The present work uses a Particle Replacement Model (PRM) embedded in the software EDEM® to model and simulate operation of a laboratory-scale jaw crusher. The PRM was calibrated using data from single particle slow compression tests, whereas simulations of the jaw crusher were validated on the basis of experiments, with very good agreement.

Jaw Crusher Working Principle

In jaw crusher, another important analysis is breakage of the particle. In particle breakage model, two types of approach are used widely which are Ab-t10 and Tavares model.

Jaw crusher movement is guided by pivoting one end of the swinging jaw. and an eccentric motion located at the opposite end. [4] The size of a jaw crusher is designated by the rectangular or square opening at the top of the jaws .For instance, a 22 x 30 jaw crusher has an opening of 22" by 30", a 46 x 46 jaw crusher has a opening of 46" square.

Spherical DEM simulation of particle breakage in an industrial jaw crusher. The large red particle in image (a) is broken into a set of smaller daughter particles in image (b).

shown in fig.1 and a photograph is presented in fig.4. the jaw crusher operates at 340c/min. Fig.4- Jaw Crusher gouging wear test machine. The test wear plates and reference wear plate have a 20º to 23 º taper on each end for clamping to the jaw. All specimen surface are machined on a surface grinder. The small size of the specimens has a ...

Jaw Crusher. Jaw crusher is a kind of stone crusher machine which is widely used as primary or secondary crusher in stone crushing plant. The purpose is to reduce hard stone material to a small size that it can be transported by conveyors to the next crushing stages. 100-1200mm Feed Size. 5.5-280KW Motor Power.

jaw crusher, a particle, computer models, grinding ratio . Introduction . Shredding processes are widely used in human production activities and in the national economy. Currently, more than two billion tons of minerals are crushed and ground in the world every year, and by the number of employed people, the industries using crushing and ...

particle contained in the 63 / 53 mm range inside the jaw crusher chamber. The DEM simulation coupled to the PRM is capable to provide a valid qualitative representation of fragmentation observed in

1. Robust structure The fr ame is divided into two types: welding type and assembly type: small and medium specifications are welded and large specifications are assembled. 2. Superior cavity design The symmetrical "V"-shaped cavity design large bracket angle large stroke and reasonable speed enable larger feed size higher output more uniform particle size and reduced jaw wear.

In jaw crusher, another important analysis is breakage of the particle. In particle breakage model, two types of approach are used widely which are Ab-t10 and Tavares model.

A single toggle jaw crusher consists of an eccentric shaft that is placed on the top of the crusher. The rotation of the shaft along with the toggle plate generates the necessary compression force required to break down the substance into smaller particles. A single toggle jaw crusher has a better capacity than a double toggle jaw crusher.

The settings on a jaw crusher are designed to produce material ideal for secondary crushing. The best particle shape is typically found in material that is about the same size as the closed-side setting. Smaller sizes will contain a higher proportion of elongated particles because they have passed through the crusher without being touched ...

For a jaw crusher the thickness of the largest particle should not normally exceed 80–85% of the gape. Assuming in this case the largest particle to be crushed is 85% of the gape, then the gape of the crusher should be = 45.7/0.85 = 53.6 cm and for a shape factor of 1.7, the width should be = 45.7 × 1.7 = 78 cm.

jaw crusher 400x250

The jaw crusher is mainly used as a coarse crushing crusher, whose purpose is to crush the rock into smaller particle sizes for subsequent processing in the crushing section. Because it can effectively handle a large amount of hard rock, the jaw crusher is a popular alternative to the coarse crushing gyratory crusher

particle distributions in the products from operating crushers. Once established for a particular material in a particular crusher, they should be independent of the closed side set. This allows the crusher performance to be simulated at the various CSS. Model based on: 1. Whiten W.J. Walter G.W. and White M.E.

Application of jaw crusher Jaw crusher is mainly used to reduce the particle size of various materials. There are coarse crushing medium crushing and fine crushing. The first two are the main functions. The jaw crusher can crush more than 200 kinds of soft and hard ores or stones with a compressive strength of less than 300MPa.

Based on the current production line of artificial aggregate, the waste concrete derived from the same source was crushed by different crushing machine, jaw crusher and impact crusher. This paper focuses on the effect of different crushing machine on gradation and particle shape of recycled aggregate. As is shown by the results, recycled aggregate produced by two crushing …

600mm is the dimension across the jaw plates. 2.5 Crusher Sizing Jaw crushers are sized on the basis of the maximum particle size to be crushed and/or the tonnage rate to be crushed. Maximum particle size should not exceed 80% of the gape. For example, a 400- by 600-mm crusher will accept a maximum lump size of 400 by 0.8 = 320mm.
