Is your crushing effect unsatisfactory? These few aspects might need adjustment.

When the material produced by the crusher is too coarse, uneven, or the efficiency is low, the problem is often not that the machine itself is "broken," but rather that its operating state is not optimized. Just like a chef cooking, the heat, ingredients, and knife skills all need to work together. When the crushing effect is unsatisfactory, you can troubleshoot and adjust the following key aspects one by one, which usually effectively solves the problem.

I. Checking the "Raw Materials": The Feeding Process is the Key Starting Point

The crushing effect primarily depends on what you "feed" into the machine.

Is the material consistent? If the hardness, moisture, or composition of the input material changes suddenly (for example, from dry limestone to wet clay or mixed with a large amount of soft impurities), the machine's crushing reaction will naturally be different. Try to maintain relatively consistent material properties.

Is the material size appropriate? If the raw material blocks are too large, the machine may not be able to "chew" them properly, resulting in large chunks in the output. Large blocks should be pre-crushed or fed in batches according to the machine's feed opening size. At the same time, avoid excessively fine material; too much fine powder will affect the normal "biting" and efficiency within the crushing chamber.

Is the feeding uniform and continuous? Feeding in an uneven, intermittent, or "burst" manner will cause the machine load to fluctuate, resulting in unstable crushing effects and easy clogging. Try to maintain a uniform and continuous feeding speed.

II. Adjusting the "Equipment": Precise Matching of Core Parameters

The machine itself has several key settings that directly affect the output particle size.

Output opening gap adjustment: This is the most common and direct adjustment method. For jaw crushers or some impact crushers, the product particle size can be controlled by adjusting the width of the output opening (discharge opening). A smaller gap results in finer output; a larger gap results in coarser output. Adjustment must be done with the machine stopped and the power off, following the steps in the equipment manual.

Speed and power matching: Check if the drive belt is loose or slipping, which will lead to insufficient rotor or jaw speed and reduced crushing force. Ensure that the motor voltage is normal and the power output is stable.

Screen inspection and replacement (if the equipment has a screen): The screen is the "gatekeeper" that controls the final particle size. Check if the screen is damaged, clogged, or has incorrect mesh size. Damage can cause coarse material to leak through, while clogging reduces output and efficiency. Select the appropriate screen based on the target particle size and clean it regularly.

III. Focus on "Wear": The condition of wear parts determines output

If the crusher's "teeth" are dull, it naturally won't be able to crush hard materials effectively.

Wear of core crushing components: Check the hammer heads, jaw plates, impact plates, and other parts that directly collide with the material. When these parts wear down, their edges become rounded, significantly reducing crushing capacity, leading to lower output and coarser particle size. Adjust their usage angle (e.g., reversing them) or replace them with new parts promptly.

Liner wear: Excessive wear of the liners inside the crushing chamber changes the chamber structure, affecting the flow and crushing trajectory of the material within the chamber, thus reducing crushing efficiency.

IV. Optimize the "Process": Ensure smooth flow and appropriate load

Is the discharge smooth? Check if there is any accumulation or blockage on the discharge conveyor belt or in the area below. Poor discharge can lead to excessive material accumulation in the crushing chamber, causing "blockage," which not only affects output and particle size but also increases equipment load.

Is the equipment load reasonable? Prolonged full-load or overload operation may prevent the machine from reaching its optimal crushing state due to overheating or insufficient power. Match a reasonable feed rate to allow the equipment to operate in its high-efficiency range.

In summary, when crushing performance is poor, we recommend you consider and check the following in order:

1. Is the raw material correct? (Check material hardness, size, and moisture content)

2. Are the machine settings correct? (Adjust the discharge opening gap, check the rotation speed and screen)

3. Are the "teeth" still sharp? (Check the wear of wear parts such as hammer heads and jaw plates)

4. Is the "digestion" smooth? (Ensure even feeding and smooth discharge)

Through this systematic troubleshooting and adjustment, you can usually find the root cause and restore the equipment to its ideal performance. Remember, fine adjustments and routine maintenance are often more economical and efficient than replacing large components.
