Binhai Sand Mine Beneficiation Production Line

As an important mineral resource, sand mining has extensive applications in fields such as construction, roads and bridges, and water conservancy. As one type of coastal sand mine, its mining and beneficiation processes are different from inland sand mines. This article will introduce the process flow and operating steps of the seaside sand ore beneficiation production line.

1、 Process flow of the beneficiation production line for seaside sand mines

The process flow of the seaside sand ore beneficiation production line mainly includes raw ore screening, washing, grinding, gravity separation, and selection.

1. Raw ore screening

After the raw ore is collected and transported, it first needs to be screened. The purpose of screening is to divide the raw ore into particles of different particle sizes for subsequent processing. In the beneficiation production line of coastal sand mines, vibrating and rotating screens are usually used for raw ore screening.

2. Washing

After screening the raw ore, washing is required. The purpose of washing is to remove soil, impurities, and organic matter from the raw ore for subsequent grinding and gravity separation. In the beneficiation production line of coastal sand mines, water washing machines are usually used for washing.

3. Grinding

The washed raw ore needs to be ground. The purpose of grinding is to refine the mineral particles in the raw ore for subsequent gravity and selection. In the beneficiation production line of seaside sand mines, ball mills are usually used for grinding.

4. Reselection

After grinding, gravity separation is required. The purpose of re selection is to separate mineral particles according to their density for subsequent selection. In the beneficiation production line of coastal sand mines, a heavy medium separator is usually used for gravity separation.

5. Selection

After re selection, a selection is required. The purpose of selection is to separate mineral particles according to their grade for subsequent processing and utilization. In the beneficiation production line of coastal sand mines, flotation machines are usually used for beneficiation.

2、 Operation steps of the beneficiation production line of Haibin Sand Mine

1. Operating steps for raw ore screening

(1) Place the raw ore into a vibrating or rotating screen;

(2) Open the vibrating or rotating screen to pass the raw ore through the screen;

(3) Classify the screened mineral particles according to their particle size.

2. Washing operation steps

(1) Put the screened raw ore into a water washing machine;

(2) Turn on the washing machine and mix the water flow with the raw ore;

(3) Put the washed raw ore into the grinding machine.

3. Grinding operation steps

(1) Place the washed raw ore into a ball mill;

(2) Turn on the ball mill to refine the raw ore particles;

(3) Place the ground raw ore into the heavy medium separator.

4. Steps for reselection operation

(1) Place the ground raw ore into a heavy medium separator;

(2) Start the heavy medium sorting machine and sort according to the density of mineral particles;

(3) Place the re selected mineral particles into the flotation machine.

5. Selected operation steps

(1) Place the re selected mineral particles into the flotation machine;

(2) Start the flotation machine and sort according to the grade of mineral particles;

(3) Package and transport the selected mineral particles.

III. Summary

The seaside sand ore beneficiation production line is an important mineral resource processing equipment, and its process includes raw ore screening, washing, grinding, gravity separation, and selection. During the operation process, it is necessary to operate according to the process flow to ensure the grade and quality of mineral particles.
