300T/H Construction Waste Crushing Machine Production Line

This project’s client is a state-owned enterprise aiming to improve the local resource utilization and promote the application of high-quality sand and gravel aggregates. The client has signed an EPC turnkey contract with Liming Heavy Industry to jointly create an intelligent and environmentally friendly solid waste recycling and reuse project.

Liming Heavy Industry provides customized solutions, intelligent equipment, and refined services. With rich experience and close cooperation with the client and design institute, Liming Heavy Industry quickly responds to customer needs during the construction process and provides professional guidance and support, which has been highly recognized by the client.

Currently, the project has been operating steadily for several months, and the production of high-quality sand and gravel aggregates has effectively filled the demand gap for high-quality construction sand in local infrastructure projects. This project has made positive contributions to environmental protection and solid waste resource utilization, becoming an example of green development in the local area.

Project details:

The project is divided into two phases: the first phase is a fixed crushing production system, and the second phase is a sand-making and shaping system.

Processed materials: granite, construction waste
Project output: 300 tons per hour
Feed size: ≤800mm
Discharge size: 0-5mm, 5-10mm, 10-25mm
Product usage: concrete mixing plant materials

Equipment configuration: PE jaw crusher, HST single-cylinder cone crusher, HPT multi-cylinder cone crusher, VSI6X sand making machine, equipped with F5X series vibrating feeder, S5X series circular vibrating screen, and other auxiliary equipment.

This project processes granite and building materials into high-quality aggregates suitable for high-grade concrete, improving the fluidity and workability of the concrete and reducing the amount of cementitious materials used. The project also optimizes aggregate grading.

Process Analysis:

The overall solution adopts a three-stage closed-circuit crushing scheme, aiming to balance the crushing ratio of each stage to achieve better crushing effect. Coarse crushing is done using a PE jaw crusher, with a deep cavity design to increase material throughput and improve production efficiency. Medium crushing is done using an HST single-cylinder cone crusher, resulting in greater degree of material crushing and reduced load on the fine crushing equipment. Fine crushing is done using an HPT multi-cylinder cone crusher, further optimizing the crushing effect and producing cubic-shaped output with high product yield. The project uses high-energy efficient main equipment, combined with multi-stage crushing and sand-making shaping process, resulting in high-quality aggregates with a full and round particle shape, meeting the requirements for high-quality aggregates.

Project Advantages:

The entire project adopts an intelligent control system and a real-time monitoring system, which not only saves manpower but also enables precise control of equipment operation status, ensuring product quality. The functional zoning of the production line is clear and concise, with fixed line modules placed in a modular manner, meeting the requirements of industrialization and scale production, and improving post-management efficiency. The intelligent screening and washing process effectively reduces the powder and mud content of the finished aggregates, resulting in clean aggregates. The appearance of the production line is designed as a fully enclosed warehouse, effectively isolating dust and noise pollution during the production process, achieving a combination of economic and environmental benefits.

Customer Evaluation:

During the site visit, the project leader said, “Liming Heavy Industry has a complete service system and professional technical support. They completed the project from the initial design to stocking and delivery within the estimated time, and successfully completed the commissioning work. Currently, the production line is running very smoothly, and we are very satisfied with the production capacity and the quality of the finished products!”
