350TPH TF350 Track-mounted Mobile Impact Crusher for Limestone Quarrying in Brazil

Project Background

Pedreira Brasil Ltda., a Brazilian quarrying company based in Minas Gerais State, secured a contract to supply crushed limestone aggregate for a large highway construction project in a remote area of the Cerrado region, approximately 500 kilometres from their main quarry. The temporary nature of the contract and the remote location made a track-mounted mobile crushing solution the most cost-effective option. The company's CEO, Mr. Fernando Oliveira, began searching for track-mounted mobile impact crusher suppliers on Google in late 2022 and found Xianglong Machinery's website, which featured detailed product pages for theTF350 Track-mounted Mobile Impact Crusher. He also found XLM's Facebook business page and sent a message through the platform.

Channel Communication and Needs Assessment

XLM's Latin America sales engineer, Mr. Kevin Liu, responded to the Facebook message within 24 hours and established ongoing communication via WhatsApp and email. Mr. Oliveira described the limestone characteristics: a Mohs hardness of 3-4, a maximum feed size of 600 mm from blasting, and a target output of 0-25 mm crushed limestone at 350TPH for road base applications. The remote Cerrado site had limited infrastructure, making the track-mounted plant's self-propelled mobility and diesel-electric power pack essential features.

Technical Solution and Engineering Alignment

XLM's mobile plant specialist, Mr. Jason Huang, recommended the TF350 Track-mounted Mobile Impact Crusher configured with a Impact Crusher mounted on a self-propelled crawler chassis with a diesel-electric power pack. The PF-1520 was selected for its high throughput capacity, high reduction ratio, and excellent product shape for limestone -- producing well-shaped cubical aggregates suitable for road base and asphalt applications. The crawler chassis allowed the plant to move between quarry faces without dismantling, and the diesel-electric system eliminated the need for grid power connection at the remote site.

Technical discussions proceeded over three weeks via WhatsApp and email. Jason provided detailed performance specifications, fuel consumption data for the diesel-electric system (estimated 45-55 liters per hour at full load), and a comparison with a fixed plant alternative showing the mobile option's lower total project cost for a 24-month contract duration. For Brazil's Cerrado tropical savanna climate with intense wet season rainfall (October-March), the track-mounted plant was specified with: IP67-rated electrical components throughout for high-humidity and direct water exposure protection, elevated chassis design with 450mm ground clearance for muddy quarry conditions, tropical anti-corrosion coating on all structural components, and reinforced weatherproof enclosures for the diesel-electric power pack. The contract was signed in January 2023, with a delivery period of 90 days.

Delivery, Installation, and Commissioning

The track-mounted crusher was shipped from Qingdao to Santos port and transported by heavy-lift transport to the Cerrado site. XLM dispatched commissioning engineer Mr. Jason Huang to Brazil for a 12-day on-site commissioning and operator training programme. The plant achieved 365TPH during the acceptance test, exceeding the guaranteed capacity.

Results and Client Feedback

Within three weeks of commissioning, the TF350 Track-mounted Mobile Impact Crusher was operating reliably at the remote Cerrado site, meeting the highway project's aggregate supply schedule. The plant was subsequently moved to a second project area within the same contract, demonstrating its mobility advantage. Mr. Fernando Oliveira stated: "XLM's TF350 Track-mounted Mobile Impact Crusher has been the right tool for this project. The self-propelled crawler system has saved us enormous time and cost in plant relocation. The limestone product quality is excellent, and our client is very satisfied. We are planning to purchase a second track-mounted crusher from XLM for our next major project."
