Limestone Fine-Grade Aggregate Production Line
Limestone Production Line Project Overview
Designed to meet the demand for the co-production of limestone aggregate and dry powder, this dual-line production line features a configuration of 2×ZGC2050 feeders + 2×PCZ1820 heavy-duty hammer crushers + 4×PC1220 shaping machines + 16 circular vibrating screens. It produces four types of finished products: 1–3 mm, 1–2 mm, and 0–0.5 mm aggregates, as well as dry powder. Key Highlights: The dual-line parallel design enhances system redundancy and ensures production capacity; the combination of primary crushing by heavy-duty hammer crushers and closed-circuit secondary crushing by shaping machines delivers excellent particle shape and precise gradation; the 3YKZ3070 + 2YKZ3070 multi-layer screening system enables fine classification, with the classifier producing qualified dry powder, achieving co-production of aggregates and powder on a single line.
Limestone Production Line Process Flow
Raw limestone - 2×ZGC2050 vibrating feeders - 2×PCZ1820 heavy-duty hammer crushers for primary crushing - Main belt conveyor - 4×3YKZ3070 circular vibrating screens for grading (outputs 1-3mm and 1-2mm finished products) - >3mm returned to 4×PC1220 shaping crushers for re-crushing - returned to main belt for re-screening - 4×3YKZ3070 circular vibrating screens for grading (outputs 0-0.5mm finished product) - remaining material fed into classifier - dry powder finished product stored in silos
Limestone Production Line EPC Services
Full-chain EPC Turnkey: Site survey and equipment selection - Customized equipment (core equipment such as DLKPC/DLHGC/DLHPT/DLZSJ/DLVF + fully enclosed box-type belt conveyors + circular vibrating screens + classifiers + prefabricated walkways) - Installation and commissioning - Operation and maintenance management - Direct supply of wear-resistant spare parts. Configurations are customized based on output specifications, production capacity, and dry powder fineness requirements.
Limestone Production Line Project Case Studies
Tashkent Limestone Aggregate Project, Uzbekistan: Dual-line parallel configuration featuring a PCZ1820 heavy hammer crusher and a PC1220 shaping machine in a closed-circuit system, producing four product categories: 1-3mm, 1-2mm, 0-0.5mm aggregates, and dry powder. 16 circular vibrating screens for fine grading. Aggregates are supplied to local road construction projects, while dry powder is supplied to cement mixing plants. Customer feedback indicates a significant improvement in the accuracy of finished product gradation compared to the original line, and the closed-circuit shaping process has reduced the oversize return rate by 35%.
Limestone Production Line FAQ
Q1: What is the difference between a dual-line parallel configuration and a single-line high-capacity solution?
Dual-line parallel operation allows each line to run independently; when one line is under maintenance, the other continues production. Limestone Hammer Crusher Shaping Production Line This provides high system redundancy and minimizes downtime losses, while also enabling single-line operation as needed to reduce energy consumption during low-load periods.
Q2: How does closed-circuit re-crushing with a shaping machine reduce the oversize return rate?
The PC1220 shaping machine is designed for secondary crushing and shaping of oversize material from the screen. Integrated Limestone Aggregate and Dry Powder Production The closed-circuit cycle ensures that oversize material is repeatedly processed until it meets specifications, reducing the return rate by more than 35% compared to open-circuit solutions.
Q3: How is the quality of both aggregate and dry powder ensured in a combined production process?
Multi-layer circular vibrating screens provide precise diversion, keeping the aggregate and powder pathways separate. Fine Grade Aggregate Processing Solution The airflow classification of the classifier allows for controllable dry powder fineness, ensuring that the two product types do not interfere with each other.
Q4: Can the output specifications (1-3mm, 1-2mm, 0-0.5mm) be adjusted?
Both the number of screen layers and mesh sizes can be customized to meet project requirements. The gradation combination can be adjusted simply by replacing the screens, without any modifications to the main equipment.
