The LMFC250 Fine Crusher is designed for batch wise and continuous pre-crushing of middle hard, hard brittle and tough materials for the following fine grinding.
The Model LMFC250 Fine Crusher is used by laboratories and processing companies to crush solid materials such as rocks or soil and ores.
The material to be processed falls into the crushing chamber of the LMFC250 via a guide chute and is crushed by crushing action of a static and a dynamic jaw plate until it passes the preselected gap of the crusher.

Jaw Crusher 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
Contamination-free crushing with a jaw crusher refers to the process of crushing materials in such a way that ensures minimal contamination from external sources.
This is particularly important in industries such as pharmaceuticals, food processing, and environmental analysis, where sample purity is critical.
In a contamination-free design, the jaw plates are 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.
By incorporating jaw plates and side liners made of chemically inert and abrasion-resistant materials, contamination-free jaw crushers offer a reliable and efficient solution for achieving contamination-free crushing in sensitive applications.
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.
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 equipped with a wear-resistant lining to withstand the impact and abrasion of the crushed material.
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.
LMFC250 Fine Crusher with vibratory feeder and Sieving street
Combining a jaw crusher with a vibratory feeder and sieving street can create an integrated system for the efficient processing and screening of crushed materials.
A vibratory feeder and sieving street is a screening device used to separate particles based on size or other properties.
It consists of a screening surface made of wire mesh or perforated plate that vibrates in a linear motion, allowing particles to pass through or be retained based on their size.
The jaw crusher is used to crush the bulk material into smaller particles of a uniform size range.
The crushed material is then fed onto the linear vibrating screen filter sieve for screening.
The linear vibrating screen filter sieve efficiently separates the crushed material into different size fractions.
Oversized particles are retained on the screen surface and discharged at the end of the sieve, while properly sized particles pass through the sieve mesh and are collected in the undersize fraction.
By combining a jaw crusher with a linear vibrating screen filter sieve, laboratories and industrial facilities can perform quality control and assurance checks on crushed materials.
The screening process ensures that only properly sized particles are retained for further processing or analysis, while oversized particles are rejected.
The combination setup enables efficient material handling and processing. It eliminates the need for manual sorting or screening of crushed materials, saving time and labor costs.
The combination of a jaw crusher and a linear vibrating screen filter sieve is versatile and can be used for various types of materials, including rocks, ores, minerals, aggregates, and other solid materials. This versatility makes it suitable for a wide range of applications in industries such as mining, quarrying, construction, and recycling.
Depending on the setup and configuration, the combination system can be integrated with automation and control systems for seamless operation. This integration enhances productivity, reduces downtime, and improves overall efficiency.
Fine Crusher custom infeed hoppers
Custom infeed hoppers for jaw crushers are designed to enhance the efficiency and adaptability of material processing operations.
These hoppers are tailored to accommodate specific material types, sizes, and volumes, ensuring optimal feeding and reducing the risk of blockages.
They can be constructed from durable materials to withstand heavy-duty use and abrasive conditions, with options for liners and wear-resistant coatings to prolong service life.
Additionally, custom infeed hoppers can include features such as adjustable flow controls, dust suppression systems, and integrated screens for pre-sorting material.
By streamlining the feeding process, custom infeed hoppers contribute to improved crusher performance, reduced downtime, and greater operational flexibility.
LMFC250 Fine Crusher project integration
In a sampling installation, the jaw crusher serves as the primary size reduction equipment, ensuring that the bulk material is crushed to a uniform and manageable size before further processing.
The crushed material can then be accurately divided using devices such as rotary sample dividers, ensuring that representative sub-samples are obtained for analysis.
The integration of a jaw crusher enhances the reliability and accuracy of the sampling process, making it
an essential component in various industries, including mining, mineral processing, environmental testing, and quality control. Visit our projects page to see all our custom build installations and solutions
