◆ Product Introduction.

The strict classification of coarse and fine particles of silica sand or other minerals can be used instead of fine sieves to control the separation of minerals with poor specific gravity. Hindered Settlement Machine is a highly efficient equipment for fine-grained mineral classification. It mainly achieves accurate separation of materials of different particle sizes by regulating the gravity settling speed of water flow and material particles. The equipment is widely used in mining, metallurgy, the chemical industry, building materials, and other industries. It is especially suitable for fineness control and purification of non-metallic minerals such as quartz sand, kaolin, potassium feldspar, etc. Guote Company adopts advanced fluid mechanics principles and intelligent control systems to make the equipment run stably, energy-efficient and efficient, and with high classification accuracy, which can effectively improve product quality and resource utilization. It is one of the important classification equipment in the field of modern mineral processing.

◆ Advantage Features.

1. Under the action of rising water flow, the materials in the cylinder can achieve the purpose of particle size classification or specific gravity sorting, with high production efficiency and low energy consumption.
2. Equipped with an automatic control system, the grading granularity can be changed by adjusting the parameters of the automatic control system, which is easy to operate and control.
3. The water tank at the lower part of the cylinder is equipped with a special device, and the water supply hole is closed when the water is stopped, which prevents the material in the cylinder from blocking the water supply hole and entering the water tank.

◆ Working principle.

The working principle is based on the principle of restricted particle sedimentation. It achieves fine classification by regulating the difference in resistance encountered by particles when settling in dense media. The specific process is: the sand-water mixture enters the equipment cylinder through the feeding device from above and moves downward under the influence of gravity. A spray plate with uniform water distribution is provided at the bottom of the cylinder. Clean water is continuously injected from the bottom to form a water flow from bottom to top, which produces convection interference with the falling particles, thereby constructing a stable fluidized bed environment. In this fluidized layer, coarse or high-density particles gather downward due to their fast sedimentation speed, while fine or light particles are lifted by the water flow, realizing effective stratification and separation of particles. The equipment is equipped with a highly sensitive electronic pressure sensing system to monitor the pressure changes of the fluidized bed in real time and automatically adjust the opening of the bottom discharge mechanism, thereby achieving high-precision, stable, and reliable particle grading control.

◆ Successful Cases.

Hindered Settlement Machine is widely used in the field of fine classification of non-metallic minerals, especially for particle size control and impurity removal of minerals such as quartz sand, kaolin, potassium feldspar, barite, talc, feldspar, etc. In mining processing, it is used to improve the purity and fineness distribution uniformity of finished minerals; in the ceramic, glass, refractory and other industries, the restricted sedimentation technology can ensure that the particle size of the raw materials meets the process requirements, thereby improving product performance and appearance quality; in chemical powder processing, metallurgical auxiliary material preparation, etc., this equipment also has good application prospects. Due to its high classification accuracy, low energy consumption, and strong adaptability, it has become one of the important equipment for modern solid-liquid separation and particle fine screening.
