250TPH Three Combination Mobile Crushing Station for Granite Aggregate in South Africa

Project Background

Southern Cross Quarrying (Pty) Ltd., a South African quarrying company based in Gauteng Province, secured a contract to supply crushed granite aggregate for a national road upgrading project in Limpopo Province, approximately 400 kilometres from their main quarry. Rather than establishing a fixed plant at the remote site, the company's operations manager, Mr. Pieter van der Berg, decided to invest in a mobile crushing station that could be deployed to the Limpopo site and subsequently relocated to other projects. He began searching for mobile crushing plant suppliers on Google and LinkedIn in late 2022, and found Xianglong Machinery's website and LinkedIn company page. He sent a direct message via LinkedIn and received a prompt response from XLM's Africa sales engineer, Ms. Jenny Zhao.

Channel Communication and Needs Assessment

Ms. Zhao arranged a WhatsApp video consultation with Mr. van der Berg and XLM's mobile plant specialist, Mr. Jason Huang. The granite at the Limpopo site had a compressive strength of 180-220 MPa and a feed size of up to 600 mm from blasting. The required output was 0-5 mm, 5-13 mm, and 13-37 mm crushed granite at 250TPH for road base and wearing course applications, meeting South African National Roads Agency (SANRAL) specifications.

Technical Solution and Engineering Alignment

Jason proposed a Three Combination Mobile Crushing Station -- a wheel-mounted, three-module plant comprising a primary module with a ZSW Vibrating Feeder and PE-1200x1500 Jaw Crusher, a secondary module with an HP300 Multi-cylinder Hydraulic Cone Crusher, and a screening module with a 3YK2460 Circular Vibrating Screen, all connected by portable Belt Conveyors. The modular design allowed rapid assembly and disassembly for relocation, with each module transportable on standard South African road-legal trailers.

Technical discussions proceeded over four weeks via WhatsApp and email. Jason provided detailed transport dimension drawings confirming compliance with South African road transport regulations (maximum width 3.0m, height 4.2m for provincial roads), a plant assembly time estimate of 5 working days, and SANRAL-compliant product gradation data from similar granite crushing applications. For South Africa's Highveld plateau conditions (altitude 1,500-1,800m, high UV index, diurnal temperature swings of 15-25°C), the mobile plant was specified with: UV-resistant hydraulic hoses and rubber components (rated for 10,000+ hours UV exposure), wide-temperature-range hydraulic oil (operating range -10°C to 50°C), electrical components with enhanced insulation for large temperature variations, and motor bearings pre-lubricated for high-altitude operation. The contract was signed in January 2023, with a delivery period of 85 days.

Delivery, Installation, and Commissioning

Equipment was shipped from Qingdao to Durban port and transported by road to the Limpopo site. XLM's commissioning engineer, Mr. Jason Huang, was on-site for 14 days to oversee assembly and commissioning. The Three Combination Mobile Crushing Station achieved 260TPH of on-spec crushed granite during the acceptance test.

Results and Client Feedback

Within four weeks of commissioning, Southern Cross Quarrying was meeting its aggregate supply schedule for the Limpopo road project. The plant was subsequently relocated to a new project in the North West Province in under six working days -- demonstrating the mobility advantage that had justified the investment. Mr. Pieter van der Berg stated: "XLM's Three Combination Mobile Crushing Station is a game-changer for our business. The ability to move the plant quickly between projects has opened up contracting opportunities we could never have pursued with a fixed plant. We are planning to order a second mobile station from XLM for our growing project pipeline."
