor with a higher reduction ratio between the motor and the crushing surface. This means a dollar saving in energy costs. A Jaw crusher on the other hand requires an Ely wheel to store energy.

Crusher manufacturers publish grid charts, particle size cumulative distribution curves, and/or product size distribution tables to help predict the gradation of the crusher product. These charts, curves, and tables give the percentages passing or retained on standard size screens for each given setting of the crusher.
