What is an Hammer Crusher

hammer crusher design

Hammer stone crusher is a kind of equipment that crushes materials in the form of impact. Crushing the size of 600-1800 mm material to 25m or less. Hammermill machine can not only be used in stone crusher plant, sand plant, but also can replace the cone crusher in the mineral processing.

Crusher parts: upper body, grate plate, middle, discharging mouth, hammer, side plate, stand, hammer axle, liner.

JXSC hammer mill machine that hammerhead adopts a new technology cast which wear-resistant and impact-resistant. The airframe structure of the hammer mill is seal which solves the problems of dust pollution and dust leakage in the crushing workshop. And it is easy to maintain.

Hammer Crusher Benefit

JXSC hammers machine features

1. Hammerhead uses new cast technology which with wear-resistant and impact-resistant characteristic.
2. Can adjust the granularity size.
3. The seal structure that solves the problems of dust pollution and dust leakage in the crushing workshop.
4. The overall design of hammer crushing equipment has the advantages of beautiful appearance, compact structure, few wearing parts, convenient maintenance, etc.

Types of hammer crushers

The hammer rock crusher is divided into single-stage, high-efficiency Hammer crushing machine, and vertical shaft, reversible, ring, swing, double rotor hammer crusher equipment.

    1. According to the number of rotors, divided into the single rotor and double rotor two categories.
    2. On the basis of rotation direction, divided into irreversible and reversible two types.
    3. According to the arrangement of the Hammer, divided into the single-row type and multi-row type two categories. The former hammer machine is mounted on the same rotary plane, while the latter mining hammer is distributed on several rotary planes.

Hammer Crusher Working Principle

Hammermill crusher mainly rely on impact energy to complete the crushing of materials. When the hammer mill rock crusher works, the motor drives the rotor to rotate at high speed, and the material enters the crusher cavity evenly. The hammerhead with high speed turns impacts and tears the material lead to the materials are crushed.

At the same time, the material from the high-speed rotating hammerhead to the baffle and screen strip in the frame under the gravity effect. The material larger than the size of the screen hole remains on the screen plate and continues to be hit and ground by the Hammer. Then finally through the sieve plate discharge machine until the crusher material size discharge.

Why Hammer Crusher

The advantages of the hammer: ① The ratio of crushing is large, generally is 10-25, high up to 50. ②High production capacity. ③uniform products. ④Less over-powder phenomenon. ⑤Simple structure, light equipment quality. ⑥Simple operation and maintenance, etc. The series hammer crusher products are suitable for crushing all kinds of medium hardness and brittle materials, such as limestone, coal, salt, gypsum, alum, brick, tile, coal gangue and so on. The compressive strength of the crushed material shall not exceed 150 MPA.

The series of crushers are mainly used in cement, coal preparation, power generation, building materials, and compound fertilizer industries. It can crush the raw materials of different sizes into uniform particles for the next working procedure. Reliable mechanical structure, high production efficiency, good applicability.

But the hammer crusher also has some disadvantages, such as the hammer and grate screen wear quickly. When crushing hard materials, they wear out faster. When crushing sticky wet materials, it is easy to plug the screen seam of the grate. Therefore, it is easy to cause shut down, so the moisture content of the material should not exceed 10 %. When milling hard objects, the hammer and lining plate have big wear. And the consumptive metal material is much, often needs to replace the wear-and-tear piece.
