Project Name: Tianjin Port Navigation Annual 2 Million Tons Aggregate Production Line New Construction Project

Project Overview

Project Location: No. 286 Hanyu Road, Yangjiapo Town Industrial Cluster Area, Binhai New Area, Tianjin (within the factory area of Tianjin Port Navigation Piling Co., Ltd.)
Design Capacity: Annual production of 2 million tons of high-quality aggregate (equivalent to about 300~350 t/h hourly, operating 6000~7000 hours per year)
Construction Content: Three workshops, raw material warehouse, silo, etc., with a total construction area of 9599.39 m²
Project Features

This project adopts a full set of domestically produced high-end equipment from Baotong Group. The process design is standardized and modular, with compact and beautiful equipment layout, high automation level, fully reflecting the three core concepts of modern aggregate production lines: efficiency, environmental protection, and intelligence.

The entire process flow is smooth and precisely connected, from coarse crushing, medium and fine crushing, sand making and shaping to screening and washing. Each link is seamlessly connected to ensure excellent gradation and full particle shape of the finished aggregate, fully meeting the stringent requirements of high-grade concrete, high-grade pavements, and precast components.

Core Equipment Configuration

Mainly equipped with Baotong manufacturing, achieving domestic high-end equipment replacement for imports.

Phase One: Coarse Feeding and Primary Crushing

Equipment Name

Raw materials are uniformly and continuously fed into 2 units of 1060 jaw crushers through two stages of heavy plate feeders for coarse crushing, initially crushed to below 200 mm, providing stable and qualified feed for subsequent medium and fine crushing.
Phase Two: Medium and Fine Crushing and Shaping

Single-cylinder Hydraulic Cone Crusher

Raw materials are uniformly and continuously fed into 2 units of 1060 jaw crushers through two stages of heavy plate feeders for coarse crushing, initially crushed to below 200 mm, providing stable and qualified feed for subsequent medium and fine crushing.
Phase Three: Sand Making and Shaping

Vertical Shaft Impact Sand Making Machine

Raw materials are uniformly and continuously fed into 2 units of 1060 jaw crushers through two stages of heavy plate feeders for coarse crushing, initially crushed to below 200 mm, providing stable and qualified feed for subsequent medium and fine crushing.
Phase Four: Fine Screening and Gradation Optimization

Circular Vibrating Screen (Two Layers)

Raw materials are uniformly and continuously fed into 2 units of 1060 jaw crushers through two stages of heavy plate feeders for coarse crushing, initially crushed to below 200 mm, providing stable and qualified feed for subsequent medium and fine crushing.
Phase Five: Sand Washing and Fine Sand Recovery

Wheel Sand Washer

Raw materials are uniformly and continuously fed into 2 units of 1060 jaw crushers through two stages of heavy plate feeders for coarse crushing, initially crushed to below 200 mm, providing stable and qualified feed for subsequent medium and fine crushing.
The 0~5 mm manufactured sand screened out enters 2 XS6000 wheel sand washers for deep cleaning to remove surface clay powder and impurities; the sand washing overflow water is efficiently recovered by 2 fine sand recovery machines to reduce resource loss; finally, it undergoes final dehydration through 1 unit of 2040 dehydration screen, outputting clean, low-moisture, high-quality finished sand.

Core advantages of the project

① Localization and high-end equipment

• The entire line uses high-end crushing, screening, sand making, and washing equipment independently developed and manufactured by Baotong Hongye Group.
• Core equipment technologies such as single-cylinder hydraulic cone crusher and vertical shaft impact sand making machine are mature and stable in performance, fully replacing imported equipment and reducing investment costs by 20%~30%.

② Standardized and aesthetic process flow

• Compact and reasonable overall layout, smooth equipment connection, with aesthetically designed belt conveyor corridors and silos.
• Fully or semi-enclosed plant design, equipped with efficient dust removal and noise reduction systems, meeting Tianjin's high environmental protection standards.

③ Excellent quality of finished aggregates

• Crushed stone: cubic particle shape, low flaky content, continuous grading, fully meeting GB/T 14685 "Construction Pebbles and Crushed Stone" Class I standards.
• Manufactured sand: adjustable fineness modulus (2.6~3.0), mud content ≤1%, MB value (methylene blue value) ≤1.4, meeting GB/T 14684 "Construction Sand" Class I standards.

④ High level of intelligence and automation

• Equipped with centralized control system (DCS/PLC) for one-button start/stop, remote monitoring, fault diagnosis, and real-time production statistics.
• Key equipment is equipped with online monitoring and early warning systems (bearing temperature, vibration, oil pressure, etc.) to reduce unplanned downtime.

⑤ Environmental protection and resource saving

• Sand washing water recycling rate ≥90%, equipped with sedimentation tanks and filter press systems to achieve zero or compliant wastewater discharge.
• Fine sand recovery rate ≥95%, significantly reducing resource loss and improving economic benefits.
• Dust collection and treatment efficiency of the entire line ≥99%, noise controlled at ≤85 dB (plant boundary), meeting urban industrial area environmental standards.

Technical performance indicators

Application scenarios and market prospects

The high-quality aggregates and manufactured sand produced by this production line can be widely used in:

• High-grade concrete: C30~C60 commercial concrete, ready-mixed mortar
• Highways and municipal roads: asphalt pavement, water-stabilized base
• Rail transit: subway, light rail, high-speed rail
• Prefabricated components and assembled buildings: PC components, pipe piles, bridge prefabricated parts
• Ports and marine engineering: breakwaters, docks, artificial islands

As Tianjin is the core area for coordinated development of Beijing-Tianjin-Hebei and an important northern port city, the demand for construction sand and gravel aggregates is strong and continuously growing. This project’s annual output of 2 million tons of high-quality aggregates will strongly support regional key engineering construction needs, with good economic and social benefits.

Summary

The Tianjin Port and Shipping annual 2 million ton crushing and sand making production line, centered on Baotong Hongye Group's localized high-end equipment, adopts a five-stage linkage process of "coarse crushing → medium and fine crushing → sand making and shaping → multi-stage screening → sand washing and purification," achieving comprehensive goals of high capacity, high quality, high intelligence, and high environmental protection.

The overall project layout is standard and aesthetically pleasing, the process flow is scientific and efficient, and the equipment performance is stable and reliable. It is a model project for a modern aggregate production base in Tianjin and even the Beijing-Tianjin-Hebei region, setting an industry benchmark for promoting high-quality development and green transformation in the sand and gravel industry.
