Jiuzhou Tianhe intelligent coal, ore and resource sorting

Jiuzhou Tianhe within Haiwang

Jiuzhou Tianhe (Shandong) Intelligent Technology, 九州天禾（山东）智能科技有限公司, develops intelligent sorting equipment, ash measurement instruments and software systems for coal, ore and resource recovery. Haiwang's official website presents the company among the group's subsidiary businesses.

Define the plant objective before selecting a sorter

Define the project objective: preliminary gangue removal, thermal or coking coal preparation, ore recovery or secondary resource separation. Include the process diagram and location of the new unit.

Describe required product quality and the destination of each stream: further processing, storage, recirculation or sale. This makes proposals comparable against the plant duty.

For upgrades, provide current picking arrangements, water use, downstream loading and quality issues. State actual feed rate, including shift and seasonal variations, and distinguish desired improvements from mandatory operating conditions.

Provide representative feed information

For coal, identify the product application, feed ash content, gangue proportion, moisture and particle size distribution. For ore, describe the mineral composition, valuable constituents and the main waste rock types. For secondary resources, list the mixture components and contamination.

Explain how the material changes between mining areas or incoming batches. Highlight sticky material, oversized foreign objects and fines generated during handling.

Photographs help describe the feeding conditions, while representative samples and measurements provide a firmer basis for technology selection.

Use information from several operating periods. An average sample and the most difficult feed serve different purposes: the first describes normal operation, while the second helps assess the operating envelope.

Record the origin, date, storage conditions and preparation method for each sample so that test results can be related to actual plant conditions.

Agree a practical test programme

Jiuzhou Tianhe operates a testing function for coal preparation and mineral processing. Define the programme before submitting material: which feed will be tested, which products are required and which indicators will be compared.

Proposed measurements can include useful product yield, composition, valuable material losses and mass distribution between streams. Discuss testing several batches and settings. After the trial, request input data, sample preparation details and results for each output.

This provides a useful basis for evaluating the proposed process on your feed.

Compare alternatives using the same sample preparation and analytical methods. Record operations performed before and after sorting.

If a test uses a screened fraction, assess the result for that specific stream; extending the conclusions to the entire mine production requires a separate technical agreement.

HX for coal preparation projects

The coal portfolio covers intelligent gangue removal, thermal coal upgrading and preliminary gangue rejection in coking coal preparation. When considering HX, describe the installation stage, required output streams and existing feed preparation. Specify where coal, gangue and fine material will go.

Agree the transport arrangement after the sorter. For a project processing material from several sources, show their differences and the planned operating sequence. These details support a coherent layout and a clear process duty.

When replacing manual picking, include the current working area and feeder conveyor arrangement. For a new installation, provide a layout and elevation plan.

The supplier needs to understand how the unit will operate within the line, including starting, stopping and clearing procedures and the allocation of responsibility for adjacent equipment.

HXR for ore and resource recovery

HXR combines material imaging, feature analysis and controlled pneumatic separation. List the valuable minerals and common waste rock types and provide information on crushing and screening before the unit. Describe which material should remain in the main stream and which should be diverted.

Define requirements for the subsequent processing of the separated products. For secondary feed, list the components to be recovered and contaminants that may vary between batches. The resulting enquiry links the machine duty to the whole processing route.

The test programme should consider heterogeneous samples and gradual feed changes. One favourable sample provides limited information about continuous plant operation.

Agree how results will be recorded and which criteria the plant technologist will use to accept the equipment after commissioning on the agreed feed.

Integrate feeding, compressed air and dust removal

The HXR feeding system distributes material using an inlet mechanism, vibrating screen and conveyor belt. Provide the upstream conveyor details, transfer point and available space for layout work. Identify service access and walkways.

The pneumatic execution system needs an agreed air source, while dust removal requires a defined connection to the site infrastructure. Discuss these conditions before finalising the equipment arrangement so that they are included in both the proposal and installation planning.

Request connection requirements, installation drawings and service points. Separate manufacturer equipment from site work such as foundations, cable routes, air piping and product discharge.

This division makes quotations comparable and allows the installation organisation to plan the tasks and interfaces before equipment arrives.

Select an ash measurement arrangement

Jiuzhou Tianhe offers K and Z online ash analysers. The K model is described for coal quality monitoring at mines, preparation plants, coking plants and other industrial sites. The Z model is described for operation with sampling equipment.

Start with the measurement point: incoming coal, an intermediate stream, finished product or material before blending. Provide the material transport and sampling arrangement and describe how the result will be transferred to the control system.

Explain the decisions operators will make from the measurement: adjust a blend, identify an off-specification batch or change an operating setting. Prepare the laboratory reference method and a comparison schedule for the agreed verification programme.

Include feed variability, routine servicing and the procedure for checking the measurement assembly in working conditions.

Connect the sorter to the plant control system

HXR provides local and remote control, status signals and industrial Ethernet. Before ordering, list the plant signals required for readiness, start permission, running, stop and fault. Discuss interlocks with feeding and product discharge.

For supervision, define the required operating data, retention period and display location. Treat video monitoring and belt speed measurement as parts of a coherent process observation arrangement. This helps operators understand the relationship between material presentation and sorting behaviour.

For integration into an existing line, include current electrical drawings and the automation team's requirements. Allocate responsibility for interface preparation, configuration and signal acceptance.

Verify the installation in stages: individual mechanisms, coordinated starting, material introduction and operation at the agreed settings.

Specify the supply package and acceptance

Separate the main sorter, feeding equipment, execution modules, measurement instruments and utility connections in the technical proposal. State the contents, documentation and supply boundary for each assembly.

Agree spare components for commissioning and routine maintenance, operator training and documents for the installation organisation. Transport planning needs package dimensions, weights and unloading conditions.

These details allow the site to prepare for delivery and reduce uncertainty when equipment and site work meet.

Write acceptance criteria before manufacture: equipment completeness, mechanical operation, signal exchange and process results on agreed feed. After commissioning, retain settings, drawings and the installed component list.

These records provide a reliable identification basis for later spare part enquiries and help keep maintenance requests consistent with the equipment actually in service.
