Working principle of quartz sand scrubbing machine
Quartz sand scrubbing machine is a commonly used pre-treatment and cleaning
equipment for quartz sand, widely used in quartz sand production lines. It is
mainly used to remove impurities such as soil, clay, and iron ore from quartz
sand, and improve the purity and quality of quartz sand. By combining with
water, the scrubbing machine can effectively remove impurities attached to the
surface of quartz sand, achieving the goal of improving material quality.
1. Overview of the Work Process
The working principle of the quartz sand scrubbing machine is based on the
combined action of friction, impact, and water flow. Inside the scrubbing
machine, quartz sand and water enter the equipment together and undergo intense
friction and stirring inside the cylinder. The water flow carries away
impurities, while the quartz sand is washed clean by friction and impact. The
entire process involves continuous movement to clean the surface of the
material.
2. Specific workflow
Feed: Quartz sand enters the scrubbing machine through a feeding device and
is usually mixed with a certain amount of water. Water can help reduce friction
between particles, lower the frictional resistance of materials, and facilitate
the dissolution and removal of impurities.
Material friction: The quartz sand and water that have just entered the
scrubbing machine will continuously rub against each other inside the equipment.
The inner cylinder of a scrubbing machine is usually a cylinder with a spiral or
reversing device. During rotation, quartz sand particles collide and rub against
each other inside the cylinder, effectively removing impurities such as soil and
clay attached to the surface of the particles.
Water flushing: The addition of water is a crucial step in the scrubbing
process. Water not only helps with the dispersion and flow of materials, but
also helps to remove impurities through the flushing effect of water flow. The
mixture of water flow and quartz sand can carry away the cleaned impurities
through the overflow port, ensuring that the material maintains a high level of
cleanliness during the cleaning process.
Discharge: After cleaning, the quartz sand is fully rubbed inside the
cylinder and discharged through the discharge port. At this point, most of the
impurities on the surface of the quartz sand have been removed, the sand
particles are purer, and the particle morphology remains relatively intact.
3. Key components of quartz sand scrubbing machine
Cylinder: The cylinder is the main working component of the scrubbing
machine, usually cylindrical or other suitable shapes. The material inside the
cylinder is constantly subjected to friction, and the structural design of the
scrubbing machine should ensure that the material can be evenly stirred and
rubbed.
Mixing device: The scrubbing machine is usually equipped with a set of mixing
devices (such as spiral blades or reverse impellers) inside to help evenly mix
quartz sand and water, and cause friction between sand particles to achieve
cleaning purposes.
Water source device: Water flow is a key factor in the cleaning process of
the scrubbing machine. In general, the design of a scrubbing machine includes a
water inlet, which controls the washing effect and cleanliness by adjusting the
water flow rate.
Discharge device: After cleaning, the quartz sand treated by the scrubbing
machine needs to be discharged through the discharge port. Usually, a certain
screen or filtration system is set up at the discharge port to ensure that the
relatively pure quartz sand can be discharged smoothly.
4. Scrubbing effect and influencing factors
The quality and flow rate of water: The flow rate and quality of water
directly affect the scrubbing effect. If the water quality is poor and
impurities are difficult to dissolve, it may affect the cleaning effect; If the
water flow is too small, the cleaning may not be thorough, and if it is too
large, it may waste resources.
Particle size of quartz sand: Coarse sand particles are difficult to clean
and may require longer friction to remove surface impurities; Fine particles are
easily cleaned by water flow, but they are also more susceptible to damage.
The working time and speed of the scrubbing machine: Appropriate working time
and speed can ensure sufficient cleaning of quartz sand and prevent particle
damage. Excessive scrubbing time may cause excessive friction of sand particles,
affecting the uniformity of particle size.
5. Advantages of quartz sand scrubbing machine
Efficient removal of impurities: Through the dual effects of friction and
water flow, various impurities attached to the surface of quartz sand, such as
clay and iron ore, can be efficiently removed.
Improving the purity of quartz sand: After cleaning, the impurity content of
quartz sand is significantly reduced, and the purity is improved, which is
beneficial for subsequent processing and application.
Energy saving and environmental protection: During the wet cleaning process,
not only can dust pollution be reduced, but water resources can also be
effectively utilized, which meets environmental protection requirements.
6. Common applications
Quartz sand production line: In the quartz sand production process, quartz
sand scrubbing machines are commonly used in the pre-treatment stage after sand
mining to help remove surface soil and other impurities, in order to obtain
higher purity quartz sand.
Building materials industry: In the production process of mortar and
concrete, scrubbing machines can effectively remove small impurities from sand
particles and improve the quality of sand materials.
Environmental treatment: In wastewater treatment and soil remediation,
scrubbing machines can also be used to remove pollutants and ensure the quality
of treated materials.
summary
The quartz sand scrubbing machine removes soil, clay, and other impurities
attached to the surface of quartz sand through the combined action of friction,
impact, and water flow, thereby improving the purity and quality of sand
particles. This equipment plays a particularly important role in quartz sand
production lines, as it can effectively improve product quality and enhance the
effectiveness of subsequent processing. During operation, adjustments need to be
made based on factors such as material particle size, water usage, and equipment
speed to ensure optimal cleaning results.
