Product Description:
Hammer crushers utilize high-speed rotating hammers to impact, shear, and tear materials, and achieve secondary crushing through the collision of materials with impact liners. Their characteristics include a large crushing ratio (capable of crushing large pieces of material into small particles in a single pass), compact structure, and high production capacity.
Based on the number of rotors, they are mainly divided into two types: single-rotor and double-rotor. To adapt to different working conditions and materials, various sub-types have also been developed, such as single-stage heavy hammer crushers, reversible crushers, and ring hammer crushers.
Features:
-High crushing ratio, simplified process: Single-stage hammer crushers can crush large pieces of ore to the required particle size in one pass, eliminating the need for secondary crushing and significantly reducing investment costs.
-Effectively solves clogging problems: For high-moisture materials, dual-rotor and reversible models adopt a "screen-bar-less grate bottom" design, fundamentally eliminating the persistent problem of clogging caused by wet materials in traditional crushers, achieving stable operation in all weather conditions.
-Uniform and controllable output particle size: By adjusting the gap between the hammer and the screen plate (or impact plate), or by replacing the screen plate with one of different aperture sizes, the output particle size can be precisely controlled, flexibly meeting different production needs.
-Low operating costs and easy maintenance: High-wear-resistant alloy hammers extend the replacement cycle. Some models are designed with a hydraulic control system and a side-opening maintenance door, allowing a single person to quickly complete hammer replacement and routine maintenance, reducing downtime.

Applications:
The hammer crusher is a general-purpose equipment that uses the impact energy generated by high-speed rotating hammers to crush materials. It is widely used in industries such as mining, building materials, and brick and tile manufacturing. It can crush large raw materials to the required fine particle size in one pass and is a key crushing equipment in the production line.
Working Principle:
Hammer crushers primarily rely on impact energy to perform crushing operations:
-Feeding and Impact: The motor drives the rotor to rotate at high speed. Material enters the crushing chamber from the feed inlet and is immediately subjected to violent impact from the high-speed rotating hammers, achieving initial crushing.
-Impact and Rebound: The impacted material gains enormous kinetic energy and flies at high speed towards the impact liner on the casing, resulting in secondary impact crushing.
-Grinding and Discharge: Under its own gravity and the drive of the hammers, the material falls onto the screen plate. Material of suitable particle size is discharged through the screen holes; larger particles are blocked by the screen plate and remain in the chamber to continue being struck and ground by the hammers until they are within acceptable limits.
The hammer crusher is mainly composed of the following core components:
Rotor assembly: The core working component of the equipment, consisting of the main shaft, hammer disc, and pin shaft. The spindle is made of high-quality alloy steel and bears a huge impact torque.
Hammer head: a vulnerable part that comes into direct contact with the material, and its quality and material directly determine the crushing efficiency. Usually, wear-resistant alloys such as high chromium manganese steel are used for composite casting to extend their service life.
Rack (box): composed of upper and lower racks, using a welded steel plate structure, with high manganese steel lining on the inner wall to protect the casing from wear and tear.
Counterattack lining plate (striking plate): Installed around the rotor, the material is struck by a hammer and hits the lining plate, achieving secondary crushing.
Screen plate (grate): located below the rotor, controls the particle size of the discharged material. Materials that do not meet the standards will be blocked by the sieve plate and continue to be repeatedly ground by the hammer until the particle size is qualified before being discharged. Some new models have adopted a "grateless bar" design to completely prevent blockages.
