The three types of crushers most commonly used for crushing CDW materials are the jaw crusher, the impact crusher and the gyratory crusher (Figure 4.4).A jaw crusher consists of two plates, with one oscillating back and forth against the other at a fixed angle (Figure 4.4(a)) and it is the most widely used in primary crushing stages (Behera et al., 2014).
Apr 07, 2016· The maximum feed size varies with each model but is generally limited to 609mm (24) to 914mm (36). The output gradation of the primary HSI crusher is generally coarser than the primary breaker due to the lack of expansion above the rotor, which also affects the capacity.

May 13, 2019· Size reduction in an impact crusher relies on energy being conveyed into the rock from the rotor, and it begins with your feed. The initial impact is responsible for more than 60 percent of the crushing action, with the remainder made up of impact against an adjustable breaker bar and a small amount of inter-particle collision.
Sep 29, 2019· Jaw crusher is generally used as the primary crusher in the crushing circuit and connects to the ore feeding machine. In the early years, common used plate feeder, but now, the vibrating feeder is more popular. Practice has proved that the vibrating feeder has advantages of low power consumption, strong transportation capacity, low failure rate and easy maintenance, which can
For instance, if the final size of your product only needs to be between 4 inches and 6 inches, a primary jaw or impact crusher can accomplish your goals. However, you will likely require a much finer product, and that means incorporating up to threeor even fourstations with a variety of crusher types. 1. Primary Crushing

PRIMARY CRUSHING A 63 x 118 gyratory crusher receives ROM of up to 1 m in size and reduces it to less than 125 mm. A variable speed belt feeder delivers ore from the crusher chamber to the coarse ore stockpile feed conveyor. The site mobile crane is used for major crusher maintenance.
Jaw Crushers are sized by the top opening of the crushing chamber. For example, a 32 x 54 Jaw Crusher measures 32" from jaw die to jaw die at the top opening or gape opening and 54 across the width of the two jaw dies. The narrower bottom opening of the crushing chamber is used to size the discharge material.
This angle depends on the size, hardness and frangibility of the material. It cannot be selected as too large or too small. The nip angle in primary crushers is lower than in secondary crushers. Generally, this value is between 18 and 24 degrees in primary jaw crushers, and between 22 and 28 degrees in secondary crushers.
Because each crusher type has a limited reduction capability, sometimes several stages of crushing are needed to achieve the desired final product size. Primary crushers are important for kicking off production and initial product sizing for further processing. They receive the material directly from the blasting, drilling or dredging process.
2.1 The primary crusher. The primary crusher is located in the quarry and consists of a McLanahan 48x72 Shale King Crusher rated at 1,000 TPH (Tons Per Hour). The driving flywheel has a diameter of 2.5 meters and is motor driven through six v-belts.
Primary crushing reduces the large pieces to a size which can be handled by the downstream machinery. Some crushers are mobile and can crush rocks as large as 1.5 meter (60 inches). Primarily used in-pit at the mine face these units are able to move with the large infeed machines (mainly shovels) to increase the tonnage produced.

Maintenance of the wear components in both gyratory and cone crushers is one of the major operating costs. Wear monitoring is possible using a Faro Arm (Figure 6.10), which is a portable coordinate measurement machine.Ultrasonic profiling is also used. A more advanced system using a laser scanner tool to profile the mantle and concave produces a 3D image of the crushing chamber (Erikson, 2014).
Jaw Crushers 7 The BB 50 is designed for a very efficient and convenient size reduction pro-cess. The variable speed can be set between 550 and 950 min-1 to adapt the crushing process to sample requirements. The possibility to reverse the rotat- ing direction is helpful if too much sample material has been fed to the crusher causing it to block.
