Conveying Systems

Section Overview

Tianjin Huabang supplies conveying systems as part of an integrated downstream solids-handling platform for flakes, granules, and moderately free-flowing powders. These systems are engineered to connect flaking, screening, storage, and packaging in a stable, low-loss, and plant-friendly manner. The conveying portfolio is intended for continuous industrial duty in chemical and related process industries, with emphasis on controlled transfer, enclosed operation, equipment compatibility, and straightforward integration into automated production lines.

In practical project execution, conveying equipment is not selected as an isolated utility. It is selected as a process link that must match the material form, conveying distance, required elevation, dust-control philosophy, plant layout, and downstream feeding precision. For this reason, Huabang organizes its conveying solutions into several complementary equipment families rather than promoting a single universal design.

The core conveying portfolio includes

Screw Conveyors and Screw Feeders

For horizontal, inclined, or short vertical transfer of flakes, granules, and moderately free-flowing solids, with good enclosure and strong adaptability to process interfaces

Bucket Elevators

Screw Conveyors and Screw Feeders

For efficient vertical lifting in limited floor space and for stable transfer to higher storage or packaging points

Belt Conveyors and Belt Feeders

Screw Conveyors and Screw Feeders

Belt Conveyors and Belt Feeders

For gentle transfer over medium distances, especially where product degradation must be minimized, and stable continuous flow is important

Vibratory Conveyors

Pneumatic Conveying Systems

Belt Conveyors and Belt Feeders

For controlled transfer, spreading, and gentle movement of solids, particularly useful where low material breakage and clean discharge are important

Pneumatic Conveying Systems

For enclosed transfer of granules and selected powders over longer distances, especially where dust control, routing flexibility, or plant cleanliness is a priority

Product Positioning and Engineering Approach

Huabang conveying systems are designed for industrial production environments in which reliability, containment, and maintainability are as important as nominal throughput. The engineering focus is not only on moving the product, but on preserving product quality and ensuring stable operation of the full line

This is particularly important in downstream systems handling:

laked products that must not be excessively broken
granules that must remain free-flowing
materials that may produce nuisance dust
heated or recently solidified products that require controlled handling
chemical products that demand corrosion resistance or enclosed transfer

Conveying-system design is developed around five practical e

Material Form

Layout and Distance

Material Form

Flakes, granules, and moderately free-flowing powders do not behave in the same way. Product geometry determines the most suitable conveying principle, the internal clearances, transfer points, and anti-bridging measures

Process Duty

Layout and Distance

Material Form

Conveying may serve simple transfer, controlled feeding, elevation, buffering, or line balancing. The selected machine must therefore match not only capacity, but also the role it plays in the process

Layout and Distance

Containment Requirement

Short transfer between connected equipment may favor screw or vibratory designs, while longer or more complex routing may justify belt or pneumatic systems

Containment Requirement

Where dust control, odor control, or enclosed operation is required, the conveyor must support sealed interfaces and easy integration with local exhaust or dust-collection systems

Downstream Stability

Containment Requirement

Downstream Stability

Packaging lines, screening systems, and storage hoppers all depend on consistent feed. Conveyors must therefore deliver stable, non-pulsing product flow within the required capacity window

Key Technical Features

Compact and Enclosed Construction

Screw conveyors provide a compact mechanical layout and are well-suited to installation beneath flakers, bins, and hoppers. The enclosed casing helps reduce product loss, dust escape, and environmental contamination

Strong Process Integration

Compact and Enclosed Construction

Because the inlet and outlet arrangement can be adapted easily, screw conveyors are effective as direct interconnecting equipment between upstream and downstream machines. This makes them particularly useful in packaged skid systems and compact plant layouts

Flexible Feeding Characteristics

Bucket Elevators

Product Description

Bucket elevators are used where material must be lifted vertically with high efficiency and minimal floor space. They are especially suitable for transferring flakes or granules from lower process elevations to storage bins, buffer hoppers, or packaging floors.

Material is loaded into a series of buckets attached to a belt or chain. The bu

Material is loaded into a series of buckets attached to a belt or chain. The buckets travel upward within an enclosed casing and discharge the material at the top through centrifugal or gravity-type unloading, depending on product behavior and system design.

Typical Applications

Bucket elevators are commonly used for:

lifting flaked product to storage silos or day bins
feeding elevated screening or packaging stations
vertical transfer in multi-floor process buildings
space-efficient integration into compact production layouts

Key Technical Features

Efficient Vertical Transfer

Good Capacity-to-Footprint Ratio

Bucket elevators provide a large vertical lift within a small footprint, making them well-suited to plants where horizontal space is limited

Good Capacity-to-Footprint Ratio

Compared with inclined conveyors that occupy large floor space, the bucket elevator offers a cleaner, more compact route for product elevation

Enclosed Product Path

Configurable Bucket and Discharge Design

The closed casing supports cleaner handling and reduced material loss. It also makes integration with dust control easier in areas where product fines may be present

Configurable Bucket and Discharge Design

Bucket shape, spacing, and discharge arrangement can be selected to suit flakes, granules, or other bulk solids, reducing material hang-up and improving discharge stability

Bucket Elevator Selection Table

Common design basis for the series

In a belt conveyor, the product travels on a continuously moving belt supported by rollers or a slider bed. Because the product rests on the belt rather than being mechanically pushed or agitated, this conveying principle is well-suited to applications where product preservation and clean discharge are important.

Typical Applications

Belt conveyors are commonly used for:

transfer of flaked product to screening or packaging
gentle movement of the finished product to storage
horizontal or mildly inclined transport between process areas
discharge from the breaker, screener, or inspection station

Vibratory Conveyors

Product Description

Vibratory conveyors provide controlled movement of solids through vibration rather than continuous dragging or pushing by a mechanical element. They are especially suitable for applications where gentle handling, controlled spread, and clean discharge are required.

The conveyor tray is excited by a vibratory drive, causing the product to a

The conveyor tray is excited by a vibratory drive, causing the product to advance in small repeated movements. Because the product is moved in a shallow bed with limited mechanical compression, this method can be beneficial for fragile flakes or for controlled product distribution ahead of screening or packaging.

Typical Applications

Vibratory conveyors are commonly used for:

flake discharge and spreading
transfer to screeners or inspection points
controlled feeding to packaging or accumulation hoppers
low-breakage movement of fragile products

Key Technical Features

Gentle Product Transport

Good for Controlled Distribution

The shallow-bed transport mechanism can reduce product degradation compared with more aggressive conveying methods

Good for Controlled Distribution

Vibratory conveyors are useful when the product needs to be spread evenly before entering another machine

Compact and Clean Design

Simple Mechanical Principle

The equipment can be built in a relatively compact format and is easy to integrate into enclosed or semi-enclosed process arrangements

Simple Mechanical Principle

With fewer moving internal contact components than some other conveyor types, the vibratory conveyor can provide reliable service within its proper duty range

Pneumatic Conveying Systems

Product Description

Pneumatic conveying systems are used where enclosed transfer over longer distances is required, or where the routing flexibility of pipework offers a strong plant-layout advantage. These systems are generally applied to granules and selected powders rather than fragile flakes, unless the product can tolerate the conveying conditions.

Mater

Material is introduced into an air stream and conveyed through a pipeline to the receiving point. Depending on product characteristics and process requirements, the system may be designed as a dilute-phase or denser, lower-velocity transfer.

Typical Applications

Pneumatic systems are commonly used for:

transfer of granules to storage or packaging zones
enclosed movement of selected powders
routing through congested or multi-level plant areas
dust-controlled transfer where open conveyors are undesirable

Key Technical Features

Highly Enclosed Transfer Path

The pipeline system provides robust containment and helps reduce dust emissions into the plant environment

Flexible Routing

Highly Enclosed Transfer Path

Pipelines can be routed around structural and layout constraints more easily than many mechanical conveyors

Clean Plant Integration

Configurable Receiving and Filtering

Pneumatic systems are suitable where material transfer must be combined with tidy plant layout and minimal open handling

Configurable Receiving and Filtering

The system may include filters, receivers, rotary valves, and air-material separation arrangements, depending on the product and duty

Pneumatic Conveying Selection Table

Common design basis for the series

Execution: pressure or vacuum conveying
Material form: granules and selected powders
Construction: carbon steel or stainless steel pipeline and receiver

Actual performance depends on particle size, density, friability, line routing, conveying pressure, and air-to-solids ratio
