Classification of spiral chutes

Classification of spiral chutes: 1. Introduction: Gravity beneficiation is widely used in the beneficiation of metal and non-ferrous metals due to its small environmental pollution and low cost. The fiberglass spiral chute is a type of gravity separation machinery, characterized by a cubic parabolic shape on the cross-section, suitable for handling finer particle levels of -0.2MM. In the selection process, there is no need to add flushing water, and fine, medium, and tailings are segmented at the tail end of the chute. 2、 Use the method to erect the spiral chute, calibrate the vertical line, fix it in the proper position with iron frame or wood, let the sand ore be sent to the two feeding ports on the top of the spiral by the slurry pump, add water, adjust the density of the mineral slurry, the mineral slurry naturally swirls from top to bottom, and generate a single coherent centrifugal force in the rotational slope flow speed, which can be distinguished by the specific gravity, Granularity and state of the mineral sand, Through the gravity and centrifugal force of swirling flow, the ore and sand are separated, and the selected ore is discharged into the concentrate hopper and connected out through pipelines. The tailings are discharged into the tailings hopper and transported to the sand pit through pipelines, and then discharged by a sand pump, completing the entire process of beneficiation. The classification of spiral chutes: 3. Characteristics and advantages: 1. Superlarge-scale, large processing capacity, modern mineral processing principles require large-scale creation of benefits. 2. Fine granulation refers to the treatment of fine and small mineral particles, especially the treatment of mineral materials with a particle size of -0.047mm. Originally, the mechanical system could fundamentally ensure the recovery of+0.047mm particles. 3. With the development of Hydraulics, two-phase flow and equipment vibration, spiral chutes have developed from simple use of gravity and water resistance to composite application of centrifugal force, mechanical vibration force, magnetic force, etc. Through a composite force field, the enrichment of useful minerals and the separation of fine and fine particles are increased, resulting in an increase in ore recovery rate. 4. Based on energy saving, environmental protection and consumption reduction, it needs to occupy a small area, space, water and electricity consumption. 5. The simple operation is flexible, the sorting process is stable, and the structure is simple, which is convenient for Computerized maintenance management system. The classification of spiral chutes is . According to the particle size of the processed ore, the chutes can be divided into three types: (1) Coarse grained spiral chutes, with a maximum particle size of 2-3mm or more for ore feeding and a maximum of 100-200mm. (2) Sand ore chute, processing 2-3MM particle grade ore. (3) Slurry spiral chute, feeding Granularity<0.074mm. 5、 Application: FRP spiral chute is suitable for separating fine iron, ferrotitanium, ferrochrome, ferrosulfur, sand tin, tantalum niobium, placer gold, coal, monazite, Rutile, zircon sand, rare earth and other metal and nonferrous metal minerals with completely sufficient specific gravity difference.
