Product Overview

The aggregate production line is a complete set of equipment for producing construction sand, crushed stone, and stone powder. It consists of feeders, heavy-duty impact hammer crushers, sand making machines, heavy-duty vibrating screens, sand washing machines, and belt conveyors connecting them into an integrated production line. After materials enter the heavy-duty impact hammer crusher, they are crushed through the "rock-on-rock" and "rock-on-iron" crushing principles. The design features no grate bars, allowing materials with moisture content below 15% to be processed. The entire crushing process is simplified with a large crushing ratio, enabling large feed materials up to 1 meter to be crushed to below 70 mm in a single pass, and ideal particle shapes are obtained through vibrating screening.

Application Range

The aggregate production line is mainly suitable for crushing and shaping of soft to medium-hard materials. It is widely used in various ores, cement, refractories, bauxite clinker, emery, glass raw materials, manufactured construction sand, stone materials, etc. For brittle materials such as limestone and bluestone, it offers a larger crushing ratio than other types of crushers, produces better finished particle shapes, and is easy to maintain. With the same investment, its output far exceeds that of other crushers.

Process Flow for 800‑1000 t/h Aggregate Production Line

Large stones from the hopper are evenly fed by a vibrating feeder into the primary crusher (heavy-duty impact hammer crusher) for coarse crushing. The coarse crushed stones are then conveyed by belt conveyor to the secondary crusher (hammer crusher) for further crushing. The finely crushed stones are then sent by belt conveyor to a vibrating screen for screening, producing two types of finished materials. Stones meeting the size requirement are conveyed by finished product belt conveyor to the stockpile; stones not meeting the size requirement are returned by belt conveyor to the secondary crusher for re‑crushing. The re‑crushed materials are sent to the next screen for screening, forming a closed‑loop multi‑cycle process. The final particle size can be combined and graded according to user requirements. Auxiliary dust collection equipment can be added for environmental protection.

Features of the Aggregate Production Line

• Automation and intelligence: The entire production line features a high degree of automation. Apart from startup, shutdown, and routine maintenance, the process is simple and operation convenient. It also meets high-end industry demands by offering intelligent control via computer, allowing one‑button operation, significantly reducing labor costs and improving efficiency.
• High efficiency and energy saving, significant returns: Large crushing ratio, high crushing efficiency, excellent production capacity, large processing capacity, and low operating cost. Finished stones are uniform in size, well‑shaped, and properly graded. Manufactured sand meets national construction sand standards, bringing higher returns to customers.
• Scientific configuration, compact footprint: The entire equipment set is reasonably configured with a compact layout, small footprint, and high investment efficiency. Low stone powder yield balances environmental protection and economy.
• Durable, easy maintenance, long service life: Maintenance is simple. Wear parts are made of high‑impact‑resistant materials with low consumption, effectively extending equipment service life and reducing downtime and maintenance costs.
• Wide application range: Successfully applied in crushing limestone, bluestone, coal gangue, and other rocks. Finished aggregates can directly supply highways, railways, water conservancy, concrete batching plants, and other industries, meeting multi‑field production needs.
• Environmentally compliant and fully controllable: Strictly follows the "Three Simultaneities" principle (pollution control facilities designed, constructed, and put into operation simultaneously with the main project). Environmental protection concepts are integrated from the initial plant construction stage to create a green production line.
• Customization and worry‑free after‑sales service: As a professional manufacturer, Xinxiang Tongxin Vibrating Machinery can customize equipment configurations according to customer requirements for stone specifications, output, and application. By combining on‑site topography, actual measurements, and precise drawings, we optimize layouts. We provide comprehensive pre‑sales, in‑sales, and after‑sales services, with professional installation teams for on‑site construction. After‑sales service arrives at the site within 24‑48 hours for repairs, ensuring stable operation of the production line.
