1.Brief Introduction
Pulsating sluice box (also called vibrating sluice box) is a new type of gravity separation equipment designed for gold concentration, especially in alluvial gold recovery and tailings reprocessing.It was innovated by a Chinese engineer to replace traditional sluice boxes.
Key Features and Advantages
Enhanced Recovery: It significantly improves gold recovery rates, especially for fine particles, reaching 85%-90% recovery compared to conventional sluices.2
Pulsating Mechanism: The box incorporates a vibrating function that prevents clay deposition, allowing slower water speeds without requiring a steep slope. This helps fine and flake gold settle more effectively.
Higher Grade: It can increase the gold grade by about 10% compared to normal sluice boxes.
Technical Specifications
Capacity: 20-25 m³/hour
Power: 1.1 kW + 0.8 kW
Material: Carbon steel with fire-resistant features
Certification: ISO 9001:2008/2000
The pulsating sluice box is particularly effective in placer gold mining, where it optimizes the separation process by combining gravity and vibration.
2. Product Features
The pulsating sluice box solves the problems of raw ore hardening because the steel bar and holes on the grid from turbulence, which prolongs the time of gold separating from sand and stones. These creates good conditions for fine and flake gold.
It is the perfect combination of sluice and jigging machine for having both the advantages of big capacity of sluice chute and jigging characteristics of jigging machine.

4.Adjustment of flow and slope
The main information regarding the adjustment of water flow rate and slope in the pulsating sluice is as follows:
Water Flow Rate Adjustment:The water flow rate in the pulsating sluice needs to be adjusted according to the specific materials to be separated and the process requirements. Generally, the water flow rate directly affects the flow velocity of the slurry and the separation effect.
In actual operation, the water flow rate can be adjusted by controlling the output of the water supply valve or water pump to ensure that the slurry flows evenly and stably through the sluice to achieve the best separation effect.
Slope Adjustment:The slope of the sluice is one of the key parameters affecting the separation effect. The slope determines the flow velocity of the slurry and the separation efficiency.
Suitable Slope Range:The slope of the sluice is generally most suitable at 4% to 5%. If the terrain is relatively flat, the slope can be set above 1.7% to 2.1%, but it should be noted that a smaller slope may require a larger water volume to compensate.
Upper Limit of Slope:** The slope generally should not exceed 9% to 9.5%, as an excessively large slope can easily cause coarse gold particles to be washed away. Special Material Adjustments: For coarse sand, flat placer deposits, or placer layers containing a large amount of clay, a larger slope can be used. When washing mixed sand particles in a regular chute, if the water volume is constant, a flatter slope will result in higher work efficiency.
Comprehensive Adjustment Recommendations: When adjusting water flow and slope, a comprehensive consideration of the actual site conditions is necessary. It is recommended to first measure and analyze the slope, using a level or laser level to obtain the actual slope data, and then make fine adjustments based on the water flow velocity and material characteristics.
At the same time, regularly clean the silt and debris in the chute to ensure effective application after slope adjustment. We hope this information is helpful! If you have a more specific application scenario, please provide more details for further analysis.
