Working principle
A jaw crusher is a primary crushing machine used in various industries such as mining, quarrying, and construction. It works on the principle of compression, where the material is crushed between a fixed jaw and a movable jaw.
The material to be crushed is fed into the top of the crusher chamber. As the movable jaw moves towards the fixed jaw, the material is crushed between the two jaws. The crushing action occurs when the material is squeezed and compressed between the jaws.
The crushed material is discharged through the bottom of the crusher chamber, where it can be further processed or collected.
Our jaw crushers are equipped with an adjustment mechanism that allows the setting of the gap between the jaws to be adjusted to control the size of the crushed material.
Contamination-free crushing
The jaw plates are typically made of materials that are chemically inert and resistant to abrasion, such as stainless steel, tungsten carbide, zirconia or different types of materials this is depending on the sample that is being processed. These materials ensure that no contaminants are introduced into the crushed material during the crushing process. This is particularly important in industries such as pharmaceuticals, food processing, and environmental analysis.
Accessories and consumables
Jaw Plates
Jaw plates are the main crushing surfaces in a jaw crusher. They are fixed to the frame of the crusher and form the crushing chamber along with the movable jaw.
Jaw plates come in pairs, with one fixed jaw plate and one movable jaw plate. The material to be crushed is fed between the two jaw plates and crushed as the movable jaw moves towards the fixed jaw.
Jaw plates are typically made of high manganese steel or other wear-resistant materials to withstand the high impact and abrasion encountered during crushing operations.
They are designed to be easily replaceable when worn out.
Side Liners:
Side liners are protective components installed on the sides of the crushing chamber in a jaw crusher. They help to protect the crusher frame and provide additional wear protection for the jaw plates. Side liners are typically made of wear-resistant materials such as manganese steel, chromium steel, or composite materials. Side liners can be bolted or welded to the crusher frame, depending on the design of the crusher. They are designed to be easily replaceable when worn out to prolong the service life of the crusher.
Infeed Hopper:
The infeed hopper is a funnel-shaped container located at the top of the jaw crusher, where the material to be crushed is fed into the crushing chamber. The infeed hopper directs the material into the crushing chamber and helps to regulate the flow of material into the crusher. Infeed hoppers are typically equipped with a grizzly or a vibrating feeder to remove oversize material and prevent it from entering the crusher. They may also feature a level sensor or indicator to monitor the level of material in the hopper and prevent overloading of the crusher.
Collector:
The collector, also known as the discharge chute or discharge conveyor, is located at the bottom of the jaw crusher and collects the crushed material as it exits the crushing chamber. The collector directs the crushed material onto a conveyor belt or into a stockpile for further processing or transport. Collectors are typically equipped with a wear-resistant lining to withstand the impact and abrasion of the crushed material. They may also feature adjustable discharge openings or skirts to control the flow of material and prevent spillage.Proper maintenance and replacement of wear parts such as jaw plates and side liners are essential to maximize the performance and longevity of the crusher.
LMC200D Jaw Crusher with High volume collector
A custom collector can be designed to meet the specific requirements and constraints of the application.
This allows for optimal integration with the crusher and other downstream equipment, maximizing efficiency and productivity.
By customizing the collector design, it's possible to achieve optimized material flow from the crusher to the downstream processing or storage facilities.
This minimizes material spillage, reduces the risk of blockages, and ensures smooth operation of the entire crushing circuit.
A custom collector can be fabricated from wear-resistant materials and incorporate features such as liners, baffles, and deflectors to enhance wear resistance.
This helps prolong the service life of the collector and reduces maintenance requirements.
Custom collectors can be designed with safety features such as access doors, guardrails, and emergency stops to ensure safe operation and maintenance.
This helps minimize the risk of accidents and injuries in the workplace.
By optimizing material flow and wear resistance, a custom collector can help reduce downtime associated with maintenance, repairs, and cleaning. This improves overall equipment availability and uptime, leading to higher productivity and lower operating costs.
A custom collector can be designed to accommodate specific discharge options, such as adjustable discharge openings, discharge chutes, or discharge conveyors. This provides flexibility in the handling and disposal of crushed material, allowing for customization based on site-specific requirements.
A custom collector can contribute to improved product quality by minimizing material contamination, segregation, and degradation during discharge. This is particularly important in applications where product purity and consistency are critical, such as in pharmaceutical, food processing, and aggregate industries.
Jaw Crusher LMC200VD (vertical door)
A jaw crusher with vertical access to the jaw plates typically refers to a specific design feature where the jaws can be accessed vertically for maintenance or replacement purposes.
This design variation aims to simplify the maintenance process and improve accessibility to the jaw plates, which are critical components responsible for crushing the material.
In this design, the traditional horizontal access for accessing the jaw plates is modified to allow vertical access. This could involve incorporating hinges or other mechanisms to open the crusher vertically.
The vertical access to the jaw plates enables easier maintenance and replacement of the jaw plates when they become worn out or damaged.
Instead of accessing the jaws from the side or underneath the crusher, maintenance personnel can access them from above.
Safety features are incorporated to ensure safe access to the jaw plates. This includes safety locks or interlocks to prevent accidental opening while the crusher is in operation.
Vertical access to the jaw plates improves accessibility for maintenance tasks, reducing downtime and ensuring that maintenance procedures can be performed efficiently.
Jaw crushers with vertical access to the jaw plates are commonly used in industries such as mining, quarrying, construction, and recycling, where frequent maintenance and replacement of wear parts are necessary to maintain optimal performance.
While not all jaw crushers have this specific design feature, it can be a valuable addition for applications where accessibility and ease of maintenance are priorities.
