A cone crusher in a secondary crushing application will typically work with a 3.5:1 to 5:1 reduction ratio. Tertiary cone crusher configurations typically work with a reduction ratio of 2.5:1 to 4:1. The reduction ratio is defined as the ratio of the feed size for which 80 per cent will pass (F80), divided by the product size for which 80 per ...

The mechanism and motion characteristics of these crushers also differ. The single toggle jaw crusher produces a downward and forward motion, which results in higher throughput. On the other hand, the double toggle jaw crusher creates a nutcracker-like action with its unique circular motion, providing more control over the final product size.

Impact Crusher Working Principle. Starting from the base working principle that compression is the forcing of two surfaces towards one another to crush the material caught between them. Impact crushing can be of two variations: gravity and dynamic. An example of gravity impact would be dropping a rock onto a steel plate …

The right crusher for every stage. The primary crushing stage generally breaks down the material into pieces of max 200 – 300 mm. The aim is to achieve the right balance between feed size (capacity) and throughput (speed).

Crusher efficiency refers to the ability of a crusher to effectively reduce the size of raw material into smaller, more manageable pieces. Benefits include increased production capacity, reduced energy consumption, and improved product quality. Common problems, such as liner wear, overloading, and material hardness, can impact crusher …

At a rotor tip speed of 45m/s, crushing is at its lowest, but we have a high capacity. At 82m/s, crushing is at its highest, but we have a lower capacity. The size of the crusher product also depends on the feed size, the throughput, the crushability of the material, and whether or not the cascade feature is used.

13.3.1.1 Primary Crusher. Primary crushers are heavy-duty rugged machines used to crush ROM ore of (−) 1.5 m size. These large-sized ores are reduced at the primary crushing stage for an output product dimension of 10–20 cm. The common primary crushers are of jaw and gyratory types.

Impact crushers can achieve higher reduction ratios than jaws and gyratory's but are limited by high rates of abrasive wear and thus are restricted to somewhat softer rocks (Duthoit 2000). In the aggregate industry, for tonnage outputs less than 1000 metric tons per hour, jaw crushers are the dominant type of primary crusher.

The paper concerns investigation of the effect of impact crusher operation on selected qualitative characteristics of mineral aggregate products. Qualitative characteristics of crushing products in terms of size reduction ratio and fine particles contents were analyzed from the point of view of operational parameters of the impact …

I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged. Both of these …

Bi-Flow® material = 23 tph. i.e. Rotor throughput x 20%. Total crusher throughput 143 tph. Varying the ratios of rotor to Bi-Flow® feed material can be extremely beneficial when attempting to "tailor" a product for the customer. However, this is best done on site during the commissioning stage. PRODUCT CURVES

The first rotor is equivalent to coarse crushing and the second rotor is equivalent to fine crushing, i.e. one impact crusher can be used as coarse crushing and medium and fine crushing equipment at the same time. The crusher has a large crushing ratio and high production capacity, but consumes more power. 1.5.3.
