Against the backdrop of the diversified advancement of infrastructure projects in Sri Lanka, there has been an increasing number of small and medium-sized projects such as highway reconstruction, rural road hardening, urban renewal supporting projects, and small-scale mineral development. These projects generally feature "scattered operation points, limited site space, diverse raw material types, and precise finished product requirements." Traditional fixed crushing equipment has a long deployment cycle and is inconvenient to transfer, while small mobile equipment suffers from insufficient capacity and unstable discharge quality, making it difficult to adapt to flexible and variable operation needs. Targeting this, Shanghai Dongmeng Road & Bridge Machinery Co., Ltd. has specially developed a tire-type mobile crushing plant, which takes "flexible combination, precise material discharge, and convenient transition" as its core advantages. Integrating full-process functions including feeding, crushing, screening, and conveying, it has become a "flexible rock-crushing tool" for small and medium-sized infrastructure and resource development projects in Sri Lanka, providing efficient and precise stone supply solutions for various projects.

It can flexibly switch configurations according to raw material characteristics (hard rock, soft rock, construction solid waste, etc.) and finished product requirements (cushion material, aggregate, sand-making raw material, etc.) without additional equipment, significantly reducing initial project investment;
• Rapid Transition for Efficient Adaptation: Adopts a high-strength tire chassis with a traction device, which can be quickly transported to different operation points by ordinary trailers. The transition process does not require complex disassembly and hoisting, adapting to scattered operation scenarios such as rural roads, suburban areas, and small mines. The deployment of operation point switching can be completed in only a few hours;
• Compact Layout Adapts to Narrow Sites: The equipment structure is highly integrated with a small floor area, which can be flexibly deployed in space-constrained areas such as rural roadsides, urban demolition sites, and small quarries. It does not require large-scale site leveling, reduces site reconstruction costs, and minimizes interference to the surrounding environment.

II. Precise Material Discharge: Laying a Solid Foundation for Project Quality

Small and medium-sized infrastructure projects also have strict requirements for the accuracy of stone particle shape and gradation, which are directly related to core indicators such as road strength and building structure stability. Through process optimization and intelligent control, Dongmeng's tire-type mobile crushing plant achieves precise output of finished stones.

• Classified Crushing to Optimize Particle Shape: Adopts a targeted crushing process design. The primary crushing link realizes preliminary shaping of raw materials, and the secondary and tertiary crushing links further optimize the particle shape through the principle of laminated crushing. The finished stones have a high proportion of cubic particles, with the content of needle-like and flake-like particles less than 10%, fully meeting the material standards for rural highways, small buildings, municipal engineering and other projects;
• Intelligent Screening for Precise Classification: Integrates an efficient vibrating screening system, with screen mesh aperture that can be accurately adjusted according to finished product specifications (0-5mm, 5-10mm, 10-20mm, etc.). It has high screening efficiency and good classification effect, and can quickly separate qualified finished products of different particle sizes, avoiding mixing of finished materials and ensuring consistency of feeding quality;
• Adjustable Parameters to Adapt to Needs: Equipped with a simple intelligent control system, operators can real-time adjust parameters such as feeding speed and crushing gap according to actual needs, flexibly adapting to the differentiated requirements of different projects for finished product particle sizes. It can accurately produce everything from road cushion materials to fine concrete aggregates without secondary processing.
