Product Introduction

In the field of stone processing, marble has become a preferred material for architectural decoration and artistic carving due to its unique textures and delicate texture. However, marble's characteristics of high hardness and brittleness impose strict requirements on the precision and stability of crushing equipment. The crawler mobile marble crusher, specially designed for medium-to-high hardness stones like marble, takes the crawler-type mobile chassis as its core and integrates precise crushing technology and intelligent control systems. It achieves flexible production throughout the entire process from large rough blocks to finished aggregates, redefining the standards of efficiency and precision in stone crushing.

Crawler chassis

Adopting a military-grade crawler transmission system, the track chain is made of high-strength manganese steel with a surface quenching treatment, which enhances wear resistance by 3 times. Equipped with a hydraulic suspension system, it can easily traverse complex terrains such as gravel-strewn mining roads and muddy wetlands, with a climbing angle of up to 30°. It can still operate stably in plateau mining areas above 4,000 meters above sea level. Compared with tire-type equipment, the crawler chassis improves mobility reliability by 50% in extreme environments, completely solving the dilemma of traditional equipment being "able to enter but unable to move".

Screening and circulation system

Equipped with a 4-layer vibrating screen, the screen mesh is made of a polyurethane + metal composite structure, achieving a screening efficiency of 95%. It can simultaneously produce three specifications of products: 0-5mm manufactured sand, 5-16mm crushed stone, and 16-31.5mm coarse aggregates. Unqualified materials are automatically returned to the crusher through a high-inclination return belt (inclination ≤35°), forming a closed-loop crushing process. This increases the comprehensive utilization rate of granite to 98%, reducing resource waste.

Environmental Pioneer

Three-Level Dust Control System

Source Dust Suppression: The feeding port is equipped with an atomizing spray device (atomized particle size ≤50μm), achieving a dust suppression rate of 70%.

Process Dust Reduction: The crushing cavity adopts a labyrinth seal + negative pressure dust collection system, with a dust collection efficiency of 95%.

Terminal Purification: Standard pulse bag dust collector (filtration accuracy ≤1μm) is equipped, with emission concentration <20mg/m³, superior to the national standard (80mg/m³).

Noise Reduction and Vibration Damping Technology

Soundproof Enclosure: Adopts a "double-layer steel plate + soundproof cotton" structure, reducing noise by 25dB, with equipment operation noise <85dB.

Vibration Damping Pad: Rubber vibration damping pads are installed at the connection between the crawler chassis and the main machine, reducing vibration amplitude by 60% and minimizing impact on the surrounding geology.

Resource Recycling Utilization

Scrap Steel Recovery: The equipment is equipped with an integrated iron separator (magnetic flux ≥1.2T), which can separate metal impurities in granite with a recovery rate of 98%.

Wastewater Treatment: A optional sewage circulation system can be configured to reuse wastewater from equipment cleaning after sedimentation and filtration, achieving a water resource utilization rate of 85%.
