Limestone powder Flexible Screw Conveyor is a conveying system used to transport limestone powder from upstream equipment such as storage silos and grinding mills to downstream processes such as batching and molding. During operation, it solves the problems of powder scattering and clogging. Limestone powder has good flowability but is also prone to generating dust and has a certain degree of abrasion and hygroscopicity, making it easy to bridge or clump during transport, thus requiring high-performance conveyors. This type of conveyor typically covers a straight distance of approximately 10 to 20 meters from the inlet to the outlet, with the specific length varying depending on the plant layout.

For vertical conveying, the Limestone Powder Flexible Screw Conveyor can lift limestone powder from 1 to 6 meters, suitable for multi-story production needs. The equipment can transport from 500 kg to 10 tons per hour, adapting to various situations from small-scale trials to large-scale production. The feed inlet is typically equipped with a universal ball joint or flange connection, allowing direct connection to silos, mixers, or packaging machines. Material can be poured manually or via negative pressure suction. The discharge outlet uses a standard flange or flexible connection for easy connection to downstream equipment, ensuring smooth material discharge. Whether conveying horizontally, inclined, or vertically, the flow direction can be well controlled, reducing limestone powder leakage and dust scattering.

Limestone Powder Flexible Screw Conveyor Parts

The various components of the Limestone powder flexible screw conveyor determine its smooth operation. The screw blades are usually made of robust carbon steel or wear-resistant stainless steel with a polished surface, resulting in low friction during limestone powder flow and reducing the risk of damage. The screw itself acts like a flexible steel band, bending and weaving within the pipe to avoid obstacles while gently propelling the limestone powder without breaking it. The conveying pipe is made of strong, durable tubing, ensuring smooth powder flow and preventing breakage. The pipes are connected by clamps or flanges to prevent dust from escaping. The motor is installed at either the inlet or outlet end, with power ranging from 1.5 kW to 7.5 kW. It also features overload protection and speed regulation, allowing for speed adjustment based on limestone powder output and height during operation, ensuring smooth conveying.

Limestone Powder Flexible Screw Conveyor Performance

The Limestone powder Flexible Screw Conveyor demonstrates several advantages during use, particularly in terms of sealing, cleaning, explosion-proof design, and installation.

Its fully enclosed design effectively controls limestone powder within the tube, preventing spillage during conveying. This keeps the workshop clean and prevents external impurities from contaminating the powder, resulting in more consistent product quality.

Cleaning is also convenient. The flexible screw can be easily removed for cleaning without special tools, or the tube can be reversed to automatically remove residual powder. This is particularly useful for conveying food-grade or pharmaceutical-grade limestone powder.

Considering the potential fire hazard of limestone powder at certain concentrations in the air, this conveyor can be equipped with anti-static devices and explosion-proof motors. All metal parts are grounded, and explosion-proof sensors or nitrogen protection interfaces can be added as needed, making it suitable for high-risk environments.

Installation is also flexible. The compact, flexible spiral structure allows for bending, unlike traditional rigid conveyors that require straight tracks. It can be fixed to walls, ceilings, or placed directly on the ground, adapting to various complex factory layouts and reducing space occupation and modification costs, making equipment placement and adjustment easier.
