STEEPLY INCLINED CONCENTRATOR Russian patent published in 2003 - IPC

FIELD: mineral classification and concentration. SUBSTANCE: concentrator has branch pipe for supply of initial material and installed above branch pipe for water injection and at inlet of water flow at the first section in the form of parallelepiped inclined relative to longitudinal vertical plane and provided with steeply inclined plates parallel to side walls of section and spaced from one another at equal intervals, and made with riffles. In this case, the second section with inclined plates is made in the form of funnel whose width gradually increases in direction of pulp flow, and height is respectively reduced. Section plates are suspended, riffled and installed from section beginning. Upper and lower suspended riffled plates length reaches branch pipe for removal of tailings, and length of middle plate equals 3/4 of upper plate length. Plates of the first and second sections are installed for vibration from external sources. The first section part behind the concentrate accumulator has additional accumulator for middlings and valve for their discharge. EFFECT: higher efficiency of operation and fuller recovery of heavy materials. 3 dwg
