Project Requirements Analysis

The goal of this project is to produce four particle sizes (0-5mm, 5-10mm, 10-20mm, 20-31.5mm) of limestone after efficient crushing, and achieve a production capacity of 500-600 tons/hour. The final product will be used in concrete mixing plants, so the quality of each particle size is required to be stable, the particle shape is good, and it meets environmental protection requirements.

In order to meet these requirements, the production line design will adopt a reasonable combination of equipment to ensure efficient crushing, precise screening, and reduce dust pollution through a dust removal system to ensure environmental compliance.

Equipment Configuration List

Equipment Name	Model	Quantity	Main Function

Belt Conveyor	Multiple	Several	Material conveying, ensures material flow
Vibrating Feeder	GZD Series	1	Uniform feeding, prevents material accumulation
PLC Control System	Customized	1	Automation control and monitoring

Project Requirements Analysis

Efficient crushing and precise particle size control: By adopting two-stage crushing (jaw crusher and impact crusher) and three-stage crushing (cone crusher), the limestone crushing efficiency is high and the particle size distribution is uniform.

Efficient screening: The circular vibrating screen can achieve precise screening and separate the required finished products of different specifications (0-5mm, 5-10mm, 10-20mm, 20-31.5mm) to meet the mixing station's requirements for different particle sizes.

Environmental protection and energy saving: The bag dust collector ensures that the production line can operate efficiently while reducing dust emissions and meeting environmental protection standards.

Automation control: The PLC automation control system improves the automation and intelligence of the production line, optimizes the production process, and reduces labor costs.

Project budget and implementation time

Budget: The total budget for equipment procurement, installation and commissioning will be determined based on the equipment model and the actual needs of the production site. The overall budget includes equipment, civil engineering, installation, commissioning and other costs.

Implementation time: It is estimated that it will take 3-4 months from equipment procurement to full production line commissioning, and the specific time depends on the site conditions, equipment delivery cycle and installation difficulty.
