ZPC-12 Shearer Dust Suppression Spray System
The system uses an automatically water-level-controlled tank to supply water to a high-pressure pump station, which boosts the low-pressure water to over 12 MPa. This pressurized water is then thoroughly atomized through a customized dust suppression module and an ejector-type swirl-mist nozzle, creating a high-speed mist with droplet diameters smaller than 100 μm. This fine mist effectively envelops and covers all areas around the coal-cutting drum of the shearer during operation, ensuring comprehensive dust control and achieving highly efficient dust suppression.

Product Overview
The system uses an automatically water-level-controlled tank to supply water to a high-pressure pump station, which boosts the low-pressure water to over 12 MPa. The pressurized water is then thoroughly atomized through a customized dust suppression module and an ejector-type swirl-atomizing nozzle, creating a high-speed mist with droplet diameters smaller than 100 μm. This fine mist effectively envelops and covers all areas around the coal-cutting drum during the shearer’s operation, ensuring comprehensive dust control and achieving highly efficient dust reduction.
Product Features
● Customized design of spray modules tailored for different types of shearer machines, validated through computer-aided 3D simulations, ensuring precise, three-dimensional, and full-coverage high-pressure water mist around the shearer drum.
● Using a backwash filter to treat water quality allows it to adapt to various types of mine water conditions.
● Equipped with a stainless steel water tank, featuring automatic water level control and built-in protection against low-water and overflow conditions.
● The jet-type swirl atomizing nozzle produces fast-moving, fine droplets with a wide spray pattern, achieving dust suppression efficiency of over 60%.
