The Jaw Crushers can be used in mining, metallurgical industry, construction, road and railway building, conversancy, chemistry, etc. For the primary, secondary and tertiary crushing of ores and rocks with the compressing strength of 147～245Mpa, to crush materials of different sizes to uniform small grains.

A double toggle machine will usually have a higher crushing force for a given power input & will exhibit more even jaw wear. Tonnage tends to be lower due to slower speed and smaller stroke. They also take up more space.

Single toggle crushers are cheaper as they contain less parts and usually crush faster due to higher speed & stroke. Jaw wear is usually concentrated over the bottom 1-2 feet of the fixed jaw.

For very hard, competent rock & long mine life, you are better off with a double toggle machine. Otherwise, a single toggle machine will normally be fine.
