Screening&Classification

This section is important because it creates the natural transition to the conveying section: after briquetting or granulation, the product is screened, qualified material is conveyed onward, and off-spec fractions are recycled or reprocessed.

1. Product Description:
To complete the briquetting and granulating package, Huabang also supplies downstream vibratory screening systems for size classification, fines removal, and product finishing. In complete-line applications, the screening unit is typically installed immediately downstream of the briquetter or granulator to separate qualified product from oversize and fines before conveying and packaging.
2. Key features:
2.1 multi-deck screening arrangement

2.2 high screening efficiency for granules and briquettes

2.3 stainless-steel product-contact parts

2.4 enclosed operation for dust control

2.5 rapid screen change, typically within 3-5 minutes

2.6 single or multi-layer deck arrangement

3. System Integration

Huabang’s briquetting and granulating systems can be delivered as stand-alone machines or as complete downstream modules including:

3.1 feed hopper and metering equipment

3.2 dry roller briquetter or steel-belt granulator

3.3 hydraulic and local control system

3.4 vibratory screener

3.5 recycle and fines return logic

3.6 discharge conveyor

3.7 storage hopper and bagging interface

3.8 dust collection and local aspiration connections

This integrated approach allows the shaping section to function as a stable bridge between melt solidification or raw powder handling on the upstream side and conveying, storage and packaging on the downstream side.

Conveying Systems

The core conveying portfolio types

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 types

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 importan

This is particularly important in downstream systems handling:

flaked 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

Screw Conveyors and Screw Feeders

The core conveying portfolio types

Product Description

Screw conveying systems are among the most practical and widely used transfer methods for the enclosed movement of flakes, granules, and moderately free-flowing solids. They are particularly suitable for short- to medium transfer distances and for direct connections between process equipment such as flakers, hoppers, screeners, and bagging machines.

The system consists of a rotating screw inside a trough or tubular casing. As the screw rotates, the material is advanced along the conveyor axis and discharged at the outlet. The design can be adapted for horizontal, inclined, and selected short vertical duties, depending on product behavior and required feed stability.

Typical Applications

Screw conveyors are commonly selected for:

· flaker discharge to screening or intermediate collection

· hopper discharge to packaging systems

· transfer of granules to storage bins

· controlled metering into bagging or weighing equipment

· enclosed transfer where dust reduction is required

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
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
The same basic design can be used for either transfer or controlled feed. With appropriate speed control and screw geometry, the machine can provide relatively stable discharge into weighers, packaging machines, or secondary conveyors.

Adaptability to Product Condition
Pitch, shaft design, screw diameter, and casing geometry can be selected according to whether the product is flake-like, granular, warm, light-density, or somewhat cohesive.

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.

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 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
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
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.

Customization Options

Actual performance depends on product bulk density, bucket fill efficiency, lift height, and discharge behavior.

Available options include:

belt-type or chain-type arrangement
anti-backstop device
explosion relief and venting interface
inspection doors and maintenance platforms
wear-resistant boot section
level switch and blockage alarm
integrated inlet hopper and discharge chute design

Pneumatic Conveying Systems

Product Description

Key Technical Features

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.

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.For practical project use, conveying systems should be selected based on the duty rather than on machine category alone.

In numerous projects, an optimal solution often involves combining multiple conveyor types rather than relying on a single system. A typical configuration includes a screw conveyor for flaker discharge, a bucket elevator for product elevation, a belt conveyor for buffer transfer, and a screw or vibratory feeder for precise metered feed to packaging. This integrated approach enhances overall plant performance compared to using a single conveying principle throughout the process.
