Design and production of an indigenous roll crusher from locally available materials for low hardness rocks was carried out in this work. The throughput capacity of the machine was 1.43tonnes/hour. The theoretical efficiency of the double roll crusher when crushing limestone was 60% while that of kaolin was 80%.

functioning Jaw crusher. Most of these components are discussed below. Moveable jaw stock The moveable jaw stock is the main moving part in a jaw crusher. It forms the moving side of the jaw, while the stationary or fixed jaw forms the other. It achieves its movement through the eccentric movement of the crusher main shaft. It is the back and

The TST is equipped with an efficient crushing motion, modular frame and a simple, low maintenance design to handle increasingly hard ores and remote site locations. Performance An often overlooked, but very important, characteristic of the single toggle jaw crusher is its kinematic design.

NEW CONE AND JAW CRUSHER DESIGNS G. P. Sobolev and V. G. Fedorov UDC 621.926.2 (047)(100) Original designs of cone crushers with hydraulic devices and double-jawed jaw crushers have been ... Jaw crushers with two jaw openings can be considered to be a completely new design. Jaw crushers are distinguished by reciprocating and …

The original Blake crusher was de­signed with a vertical stationary jaw. Probably the first departure from this arrangement was an 84 X 66″ crusher, built in 1914. This machine con­ventional design, in that the swing jaw was made vertical. Later, when the Superior line was developed, a compromise between these two ex­tremes was used in ...

4.4 Jaw Crusher Capacity Estimation. The capacity of jaw crushers is a measure of the mass or volume of crushed material produced in unit time of operation. The capacity is primarily a function of: 1. crusher design characteristics such as width and depth of the crushing chamber, 2. open and closed side settings, 3.

a) Maximum Feed Opening — 625MM (25 In.) b) Recommended Product Range — 100MM to 19MM (4 In. to ¾ In.) Short Head (Tertiary) Cone Crusher (Refer to Fig. 2): The Short Head Cone crusher is normally applied as a third stage crusher in plants designed for three or four stages of crushers.

1.) Obtaining the size or surface area required for the use of the ore or material. 2.) Allowing ease of transportation and storage. 3.) Separating the different minerals contained within the ore and to release them from one …

According to Chinese jaw crusher manufacturer's data [ 21 ], the PE 400 by 600 single toggle jaw crusher has 30 kW motor power and an input eccentric shaft speed of 275 rpm or 28.7979 radians per second. Assuming that the input speed is constant, the input torque is found to be 1.0417 kNm.

The moving jaw rotates around the eccentric axis as well as swings around the same center (Fig. 2).By removing the moving jaw suspension shaft and the front toggle plate of simple pendulum jaw crusher, and suspending the moving jaw on eccentric shaft to combine the connecting rod and the moving jaw into whole, a compound pendulum jaw …

The Jaw Crusher was first introduced by Eli Whitney Blake in 1858 as a double-toggle Jaw Crusher. Introduced in 1906, McLanahan's Universal Jaw Crusher was one of the first modern era overhead eccentric Jaw Crushers. On the overhead eccentric style Jaw Crusher, the moving swing jaw is suspended on the eccentric shaft with heavy-duty …

has to follow these three steps: crusher selection, crusher layout and process design. 2.4 Crushers . A crusher is a tool or machine that is used to reduce the size of a large solid particle to a smaller solid particle. The ore can have a size of up to 400mm. There are many types of crushers but the major ones are the jaw, gyratory and the cone ...

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. Generally primary jaw crushers have the square opening design, and secondary jaw crushers have rectangular opening design.

The crusher head is at the moment in the close-side position. Crusher Working Principle. As the head recedes on its opening stroke, the body of material moves downward; until, at the end of the stroke, the plane has moved to position "1.". Note that the length of line "1″ from concave to open-side head position, is the same as that of ...

A primary jaw crusher is typically of the square opening design whereas a secondary jaw crusher is of the rectangular opening design. Jaw Crusher reduces large size rocks or ore by placing the rock into compression. A fixed jaw board is the stationary breaking surface, while the movable jaw exerts force on the rock by forcing it against the ...

Jaw gyratory crushers – design and operating principle Technical data The main characteristic of jaw gyratory crushers is their enlarged feed opening which is located on one side of the crusher only. It is normally serrated and, to- gether with the upper part of the mantle, it forms the initial crushing zone. The

The width of the jaw determines capacity. Jaw crusher output gradation is controlled by the closed side setting. This is the adjustable opening at the bottom of the jaw. With a 24" top size limit and an 8:1 reduction ration, the closed side setting should be no smaller than 3". A well designed jaw should be 80 to 85 percent efficient.
