The new generation of machines, with its types TS 90-S, TS 180-S and TS 360-S, are operated with aspiration (no-dust escape) and are equipped with the patented flywheel type of drive, ensuring complete balancing of the dynamic forces (= minimum of vibrations).
Dry stoners are used to separate granular material according to the specific weight into two fractions and in dry material condition.
The Cimbria dry stoner is used for separating dry granular material according to specific weight into two fractions. The goal is the elimination of heavy impurities, such as stones, metallic particles and other objects from the food grade processing line or coffee.

Dry stoners are used to separate granular material according to the specific weight into two fractions and in dry material condition.
They find their application mainly in the elimination of heavy impurities, such as stones, metallic particles etc., from coffee, grain, pulse etc.

The machine consists of a self supporting steel section frame, carrying the variable frame with the fly-wheel drive and the adjustment of inclination (6-15°) of the separator table.
The vibrating movement of the table is effected by an eccentric drive (through electric motor and belt drive).
The deck surface is covered by a closed hood, containing large sight glasses and an inspection door. The exhaust duct for the required air consumption is connected to this hood. The required air volume is aspirated through the deck insert, which is permeable to air and can easily be folded down for cleaning or replacement purposes. Air volume and material input are adjusted to each of the required operation conditions by means of adjustable flaps.
The granular material to be separated is fed onto the table deck (in its conveying direction) through an adjustable spring-actuated flap.
Depending on the grain size, the deck surface, with its adjustable inclination of 6-15°, is covered by a fine-meshed or a large meshed wire cloth, through which a steady and adjustable air flow is aspirated.
The combined effect of the vibrating movement and of the air passing through the deck causes an arranging in layers of the material flowing in (fluidization). The heavy admixtures sink towards the bottom and are moved to the highest point of the table deck surface (stone outlet) by the contact with the rough deck covering.
The main produce (clean produce) floats towards the top and flows, against the conveying direction of the table, to the lowest point of the deck surface, the clean produce discharge.
In the outlet area of the heavy particles, a "counter-air flow zone” avoids the clean produce being discharged into the heavy particles outlet during operation.
At the stone outlet an adjustable counter- air flow zone is installed. This is to prevent the good product from being discharged through the stone outlet during operation by means of a strong air stream.
The amount of incoming material can be regulated and therefore an ideal coverage of the deck surface can be achieved. An adjustable spring- actuated flap prevents false air from being sucked in through the material supply pipe.
On request, the machine can be equipped with a residual discharge. Therefore, the sorting table is inclined pneumatically towards the clean product discharge (working- inclination + 8°) so that rapid table emptying can take place.
The machine with its so called "inlet- shoe” supplies itself with the correct amount of product from the material supply pipe arranged in front of the dry stoner.
De-stoners find their application mainly in the food processing sector and in the milling industry, but they are also used on the seed and special crops sector especially on products being harvested close to the ground.
