High Quality Double-impeller Leaching Tank for Carbon in Leaching Gold Extration

Energy efficiency agitator is a equipment used for gold cyanidation leaching process and absorption, two transmission ways, one is the planet-cycloid reducer drive; the other is the plane envelope reducer drive.

This equipment working conditions: pulp concentration ≤ 45%, pulp concentration ≤ 1.4 t / m.

The advantage of the device : (a) high gold recovery rate (b) adopt a planet-cycloid reducer or flat envelope Reducer drive, high-efficiency to 92%; (c) special structure compared with the same type equipment reducing the motor power, energy-saving rate 27.3%; (d) Little chance of accident happening, high overload capacity; (E) Light weight, low-cost, long service life; (f) low noise; (g) compact structure.

Equipment model in Table 1-1, according to the requirements of the user can produce a variety types of high-energy agitator.

Double impeller leaching tank (Figure 1) equipped with motor, cycloidal planetary gear speed reducer, bearing block and agitating shaft, is characterized by compact structure, little occupied space, and the agitating shaft equipped with a double impeller , from the top view the impeller rotating clockwise, each impeller composed of 4 blades, and the angle of the top blade and the below one is 45 degree. The compact air gets through the elbow pipe or the hollow shaft to the tank’s bottom, the raising air plays the role of mixing , at the same time the big bubble shattered by the impeller changing into small bubbles, in the end the pulp and air reaches fully mixing and sodium cyanide solution contacts with the pulp completely, thereby gets the better gold leaching result. The design of this device keeps the impeller low-speed moving, reducing the possibility of wearing or smashing the active carbon, so as to achieve high leaching rate, high absorption rate and collects more gold.

Agitator impeller driven by the motor, and pulp flow to tank’s bottom, in order to prevent bottom’s wear, base plate lined at the bottom to extend the service life.

1.The device is composed of two major components, during the installation which should be aligned to ensure the vertical axis and the reducer axis keep coaxially..

2.The installation of blades, each impeller’s 4 blades should be in symmetric position, the top and the below blade in 45°c, no tilting of the blade.

3.The foundation bolt should be fastened during the installation.

4.Make sure the fuel pumps works normally.

Usage

First check whether the reducer’s oil reaches the right position, whether there is leakage or debris in the tank, and whether the screw is fastened.

After checking all in position, fill the compact air, and there must be enough wind pressure to make the axis spin, now it rotating anticlockwise, under the influence of wind making pulp mixing evenly, and then start the motor, the axis rotates clockwise, when it operates normally feed the pulp, pulp concentration ≤ 45%.
