Diatomite, also known as diatomaceous earth, is a naturally occurring soft siliceous sedimentary rock that is easily crumbled into a fine white or off-white powder. Because of its high porosity, low bulk density, and strong absorbency, diatomite is widely used in filtration, insulation, abrasives, and as a functional filler in chemical, food, beverage, and construction industries. However, its fine particle size, light weight, and abrasive nature make conventional material handling methods inefficient and dusty. Pneumatic conveying is the preferred solution for moving diatomite safely and reliably.

Our diatomite pneumatic conveying systems are designed to handle powders with particle sizes ranging from a few microns to several hundred microns, while maintaining consistent throughput and preventing material degradation. We offer both dilute phase and dense phase conveying options depending on your material characteristics, distance, and budget. Dilute phase conveying uses high-velocity air to suspend and transport diatomite through pipelines, making it suitable for short to medium distances and lower capital investment. Dense phase conveying operates at low velocity and high pressure, pushing material as a plug or fluidized bed, which reduces wear, minimizes particle breakage, and lowers energy consumption for long-distance or fragile applications.

Each system is custom engineered from the ground up. Our engineers evaluate your existing layout, required capacity, conveying distance, elevation changes, and the physical properties of your diatomite, including moisture content, particle size distribution, and bulk density. Based on this analysis, we design a complete solution that includes the correct blower or compressor, rotary airlock, pick-up adapter, conveying pipeline, diverter valves, receiver filters, storage silos, and PLC control system. Every component is selected for durability and compatibility with diatomite's abrasive and hygroscopic characteristics.

The main equipment in our diatomite conveying systems includes positive displacement blowers, rotary airlock feeders, venturi eductors, filter receivers, jet filter bags, and reverse pulse cleaning units. To minimize wear caused by abrasive diatomite particles, we use wear-resistant bends, ceramic-lined elbows, and thick-wall piping in high-velocity areas. Our systems are fully sealed to prevent dust emissions, meeting strict environmental and safety standards. We also provide optional nitrogen supply for inert conveying, grounding connections for explosion protection, and humidity control to avoid caking.

One of the key advantages of our custom diatomite pneumatic conveying solution is its flexibility. We can integrate multiple feed points and discharge points, allowing one central system to distribute diatomite to different processing lines, storage tanks, packaging machines, or blending units. The PLC-based control system automatically manages material flow, air pressure, valve sequencing, and filter cleaning cycles. Operators can monitor the entire process from a touch-screen interface or an integrated SCADA system, with real-time alarms and data logging for optimized operation and preventive maintenance.

Our solutions are widely used in brewery filtration processes, where diatomite is used as a filter aid; in the production of lightweight insulating bricks; as an absorbent for industrial spills; and as a carrier for catalysts and pesticides. In the food and beverage industry, our systems ensure hygienic, dust-free transfer of food-grade diatomite. In the construction industry, they handle large volumes of diatomite for cement, plaster, and roofing materials. We have successfully installed systems for mineral processing plants, chemical factories, and water treatment facilities, demonstrating our ability to adapt to diverse operational requirements.
