Beach placer is a common mineral resource, and its mining and utilization are of great significance for local economic development and environmental protection. However, due to the high amount of impurities in placer ore, gravity separation is required to improve the grade and utilization value of the ore. The seaside sand ore gravity separation equipment is designed to meet this demand. This article will provide a detailed introduction to the operating steps and usage precautions of the seaside sand ore gravity separation equipment.
1、 Equipment Introduction
The gravity separation equipment for seaside sand mines mainly includes vibrating screens, spiral classifiers, flotation machines, etc. These equipment can be combined and used according to the different characteristics and needs of the ore to achieve the best gravity separation effect. Among them, the vibrating screen is mainly used for preliminary screening, the spiral classifier is used for further classification, and the flotation machine is the final selection equipment.
2、 Operating Steps
1. Preliminary screening of ore
Firstly, the collected sand ore is fed into a vibrating screen for preliminary screening. The vibrating screen can separate ore according to different particle sizes, leaving large particles of ore on the screen, while small particles of ore fall into the hopper below through the sieve hole. The purpose of this step is to preliminarily classify the ore and prepare for subsequent classification and selection.
2. Further classification of ore
After preliminary screening, the ore needs to be further classified in order to improve its grade and utilization value. In this step, the spiral classifier plays a crucial role. A spiral classifier can classify ore according to different particle sizes, leaving larger particles inside the machine and smaller particles discharged through the outlet. The purpose of this step is to further improve the grade of the ore and prepare for subsequent selection.
3. Selection and treatment of ore
After the first two steps of processing, the grade of the ore has been greatly improved, but still needs to be cleaned to further improve the grade and utilization value of the ore. In this step, the flotation machine becomes the most important equipment. The flotation machine can mix the ore and reagent and then stir and blow to make the useful minerals in the ore float together with the foam, so as to achieve ore cleaning. The purpose of this step is to improve the grade and utilization value of the ore, making it more suitable for industrial production and market demand.
3、 Precautions for use
When using seaside sand ore gravity separation equipment, it is necessary to strictly follow the equipment manual and operating procedures to ensure the normal operation and effectiveness of the equipment.
When using vibrating screens and spiral classifiers, it is necessary to pay attention to the cleaning and replacement of the screen mesh and mesh to ensure the screening effect and equipment life.
When using a flotation machine, it is necessary to pay attention to the amount and quality of reagents input to ensure the beneficiation effect of the ore and the service life of the equipment.
4. In the maintenance and repair of equipment, it is necessary to pay attention to the cleanliness and lubrication of the equipment to ensure its normal operation and service life.
In short, the seaside placer ore gravity separation equipment is an important mineral resource mining and utilization equipment, and its operating steps and usage precautions need to be strictly followed to ensure the normal operation and effectiveness of the equipment. I hope this article is helpful for readers to understand the gravity separation equipment of coastal placers.
