1. Introduction

Gyratory crusher is a common crushing equipment, widely used in mining, construction, metallurgy and chemical industry. It shears, grinds and impacts materials in a bidirectional rotation to achieve the purpose of crushing. This article will give a detailed introduction to the structural composition and working principle of the gyratory crusher.

2. Structural composition

1. Main unit: The main unit of the gyratory crusher is its core component, which consists of a motor, a reducer, a bearing, a rotor and a crushing chamber, and is the key part of the entire equipment.

2. Feed port: The feed port of the gyratory crusher is usually located at the top of the main unit, and consists of a feed pipe, a feed port protection plate and a feed roller, which allows the material to enter the crushing chamber smoothly.

3. Discharge port: The discharge port of the gyratory crusher is divided into two forms: a positive discharge port and a side discharge port, which can discharge the crushed material.

4. Dust collector: In order to reduce the pollution of dust to the environment, some gyratory crushers are equipped with dust collectors, which can collect dust to achieve the purpose of reducing pollution.

5. Control system: The control system of the gyratory crusher usually includes a control cabinet, buttons and signal indicators, etc., which can control and monitor the equipment.

3. Working principle

The gyratory crusher mainly shears, grinds and impacts the material under the action of axial and circumferential bidirectional rotation to achieve the purpose of crushing. The following is the working principle of the gyratory crusher:

1. Material enters the crushing chamber: The material enters the crushing chamber of the gyratory crusher through the feed port, and is subjected to bidirectional rotation in the crushing chamber, and is crushed by several groups of reamers, hammers and impact plates.

2. Repeated crushing of materials: The material is repeatedly crushed in the crushing chamber to achieve the purpose of crushing.

3. Discharge of crushed materials: The crushed material is discharged from the discharge port after being screened by the sieve, and the dust is discharged along the air outlet or collected by the dust collector.

In the whole process, the bidirectional rotation, reamer, hammer, impact plate, etc. of the gyratory crusher play an important role in grinding and impacting the material to meet the production needs.

IV. Conclusion

Gyratory crusher is a kind of crushing equipment widely used in mining, construction, metallurgy and chemical industry. Its main structure includes main machine, feed port, discharge port, dust collector and control system. It shears, grinds and impacts materials in a bidirectional rotation to achieve the purpose of crushing.
