Products classified under HTS 8474.10.00
Aggregate Dewatering Screen
A dewatering vibrating screen removes water from washed sand and gravel aggregates using high-frequency vibration. Classifies under HTS 8474.10.00 as screening/washing for mineral substances.
Rotary Ore Trommel Screen
A rotary trommel screen tumbles ore in a rotating drum with perforated sections to screen and wash minerals by size. HTS 8474.10.00 for combined screening and washing of solid minerals.
Density Separator for Minerals
An autogenous dense media separator uses fluidized bed for density-based separation of coal or ores. Fits HTS 8474.10.00 for separating solid mineral substances.
Stone Powder Classifier
An air classifier separates fine stone powders from coarser particles using centrifugal air flow in mineral grinding circuits. Under HTS 8474.10.00 for screening mineral powders.
Flotation Cell Agitator Separator
A mineral flotation cell with impeller separates valuable minerals via air bubbles in pulp, though primarily separating. Borderline HTS 8474.10.00 if classified as mineral separator.
Wafer Crystal Grinder
Precision grinder for shaping semiconductor crystal boules to exact diameter before wafer slicing, as per statistical notes. While grinding, classified under HTS 8474.10.00 if part of sorting/screening prep per notes.
Vibrating Screen Separator
A vibrating screen separator is used in mining and aggregate processing to sort and screen ore, stone, and other mineral substances by size. It employs vibration to separate particles into different grades, falling under HTS 8474.10.00 as machinery specifically designed for screening and sorting solid mineral materials.
Ore Sorting Machine
An automated ore sorting machine uses sensors and air jets to separate valuable ore from waste rock based on color, density, or composition. Classified under HTS 8474.10.00 for its role in sorting mineral substances in solid form during mining operations.
Sand Washing Plant
A sand washing plant scrubs and rinses silica sand or aggregate to remove clay, silt, and impurities using water and mechanical agitation. It fits HTS 8474.10.00 as washing machinery for mineral substances in solid form like earth and stone.
Mineral Spiral Concentrator
A spiral concentrator separates heavy minerals like gold or iron ore from lighter gangue using gravity and helical chutes with water flow. Under HTS 8474.10.00 for separating solid mineral substances in mining applications.
Gold Ore Shaker Table
A Wilfley shaker table uses riffles and vibration with water to concentrate gold-bearing ores by specific gravity. Classified in HTS 8474.10.00 for separating mineral substances in solid form.
Quarry Vibrating Grizzly Feeder Screen
A grizzly feeder screen with heavy bars vibrates to scalp oversized rocks from quarry stone before primary crushing. HTS 8474.10.00 covers this screening machine for stone and mineral sorting.
Magnetic Ore Separator Drum
A rotating magnetic drum separator pulls ferromagnetic minerals like magnetite from ore slurries or dry feeds. Under HTS 8474.10.00 for magnetic separating of solid mineral substances.
Crushing Screen Combo Unit
A mobile crushing and screening plant combines jaw crushing with vibrating screens to process and sort quarried stone into aggregates. Primarily classified under HTS 8474.10.00 if screening function dominates for mineral sorting.
Coal Washing Jig
A Baum jig washer stratifies and separates coal by density using pulsating water beds to remove ash and impurities. Falls under HTS 8474.10.00 as washing and separating machinery for solid mineral fuels.
