What are the characteristics of primary jaw crusher?

The primary jaw crusher is a machine used to crush blocks of mineral material (rock, ore, and gravel) into smaller pieces. Here are some of the characteristics of a primary jaw crusher:

1. High reduction ratio: The primary jaw crusher has a high reduction ratio, which allows it to break down large rocks into smaller pieces that can be processed further.

2. Simple structure: The primary jaw crusher has a simple structure that makes it easy to operate and maintain.

3. Uniform product size: The materials are crushed uniformly due to the crushing cavity shape and wide adjustment range of the discharge port.

4. Easy to adjust: The primary jaw crusher has an easy-to-adjust mechanism that allows users to adjust the size of the output material quickly.

5. Low operating cost: The primary jaw crusher has low operating costs due to its simple structure, easy maintenance, and low energy consumption.

6. Versatile applications: The primary jaw crusher is suitable for a variety of applications, including mining, metallurgy, construction, and more.

Here is a table detailing some technical specifications of a typical primary jaw crusher:

| Model | Feed Opening (mm) | Max Feeding Size (mm) | Adjustable Range of Discharge Opening (mm) | Capacity (t/h) |

|-------|------------------|----------------------|----------------------------------------|--------------|

| PE-600×900 | 600×900 | 480 | 65-160 | 90-180 |

| PE-750×1060 | 750×1060 | 630 | 80-140 | 110-320 |

| PE-900×1200 | 900×1200 | 750 | 95-165 | 220-450 |

In summary, the primary jaw crusher is a versatile and reliable machine that can reduce the size of large rocks into smaller pieces. Its characteristics include a high reduction ratio, simple structure, uniform product size, easy adjustability, low operating costs, and versatile applications.
