jaw crusher production capacity Example capacity calculation of a 10″ x 20″ (250 mm x 500 mm): Pp = 2800 (2.8 SG) e = 0.2 (halfway between dolomite and sandstone) A = 250/1000 x 500/1000 Wj = 0.5 Nj = 225 = 2800 x 0.25 x 0.5 x 0.5 x 225 x (1-0.2)/60 = 525 kg/hr = 13 TPD vs 300 to 420 TPD —> I can't make this work!
The reduction ratio for crushing gives us important information about how large or coarse the feed can be for the crusher to handle and how fine or small the output or product will be. For example, a 6:1 reduction ratio means a crusher will break a 6" piece, or input, into 1" pieces on average. These ratios can determine which crushers will ...
The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m. Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate:
Designed up to one-third longer, it exerts greater pressures in the upper portion of the crushing chamber, distributes crushing action more evenly. The result is a gradual reduction of ore to the choking point, and increased capacity! Metal is concentrated at points that make for the most effective jaw design.
If your application permits to use an impact crusher over a jaw and cone crusher setup there are numerous reasons that support the use of an impact crusher. Less fuel burn: Only one machine burns fuel. For example, if you can save 8 gal / h in fuel over 1,500 hours a year at an average fuel cost of $4.50 per gallon this equates.
Reduction Ratio of Sampling Jaw Crushers Jaw Crushers typically have a crushing ratio of 6:1, though there are a number of high efficiency Jaw Crushers available that can produce smaller crushed product sizes with higher crushing ratios (possibly as high as 8:1 or 10:1), albeit at lower feed rates.

The reduction ratio of a jaw crusher is a critical parameter that determines the efficiency of the crushing process. It is defined as the ratio of the size of the feed material to the size of the product. In other words, it is the degree of reduction or size reduction achieved in the crushing process.
Jaw Crushers. Reduction ratio - 6:1. Jaw Crushers use pressure to break up very hard, flaky, and slabby rocks by passing them between a moving surface and a stationary one. …
The crushing ratio is 6-8 to 1. The impact crusher operates much in the same method as a single impeller, with counter-rotating (two) impellers which not only impel the material against the breaker bars, but also impel material high inside the chamber to be fractured on other incoming feed. Uses impact to crush material. Crushing ratio is 20 to 1.

Limitations of a jaw crusher: lack of fine material. Typically, jaw crushers produce less fine material than impact crushers. The reduction ratio of a jaw is approx. 4 to 1. Fines are necessary to meet certain gradations and increase material compaction. This is the reason why a jaw crusher is predominenatly used as a primary crusher for an ...
Product Introduction. JXSC jaw type rock crusher is usually used as a primary crusher and secondary crusher to reduce the size of medium-hard materials to smaller physical size. Jaw rock crushers are capable of working with the mobile crushing station, underground crushing because of its related small volume. Capacity: 1-1120TPH.
