Flexible Screw Conveyor For Calcium Carbonate Powder

Saturday February-28 2026  17:34:07

Flexible Screw Conveyor For Calcium Carbonate Powder is designed for the closed-loop conveying of calcium carbonate powder, making it suitable for lightweight, dusty, and highly free-flowing powders. It is used in the feeding, transfer, batching, and metering of calcium carbonate powder, and can convey materials along horizontal, inclined, vertical, and even curved routes without any dust leakage.

The conveying pipe of the Flexible Screw Conveyor for Calcium Carbonate Powder is made of wear-resistant polyurethane or 304 stainless steel, while the spiral blades are made of 65Mn spring steel or stainless steel. The joints and hopper are also mostly made of stainless steel, ensuring both durability and hygiene. Common models include FX-75, FX-100, FX-125, and FX-160, corresponding to pipe diameters of 75mm, 100mm, 125mm, and 160mm, respectively. The conveyor length is customizable, typically ranging from 2 to 15 meters, with up to 20 meters available for special applications. The hourly conveying capacity ranges from 2 to 15 tons, and the motor power is 0.75–4kW, selectable based on pipe diameter and distance. Various installation methods are available: floor-mounted, wall-mounted, directly connected to equipment, or mobile with casters, facilitating connection to silos, mixers, packaging machines, and other equipment.

How does the Flexible Screw Conveyor for Calcium Carbonate Powder work?

After startup, the motor drives the internal flexible screw shaft to rotate continuously via a reduction gear mechanism. Powder falls naturally from the feed hopper into the sealed conveying pipe. As the screw blades rotate, the material is gradually propelled forward by the axial thrust generated by the blades and the friction between the blades and the pipe wall. Because the screw shaft has a certain degree of elasticity, it can bend with the pipe, maintaining stable conveying even with changes in direction, without affecting the rotation. The entire process does not rely on airflow; the powder moves in a closed environment, minimizing dust generation or stratification.

What are the advantages of a Flexible Screw Conveyor for Calcium Carbonate Powder?

The Flexible Screw Conveyor for Calcium Carbonate Powder features a fully enclosed structure for conveying calcium carbonate powder. This minimizes dust generation during material movement within the pipe, resulting in a cleaner workshop and reduced cleaning workload. It also eliminates the need for complex dust collection systems, reducing equipment investment and subsequent management pressure. Its layout is flexible; the pipe can bend or detour according to site conditions, adjusting to obstacles such as equipment and beams. It can be easily installed even in workshops with limited space, without major structural alterations. Structurally, it primarily consists of a screw and drive mechanism, with few components. Operation is smooth and quiet, requiring only simple routine checks and lubrication, making maintenance time-saving and labor-saving. The relatively gentle conveying process has minimal impact on the particle size and whiteness of the calcium carbonate powder, and it is less prone to impurities, making it suitable for production lines in industries such as coatings, plastics, and papermaking where raw material requirements are high. In addition, it can be connected to batching, metering, and packaging equipment to form a continuous operation process, ensuring smooth operation of the entire production line.

How much does the Flexible Screw Conveyor for Calcium Carbonate Powder cost?

The price of the Flexible Screw Conveyor for Calcium Carbonate Powder varies depending on the pipe diameter, conveyor length, material selection, whether it has variable frequency speed control, and the hourly conveying capacity. For example, the basic FX-75 model, with a length of 2–4 meters, features a carbon steel frame and polyurethane tubing, suitable for small-volume workshops, and costs approximately $1200–$1800. Commonly used models like the FX-100 or FX-125, with lengths of 3–8 meters, have stainless steel material contact parts and a wear-resistant spiral for smoother conveying, and generally cost $1800–$3500. The FX-160 long-distance model, 8–15 meters, features an all-stainless steel structure and offers optional explosion-proof motors and frequency converters, costing $3600–$6200. Customization requirements, such as extra-long or high-temperature resistant models, will increase the price.

Flexible Screw Conveyor for Calcium Carbonate Powder Installation Solution

The installation process for the Flexible Screw Conveyor for Calcium Carbonate Powder is simple: just follow the steps. First, verify the quantity and model of the parts, clear away debris from the ground, and ensure the foundation is level. Prepare tools such as a level, wrench, and sealant. Next, fix the support frame according to the conveying route, securing it with anchor bolts or expansion bolts. Use a level to correct the tilt angle and ensure the machine is stable. Then, connect the feed hopper, conveying pipe, and discharge port in sequence, adding sealing gaskets between flanges. Bend the pipes naturally, avoiding sharp bends. When installing the motor and gearbox, ensure coaxial alignment and follow the wiring instructions. During the commissioning phase, run the machine idle first, then add a small amount of material to observe its operation. Once smooth operation is confirmed, it can be put into use.

The Flexible Screw Conveyor for Calcium Carbonate Powder can be arranged horizontally, inclined, or vertically according to the workshop layout. It is also convenient for bending and turning, requiring no major site modifications during installation. During conveying, the material moves within a closed pipe, minimizing dust leakage, resulting in a cleaner workshop environment and reduced cleaning burden. The flexible screw operates smoothly, causing minimal damage to powder particles. Routine maintenance only requires periodic checks of the motor and bearings, making it easy for operators to learn. The equipment's conveying distance and output can be customized according to actual working conditions. It is suitable for calcium carbonate processing plants, plastic masterbatch workshops, coating production lines, paper mill batching systems, and powder storage and packaging processes. It can be integrated into existing production processes, helping companies reduce labor intensity and operating expenses.
