What is two-stage hammer crusher?

A two - stage hammer crusher, also known as a double - stage hammer mill. It is a type of stone crushing equipment used to reduce the size of materials. The screen grate bottom is not used in the design. There is no strict requirement for the moisture content of the material, and there is no phenomenon of clogging the sieve plate. Double rotor hammer crusher mill is suitable for crushing wet or sticky material, such as calcite, limestone, coal slag,furnace slag,ore slag in the brick plant, construction wastes,shale,coal gangue.

Two stage hammer crusher structure & components

Rotor: The rotor is the core component of the crusher. It consists of a shaft and hammers. The hammers are usually made of high - strength alloy steel to withstand the impact forces during the crushing process.

Crushing ChambersThere are two distinct crushing chambers in a two - stage hammer crusher. The first - stage chamber is designed to handle larger feed sizes and break the materials into intermediate - sized particles. The second - stage chamber is focused on further reducing the particle size and achieving a more refined product. The chambers are usually lined with wear - resistant materials such as manganese steel to protect the crusher body from abrasion caused by the materials.

Feed Hopper and Discharge Outlet: The feed hopper is located at the top of the crusher and is used to receive and guide the materials into the first - stage crushing chamber. The discharge outlet is at the bottom of the second - stage crushing chamber and is designed to allow the crushed materials to be discharged smoothly.

High Quality

High Crushing Ratio: It can effectively reduce large sized materials to very fine particles in a single pass through the crusher.
Customized Design

Fine and Uniform Product: It produces a relatively fine and uniform particle size distribution of the crushed materials.
Good Performance

Versatility: By adjusting rotor speed, it could meet crushing requirement both for It can soft and hard materials.

Product features

Efficient Energy Consumption: The integrated two - stage process reduces the need for additional material handling and transfer between different crushers, thus saving energy.

Working principle

First Stage: In the first stage, the materials are fed into the upper part of the crusher through a hopper. The rotor, which is equipped with hammers, rotates at a high speed. As the materials enter the crushing chamber, the hammers strike the materials with high - speed impact force. This initial impact breaks the large materials into smaller pieces. The crushing chamber of the first stage is usually designed with a certain shape and size to allow the materials to be effectively crushed and move towards the second - stage crushing area.

Second Stage: The partially crushed materials then fall into the second - stage crushing chamber. Here, the materials are further crushed by a combination of impact and grinding actions. At the same time, the materials are also ground between the hammers and the inner wall of the crushing chamber or against a grate bar. This two - stage process helps to achieve a finer and more uniform particle size distribution of the crushed materials.
