komponen tertiary direct drive crusher

The Tertiary Direct Drive Crusher is a type of crusher used in the mining and aggregate industries for fine crushing or shaping applications. Below are its key components and their functions:

Main Components of a Tertiary Direct Drive Crusher:
1. Rotor
– The primary rotating component that delivers high-speed impact to the feed material.
– Typically fitted with wear-resistant hammers or blow bars.

2. Blow Bars (Hammers)
– Replaceable wear parts attached to the rotor that crush the material upon impact.
– Made from high-chrome or manganese steel for durability.

3. Direct Drive Motor
– Eliminates the need for belts or gear reducers by directly coupling the motor to the rotor shaft.
– Provides higher efficiency and reduced maintenance compared to V-belt drives.

4. Crushing Chamber
– Enclosed space where material is crushed between the rotor and breaker plates/anvils.
– Designed for optimal impact crushing with minimal fines generation.

5. Adjustable Breaker Plates (Anvils)
– Stationary plates that help shape and refine the crushed product.
– Can be adjusted to control product size and gradation.

6. Feed Hopper & Feed Tube
– Guides incoming material into the crushing chamber at an optimal angle for efficient impact crushing.

7. Hydraulic or Mechanical Adjustment System
– Allows adjustment of breaker plate gaps to fine-tune product size without stopping operation.

8. Base Frame & Housing
– Provides structural support and encloses moving parts for safety.

9. Wear Liners
– Protective liners on internal surfaces to resist abrasion from processed material.

10. Bearings & Shaft Assembly
– Supports high-speed rotor rotation with minimal friction (often heavy-duty spherical roller bearings).

11. Discharge Conveyor (Optional)
– Transporcrushed material away from the crusher for further processing.

Advantages of Direct Drive in Tertiary Crushers:
– Higher energy efficiency (no power loss through belts/pulleys).
– Reduced maintenance (no belt replacements or tensioning).
– Compact design with fewer moving parts.

Applications:
– Fine crushing in quarries (producing cubical aggregates).
– Manufactured sand production.
– Recycling (concrete, asphalt).
