LMC50 features in the compact design, easy operation and the high final fineness of sample (d90 < 0.5mm ) . The sample enters the grinding chamber via the anti-splashing hopper. The crushing is proceeded inside the wedge-shaped shaft space between two jaw plates. one jaw plate is fixed, while the other jaw plate is driven by a bent axle to perform oval movement with the continuous rotation of the motor. The sample is crushed due to extrusion caused by constant movements of the jaw plate and moves downward under the effect of gravity. In case the grain size of the sample is less than the lower opening gap of jaw plates, it will fall to the drawer receiver at the lower part of the machine.

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.

LMC50 Jaw Crusher FAQ (Frequently Asked Questions)

The LMC50 is designed for rapid size reduction of hard, brittle and dry materials such as rocks, minerals, ceramics, glass, slag and similar laboratory samples. Material suitability depends on hardness, brittleness and moisture content.

With the correct gap setting and sample characteristics, the LMC50 can achieve a typical end fineness of d90 < 0.5 mm. Final size depends on feed size, material hardness and the selected jaw gap.

The LMC50 has a jaw inlet of 50 × 40 mm and is suitable for a maximum feed size of 40 mm (recommended). Oversized pieces should be pre-broken to protect wear parts and maintain throughput.

The jaw gap is steplessly adjustable with a small knob. A zero-point reference allows you to set the gap precisely and repeatably, helping you achieve consistent results across different batches.

Jaw plates and wear parts can be supplied in multiple materials depending on your contamination and wear requirements, including hardened steel, manganese steel, stainless steel, and tungsten carbide options (availability depends on configuration).

The LMC50 is built for fast access and easy cleaning. Open the chamber, remove loose residues, and brush or wipe the jaw area. For trace-analysis workflows, you can use dedicated wear-part materials and cleaning procedures to reduce cross-contamination.
