The fine sand recovery machine is a crucial piece of equipment in the modern mining and construction industries. It is also known as a fine sand extractor, fine sand collector, or fine sand recovery system. This advanced machinery is designed to recover fine sand particles from wastewater generated during the sand washing process, which are often lost in traditional systems.

Currently, most artificial sand production lines use wet processing technology, but this method has a significant drawback: the loss of fine sand particles below 0.2mm. In some cases, up to 20% of fine sand can be lost, which not only reduces production efficiency but also negatively affects the grading of the sand, leading to an unbalanced particle size distribution and an increased fineness modulus. This degradation in quality results in higher cement usage and increased costs when mixing concrete. Additionally, excessive fine sand discharge contributes to land resource waste and environmental pollution.

To address these challenges, our company has developed the YC series of fine sand recovery machines. These high-tech, environmentally friendly devices integrate advanced foreign technologies with practical on-site requirements, making them ideal for fine sand recovery applications.

In real-world applications, the fine sand recovery machine operates without requiring additional water consumption. It can extract over 85% of fine sand or ore that has been washed away from the original wastewater. The recovered material can be directly added to the finished product pile or stored separately as a high-grade material, significantly increasing the economic benefits for customers by more than 15%.

This equipment is widely used in various industries, including hydropower station sand and gravel processing, glass material processing, artificial sand production lines, coal preparation plant slime recovery, and environmental protection projects like mud purification. It effectively solves the issue of fine sand recovery within the production line.

The fine sand recovery machine consists of several key components: a motor, a vacuum high-pressure pump, a sediment separator, a TS dewatering screen, a cleaning tank, and a return box. Its working principle involves using a centrifugal slag pump to transport the sand-water mixture from the cleaning tank to the cyclone. The fine sand, separated by centrifugal classification, is then sent to the vibrating dewatering screen. After dewatering, the fine sand and water are effectively separated. A small portion of fine sand and mud returns to the return groove, re-entering the cleaning tank and cyclone. This cycle continues, ensuring efficient recovery and separation. When the liquid level in the cleaning tank becomes too high, excess water is discharged through the outlet. Adjustments such as changing the pump speed, modifying the mortar concentration, regulating the overflow water, and replacing the sand mouth help achieve the three functions of cleaning, dewatering, and grading.

Optical Fiber 2-color Ratio Pyrometer

This classification includes two color infrared pyrometers which consist of lens, fiber optics and processing components. Fiber optic can bear high temperature up to 250℃ and do not need additional cooling. It has strong casing, use stainless steel lens(with air purge functions), die cast aluminum housing, protection grade is IP54. SMART-F series two-color pyrometer determines the temperature of an object by measuring the ratio of energy at two different wavelengths. The advanced software and hardware design help pyrometers meet the application in harsh environment as moisture, dust, target size change, partial blockage and emissivity change, even if the detection signal attenuates 95%, the temperature measurement results will not be effected. SMART-F series two-color infrared pyrometer can meet the requirements of two color measuring in various industrial occasions. For example, medium-high temperature below 2000℃, such as: hot rolled plate, casting, cement kiln, heat treatment, induction heating, monocrystalline silicon and polycrystalline silicon, etc. It can also be used in ultra-high temperature below 3000℃ measuring with high stability, such as vacuum furnace, graphite furnace, high-temperature furnace etc. SMART-F series is not only suitable for general industrial occasions of temperature measurement, but also suitable for installation in occasions with strong electromagnetic interference and high environmental temperature.
