Self-powered sand and gravel separator

Application: Primarily used for de-dusting of sand and stone.

Key Advantages: Compact power configuration, eco-friendly, cost-effective investment.

Product Description:

The new sand and stone separation and dedusting process adopts a novel sand and stone dedusting machine with a dedicated electronic pulse dust collector for stone powder. This solution is a new type of sand and stone separation process. The new sand and stone dedusting machine is responsible for coarse and fine powder separation of the material, with the fineness of separation easily adjustable via a wind volume control valve. The separated stone powder is then carried by the air flow into a dedicated electronic pulse-jet pulse bag dust collector for stone powder, collected by the dust collector, and discharged into the atmosphere, fully meeting the specified 30mg/Nm³ standard.³Emission standards; Additionally, the system features no powered separator and no rotating parts, and all friction points with materials are made of imported wear-resistant steel plates, resulting in minimal wear on the equipment and easy maintenance; secondly, the system has low power consumption, with a low electricity consumption per unit product, approximately 40% less than traditional sorting processes.

Due to the vacuum operation of this equipment, no dust emissions are generated. It can also capture and process dust from the conveyor belt to meet emission standards. Additionally, the equipment is versatile in its layout and easy to install, requiring no extensive foundation for large-scale installations. The total height of the new sand and stone dedusting machine is only 2600mm, thus reducing the incline requirement for the belt conveyor.

Operating Principle

These devices combine the use of gravity, inertia, centrifugal force, and aerodynamics to process particles with sizes of 0-5mm Material grading is conducted between the levels. The feedstock and primary air enter the grading machine from top to bottom. The air flow changes direction. 120 Particles are graded by size and exit the classifier with fine particles carried away by the airflow. Coarse particles, which cannot be deflected by the airflow due to their own weight, fall to the bottom of the classifier and are then discharged through a valve. Secondary air is blown into the classifier from below the blades, forcing it through the curtain of falling particles. These coarse particles near the grading point are deflected by the secondary airflow and enter the vortex within the heart-shaped chamber. Fine particles captured upon entering the classifier and other particles pulled out from the vortex are: All are drawn into the collector (dust collector) by the exhaust air and then recycled post-processing. The secondary air throttle valve features a simple manual adjustment function, allowing for the change of the grading fineness of fine particles. Within the material flow range, there are no moving parts, resulting in low maintenance requirements. For abrasive materials, liners are used in certain areas to ensure a longer service life for the equipment.

Function: Sorting 0-5mm The dust content in the following materials can be controlled to be less than 1%。

1Easy adjustment; adjustment area provided. 4 Individual units for material waterfall control, primary air intake control, secondary air intake control, and air output volume control, allowing for easy adjustment of air volume and the finished product's powder content.

2Power-saving; the previous configuration scheme included a separator and dust removal system, but this model has no motor. The main power consumption is体现在 the dust collector, which allows for energy savings.

3Simple structure; minimal contact points with main materials, all wear areas are treated with Jiarend's proprietary wear-resistant process for reduced wear; maintenance-free with low maintenance costs.
