Dry grinding tables and wet grinding tables differ significantly in terms of structural principles, application scenarios, safety, environmental impact, and maintenance costs. The details are as follows:
I. Structure and Working Principles
1. Dry Grinding Table
(1) Structure: Primarily consists of a dust extraction hood, a fan, a filtration unit (such as filter cartridges or bags), and a dust collection bin;
(2) Principle: The fan generates negative pressure to draw grinding dust into the collection bin; the dust is captured by the filtration unit, and clean air is exhausted;
(3) Characteristics: No liquid is involved; dust is separated directly through physical filtration.
2. Wet Grinding Table
(1) Structure: Includes a housing unit, water pump, spray system, water circulation system, and sedimentation tank;
(2) Principle: A water pump sprays water onto the grinding area; dust mixes with the water to form sludge, which is then separated via the sedimentation tank or a filter screen, while clean air is exhausted;
(3) Characteristics: Uses a liquid medium (water) to capture dust, resulting in wet sedimentation.
3.Application Scenarios
1. Dry Grinding Tables
(1) Suitable materials: Non-flammable and non-explosive materials such as metal, wood, and plastic;
(2) Suitable industries: Humidity-sensitive sectors such as electronics, precision machinery, and furniture manufacturing;
(3) Characteristics: Suitable for dry environments; prevents liquid-induced damage to workpieces or equipment.
2. Wet Grinding Tables
(1) Suitable materials: Flammable or explosive dust (e.g., aluminum or magnesium powder) or environments with high dust concentrations;
(2) Suitable industries: Sectors prone to generating explosive dust, such as metallurgy, chemical processing, and stone processing;
(3) Characteristics: Uses a liquid medium to reduce the risk of dust explosions; suitable for high-risk environments.
