Small Jaw Crusher

New!

A small jaw crusher is a practical and efficient solution for crushing smaller quantities of material, making it ideal for specific applications in laboratories, small-scale mining, construction, and recycling.

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:

  1. Frame: The main structure that supports all other components.
  2. Fixed Jaw Plate: The stationary jaw that does not move.
  3. Movable Jaw Plate: The jaw that moves back and forth to crush material.
  4. Eccentric Shaft: Drives the movable jaw plate.
  5. Pitman: Connects the movable jaw plate to the eccentric shaft.
  6. Toggle Plate: Provides safety and adjusts the output size.
  7. Adjustable Discharge Opening: Allows for control of the size of the output material.

Working Principle:

  1. Material Feed: Material is fed into the top of the crusher through a hopper or feeder.
  2. 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.
  3. 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.
