40,000 T/Y Granite Sand Making Production Line in Hunan

Core Equipment：CRS Sand Making Machine

Processed Materials：Granite（≤20mm）

Production Output：6~10t/h

Powder Fineness：20~120 mesh

Customer Feedback

The CRS Sand Making Machine not only produces four grades of finished sand with stable output, but its built-in collection system also efficiently recycles tailings into high-quality 325 mesh filler. This not only addresses environmental challenges but also generates significant additional revenue. The professional services provided by Cronus Machinery offered strong support for the smooth commissioning of the project.

Project Overview

A new building materials enterprise in Hunan decided to invest in building a granite sand-making production line. The project required producing sand products of different specifications while also recycling the tailings powder, achieving the goal of "harvesting both sand and powder, turning waste into treasure." After comprehensive evaluation, the CRS Sand Making Machine from Cronus Machinery, paired with a cyclone collector, was selected. This innovative solution addresses the tailings powder processing challenge, contributing to the sustainable development of the imitation stone paint industry.

Project Details

Granite Raw Material → Raw Material Silo → Belt Feeder → Sand Making Machine → Square Swing Screen

Granite material stored in the raw material silo is fed into the CRS Sand Making Machine via the belt feeder for crushing and shaping, producing high-quality aggregate that meets the requirements for imitation stone paint. The mixed material after sand making enters the square swing screen, where it is precisely screened into four target specifications of finished sand: 20~40 mesh, 40~60 mesh, 60~80 mesh, and 80~120 mesh.

Cyclone Collector → Finished Product Packaging

The fine powder (tailings powder) naturally generated during the sand-making process is efficiently recovered by the cyclone collector. This tailings powder requires no additional processing; its fineness meets 325 mesh, allowing it to be directly sold as high-quality filler to putty powder factories, creating additional revenue.

Main Equipment	Function Description
Raw Material Silo	Stores granite raw material
Belt Feeder	A feeding and conveying device with variable frequency speed control
CRS Sand Making Machine	Crushes and shapes granite material with a particle size of ≤20mm into sand-like particles
Square Swing Screen	High screening accuracy, large processing capacity, capable of simultaneously producing multiple specifications of finished sand
Tailings Powder Collection System	Efficiently recovers tailings powder, achieving zero-waste production

Project Advantages

Precise Classification: The CRS Sand Making Machine, combined with the high-precision square swing screen, can simultaneously and stably produce four specifications of premium sand: 20~40 mesh, 40~60 mesh, 60~80 mesh, and 80~120 mesh.

Tailings Powder Recovery: Innovatively integrates a cyclone collector to directly recover what was traditionally considered waste (tailings powder) into high-quality filler with a fineness of 325 mesh, which can be sold to putty powder factories without secondary processing.

Intelligent and Eco-friendly: The entire process adopts a sealed negative pressure design with high dust collection efficiency, transforming tailings powder into a resource, perfectly aligning with green and sustainable development.
