What Is Double Rotor Hammer Crusher?

A double rotor hammer crusher, also known as a two-rotors hammer mill crusher. 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.

Double Rotor 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.

Working principle

The operation of a double rotor hammer crusher relies on impact, shearing, and grinding. It destroys rock using high-speed kinetic energy. The process occurs in three distinct stages:
Stage 1: The First Rotor
Material is fed into the machine from the top. It immediately encounters the first high-speed rotor. The hammers attached to this rotor strike the material with massive force, breaking large rocks into medium-sized chunks.

Stage 2: The Second Rotor
The crushed material from the first rotor is thrown directly into the path of the second rotor (which often rotates at a higher speed). Here, the material is pulverized further into fine particles.

Stage 3: Mutual Crushing and Discharge
A unique feature of this design is that materials are not just hit by hammers; they also collide with other flying rocks and the inner liners of the machine. Finally, the crushed material falls through the discharge opening at the bottom.
