The J+A screw classifier systems are free-standing units used for the separation of mineral grit from other types of solids. The screw classifier hopper maintains the required water level through a series of weirs. A peripheral weir removes floating solids and a second weir, positioned within the trough wall, removes other solids that are lighter than grit.

Shafted Submerged Grit Collection Screws. Shafted screw conveyors are most commonly used in submerged grit collection applications. With a shafted screw conveyor there is no wear liner like shaftless screws need. A shafted screw conveyor in this application will need hanger bearings when the length is over 18 ft long.

The Spiral Classifier offers the greatest sand raking capacity of any classifier available. (3) The tank is a heavy plate with a strong structural base. The extra heavy shaft has an improved submerged bearing. The greatest improvements, however, are found in the drive-unit which has been strengthened and improved over all other classifiers.

It is designed to effectively separate and settle the grit from the water. Sismat Uluslararası provides versatile, long-lasting and easy-to-install grit classifiers operating ...

GRIT CLASSIFIERS • High separation performance • Dry solid material discharge • Smooth decomposition of the small or large particles • Without bearings, and without water leakage design • Low installation and maintenance costs • Shaftless heavy-duty screw ensuring durability • No submerged bearings or seals required

the shaftless screw and the elimination of any submerged bearings, will provide you with a machine life cycle that is unmatched by other equipment available in the market place. Although the majority of the washer/compactor components are manufactured from 304SS,

The Spiral Classifier offers the greatest sand raking capacity of any classifier available. The tank is heavy plate with strong structural base. The extra heavy shaft has an improved submerged bearing. The greatest improvements, however, are found in the drive-unit which has been strengthened and improved over all other classifiers.

The lower bearing has been moved up along the conveyor shaft to a point above the pulp level, thus eliminating the wear and repair which formerly resulted from sand getting into the bearing when it was submerged. ... Spiral-Screw Classifier Capacity Table.

Grit Classifiers or also known as a grit screw, grit separator or grit classifier are used at wastewater plants at the headworks (front end of the plant) to help separate the grit from organics and water. Grit removal needs to be done at the headworks of plants to help reduce wear to upstream pumps and mechanical equipment. Grit can also cause pipe blockage and reduce the effective volume of ...

Use of a Grit Classifier will assure you of many years of uninterrupted service. The use of stainless steel trough and reservoir, together with the non-clogging features of the shaftless screw and the elimination of any submerged bearings, will provide you with a machine life cycle that is unmatched by other equipment available in the market place.

Spiral classifier (Screw classifier) is another Sand washing machine and is widely used for washing various ores, aggregates and sands at crushing plant and sand plant. Advantages of Spiral classifier are simple structure, reliable working condition and convenient operation. ... The additional heavy shaft has an improved submerged bearing ...

Screw Classifier and De-Waterer. The spiral classifier offers the greatest sand / mineral raking capacity of any mining classifier available. Heavily constructed, the tank is made from heavy plate steel along with a strong structural base. The extra heavy support shaft has an improved, submerged bearing offering far greater protection than ...

2. Low weir spiral classifier. The overflow weir of the low weir type spiral classifier is usually lower than the center of the bearing at the overflow end. Therefore, the settlement area is too small and the overflow production capacity is too low, and the screw agitation on the pulp surface is too large.

Application of spiral classifier Spiral Classifier is widely used in mineral processing plant to match with the ball mill and form a closed-circuit circulation to process mining sand, or used in gravity mine-selection plant for classifying sand and mine m. Classifier,Spiral separator,Screw classifiers,Mining .

2) Low weir spiral classifier. The overflow weir of the low weir type spiral classifier is usually lower than the center of the bearing at the overflow end. Therefore, the settlement area is too small and the overflow production capacity is too low, and the screw agitation on the pulp surface is …

There are four types of classifiers: high weir type single screw and double screw, submerged single screw and double screw. The classifier is mainly composed of transmission device, spiral body, trough, lifting mechanism, lower support (bearing) and discharge valve. Spiral Classifier Advantages: 1、Simple structure, easy to maintain

The submerged spiral classifier is more suitable for the overflow products (less than 0.15mm) because of stable classifying surface, high overflow output and fine particle size, which is often used as combined unit by combining with the grinding mill in the second stage grinding. 2. The number of screw …

• No submerged bearing or parts reduces maintenance • Optional all-stainless steel construction for superior corrosion resistance.
