Working Principle of Mobile Crushing Equipment

The Zhongyu Dingli Mobile Crusher integrates a Stone Crusher, Sand Maker, Vibrating Screen and belt conveyor into a single unit, enabling one-stop operation from feeding and crushing to screening, sand making and classification. The product line includes Crawler Mobile Crusher and Wheel Mobile Crusher configurations, both designed for flexible deployment across mines, infrastructure projects and construction waste recycling sites. The Crawler series features a patented crawler chassis (CN202121149722.5) powered by a Cummins engine, with a maximum feed size of 600mm and a capacity range of 160-400t/h. The DLMC1512 model achieves a stable capacity of 250-400t/h, exceeding the industry average. The Wheel series provides cost-effective mobility for road, bridge and airport construction aggregate supply, as well as demolition site recycling. Both series support dry crushing technology, making them suitable for water-scarce regions, and comply with European, American and African environmental standards through patented low-noise and sealed operation design.

Project Overview

In global mining and infrastructure development, project sites are often scattered across remote or complex terrains where transporting raw materials to fixed crushing plants is costly and time-consuming. Conventional stationary production lines require lengthy civil engineering work, occupying large areas and taking months before operation begins. The Zhongyu Dingli Mobile Crusher addresses these pain points by bringing the crushing plant directly to the material source. With on-site crushing capability, transportation cost per ton of material is reduced by over 40%, and installation and commissioning can be completed in just 2 hours, saving approximately 2 months of infrastructure cycle compared to fixed production lines. The equipment handles a wide range of materials including granite, basalt, limestone, bluestone, pebble, dolomite and construction waste, making it the preferred crushing solution for overseas projects in more than 60 countries across South America, Africa and beyond.

Process Flow

Raw materials are fed into the hopper and uniformly conveyed to the primary Stone Crusher, where large rocks up to 600mm are reduced to intermediate size through jaw or hammer crushing. The crushed material then enters the high-efficiency Sand Maker for further fine crushing and shaping, producing high-quality manufactured sand with controlled particle geometry. The processed material is transferred to the multi-layer Vibrating Screen, which accurately classifies finished products into multiple specifications such as 0-10mm and 10-25mm, with a finished product qualification rate exceeding 95%. Oversized material is returned to the crusher for reprocessing, forming a closed-loop circuit that maximizes yield and minimizes waste. The entire workflow from feeding to final classification operates within a single integrated unit, requiring no additional production line construction and enabling immediate operation upon installation.

EPC Service Content

Zhongyu Dingli delivers full EPC turnkey services for Mobile Crusher projects worldwide. In the engineering design phase, the technical team conducts on-site surveys and customizes equipment configuration and crushing mode selection based on material characteristics, terrain conditions and capacity requirements. During manufacturing, all core modules including the Stone Crusher, Sand Maker, Vibrating Screen and conveyor system are produced in-house with strict quality control and wear-resistant component standards. For installation and commissioning, Zhongyu Dingli dispatches experienced engineers to the project site for rapid assembly, system calibration and operator training, ensuring the equipment reaches optimal performance within the 2-hour installation window. In the operations and maintenance phase, Zhongyu Dingli provides remote intelligent monitoring, scheduled maintenance plans and spare parts supply, supporting long-term stable operation across diverse global environments.

Project Cases and Data

In a hard rock processing project in Ecuador, the Crawler Mobile Crusher achieved a stable output of 150t/h, consistently meeting the aggregate demand for local road construction despite challenging material hardness. The equipment has been exported to more than 60 countries across South America, Africa and Southeast Asia, serving open-pit mines, highway construction, airport runway projects and urban construction waste recycling operations. The DLMC1512 Crawler model demonstrates a verified capacity of 250-400t/h, while the finished product qualification rate consistently exceeds 95% across various material types including granite, basalt and limestone. Compared to fixed production lines, Mobile Crusher projects save approximately 2 months of infrastructure construction time and reduce material transportation costs by over 40%, delivering measurable economic benefits for global contractors and mine operators.

FAQ

Q1: What materials can the Mobile Crusher process? The Mobile Crusher is designed to handle a comprehensive range of materials including hard rocks such as granite and basalt, medium-hard materials like limestone and bluestone, as well as pebble, dolomite, coal gangue, calcite, quartz stone, iron ore, barite, diabase, tuff, high calcium limestone and construction waste. The crushing mode can be quickly switched according to different material requirements, supporting both aggregate production and high-quality manufactured sand making.

Q2: How does the Crawler Mobile Crusher perform in complex terrain conditions? The Crawler Mobile Crusher adopts a patented crawler chassis powered by a high-performance Cummins engine, enabling flexible movement across mountainous areas, mining zones and urban construction sites. It eliminates the need for raw material transportation by realizing on-site crushing directly at the operation point, reducing transportation cost per ton by more than 40%. The compact transportation size and quick-disassembly design allow installation and commissioning to be completed in just 2 hours.

Q3: Does the Mobile Crusher meet international environmental standards? Yes. The Mobile Crusher relies on patented low-noise and environmental protection technology, featuring a noise-reducing shell and sealed operation design. Both dust emission and noise levels comply with European, American and African environmental standards, enabling operation in urban peripheries and areas with strict environmental requirements without additional dust removal equipment. The dry crushing technology also makes it suitable for water-scarce working conditions, further expanding its application scope across global projects.
