VIBROSCREEN® Typical Applications


Separating Solids from Solids

(sifting, de-dusting and classifying)

Separating Solids from Solids

Gravity-fed and in-line pneumatic models

Kason offers VIBROSCREEN® configurations for three types of solids-solids separation:

  1. Sifting (also called "scalping" or "bolting"): Separating a small percentage of oversize solids from a large percentage of on-size solids
  2. De-Dusting: Separating a small percentage of undersize solids from a large percentage of on-size solids
  3. Classifying: Separating solids into two or more particle size fractions

These screeners operate on a batch or continuous basis at rates from several pounds/kilograms to 70 tons per hour, separating thousands of powder and bulk solid materials.

Separating Solids from Liquids

(dewatering, clarifying and liquid scalping)

Separating Solids from Liquids

Gravity-fed models only

 
VIBROSCREEN separators are engineered for three types of solids-liquids separation:

  1. Dewatering: Separating a small to medium percentage of liquid from a large percentage of solids
  2. Clarifying: Separating a small percentage of solids from a large percentage of liquids
  3. Liquid scalping: Separating a small percentage of oversize solids from a large percentage of on-size solids in a slurry

These screeners operate on a batch or continuous basis at rates from one to 2000 gallons (7571 liters) per minute, separating solids from thousands of liquids.

 

Dry Separation

Foods - recovery of rice from hulls, coffee beans from chaff, and tea from bags.

Chemicals and Petrochemicals - catalyst beds are classified into alundum balls, scale, clean catalyst pellets, and dust.

Minerals - separation of rock dust from asbestos shorts, alumina from rotary kiln brick impurities, and stones from pit sand.

Animal Feeds - scalping of foreign material from mash; removal of bone chips from meat meal.

Grains - separation of dockage (wheat, wild oats, etc.) from flax seeds; cleaning of agricultural seeds and grains.
 

Solids/Liquid Separation

Foods - separation of bagasse from sugar melt, casein curd from whey, protein particles from yeast slurry, corn fiber from starch slurry, and gluten from wheat starch; dewatering of fruits and vegetables, spent coffee grounds, potato slices, instant rice, and tuna; clarifying of chocolate liquor, French fry oil, molasses, caustic bottle wash, and apple or citrus juices prior to filtration.

Chemicals - separation of salt from glycerine, polyethylene from extruder water, coagulum from latex, and algins from digestion liquor; dewatering of digested reclaim rubber and T.N.T.; clarifying of polyvinyl acetate emulsions, paints, and enamels.

Pulp - dewatering of rejects before refining; dewatering of knots.
 

Dry Classification

Foods - pea grading, instant coffee powders, ground coffees, dried milk, sugars, salts, cereals, starches, spices, nuts, rebolting flour, sugar, potato powder and flakes, powdered eggs, candies, powdered cheese, and bread crumbs.

Chemicals - polyvinyl chloride, polyethylene, polypropylene and other plastic pellets, melamine, phenolics, cellulose acetate, polystyrene, sodium carbonate, calcium carbide, copper sulfate, detergents, adipic acid, iron oxide, caustic soda flake, di-calcium phosphate, stearic acid, titanium dioxide, zinc oxide, sodium sulfate, potassium iodide, sodium alginate, borax, calcium carbonate, silicon carbide, monosodium glutamate, alum, calcium chloride, and sodium cyanide.

Minerals and Metals - metal powders (aluminum, copper, bronze, nickel, iron, magnesium, etc.), barytes, silica, bauxite, cement, brick clay, coke, fluorspar, limestone, mica, perlite, talc, antimony, dolomite, feldspar, diatomaceous earth, rock salt, and nepheline syenite.

Pulp and Wood Products - wood chips, particle board, sawdust, and wood flour.

Pharmaceuticals - aspirin, boric acid, epsom salts, sodium bicarbonate, tablet de-dusting, and granulations.

Fertilizers - granulated mixes; potash; phosphate rock; urea; and ammonium nitrate, sulfates, and phosphates.

Abrasives - carborundum, aluminum oxide, and blasting silica.

Solids Classification
in Liquid Medium

Solids classification in liquid medium Chemicals - clarify aluminum paint suspension, remove oversize particles from suspensions fed to nozzle centrifuges, dewater Glaubers salt while removing silt, and classify pigments.

Minerals - separate impurities from kaolin slurry prior to centrifuging; classification of silica to remove iron impurities, columbium ore in closed circuit grinding, and cement slurry following ball mills.

Pulp and Paper - recovering usable fiber from mill effluent; classification of starch and coating suspensions, mill and white water to eliminate shower blocking, and barker effluent.

Ceramics - clarify body and glaze slips for whiteware.

Waste Disposal - Clarification of white water from pulp mills, cannery wastes, paunch manure from meat packing, distillery slop.
