The jaw crusher is usually used as a head crusher in the production line, and its production volume directly affects the output of the entire production line. How to increase the production capacity of the crusher with a large bottom limit while ensuring the particle size distribution of iron ore is a difficult problem that many mining enterprises are very concerned about. Today, the editor will share the methods to increase the production capacity of jaw crushers. Seizing these 6 points is crucial to easily increase the production capacity of jaw crushers.

1. Proper feeder

To promote uniform damage to the jaw plate and reduce operating costs, iron ore should be distributed along the channel of the vibrating feeder and filled with the crushing chamber.

2. Ensure sufficient ore reserves

During all normal applications of the vibrating feeder, according to the requirements of the output rate size, within the range of the rated vibration amplitude, the vibration amplitude is adjusted according to the control cabinet knob, thereby achieving the goal of infinitely adjusting the output rate of the vibrating feeder.

3. Adjustment of the opening of the feeding port

Adjusting the opening of the discharge port means maintaining it by adjusting the sealing gasket located behind the swing bar seat plate by lifting or lowering it. When accurately measuring and setting the spacing, pay attention to the position of the upper eccentric axis, so that the lower part of the fixed jaw plate and the lower part of the moving jaw plate are in the closest position. At this position, accurately measure the larger diameter of one circle that is tangent to the two jaw plate circles. Using this circle means the specification of the iron ore. Accurate measurement equipment should be equipped with environmental gauges supplied with the equipment. After adjustment, the tightening of the elastic yellow cannot be reduced too much, and it is necessary to prevent the dense arrangement of elastic yellow. The support frame and the tension spring yellow both bear the fatigue stress effect and should be replaced by the end of this year.

4. Jaw plate damage situation and solutions

It is best to regularly maintain the condition of damaged jaw plates and distinguish when to invert, exchange, and replace them. There are several common types of damage and solutions:

(1) 1/3 of the bottom of the jaw plate is damaged; The bottom of the jaw plate is 2/3 damaged. Solution: The two jaw plates are reversed.

(2) The top and bottom of the jaw plate are both damaged by 1/3, and the central and southern parts are damaged by more than half; The top and bottom of the jaw plate are both damaged by 2/3. Solution: Swap the two jaw plates.

(3) The top and bottom of the two jaw plates have been completely damaged. Solution: All disassembly and replacement.

5. The key practical significance of Runhua

High quality lubrication is crucial to ensure the characteristics and service life of rolling bearings, which are crucial components for the operation of crushers and are closely related to crushing efficiency.

6. Moisturizing point and amount of fat added

The eccentric shaft rolling bearing installed on the motor shaft rolling bearing box and moving jaw is the only component that must be lubricated in the jaw crusher. The shredder weapon is equipped with a labyrinth sealing device to maintain the cleanliness of vegetable oil in the rolling bearings. Four rolling bearings are equipped with lubricating grease nozzles on both sides for the purpose of adding lubricating grease. Before adding lubricating grease, the fuel injector and oil gun should be cleaned to prevent dust from entering the rolling bearing housing.
