Slag treatment and recycling equipment

With the continuous development of industry, the production of slag is also increasing. Slag refers to solid waste generated during smelting, smelting, roasting, processing, and other processes, containing a large amount of valuable metal components such as iron, copper, zinc, etc. Therefore, the treatment and recovery of slag is very important. This article will introduce the relevant knowledge and operating steps of slag treatment and recovery equipment.

1、 Types of slag treatment and recovery equipment

1. Magnetic separation equipment

Magnetic separation equipment is a commonly used equipment for slag treatment and recovery. It utilizes the magnetic differences of magnetic substances to separate slag containing metal components from waste slag. Magnetic separation equipment mainly includes magnetic separators, weak magnetic separators, high gradient magnetic separators, etc.

2. Re-selection equipment

Gravity separation equipment is a device that utilizes the difference in specific gravity of minerals in water for sorting. It mainly includes heavy medium sorting machines, spiral sorting machines, centrifugal sorting machines, etc. The re selection equipment is suitable for processing slag with larger particle sizes.

3. Flotation equipment

Flotation equipment is a device that utilizes the differences in hydrophilicity and hydrophobicity of minerals in water for sorting. It mainly includes air flotation separators, mechanical flotation machines, etc. Flotation equipment is suitable for processing slag with smaller particle sizes.

2、 Operation steps of slag treatment and recovery equipment

1. Operating steps of magnetic separation equipment

(1) The slag is roughly crushed and sent to the magnetic separator.

(2) The magnetic separator separates the slag containing metal components from the waste slag through magnetic substances.

(3) Send the separated metal containing slag into a weak magnetic separator or a high gradient magnetic separator for further processing.

(4) The treated metal containing slag can be directly used for production or processing.

2. Operation steps for reselecting devices

(1) After rough crushing, the slag is sent to the heavy medium separator.

(2) The heavy medium separator separates the metal containing slag from the waste slag through the difference in the specific gravity of water.

(3) Send the separated metal containing slag into a spiral or centrifugal separator for further processing.

(4) The treated metal containing slag can be directly used for production or processing.

3. Operation steps of flotation equipment

(1) After rough crushing, the slag is sent to the air flotation machine.

(2) The air flotation separator separates metal containing slag from the waste slag through the differences in the hydrophilicity and hydrophobicity of minerals in water.

(3) Send the separated metal containing slag into a mechanical flotation machine for further processing.

(4) The treated metal containing slag can be directly used for production or processing.

3、 Advantages of slag treatment and recovery equipment

1. Improve resource utilization
