Description
Application:
A small jaw crusher is a type of jaw crusher that is specifically designed for small-scale operations, laboratories, or where space and capacity constraints exist. These crushers are suitable for crushing small amounts of hard materials into smaller, more manageable pieces.
- Laboratories: For sample preparation and testing.
- Small-Scale Mining: For breaking down small amounts of ore.
- Construction: For on-site crushing of small quantities of building materials.
- Recycling: For crushing small amounts of concrete, asphalt, or other materials.
Key Components:
- Frame: The main structure that supports all other components.
- Fixed Jaw Plate: The stationary jaw that does not move.
- Movable Jaw Plate: The jaw that moves back and forth to crush material.
- Eccentric Shaft: Drives the movable jaw plate.
- Pitman: Connects the movable jaw plate to the eccentric shaft.
- Toggle Plate: Provides safety and adjusts the output size.
- Adjustable Discharge Opening: Allows for control of the size of the output material.
Working Principle:
- Material Feed: Material is fed into the top of the crusher through a hopper or feeder.
- Crushing Action: The movable jaw plate moves towards the fixed jaw plate, compressing the material in between. This action breaks the material into smaller pieces.
- Discharge: Once the material is crushed to the desired size, it exits through the bottom discharge opening.
Advantages:
- Compact Size: Ideal for small spaces and portable operations.
- Ease of Use: Simple design makes it easy to operate and maintain.
- Cost-Effective: Lower initial investment and operational costs compared to larger crushers.
- Versatile Applications: Suitable for crushing various materials, including rocks, ores, and concrete.
Maintenance:
- Regular Inspection: Check and replace wear parts like jaw plates and toggle plates.
- Lubrication: Ensure all moving parts are well-lubricated to reduce wear and tear.
- Adjustment: Regularly adjust the discharge opening to maintain the desired output size.
Safety Features:
- Overload Protection: Some models include safety mechanisms such as overload protection to prevent damage to the crusher if uncrushable material enters the chamber.
- Easy Access: Design allows for easy access to internal components for maintenance and cleaning.
