Project Overview

Liming built a limestone crushing and sand making production line for a large building materials company in Sichuan. The project uses high-quality limestone as raw material and adopts intelligent production technology. The annual design capacity reaches 1.2 million tons.

The production line adopts a graded crushing process, which can simultaneously produce three specifications of finished products: 0-3mm fine machine-made sand, 3-8mm melon seed slices and 8-31.5mm gravel, fully meeting the needs of surrounding mixing stations for various types of building aggregates. The project is equipped with advanced equipment that can produce continuously for 20 hours to achieve efficient and stable production operation.

Core equipment configuration

The project selected Liming's cost-effective equipment:

CI5X series high-efficiency impact crusher

VSI6X vertical shaft impact sand making machine

S5X series high-performance vibration screening equipment

Equipped with environmental protection dust removal system

Project advantage analysis

Intelligent production control

The production line adopts Liming's self-developed intelligent control system to realize real-time monitoring and data collection of the entire line of equipment in the central control room. Operators can accurately control various production parameters through the human-computer interaction interface to ensure that the equipment is always in the best condition.

Green and environmentally friendly process

The project adopts a fully dry production process and achieves clean production through four major environmental protection measures:

(1) Equipped with four sets of high-efficiency pulse dust removal systems

(2) All conveyor belts are closed

(3) Key workstations are equipped with intelligent spray dust suppression devices

(4) The site is hardened and greened

Excellent product quality

The production line adopts a multi-stage crushing and screening process to ensure that the finished aggregate has the following characteristics:

(1) The particle size of the machine-made sand is reasonable and the fineness modulus is adjustable

(2) The melon seed slices and gravel products have excellent particle shape and low needle-like content

(3) The powder content of all finished products is controllable and the moisture content is stable

The Liming technical team has specially optimized the following process links based on the characteristics of the project:

The combination of "impact crusher + sand making machine" is adopted to achieve the best energy efficiency ratio

The three-stage grading and screening system is designed to ensure the product grading accuracy

The dual-channel discharge system is configured to improve the flexibility of the production line

The modular layout design is adopted to facilitate the subsequent capacity increase
