Product Introduction
The primary crushing equipment of the building aggregate production line is located at the front end of the crushing process. It is mainly used to coarsely crush large raw materials such as rocks and ores (particle size is generally greater than 500mm) to between 40mm-150mm, providing suitable feed particle size for subsequent medium and fine crushing and screening. Common equipment includes jaw crushers, heavy hammer crushers and impact crushers.
Product Advantages
Large-size Feed Port
The feed port size of the primary crushing equipment of the building aggregate production line is up to 860×1520mm, which can directly handle large stones greater than 600mm without pre-crushing and screening of the materials.
Efficient Crushing Chamber
The equipment adopts a deep cavity structure combined with a multi-stage impact plate, which can realize multiple impact crushing of materials in the cavity, with higher single crushing efficiency and a crushing ratio of up to 20:1, greatly reducing the need for subsequent secondary crushing.
Long Life Of Wearing Parts
The lining plate and hammer of the crushing chamber are made of high chromium alloy material, with Rockwell hardness of up to HRC 58-65, which is not easily worn by materials, and the average service life exceeds 400 hours, which significantly reduces the replacement frequency.

Process Optimization Solutions for Construction Aggregate Production Lines
Primary crushing:Jaw or gyratory crushers break large stone blocks into 100–300mm;
Secondary crushing:Cone crushers further crush materials to 30–80mm;
Tertiary crushing:Impact crushers or vertical shaft impact crushers (VSI crushers) shape the materials to produce 5–31.5mm finished aggregates.
Closed-loop circulation system:Screening equipment is installed in the secondary and tertiary crushing stages. Unqualified materials are returned to the previous-stage crusher for reprocessing, ensuring the particle size qualification rate of finished aggregates exceeds 98%.
2. Intelligent production control system
AI feeding adjustment: through visual sensors to detect the stone particle size and feeding amount in real time, relying on AI algorithms, it can automatically adjust the frequency of the feeder to avoid overloading or idling of the first break equipment.
Equipment health management: comprehensive deployment of IoT sensors, real-time detection of the wear degree of the jaw plate, the temperature change of the bearings, and the pressure value of the hydraulic system and other important parameters. The predictive maintenance system can accurately warn of possible equipment failures 72 hours in advance, reducing downtime.

FAQ
Q: How long is the production cycle of the equipment?
A: Under normal circumstances, the production cycle of standard models is 15-20 working days, and the customized models need to be evaluated based on technical parameters, with a cycle of about 25-30 working days. The specific time can be specified in the contract.
Q: Does the equipment support customization? What is the customization process?
A: Support customization. The process is: provide on-site working conditions and production requirements → Engineers issue plan drawings → Both parties confirm technical parameters and quotations → Sign a contract → Scheduling production → Delivery and installation services.
Q: What are the transportation methods? How long does it take for the equipment to be delivered to the site?
A: We support road transportation, rail transportation and sea transportation (applicable to export orders). Domestic shipments can generally be delivered to the customer's designated location within 7 days, and exports depend on the port and customs clearance time, which is expected to vary from 15 to 40 days.
Q: Does it support installment payment or letter of credit?
A: It supports multiple payment methods, including telegraphic transfer (T/T), letter of credit (L/C), installment payment (subject to separate approval), etc. The specific terms can be negotiated based on the cooperation amount and the customer's credit.
Q: Is the discharge particle size of the primary crushing equipment of the building aggregate production line adjustable?
A: It can be adjusted. The discharge particle size range is generally 40mm to 150mm. By adjusting the gap between the impact plate or replacing the screen plate structure, different particle size requirements can be met.
