Solution for Screw conveyor

Solution for Screw Conveyor

The screw conveyor is a core equipment for powder conveying in concrete mixing plants. It conveys powders such as cement and fly ash by the rotation of spiral blades.

Basic Introduction and Application Scenarios

It conveys powders such as cement and fly ash by the rotation of spiral blades. It is suitable for scenarios like powder transfer between silos and feeding for batching systems in mixing plants, capable of horizontal or inclined conveying. It meets the demand for closed conveying, avoiding powder leakage and ensuring a clean production environment.

Advantage

Efficient conveying
Closed dust-proof
Compact structure
Strong adaptability

Solution for Powder Butterfly Valve

Analysis of Common Problems

Powder blockage in the trough:
High powder humidity or excessive feeding speed easily causes powder accumulation and blockage in the trough, leading to conveying interruption, even damage to spiral blades, and affecting the feeding rhythm of the mixing plant.

Severe blade wear:
Long-term conveying of powders containing impurities makes spiral blades easy to wear and thin, reducing conveying efficiency. It may also cause equipment vibration and abnormal noise due to blade deformation.
Overall Solutions

Control powder humidity and feeding speed:
Dry high-humidity powders in advance and install feeding flow valves to control the speed; clean residual powders in the trough after daily shutdown to prevent accumulation and blockage.

Regular inspection and blade replacement:
Inspect blade wear weekly, and repair slightly worn parts by welding; replace with new blades in time when wear exceeds 30% to ensure conveying efficiency.

Technical Characteristics Support for Accessories

Wear-resistant spiral blades:

Made of high manganese steel, they have high hardness and strong wear resistance, suitable for conveying various powders, extending blade service life and reducing replacement frequency.
Sealing and dust-proof kit:

Including trough end cover gaskets, bearing dust covers, etc., it enhances equipment sealing, prevents powder leakage and dust from entering bearings, and ensures stable operation.
Frequency conversion drive device:

It can accurately adjust the conveying speed to adapt to different powder characteristics and feeding needs, avoiding blockage caused by improper speed and reducing energy consumption at the same time.

Customer Case

An employee at a U.S. factory

USA

"After our baghouse dust collector ran for two weeks, the pressure difference was only 0.75 inches. This system has made everyone's work environment happier and healthier, and its performance exceeded my expectations."

A maintenance staff member at a Canadian enterprise

Canada

"The maintenance team can easily take care of this dust collection chamber because all components are easy to operate. We have been running it for over two years without any maintenance issues, and we are still using the original bag filters."

A U.K. manufacturing company

U.K.

"When our high-efficiency dust collector is in operation, the pressure difference of the filter is less than 1.5 inches of water column, which has helped us significantly reduce dust in the factory."

An Australian mining enterprise

Australia

"We installed this dust collector in 1989 to collect gypsum dust, and it has operated more reliably than other dust collectors."
