Equipment Introduction
The Crawler mobile cone crusher station is a high-end crushing equipment that integrates efficient crushing, intelligent control, and flexible mobility. It is specifically designed for sectors such as mining, construction aggregate processing, and solid waste treatment.
Adopting an integrated vehicle-mounted design, this equipment combines a high-performance hydraulic cone crusher, an intelligent feeding system, a vibrating screening device, and conveying equipment onto a movable chassis. It can be quickly deployed to job sites without the need for complex infrastructure. Boasting the characteristics of "high efficiency in secondary and tertiary crushing, excellent finished product particle shape, and strong adaptability to complex sites," it is mainly used for the secondary crushing of medium-hard to extra-hard materials.
This plant perfectly connects "primary crushing (e.g., track-mounted jaw crushers)" and "screening/sand making" processes. It is widely applied in scenarios including mining, high-value recycling of construction waste, high-quality aggregate production for infrastructure projects, and solid waste resource utilization, effectively addressing the crushing needs of "scattered job sites + high-hardness materials + high-quality finished products."
Equipment Applications
In the extraction of open-pit metal mines and non-metallic mines, the ore after primary crushing requires further secondary and tertiary crushing to meet the particle size requirements for mineral processing or sand making. The Crawler mobile cone crusher station can move with the mining face, eliminating the need for long-distance transportation of primary-crushed ore. Meanwhile, it ensures uniform particle shape of the finished product through "laminated crushing" and reduces over-crushing.
Application Details
Secondary & Tertiary Crushing for Metal Ores: Processes primary-crushed iron ore, copper ore, and gold ore, crushing the coarse ore of 50-200mm down to 10-50mm. This meets the "fine-grain feed" requirement for ball mill mineral processing and improves mineral processing recovery rates.
Secondary & Tertiary Crushing for Non-Metallic Ores: For materials such as granite, basalt, and quartzite, it crushes the primary-crushed materials of 30-300mm to 5-30mm. The finished product serves as raw material for manufactured sand or high-quality coarse aggregate for construction, with the content of needle-shaped and flaky particles ≤ 10% and continuous gradation.
II. High-Value Recycling of Construction Waste: Producer of High-Quality Recycled Aggregates
With the advancement of "zero-waste cities," construction waste needs to shift from "simple backfilling" to "high-value recycling," which requires recycled aggregates to have good particle shape, excellent gradation, and low impurity content. The Crawler mobile cone crusher station can perform secondary and tertiary crushing on construction waste that has undergone primary crushing, producing recycled aggregates that meet high-value requirements.
Application Details
Production of Recycled Concrete Aggregates: Processes concrete blocks (20-150mm) that have been primarily crushed by track-mounted jaw crushers, crushing them down to 5-25mm. Impurities are removed through subsequent screening, resulting in finished products with a mud content ≤ 2% and a crushing value ≤ 16%. These aggregates can directly replace natural sand in C30-C50 recycled concrete.
Production of Recycled Permeable Brick Aggregates: Targets brick-stone mixtures (30-200mm) after primary crushing, crushing them to 3-10mm. The "laminated crushing" principle of the cone crusher is utilized to reduce needle-shaped and flaky particles, resulting in finished aggregates with rounded particle shapes. These aggregates meet the molding requirements of permeable bricks for "high water permeability and high strength."
High-end infrastructure projects such as highways, railways, and bridges impose strict requirements on the "strength, particle shape, and gradation" of aggregates, and therefore require high-quality medium and fine aggregates. Crawler-mounted mobile cone crushing plants can move in tandem with project progress to process rock raw materials along the project route on-site. This eliminates the need for long-distance transportation of externally procured aggregates, ensuring both project schedule adherence and aggregate quality.
Application Scope
Production of High-Quality Aggregates for Highways/Railways: It processes basalt and diabase (Mohs hardness grade 7-8) obtained from mountain blasting along the project route, crushing the coarsely crushed rocks (30-250mm) into aggregates of 5-20mm. These aggregates are used as the surface layer aggregate for asphalt pavements or the concrete aggregate for high-speed railway track slabs. The crushing value of the finished product is ≤12%, which meets the requirements specified in the Technical Specifications for Construction of Highway Asphalt Pavements.
Production of Wear-Resistant Aggregates for Water Conservancy Projects: Concrete pouring for reservoirs and dams requires aggregates with erosion resistance and wear resistance. By using cone crushers to crush limestone or granite, aggregates of 10-30mm are produced. These aggregates feature high compactness and rough surfaces, ensuring strong bonding with cement paste and thereby enhancing the impermeability of concrete.
IV. Industrial Solid Waste Resource Utilization Sector: "Pretreatment Tool" for High-Hardness Solid Waste
High-hardness industrial solid wastes generated in industries such as metallurgy and building materials (e.g., steel slag, waste bricks from cement kilns, glass slag) have a Mohs hardness of grade 6-8. They require medium and fine crushing pretreatment first before further recovery of valuable components or conversion into recycled building materials. The crawler-type mobile cone crushing plant can enter solid waste stockpiling areas to flexibly complete crushing operations, reducing pollution caused by solid waste transportation.
Application Content
Pretreatment for Steel Slag Resource Utilization: It processes steel slag from iron and steel plants (single piece size: 50-200mm), crushing it to 10-50mm. Subsequently, iron particles are separated via a magnetic separator (recovery rate ≥85%), and the tailings are used to produce unburned bricks or roadbed fillers-realizing "reduction + resource utilization" of steel slag.
Recycling of Waste Bricks from Cement Kilns: It crushes waste refractory bricks from cement kilns (Mohs hardness grade 7) to 5-30mm, which are then reused as auxiliary materials for cement raw meal and mixed back into the kiln. This replaces part of natural ores, lowers cement production costs, and reduces the amount of solid waste sent to landfills.

Materials that should be avoided include: high-viscosity materials (e.g., wet clay, silt), overly soft and cohesive materials (e.g., gypsum, talc), and powdery/fine-grained materials (particle size < 50mm, no need for medium or fine crushing). Such materials are prone to causing equipment clogging or over-crushing, which prevents the cone crusher from exerting its advantage in "particle shape optimization."
