Processing ore with sticky soil in a crusher can be challenging, as the sticky material tends to clog and adhere to the equipment, reducing efficiency and potentially causing downtime. Here are some strategies to handle it effectively:
-
Pre-Screening:
- Use a Grizzly Feeder: Prior to the primary crusher, a grizzly feeder can separate larger rocks from finer particles that include sticky soil, reducing the load on the primary crusher.
- Wet Screening: Implementing wet screening can help to wash away some of the sticky material before it reaches the crusher.
-
Conditioning and Mixing:
- Blending Techniques: Mix the sticky ore with dry or less sticky material to reduce the overall stickiness and facilitate smoother processing.
- Material Conditioning: Employ techniques like adding lime or other conditioners to the ore to reduce its stickiness.
-
Crusher Design Considerations:
- Open Design Crushers: Use crushers designed with an open rotor and large infeed openings to reduce the chance of clogging.
- Clearing Mechanisms: Ensure the crusher has mechanisms to clear blockages quickly, such as hydraulic release systems.
-
Regular Maintenance:
- Frequent Cleanouts: Schedule regular cleanouts of the crusher to remove any buildup of sticky material.
- Lubrication: Keep the moving parts well-lubricated to minimize the material sticking to them.
-
Operational Adjustments:
- Adjust Feed Rate: Slow down the feed rate to give the crusher more time to process the sticky material.
- Monitor Crusher Settings: Continuously monitor and adjust the crusher settings to optimize performance based on the stickiness of the material being processed.
-
Environmental Controls:
- Maintain Moisture Control: If possible, control the moisture content of the ore to reduce stickiness, either by allowing it to dry if feasible or using water sprays to keep fine particles from binding.
-
Auxiliary Equipment:
- Install Log Washers: Log washers or scrubbers can be used to break down and wash away sticky materials from ores before crushing.
Implementing a combination of these methods can significantly improve the efficiency of processing ore with sticky soil in a crusher.
