### Crusher Efficiency Calculations

Considering a 30-in. diameter roll crusher the maximum size particle that can be nipped with the roll crusher set at 1 in. according to this Equation is F = 0.085(15) + 1.0 = 2.28 in. <3½ in. feed. It will take larger than a 40-in. diameter roll crusher. A better solution would be to use a larger jaw crusher set at 1½ in., then a roll crusher from the Roll Crusher capacity Table above could be used. If the output of …

### Soybean Crush Reference Guide - CME Group

these numbers to data on their own production efficiency to determine the profitability of processing – this calculation is referred to as the Gross Processing Margin (GPM) or “Crush.” To Calculate the Crush or GPM [(Price of Soybean Meal ($/short ton) x .022) + Price of Soybean Oil (¢/lb) x …

### Capacities and performance characteristics of jaw crushers

between the calculated KI and F,,/G (Table I) can be repre- sented by the equation: K1 = 0.85 - (Fav/G)2.5 (1 0) Effect of throw The necessary data for studying the effect of throw on the performance of jaw crushers are given in Table 2 (Hersam, 1923). For calculating the values of K2, the value of Kg for

### Gyratory and Cone Crusher - ScienceDirect

A cone crusher of height 2.1 m, open side feed opening 30.4 cm and a closed set at 5.1 cm gyrated at 480 rpm to crush quarry limestone scalped at 20.3 cm opening screen. The crusher was expected to crush at the rate of 1000 t/h. Calculate 1. the level at which the charge has to be maintained, 2. angle of the crusher head. 5.6

### Design of a crushing system that improves the crushing ...

Jaw crushers are sized on the basis of the maximum particle size to be crushed and/or the tonnage rate to be crushed. Maximum particle size should not exceed 80% of the gape. For example, a 400- by 600-mm crusher will accept a maximum lump size of 400 by 0.8 = 320mm. In actual operations, the crusher will occasionally accept particles up to

### Primary Crusher Selection & Design

No crusher, when set at any given discharge opening, will make a product all of which will pass a screen opening of the same dimensions as the given discharge opening. In in-pit crushing, the primary function of a crusher is to provide a smaller uniform product size for each of transport by the conveying system. Minimum power consumption in part of a good design. For their coarse duty, primary ...
