2. THEORETICAL DETERMINATION OF THE OPTIMAL ANGULAR VELOCITY OF THE ECCENTRIC SHAFT OF JAW CRUSHERS Fig. 1 shows a drawing of a jaw crusher with an eccentric shaft. When the moving jaw is removed from the static [4], the crushed product is freely discharged through the disharge port of the crusher under its own weight. With each move

Figure 1. Kinematical scheme and kinematic parameters of single-toggle jaw crusher 3. Capacity determination methods To date, many theoretical, empirical and semi-empirical dependencies for approximate evaluation of a single-toggle jaw crusher capacity have been proposed. The generalization of these dependencies is proposed in [17]

A jaw crusher breaks minerals, ores of high strength. The stiffness of swing jaw plate has not been varied with changes in rock strength. Thus stiffness of swing plate is enough to crush taconite with an unconfined compressive strength (Q U ) of up to 308 MPa, may be over signed for softer fragmental. Hence the weight of the swing plate is necessary to reduced

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

Jaw crushers reduce large rocks or ore by means of compression. Mechanical pressure is applied using the crusher’s two jaw; one is fixed while the other makes an eccentric movement. There are also primary and secondary types of these crushers. Jaw crushers are one of the most commonly preferred crushers due to their ability to crush all kinds

The disadvantage of this type of crusher, when high capacity is required, is the relatively small discharge width, limiting the capacity as compared with the discharge circuit of a gyratory crusher. Jaw crushers are mainly used in plants producing up to approximately 1600

Jan 01, 2016 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

Although jaw crushers are extensively used for a variety of materials, their operational characteristics are not well understood. This lack of understanding makes selection of the proper machine difficult. Hersam (1923) proposed a method for calculating capacities using a Dodge-type jaw crusher
