The basic structure of a jaw crusher includes the fixed jaw plate, movable jaw plate, toggle plate, eccentric shaft, flywheel, etc. 1. Fixed jaw plate. ... Bearing: Support the rotating components of the jaw crusher, such as the eccentric shaft and flywheel. Tension rod: Control the movement of the movable jaw and prevent it impact the front ...

The pitman is generally given a nearly vertical motion by the eccentric shaft, and since one of the toggles is mounted in rigid state at one end of the crusher frame (Fig. 4.2 A), the reciprocating motion of the pitman causes the other toggle to move the jaw back and forth. Crushing is accomplished only when the swinging jaw moves towards the ...

Jaw breakers use an eccentric shaft to make the jaw move an inch and a half, at around 400 rpm. That makes 1500 engine rpm with a 540 rpm PTO. So i dont know if it will be direct drive with just a torsion damper to get maximum fuel efficiency, or with a 1:1.25 reduction so the tractor engine can run at 1900 to 2000 rpm to get more power.

Average throughput rate of single-toggle jaw crusher, standard version, tolerance ± 10% Double-toggle jaw crushers Design Double-toggle jaw crushers are equipped with a double-toggle system, which is con - trolled by a pitman that moves up and down under the influence of an eccentric shaft, causing the toggle plates to alternately flex and ...

performance parameters of single toggle jaw crusher. Jaw plate wear has considerable effect on the life of jaw Crusher which is caused by the slipping motion between the fed material and the jaws. This wear is predominantly serious in the fixed plate and hence the liners of the fixed jaw should be properly chosen. In addition to this the

correspond to eccentric shaft, toggle plate, moving jaw respectively in crusher. The mechanism diagram of PE1500×1800 single toggle jaw crusher is shown in figure 3, and its structure size is: crank length L 1 = 32mm, connecting rod length L 2 = 2730mm, rocker length L 3 = 895mm, frame length L 4 = 2290mm.

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 ...

Jaw crusher is one of the main types of primary crushers in a mine or ore processing plant. The size of a jaw crusher is designated by the rectangular or square opening at the top of the jaws (feed opening). For instance, a 24 x 36 jaw crusher has a opening of 24" by 36", a 56 x 56 jaw crusher has a opening of 56" square.

The movable jaw, which is supported from the top by an eccentric shaft, is connected to the tension arm and an angled built-in support plate that absorbs the cyclic loads in the lat section. Jaw crushers are used as the primary crushers in the first stage of a crushing process for the breaking of large-sized rocks, while jaw crushers with ...

It is mainly composed of frame, liner, end liner, mandrel, eccentric shaft, toggle plate, movable jaw tensioning device (pull rod, pull rod seat), pulley, and flywheel (Fig. 1). The fixed jaw plate, the movable jaw plate, and the …

Eccentric shaft This is made of hardened steel (high carbon steel). It put the moveable jaw stock in motion as a result of the eccentric lobe on the shaft as shown in Figure 2 It is this motion that produces the needed force to crush materials. Figure 2: Eccentric shaft. Moveable jaw (manganese die) Figure 3: Moveable jaw.

The jaw crusher above is designed for the motor sizes listed in RPG and technical specifications. This means that for harder materials, the crusher will have to be operated at larger settings to avoid overload of drive and/or motor. Using oversized motors will lead to radically shorter crusher life and various mechanical problems.
