Jaw Crusher and Impact Crusher Production Line for Granite and Limestone

Mine Stone Crushing Production Line Project Overview

This 600 t/h jaw and impact crusher mining crushing production line, with a peak capacity of 800 t/h and a total installed power of approximately 1,115 kW, is specifically designed for the harsh operating conditions of high-hardness ore in the Middle East and North Africa. It is capable of processing medium- to high-hardness ores such as granite and limestone. The entire line is CE certified to meet overseas import compliance requirements. The equipment operates in temperatures ranging from -20°C to 55°C, with low-temperature impact toughness of no less than 35 J/cm², making it suitable for the high temperatures of the Middle East and the significant day-night temperature fluctuations in Africa.

Key Challenges: Low crushing efficiency and rapid wear of high-hardness raw ore; frequent equipment failures and downtime affecting delivery; high rejection rates due to excessive flakiness in finished products; slow procurement of spare parts overseas and delayed after-sales response.

Solution Highlights: NM600 wear-resistant steel plates (570-600 HBW) offer 10 times the wear resistance of ordinary steel, extending overall equipment lifespan by 3.5 times and reducing annual maintenance costs by 25%; Predictive maintenance system increases mean time between failures (MTBF) by 20% and reduces downtime by 50%; finished product flakiness below 10% ensures a 99% order fulfillment rate; standard modular configuration reduces costs by 15%-20% compared to custom solutions and accelerates delivery by 30 days; remote data monitoring + quarterly technical follow-ups achieve a fault resolution rate of no less than 98% and equipment availability exceeding 85%.

Mine Stone Crushing Production Line Process Flow

Raw material unloading → DLZGC1538 vibrating feeder for uniform feeding → DLEV160 jaw crusher for primary crushing → DLHCS1523 impact crusher for secondary and tertiary crushing → circular vibrating screen for classification → oversized material returned to the circuit → qualified products sent to the finished product pile. NM600 wear-resistant components cover core high-wear areas such as jaw plates, hammer plates, and liners, making them suitable for long-term, high-load crushing of granite. The predictive maintenance system monitors equipment status in real time and provides early warnings, while energy-saving design across the entire line reduces operational pressure caused by high electricity costs overseas.

Mine Stone Crushing Production Line Project Case Study

Granite Aggregate Technological Upgrade Project for a Major Mining Company in an African Country: The original standard equipment was unsuitable for high-hardness granite, resulting in monthly replacement part costs exceeding $5,000, average daily downtime exceeding 4 hours, an order fulfillment rate of only 65%, and a high order rejection rate due to flake and needle content exceeding 18%.

Post-upgrade: Production capacity increased from 420 t/h to a stable 600 t/h with a peak of 800 t/h, representing a 42.9% increase; average daily downtime decreased from 4.2 hours to 1.8 hours, a 57% reduction; Monthly maintenance costs dropped from $5,200 to $3,900 (a 25% reduction); wear part lifespan increased by 3.5 times; flakiness decreased from 18.5% to 9.2% with zero order rejections, and the delivery rate rose from 65% to 99%. The client became the preferred aggregate supplier for local highway infrastructure projects, with annual order volume increasing by 60%.

Mine Stone Crushing Production Line FAQ

1. Is this 600 t/h crushing line suitable for processing high-hardness granite in Africa?

It is fully compatible. The jaw crusher and impact crusher combination is specifically designed for medium-to-high-hardness ores. Low Downtime Stone Crushing Production Line Core components utilize NM600 wear-resistant steel plates, which are 10 times more wear-resistant than ordinary steel. It can stably process 600 t/h of granite and limestone, with a flakiness and elongation rate below 10%, meeting local infrastructure quality standards.

2. Can you provide full-process turnkey services for overseas clients?

We offer one-stop turnkey services covering the entire process from survey and design, equipment manufacturing, to installation, commissioning, and technical training. We provide 24-hour fault response with on-site repairs within 72 hours, a 12-month warranty on core components, and maintain a stock of spare parts overseas to address the pain points of slow procurement and delayed after-sales service.

3. What are the delivery timeline and approximate investment costs?

Standard modular configurations reduce costs by 15%–20% compared to custom solutions. The initial investment is approximately 2 million RMB, and the delivery timeline is shortened by 30 days compared to traditional solutions. This enables rapid production start-up and cash flow recovery, addressing the challenges of tight schedules and urgent production needs in overseas projects.
