TQSX Suction Type Destoner
TQSX Suction Type Destoner: Precision Stone Separation. The TQSX series uses negative pressure to separate stones from grain by density difference. It helps maintain a dust-free environment and supports stable milling performance for large commercial mills.

Application in Paddy Cleaning and Destoning
This TQSX suction type destoner is used to remove stones, sand and other heavy impurities that are similar in size to paddy. It uses air flow and vibration to separate stones from grain before the paddy enters the husker.
Core FunctionGravity destoning for removing stones and heavy particles from cleaned paddy or grain.
Buyer ValueUses airflow and density differences to separate heavy impurities, protecting the husker, whitener and downstream machines from stone damage.
Line IntegrationPlaced in the front-end cleaning section before husking, where it removes impurities, stones or dust so downstream huskers, separators and whiteners can work more steadily.

Key Features
Cleaner Input Before Husking and Milling
Removes impurities before paddy reaches the husker, protecting downstream equipment and improving process stability.
Targeted Impurity Removal
Selects the machine according to large impurities, light impurities, fine impurities, stones or mixed impurity conditions.
Protects Downstream Machines
Cleaner paddy helps reduce wear and blockage in huskers, whiteners, separators and elevators.
Matched to Capacity
Machine size, sieve area, air volume and cleaning stage are selected according to line capacity and raw grain condition.
Working Principle
How It Works in the Process
It uses the difference of specific gravity and suspension speed between stone and rice,so as to separate them into two layers.The stone and sand go down to the lower layer and go upward along the sieve surface with the reciprocating movement of screen,then discharge from outlet.The rice suspends in upper layer with semi-suspended state,and goes down the sieve surface under the function of gravity and the continuous feeding.Thus achieve the separation.
Input
Raw or pre-cleaned paddy enters the cleaning or de-stoning section.
Separation
Screens, air flow, vibration or gravity separate impurities from useful grain.
Impurity Discharge
Dust, straw, stones or other unwanted materials are removed through separate outlets.
Output
Cleaner paddy moves to husking, storage or the next cleaning stage.

Destoner Selection
When to Choose a TQSX Suction Type Destoner
Choose TQSX when stones and heavy impurities must be removed from paddy or grain by air suction and vibration before husking or further processing.
Stone Removal FocusDesigned for stones and heavy impurities that are close to grain size and cannot be removed by ordinary cleaning screens.
Air and VibrationRequires correct air volume, sieve angle and material layer for stable separation.
Before HuskingInstall after cleaning and before the husker to protect rubber rolls and improve downstream milling stability.

FAQ
Common Questions
How do I choose between cleaner and destoner models?
Selection depends on impurity type, capacity and whether stone removal is required.
Where is this equipment installed?
Usually before husking to protect downstream machines.
Can the machine be matched with dust collection?
Yes, air suction or dust collection can be considered by model.
