Jaw crusher
Jaw Crusher Overview
The jaw crusher, also known as the "tiger's mouth", is a widely - used primary crushing equipment in the mining, construction, and other industries. It is designed to break large rocks and ores into smaller pieces for further processing.
Working Principle
The working part of a jaw crusher consists of two jaws: a fixed jaw and a movable jaw. The fixed jaw is vertically (or slightly outward - inclined at the top) fixed on the front wall of the machine body, while the movable jaw is inclined and forms a crushing chamber with the fixed jaw, which is wider at the top and narrower at the bottom. The movable jaw makes periodic reciprocating movements towards the fixed jaw. When the two jaws separate, materials enter the crushing chamber; when they get closer, the materials between the two jaws are crushed by extrusion, bending, and splitting forces.
Features
High Crushing Ratio and Uniform Product Size: It can achieve a large reduction ratio, and the final product has a relatively uniform particle size.
Simple Structure and High Reliability: Composed of basic components such as the frame, eccentric shaft, flywheel, and jaws, it has a simple structure, which makes it reliable in operation and easy to maintain.
Low Operating Costs: With a simple design, it requires less maintenance and has lower energy consumption, resulting in relatively low operating costs.
Low Noise and Dust: Advanced design and sealing technology help to reduce noise and dust emissions during operation, which is more environmentally friendly.
Adjustable Discharge Opening: The size of the discharge opening can be adjusted to meet different production requirements.
Applications
Jaw crushers are suitable for crushing various hard and medium - hard materials with a compressive strength of up to 320 MPa, such as granite, limestone, basalt, and ore. They are widely used in industries like mining, metallurgy, building materials, highways, railways, water conservancy, and chemical engineering.
Capacity
The processing capacity of jaw crushers varies depending on the model and specifications, generally ranging from 50 to 1500 tons per hour. Different models can be selected according to specific production needs.
In summary, the jaw crusher is a powerful and efficient crushing equipment that plays a crucial role in the industrial production process.
Overview of PEV - Jaw Crusher
The PEV - Jaw Crusher is a high - performance crushing machine that has made significant contributions to the field of material processing.
Design and Technology
The PEV - Jaw Crusher is a new product that absorbs world - advanced technology. It is developed based on the existing traditional jaw crushers and adopts three - dimensional design theory. This design approach allows for a more optimized structure, which not only enhances the crusher's performance but also makes it more adaptable to different working conditions.
Working Principle of GC Series Jaw Crusher
The GC series jaw crusher is a widely - used crushing equipment in the mining, construction, and other industries. Its working principle is based on a simple yet effective mechanical design that enables it to break down large - sized materials into smaller pieces.
1. Structural Components
The main components of the GC series jaw crusher include a fixed jaw, a movable jaw, an eccentric shaft, a toggle plate, and a spring. The fixed jaw is vertically installed on the front wall of the crusher frame, while the movable jaw is suspended on the eccentric shaft. The toggle plate is located between the movable jaw and the rear wall of the frame, and the spring is used to maintain the proper tension and position of the components.
2. Power Transmission
The crusher is powered by an electric motor. The motor's power is transmitted to the eccentric shaft through a V - belt or a coupling. As the motor rotates, it drives the eccentric shaft to rotate at a certain speed.
3. Crushing Process
Compression and Impact
When the eccentric shaft rotates, it causes the movable jaw to perform a complex motion. The movable jaw moves towards and away from the fixed jaw in a periodic manner. During the forward movement of the movable jaw towards the fixed jaw, the materials placed between the two jaws are subjected to a combination of compression and impact forces. The compression force squeezes the materials, while the impact force breaks them into smaller pieces.
Crushing Chamber
The space between the fixed jaw and the movable jaw forms the crushing chamber. As the materials enter the crushing chamber from the top - side feed opening, they are gradually crushed as they move downwards through the chamber. The shape of the crushing chamber is designed to ensure that the materials are crushed multiple times as they pass through, achieving a high - efficiency crushing process.
Discharge
After the materials are crushed to the desired size, they fall out from the bottom of the crushing chamber under the influence of gravity. The size of the discharge opening can be adjusted by changing the position of the toggle plate or using a shim adjustment mechanism. This allows operators to control the particle size of the discharged materials according to specific production requirements.
4. Safety and Protection
The GC series jaw crusher is also equipped with safety features. For example, the toggle plate is designed to be a sacrificial part. In case of an overload or when a large un - crushable object enters the crushing chamber, the toggle plate will break first, protecting the more expensive components of the crusher, such as the eccentric shaft and the jaws, from damage.
In summary, the GC series jaw crusher uses power transmission to drive the movement of the movable jaw, applies compression and impact forces to crush materials in the crushing chamber, and allows for the adjustment of the discharge particle size. It also has safety features to protect the equipment from damage during abnormal operation.
