Several rows of hanging hammers are installed on the main shaft of the crusher. A pin shaft runs through the pin hole in its circumference, and the hammer is hinged between each row of hanging hammer bodies with the pin shaft. After the hammer is worn, the working surface can be replaced. There are two trapped pin holes on the hanging hammer body. The distance from the center of the pin hole to the center of the rotation axis is different, which is used to adjust the gap between the hammer and the grate. In order to prevent the hanging hammer body and the hammer from moving in the platinum direction, the two ends of the hanging hammer body are fixed with pressing hammer discs and locking nuts. It is supported on rolling bearings at both ends, and the bearings are fixed on the casing with bolts. The main shaft and motor are directly connected with elastic coupling. To make the rotor run smoothly, a flywheel is mounted on one end of the main shaft.
Types of hammer mill is mainly used for crushing medium-hard or brittle materials with hardness not more than 300Mpa and 15% moisture,such as coal, cement,gypsum,alumen,brick,tile,limestone,etc.It has the features of simple structure, big crushing ratio, high production efficiency, uniform particle size, etc. This equipment can be adjusted to reach various discharged granularity as the customers' requests.
Hammer crusher is the most common of stone crushing equipment. It is also called hammer mill. It has high production capacity, low energy consumption, simple structure, reliable quality, easy maintenance, etc.
Feature
(1) The working hammer head is cast by new technology, which is wear-resistant and impact-resistant.
⑵According to customer requirements, adjust the required granularity.
(3) The structure of the hammer crusher is sealed, which solves the problem of dust pollution and ash leakage in the crushing workshop.
⑷ The overall design has the advantages of beautiful appearance, compact structure, few wearing parts, and convenient maintenance. It is an upgraded product.
⑸Compact structure, beautiful appearance, good wear resistance and easy maintenance.
How it works
The arc-shaped discharge screen is installed under the rotor, the two ends of the grate are installed on the beam, and the grate outside the member is pressed by the pressure plate, and the arrangement direction of the grate is perpendicular to the movement direction of the rotor. The grate gap is formed by the protruding part in the middle of the grate. In order to facilitate material discharge. The gap of the grate gradually expands downward, and at the same time it is inclined to the rotation direction of the rotor.
Motor drives the rotor quickly in the crushing cavity. Raw materials enter the crusher through the feeding inlet and are impacted, cut and ground by high-speed hammer heads. There is a grate under the rotor assemblly, so that materials with size smaller than the grate mesh will be screened out and others are left to be further hammered until they reach the standard size. The size of the final product can be adjusted by changing the grate, the gap between the rotor assemblly and the grate can also be adjusted according to different requirements.
