c82613 · 1997-12-23 — The tariff classification of various machines used in sand reclamation from England
With your inquiry you submitted literature depicting various machines used in metal foundries for the mechanical reclamation of chemically bonded sands. The Vibra-Class machine combines simple mechanical attrition of sand lumps with screening and classification of the sand. It incorporates carbon steel wear plates, a vibratory motor, and three screening stages: a primary carbon steel screen, a secondary stainless steel wedge wire screen, and a tertiary screen through which the sand flows "upside-down" or in a backwards path in order to trap oversize agglomerates or metal flash. Depending on…
889984 · 1993-10-08 — The tariff classification of a coal classifier from Denmark
The HEP (High Efficiency Pressurized) Dynamic Classifier is used to separate pulverized coal particles in order to improve the output of coal burning power plants. Ground coal particles from a pre-existing pulverizer are carried through the machine's pre-separation vanes, which reject the coarsest particles. The flow of remaining coal particles passes through adjustable louvers in the unit and is then directed tangentially to a rotor. Based on rotor speed, tangential velocity and air flow, smaller and lighter coal particles are separated from the heavy particles. The resulting mixture of air…
852168 · 1990-05-21 — The tariff classification of mineral separating machinesfrom Australia
The spiral concentrator is a machine used to separate minerals from a slurry based on the weight and density of the mineral particles. Each spiral concentrator consists of a bank of individual columns which are shaped like a helix. Each column contains up to ten individual spirals, referred to as starts, supported on a three-legged stand. An individual column also contains a feed distributor, splitter box, pressure distributor, splitter plate adjustment mechanism, and a support frame. The spirals are made of fiberglass and are coated with a wear resistant material. The feed distributor is…

25, 1990 on behalf of American Olean Tile Co. you requested a tariff classification ruling. You inquired about the following articles, which are used in a ceramic tile manufacturing plant: 1. Mixer - a machine specially designed to mix the various clays with water. 2. Blunger - a machine used to thoroughly homogenize the clay and water into a slurry. 3. Spray dryer - a machine used to remove excess moisture from the particles of clay by means of heat. 4. Screener - a machine containing a vibrating sieve to remove oversize particles of dried clay. The applicable subheading for the mixer and…
