Sand-making production line

Product Overview

The complete intelligent sand-making production line integrates material conveying, multi-stage crushing, precision sand making, screening and washing, and intelligent control functions, making it a modern, all-in-one sand and gravel processing equipment. The equipment features two core models—the MR sand maker and the DM high-pressure roller sand maker—employing internationally advanced sand-making technology, with an overall technical level that leads the industry. The standard production capacity of the line ranges from 50 to 500 t/h, capable of processing various ores, rocks, as well as industrial solid waste and construction debris, widely serving sand and gravel yards, building material plants, road infrastructure projects, concrete mixing stations, and other applications. We provide one-stop complete equipment solutions and end-to-end technical support, making this equipment the core machinery for large-scale, standardized production of high-quality manufactured sand.

Composition of the Complete Equipment Set and Production Process

This production line is scientifically and comprehensively configured, with core units including a vibrating feeder, jaw crusher, MR sand maker/DM high-pressure roller sand maker, vibrating screen, sand washer, belt conveyor, and an integrated electrical control system. Each piece of equipment operates in coordination, forming a closed-loop automated production process.

Quantitative feeding: The vibrating feeder ensures uniform, continuous material conveyance, maintaining stable feeding conditions.

Primary coarse crushing: Large raw stones are fed into the jaw crusher for coarse crushing, producing medium- and small-sized materials to reduce the load on subsequent sand-making processes.

Fine sand-making and shaping: Materials are sent to either the MR sand maker or the DM high-pressure roller sand maker for fine crushing and shaping operations. These two models can be flexibly selected and combined according to raw material hardness, production capacity, and finished product requirements.

Multi-stage screening: After sand-making, materials are conveyed via belt to the vibrating screen, where they are graded to separate sand and gravel aggregates of different specifications. Materials that fail to meet size standards are returned to the sand-making equipment for secondary processing, achieving circular utilization.

Washing and impurity removal: Qualified aggregates are sent to the sand washer to remove soil, dust, and other impurities, enhancing the cleanliness of the finished product.

Intelligent management: The integrated electrical control system enables centralized, automated control throughout the entire process, allowing precise and convenient equipment start-up, shutdown, and process adjustments.

Technical Advantages of Core Sand-Making Equipment

The production line is equipped with self-developed MR sand makers and DM high-pressure roller sand makers, incorporating internationally advanced technologies that effectively address the shortcomings of traditional sand-making equipment, placing their overall performance at the forefront of the industry.

Both models can operate independently or be seamlessly integrated with crushing, screening, and washing equipment, adapting to diverse production conditions. These machines deliver high sand-making efficiency and excellent material shaping results, producing manufactured sand with rounded particle shapes, reasonable gradation, and low impurity content—all meeting the stringent standards required for high-end engineering sand and gravel applications.
