Jaw crusher performance can be optimised for increased aggregate quality.
Jun 01, 2020nbsp018332The part of aggregate processing investigated in this paper is the crushing, specifically primary crushing using a jaw crusher. Coarse aggregates for unbound use are often produced using a single crushing stage in a jaw crusher, as opposed to concrete or asphalt aggregates, where at least two and often three or four crushing stages are used.
Figure 5-7. Jaw Crusher After primary crushingreduction the resulting aggregate generally is placed in a large quotsurgequot pile where the aggregate may be fed into the secondary operation whenever convenient. Care is always taken when building up and loading out surge piles, as this.
A parameter study using a jaw crusher is designed to investigate the influence of feed gradation, feed rate, crusher setting and crusher speed on the crusher operation and the quality of the produced aggregates. The study is focused on the production of all-in large-sie top sie 90mm aggregates, suitable for use in subbase and frost protection layers in a pavement structure. Aggregate quality is measured in terms of product gradation, particle shape and mechanical properties.
Feed gradation, crusher setting and crusher speed affects the specific energy consumption during crushing. Particle shape is affected by all parameters feed gradation, feed rate, crusher setting and crusher speed. Mechanical properties are least affected by the jaw crusher parameters, but sample preparation using laboratory crushing clearly affect mechanical properties.
The results from this study provide valuable knowledge for the optimisation of single-stage crushing regarding crusher operation and aggregate quality. By adapting the crushing process to the available feed material and desired product, the quality of the crushed product can be optimised along with the crusher operation.

The width of the jaw determines capacity. Jaw crusher output gradation is controlled by the closed side setting. This is the adjustable opening at the bottom of the jaw. With a 24 top sie limit and an 81 reduction ration, the closed side setting should be no smaller than 3. A well designed jaw should be 80 to 85 percent efficient.

Jaw Crusher Primary Crusher in Mining Aggregate JXSC. Jaw crusher is a universal stone crusher in the mining industry. Application jaw crusher machine widely used in the mineral processing plant, building material industry, aggregate processing plant, roads, railways, water conservancy, chemical and so.
A jaw crusher has a wider range of settingsgenerally, a maximum of two to three times the smallest setting. The tables also show that for a comparable maximum sie of feed and setting, a gyratory crusher has a much greater capacity than a jaw crusher.
