Grain Cleaning

Screening, aspiration and destoning equipment that removes impurities before they damage your downstream process.

Core Advantages

Why GSS cleaning lines deliver cleaner grain with less loss and less downtime.

01

Staged Cleaning

Primary screeners, vibrating screeners and aspirators remove coarse, fine and light impurities in the right order.

02

Density-Based Destoning

The specific gravity destoner separates stones and heavy objects by density — even when sizes match the grain.

03

High Separation Efficiency

Tuned air volumes and screen surfaces lift out dust, husks and light foreign matter without carrying grain away.

04

Low Grain Loss

Adjustable settings keep good kernels in the clean stream, protecting yield at every cleaning stage.

05

Quick Screen Changes

Automatic tensioning and accessible screen decks make size changes and daily maintenance fast and safe.

06

Global MRO

Screens, bearings and aspiration spares are stocked and serviced worldwide.

Why Choose GSS

Cleaning equipment engineered as the first stage of your whole plant, not a stand-alone box.

Frequently Asked Questions

Answers to the questions we hear most about GSS grain cleaning.

What equipment is in the GSS grain cleaning range?
The range covers primary cleaning screeners, vibratory cleaning screeners, the automatic tensioning type-A screener, air separators and aspirators, and the specific gravity classifying destoner — a complete chain from coarse impurities down to stones.
Which machine removes which impurity?
Screeners take out oversized and undersized particles by size, aspirators lift dust, husks and other light impurities by air, and the gravity destoner removes stones and heavy objects by density — together they cover the full impurity spectrum.
Can the equipment handle different crops and capacities?
Yes. Screen decks, air volumes and machine sizing are configured to your crop (wheat, maize, paddy, soybean and other grains and oilseeds) and your peak intake rate, from farm stores to port terminals.
How much grain is lost in the cleaning process?
Loss is kept low by design: adjustable screen slots and air volumes let operators tune each stage to the crop, so impurities leave and good kernels stay in the clean stream.
Do you provide installation and after-sales support?
Absolutely. Every project includes on-site installation, commissioning and operator training, backed by our global MRO and spare-parts network.
