Ore granulating device with adjustable inclination angle and adjustable rotating speed, and method

Abstract

The invention provides an ore granulation device with an adjustable inclination angle and an adjustable rotation speed, and a method, and belongs to the technical field of metal ore granulation. The device comprises a granulating drum, a partition plate, a fixed knob, a trapezoidal keel, a rotary supporting platform, an angle ruler, an angle adjusting bracket, an angle adjusting knob, a threaded lead screw, a driving rotating roller, a driven rotating roller, a variable speed motor, a motor bracket, a transmission device, a stainless steel bracket, a leveling nut and the like, wherein the angle adjusting knob on the threaded lead screw rotates to open and close the angle adjusting bracket, the current inclination angle is observed and determined by using the angle scale so as to achieve the adjustable inclination angle of the granulating drum, the variable speed motor is connected with a transverse supporting roller through a transmission system and drives the granulating drum to rotate, a keel is arranged in the granulating drum so as to improve the granule rolling granulating efficiency, and an axial supporting roller is arranged in a rolling guide rail so as to guarantee that axial displacement does not occur in the rotating process of the granulating drum. According to the invention, the device is simple in structure, the method is practical and convenient, and efficient ore granulation under the actual working conditions of different inclination angles, different rotating speeds and the like can be carried out.

Description

Technical field [0001] The invention relates to the technical field of metal ore granulation, in particular to an ore granulating device and method with adjustable inclination and rotational speed. Background technique [0002] my country is a major producer and demander of metal mineral resources, and has been the world's largest country in terms of metal mineral resource imports and finished metal output for 14 consecutive years. However, my country's metal mineral resources have poor endowment, complex mineral composition, and serious secondary incidents. Conventional mining and dressing methods have problems such as high cost and low efficiency, and it is difficult to meet the needs of my country's metal minerals. The use of ore heap leaching technology can effectively improve the efficiency of ore leaching and the recovery of valuable metal resources. However, for the heap leaching of fine ore and precious metal ore with high argillaceous content, such as: high-clay copper ...

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
