Comparison Of Simple And Compound Pendulum Jaw Crusher

According to the different movement methods of movable jaw plate, jaw crusher can be divided into simple pendulum jaw crusher and compound pendulum jaw crusher. The main components of these two types of jaw crusher are the same. They both formed by frame, eccentric shaft, pulley, flywheel, moveable jaw, toggle plate, side liner, fixed& movable jaw plate etc. In this article, we focus on the comparison of simple and compound pendulum jaw crusher.

Simple And Compound Pendulum Jaw Crusher Comparison

The up and down movement of movable jaw plate in compound pendulum jaw crusher can promote the discharging of crushed materials and suitable for crushing bulk materials. In this case, the efficiency of compound pendulum jaw crusher is higher than simple pendulum jaw crusher. Here we mainly talk about the comparison about their performance.

Advantages Of Compound Pendulum Jaw Crusher

• Its weight is relatively light and the structure is more compact.
• Raw materials in the crushing cavity can be crushed evenly, and the crushed materials will be discharged in the lower part of movable jaw, which makes the compound pendulum jaw crusher has higher efficiency. According to research, the efficiency of compound pendulum jaw crusher is about 20-30% higher than the efficiency of simple pendulum jaw crusher with same specification.
• Raw materials are crushed in the lower part of jaw plates and the content of cubical shaped final products is relatively higher than simple pendulum jaw crusher.

Weakness Of Compound Pendulum Jaw Crusher

The vertical swing amplitude of movable jaw plate is relatively large, which not only squeeze and crush raw materials but also have strong friction with the jaw plates. This will accelerate the damage of jaw plates.

Advantages Of Simple Pendulum Jaw Crusher

• The vertical stroke of simple pendulum jaw crusher is relatively small, which will reduce the damage of jaw plates.
• In the operation of simple pendulum jaw crusher, the toggle plate can produce strong propulsive force with applying less force on the link rod.

Weakness Of Simple Pendulum Jaw Crusher

• The structure is complicated.
• With same specification, simple pendulum jaw crusher is about 20-30% heavier than compound pendulum jaw crusher.
• The moving track of movable jaw plate in simple pendulum jaw crusher is not ideally. The horizontal stroke in the upper part is small while the horizontal stroke in the lower part in large. In this case, the efficiency of simple pendulum jaw crusher is lower.

For now, most investors adopt compound pendulum jaw crusher to process their raw materials. So manufacturers should focus on studying and optimizing compound pendulum jaw crusher.
