crusher capacity vs feed size

Jaw crushers can be divided into two basic types, single and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation, along with the toggle plate, causes a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of ...

The feed size to the HPGR in some Brazilian mines is 90% passing 1 mm [3], but the use of coarser feed sizes (16–50 mm) was reported by Patzelt et al. [15]. At Argyle diamonds, (Australia), Maxton [23] reported charging feed size of 80% passing 75 mm with lumps up to 250 mm.

He outlines three simple rules behind properly sizing a jaw crusher. Rule #1: Identify maximum feed size. The size of the crusher opening directly determines the maximum feed size going into the crusher. For example, if the jaw has a 30-in. opening (gape), the maximum feed size should not exceed 80% or 24-in.

Hard ore Work Index 16 = 100,000/65,000 = 1.54 kwh/t. For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of 1.54 kw/t reduces the ball mill feed size to 6,500 micrometers. As a result, the mill output will increase with this reduced size to approximately 77,000 tons ...

Firstly, the feed size and capacity requirements should be taken into account. Cone crushers are generally used for smaller feed sizes and have a limited capacity, whereas gyratory crushers can handle larger feed sizes and have higher capacity. Secondly, the hardness and abrasiveness of the material being crushed …

Above 1,000 tph, primary gyratory crushers begin to look interesting, and after the throughput reaches 2,000 tph, jaw crushers are very rare, with the exception of a parallel plant layout. Capacity is also determined by the feed size and material type introduced to the plant, as well as the required product curve.

Blake jaw crushers, also as double toggle jaw crushers, are characterized by the position of the pivot of the swing jaw, which is located at the top of the machine. This design allows for a larger feed size and a higher capacity, making it suitable for primary crushing. The motion of the swing jaw in a Blake crusher is predominantly vertical ...

The approximate capacity of a jaw crusher for hard rock application at a typical setting may be obtained by multiplying the width by 10 to get tonnes per hour. For example, a 48 by 60 crusher will have a capacity in the order of 600 tph when crushing ore in a hard rock mine. ... The maximum feed size for a jaw crusher should be about 85% …

crusher components. • Small feed size increases wear at the bot-tom of the cavity and may cause poor uti-lization of wear parts. 2. Check the feed arrangement • In order to reach optimum capacity and maximize on the life of the wear parts, the crusher cavity should be full. • The feed must be distributed evenly across the crushing chamber ...

The capacity is similar to that of a jaw crusher with the same gape, and breadth 'B' equal to the perimeter of the gyratory crusher. Since all the coarse crushers have greater capacities than the devices for the finer ranges of size reduction, a gyratory crusher of sufficient size to crush the required size feed may have an excessive capacity.

The capacity range of primary crushers varies depending on the type of crusher and the size and hardness of the material being crushed. Generally, primary crushers have a capacity range of between 1,000 and 8,000 tons per hour. ... It is also important to ensure that the crushers are operated within their designed capacity and …

Crusher Feed Size and Roll Diameter.

High-capacity crushers have a lower reduction than slower speed but higher compression crushers. Know The Maximum Feed Size For Crushing. You cannot exceed the maximum allowable feed size for the cone crusher model. The feed size will depend on factors such as the closed side setting, eccentric throw, and head diameter.

Processing Capacity: A key differentiator is the processing capacity. Jaw crushers, designed for robust primary crushing, often handle larger volumes of raw material at a time. Cone crushers, tailored for secondary crushing, typically process smaller batches of pre-crushed material. ... Feed Size and Gradation: The size and gradation of the ...

Size reduction in an impact crusher relies on energy being conveyed into the rock from the rotor, and it begins with the feed. The initial impact is responsible for more than 60% of the crushing action, with the remainder being made up of impact against an adjustable breaker bar and a small amount of inter-particle collision.
