Limestone Crawler Mobile Crusher

Aiming at the characteristics of limestone with high mud content and easy adhesion, the crushing chamber adopts an inverted cone structure + anti-stick coating design.

Optimized inverted cone angle: The cone angle of the crushing chamber is expanded to 45°, an increase of 15° compared with traditional designs, which effectively reduces material retention time and prevents mud from sticking.

Nano-coating treatment: The chamber wall surface is sprayed with a Teflon anti-stick coating, reducing the surface friction coefficient to 0.05. This increases the passing rate of clay-like materials by 40% and reduces the frequency of shutdown for cleaning.

Dynamic adjustment of crushing strategies based on the compressive strength of limestone (60-100MPa):

High-silica limestone (Si content >15%):Activate the "jaw primary crushing + cone secondary crushing" combination. Utilize the principle of laminating crushing to reduce wear on wear-resistant parts, extending the life of liners to 6,000 hours.

Low-calcium limestone (CaO content <50%):Switch to the "impact crushing" mode. Achieve particle size homogenization through impact crushing, increasing the proportion of 0-5mm manufactured sand in the finished product to 35%, meeting the production requirements of dry mortar.

Built-in metal detection + automatic iron removal device:

Pulse-type metal sensor: Detection accuracy reaches φ5mm iron parts, with a response time of <0.5 seconds.

Hydraulic iron removal mechanism: When iron parts are detected, the bottom of the crushing chamber automatically opens an iron discharge port, completing impurity removal within 10 seconds. This avoids machine jams and equipment damage while ensuring the purity of limestone (iron content ≤0.01%).

Ultra-wide crawler design: The crawler width is increased to 900mm, and the ground contact pressure is as low as 0.04MPa. In muddy limestone mine sites with a moisture content of >25%, the risk of machine sinking is reduced by 80%.

Anti-slip control system: Real-time monitoring of crawler speed differences through torque sensors. When one-side crawler slips, the other-side crawler automatically increases driving force by 20% to ensure stable operation of the equipment on 15° wet and slippery slopes.

Modular highway transportation: The detachable screening module design compresses the overall width to 3.5 meters during relocation, meeting highway transportation width restrictions. Cross-province relocation can be completed within 12 hours.

Self-propelled mode: Equipped with a low-speed traveling motor, short-distance movement within mining areas does not require a tractor. The autonomous movement speed reaches 3 km/h, flexibly responding to the needs of multiple work points.
