Project Overview
The Lvdaeyuan Building Materials Co., Ltd. Project is one of the largest single-line aggregate production facilities in southwestern China. Located in Chongqing municipality, this 6,000 TPH plant processes limestone for the region massive infrastructure and urbanization programs.
项目范围
WSHT designed and supplied a three-stage crushing and screening plant optimized for Chongqing limestone (compressive strength 80-120 MPa, Bond Work Index 11.5 kWh/t). The plant operates 24/7 with 92% availability.
Process Flow
Primary Crushing: A C200 jaw crusher (2000×1500 mm) processes ROM limestone (P80 = 1,500 mm) at 1,000-1,500 t/h. The crusher features hydraulic toggle adjustment for CSS optimization.
Secondary Crushing: 4× HP800 cone crushers (standard cavity) operate in parallel at 300-500 t/h each, reducing product to −60 mm. Load-sharing control maintains equal throughput across all four units.
Tertiary Crushing: 2× HP500 cone crushers (short-head cavity) produce −25 mm final product at 250-400 t/h each. Closed-circuit with 2× 4YK-3072 screens.
Screening & Stockpile: 4× 4YK-3072 screens classify product into 5 sizes. Radial stackers create 50,000-tonne live stockpiles per product size.
