The relation between transmission Angle and discharge port of compound pendulum jaw crusherDate: 2019-11-15 Views:
The relation between the transmission Angle of jaw crusher and the size of discharge port is seldom introduced in the existing data, so it is easy to be ignored by people.the relation between transmission Angle and discharge port of compound pendulum jaw crusher
1. Influence of transmission Angle on the performance of crusher
The crank connecting rod mechanism of jaw crusher is the key factor to determine the performance of crusher.The Angle between the connecting rod of jaw crusher and the bracket is called the transmission Angle, which has a great influence on the movement track and transmission efficiency of the jaw.
When the eccentricity is fixed, with the increase of the transmission Angle, the transmission efficiency is improved, the stroke ratio of moving jaw is also increased, the running characteristics of moving jaw are worse, and the wear of lining plate is intensified.When the transmission Angle decreases, the transmission efficiency also decreases, the moving jaw stroke ratio decreases, the moving jaw motion characteristics are improved, the lining wear is reduced, and the vertical upward component force of the elbow plate is increased, which is easy to accelerate the wear of guide rail on the elbow plate seat.
2. Relationship between transmission Angle and discharge port
The relationship between the drive Angle and the discharge port, which we will discuss here, refers to the relationship between the change of the size of the discharge port from MIN to MAX and the transmission Angle according to the requirements of product granularity.
The transmission Angle of the horizontally adjusted jaw crusher increases with the increase of the discharge port.
3. Calculation of transmission Angle
According to the calculation results, the transmission Angle of the horizontally adjusted jaw crusher increases with the increase of the discharge port, while when the jaw crusher is inclined to adjust, the transmission Angle decreases with the increase of the discharge port.The conclusion drawn from the previous schematic diagram is correct.
According to the above proofs, the variation rule between the discharge port and the transmission Angle is obtained. In other words, when the transmission Angle increases, the motion characteristics of the movable jaw become better and its crushing stroke decreases.When the transmission Angle decreases, the crushing stroke of the movable jaw increases and its motility becomes worse.
In the design of the crusher mechanism, according to the crusher different use requirements and focus direction, choose its transmission Angle and adjustment form.Generally, it is better to adopt the form of horizontal adjustment for larger transmission Angle, which is mostly used for jaw crusher with small power, low output and fine particle size.On the contrary, the small transmission Angle generally chooses the tilting type adjustment form, which is mostly used for high-power and high-output coarse jaw crusher.
