Cone Crushers | McLanahan

A Cone Crusher is a compression type of machine that reduces material by squeezing or compressing the feed material between a moving piece of steel and a stationary piece of steel. Final sizing and reduction is determined by the closed side setting or the gap between the two crushing members at the lowest point. As the wedge or eccentric rotates to cause the compression within the chamber, the .

Crusher Size Reduction Ratio Calculation Method

Generally, every crusher machine is not the same, here are several common crusher size reduction ratio: The impact crusher size reduction ratio is 20 to 1. The vertical shaft impact crusher size reduction ratio is 4-8 to 1. The vertical roller mill size reduction ratio is 2-2.5 to 1. The hammer crusher size reduction ratio is 20 to 1.

 · Jaw Crushers The next development in the field was the invention of Jaw Crushers in 1840’s in North America. Eli Blake patented the Double toggle Blake Jaw Crusher in 1858. The Blake type Jaw crusher has fixed feed opening where as the dodge type jaw crusher has fixed discharge opening. 2/25/2015 6:58:05 AM 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


6. Dry the sample again to a constant weight on a hot plate or in an oven at a temperature of 230°F (110 ºC), then accurately weigh and record. 7. Separate the sample into individual sizes using the proper sieves. The sieves normally used are the standard 8 inch (200 mm) sieves.

Takt time, cycle time, and lead time explained

Cycle Time = Net Production Time/Number of Units made. Cycle Time example (+ Cycle Time Calculator in Excel) Let’s take the doll factory example once again, and look at the Cycle Time for Doll# 1 (Jessica). We’ll take the same Net Production Time, and assume that 45 dolls are really made during this time: Net Production Time = 550 minutes


3.9 Examples. Examples of machine rates for a power saw, a tractor, a team of oxen, and a truck are in the following tables. Although the machine rates in Tables 3.5 to 3.8 share the same general format, there is flexibility to represent costs that are specific to the machine type, particularly in the calculation …
