Technological Scheme of a Sand and Gravel Plant

Optimized Production Process for Maximum Efficiency

The technological scheme of a sand and gravel plant designed by Liming Heavy Industry integrates advanced crushing equipment, intelligent control systems, and environmentally friendly solutions to deliver high-quality aggregates for construction and infrastructure projects.

Core Equipment Configuration

Primary Crushing Stage

Our C6X Series Jaw Crusher handles the primary crushing of raw materials with its durable structure and high crushing ratio. For larger projects demanding greater capacity, the HGT Gyratory Crusher provides superior throughput up to 2020t/h.

Secondary Crushing Stage

The HPT Hydraulic Cone Crusher performs intermediate crushing with adjustable discharge sizes and automated hydraulic adjustment system, achieving particle shape optimization.

Tertiary Crushing & Sand Making

The revolutionary VSI6X Sand Maker processes finer materials into high-quality manufactured sand with exceptional gradation control. Its optimized impeller design significantly reduces wear costs.

Screening System

The S5X Vibrating Screen series provides precise classification with multi-layer screening decks and high screening efficiency (+85%).

Advanced Technological Features

Intelligent Control System

Our plants incorporate PLC-based automation that monitors equipment status, optimizes production parameters, and ensures stable operation while reducing labor costs.

Dust Suppression System

Closed-type design combined with high-pressure mist spray systems maintains dust levels below 15mg/m³, complying with strict environmental regulations.

Mobile Configuration Option

For temporary projects or remote locations, our NK Series Mobile Crushing Stations provide flexible deployment with quick setup times.
