The Differences of High-Quality Manufactured Sand and Common Manufactured Sand

Industry Background

Resource management: Natural sand is becoming scarce; Illegal mining and unauthorized digging are badly damaged the environment; the transport distance affects the cost; production mode is scattered and backward, lacking of overall long-term planning and basic requirements.

Product quality: product quality is not unstable; common manufactured sand is mainly made of stone-chip with coarse fineness; nature sand has fine fineness degree; while the clay content is over-proof; chloride ion content is over-proof in sea sand.

The Disadvantages of Common Manufactured Sand

Gradation is unreasonable
Fine content and clay content are over-proof
Lots of elongated and flaky particle

The Advantages of High-Quality Manufactured Sand

The shape like the cubic particle
Gradation is reasonable
Fine content is adjustable

High-Quality Manufactured Sand and Stone Making Station

SGL/SSL Series Sand Making Station

SGL/SSL series sand making station adopts the dry sand making process and floor layout. It contains six sections like feeding, sand processing, sand discharging, dust collecting, fine storage and electric controlling system. Sand processing is the core part of the production system. In this section, the raw material will be crushed, reshaped, then air classification and screening, gradation adjusting and moisture controlling. If the previous crushing section also adopts SANDMINE machines, this section will have a better performance. The main building covers a small floor space. The whole building can be covered with dust-proof and water-proof board. So, the production can start at any time without the influence of weather. At the same time, it will reduce the noise and dust pollution.

The Application of SGL/SSL Sand Making Station:

Commercial concrete, Dry mix mortar and construction waste recycling aggregate

Features of SGL/SSL Sand Making Station

SANDMINE adopts gradation adjustment technology solved the problem that the coarse and fine sand gradation is far larger than the median sand gradation in common manufactured sand. It is well controlled the coarse median and fine sand gradation achieved the national standard to meet the needs of various kinds of concrete and dry mixed mortar sand. The reasonable gradation of sand can reduce the interspaces between the aggregate and the cement consumption in concrete. Meanwhile, it can improve the compactness and durability of concrete.

Introduction of The Major Machines

Sand Making Machine

- Excellent cavity design, beside the blowing bars, there are alloy blades. Different impeller adapt to different working style.

- It adopts the oil lubrication of non-contact sealing. The running speed can reach 85m/s much higher than 70m/s as common.

- Sand making machine is places on the ground floor to reduce the total height of the station. And it will minimize the shaking to the station. So the whole station will be more safety and stability.

- It adopts the new impeller and alloy hammer, which is more wear resistant.
Vibrating Screen

- It adopts tri-axial elliptical screen and high frequency vibrating screen

- Fine particle grading is more accurate and efficient.

- It is anti blocking.

- The storage hopper is mobile one, which make the maintenance easy.
Air Grading System

The air grading system can separate the fine particle under 1.5mm from the crushed material to reduce the loading capacity of vibrating screen, which can increase the screen sieving capacity. The air grading system working together with dust filter can adjust the fine content in the final material.
Air Sorting System

The air sorting system can classify some dust from the fine particle under 1.5mm. So, it can reduce the dust filter’s workload.
Dust Filter

-Intelligent control: air pressure is automatically control. It is working together with air grading and air sorting system to reduce the workload and energy consumption. So, the dust filter can choose the small size.

-First classify the dust from the crushed material to reduce the screen load and increase the sieving efficiency.

Electronic belt scale: control the fine content for different application
Wet Mixing System

The wet mixing system make the water content qualified. So the fine particle and coarse sand can be uniform mixed without isolation.

The adaptive heating system keeps the dry saturated surface water content between 3-5% to make sure the uniform mixing.

This system is only applied for commercial concrete station, not for dry mix mortar
Monitoring System

Monitor the production status of the equipment in all directions; and carry out safety chain management.

If the abnormal situation occurs, it can accurately indicate the equipment fault location, reminding the staff to view and repair at the specified location to realize accurate fault location and investigation.

PLC intelligent operating system can save the human force and cost.
Automatic Control System

Each device is monitored in real time by sensors; and it can adjust the setting parameters digitally to meet the different requirements of fineness modulus and gradation of the manufactured sand.

The central controlling carries out digital management of each adjustable part of the system through an industrial computer which is the full interface operation, simple and efficient.

The system has a variety of preset modes to meet different requirements. In the other hand, it has the manual controlling mode to offer the custom-made solution.
Fine Particle Sorting System

The fine particle and dust will be classified before the material fed into the sand making machine.
Clay Removal System (Optional)

The clay will be separated before the material fed into the sand making machine.
Water Removal System (Optional)

The water removal system is an optional device to ensure the water content is adjustable.
