Equipment Introduction:
A hammer crusher is a material crushing equipment that breaks materials through impact, available in two types: single-rotor and double-rotor. It directly crushes materials with a maximum particle size of 600-1800 mm to 25 mm or below in a single crushing process.
Applications:
Suitable for crushing medium-hard materials in cement, chemical, power, metallurgy and other industrial sectors, such as limestone, slag, coke, coal, etc., for medium and fine crushing operations.
Types:
1. Single-rotor crusher: Further divided into reversible and irreversible types.
2. Double-rotor crusher: Features two rotors for enhanced crushing efficiency.
3. Widely Used Models: Single-rotor hammer crushers and ring hammer crushers are most commonly applied due to their reliability and adaptability in various crushing scenarios.

Working Principle:
The hammer crusher primarily relies on impact energy to crush materials. During operation:
1. The motor drives the rotor to rotate at high speed, while materials enter the crushing chamber uniformly.
2. High-speed rotating hammer heads impact, shear, and tear the materials to break them down.
3. The materials' own gravity forces them from the rotating hammer heads toward the baffle and screen bars inside the frame.
4. Below the rotor, a screen plate is installed. Particles smaller than the screen holes fall through for discharge, while oversized materials remain on the screen plate, continuously struck and ground by the hammers until they reach the required size before passing through the screen plate.
Key Components of Hammer Crusher
1. Frame (Crusher Housing)
Composed of the lower body, rear upper cover, left sidewall, and right sidewall, connected by bolts. Features a top-mounted feed inlet and fully lined with high-manganese steel wear plates. The lower body is welded from carbon structural steel, with high-manganese steel welded bearing supports for the rotor. The frame supports the entire equipment's weight and structural integrity.
2. Transmission System
The motor drives the main shaft directly via an elastic coupling. The shaft is supported by spherical self-aligning roller bearings housed in bearing blocks on both sides of the frame.
3. Hammer Heads
The primary crushing components, their quality, shape, and material determine the crusher's productivity. Hammer kinetic energy is proportional to weight-heavier hammers deliver higher efficiency. Typically cast from a premium multi-element high-chromium manganese steel composite, extending service life several times compared to standard hammers.
Key Components of Hammer Crusher
4. Rotor Assembly
The core working unit, consisting of a main shaft, hammer discs, pins, and hammers. Hammers are arranged in three rows, suspended between discs by pins. End discs and locknuts prevent axial movement of the hammers and discs.
5. Impact Liners
Subjected to material impact and abrasion during operation, these liners are cast from high-manganese steel, quenched, and strengthened to ensure superior wear and impact resistance.
6. Screen Plate
Comprising an arc-shaped screen frame and screening plates, positioned below the rotor to separate crushed materials by size.
