An ore granulation device and method with adjustable inclination angle and rotating speed

Abstract

The invention provides an ore granulation device and method with adjustable inclination angle and rotational speed, belonging to the technical field of metal ore granulation. The device includes a granulation drum, a partition, a fixed knob, a trapezoidal keel, a rotating support platform, an angle scale, an angle adjustment bracket, an angle adjustment knob, a threaded screw, a main rotating roller, a slave rotating roller, a variable speed motor, a motor bracket, and a transmission devices, stainless steel brackets, leveling nuts, etc. Rotate the threaded screw to open and close the angle adjustment bracket, use the angle scale to observe and determine the current inclination angle, and realize the adjustable inclination angle of the granulation drum; the variable speed motor is connected with the lateral support roller through the transmission system to drive the granulation drum to rotate ; There is a keel inside the granulation drum to improve the efficiency of granulation rolling and granulation; there is an axial support roller inside the rolling guide to ensure that the granulation drum does not move axially during rotation. The structure of the device is simple, the method is practical and convenient, and it can carry out high-efficiency granulation of ore under actual working conditions such as different inclination angles and different speeds.

Description

technical field [0001] The invention relates to the technical field of metal ore granulation, in particular to an ore granulation device and method with adjustable inclination angle and rotating speed. Background technique [0002] my country is a major producer and demander of metal mineral resources, and has become the world's largest importer of metal mineral resources and output of finished metals for 14 consecutive years. However, my country's metal mineral resources have poor endowment, complex mineral composition, and serious secondary associated phenomena. Conventional mining and dressing methods have problems such as high cost and low efficiency, and it is difficult to meet my country's metal mineral demand. The use of ore heap leaching technology can effectively improve the efficiency of ore leaching and recovery of valuable metal resources. However, for the heap leaching of fine ores and precious metal ores with high shale content, such as: high-mud copper oxide ...

Problems solved by technology

[0004] However, the current granulators are mostly focused on the fields of pharmaceuticals and feed, and there are few studies on granulation of ore particles and fine ore, especially for ore granulation devices and methods under multiple working conditions such as inclination angle and rotational speed. The speed and rotation speed can directly affect the contact characteristics of coarse and fine granules and the rolling behavior of granules, which in turn affect the granulation efficiency, pore structure and final leaching rate of granulated particles. Form effective guidance for on-site regulation

At present, most invention patents in the field of ore granulation focus on ore granulation under certain working conditions such as fixed inclination, fixed speed, or fixed inclination with adjustable speed, fixed speed with adjustable inclination, etc. In addition, the existing inclination adjustment is not accurate enough and The continuous adjustment of the inclination angle of the granulation device cannot be realized. At present, there is still a lack of research and development of multi-working-condition ore granulation devices and methods that are connected with industrial granulators, with continuously adjustable inclination angle and continuously adjustable speed. It is urgent to innovate ore granulation. Related devices and methods
