CHEMICAL AERATION ROUTE

NAAC block production line

HENGDE engineers NAAC block lines around chemical aeration and non-autoclaved curing. We connect material formulation, dosing, mixing, mould handling and cutting, backed by equipment experience at the Ordos and Jaiyl customer projects.

Delivery lead time: 40–50 working days.

Six route-specific process stages

  1. 01

    Prepare & meter

    Prepare the tested mineral and binder inputs, then meter powders and water.

  2. 02

    Chemical aeration & mixing

    Control aerating-agent dosage, mixing sequence and reaction conditions.

  3. 03

    Mix & pour

    Coordinate mixing and mould filling with the material expansion cycle.

  4. 04

    Non-autoclaved cure

    Cure without an autoclave under the project temperature and time controls.

  5. 05

    Demould & finish

    Release the billet at its handling strength and complete the selected cutting or finishing sequence.

  6. 06

    Handle & store

    Transfer and stack the blocks for continued curing and dispatch.

From local materials to an operating factory

HENGDE connects raw-material testing, factory planning, equipment manufacturing and site commissioning in one delivery plan. Our engineers develop the production route and machine interfaces, and our team prepares operators for production and maintenance. The proposal identifies the equipment, site preparation and services for your factory.

  1. 01

    Raw Material Testing

    Evaluate representative samples from the project location before selecting the final process.

  2. 02

    Formula Adjustment

    Adjust the formulation and material ratios against the test results and target product.

  3. 03

    Product & Process Selection

    Confirm product dimensions and the product-specific preparation, forming, curing and finishing process.

  4. 04

    Factory Layout Planning

    Coordinate land, buildings, storage, material flow, foundations and utilities.

  5. 05

    Production Line Customization

    Match capacity, automation, budget, moulds and process interfaces to the agreed factory scope.

  6. 06

    Equipment Manufacturing

    Prepare the agreed machines, tooling and controls against the approved configuration.

  7. 07

    Factory Acceptance

    Check applicable equipment and delivery scope before shipment.

  8. 08

    Packing & Shipping

    Coordinate packing, loading and destination requirements with the project shipping plan.

  9. 09

    Site Installation

    Install and connect the agreed equipment after site conditions are ready.

  10. 10

    Commissioning

    Check machine sequences and trial production with the selected materials.

  11. 11

    Operator Training

    Train operators in safe use, production sequence and routine maintenance.

  12. 12

    After-sales & Spare Parts

    Plan maintenance communication and spare-parts support for the installed equipment.

Local Raw Materials, Engineered into Your Production Plan

RAW MATERIAL OPTIONS

HENGDE NAAC lines use chemical aeration and non-autoclaved curing. Our engineers coordinate material preparation, reaction control, mould filling and curing around the tested formulation.

Test the NAAC material system

Review the confirmed cementitious and siliceous materials, water and project chemical-aeration input before equipment selection.

Lime, gypsum and aluminium powder are included only where the reviewed NAAC engineering route specifies them.

Tune chemical aeration after testing

Test results guide dosing, mixing sequence, temperature controls, mould filling and expansion behaviour.

Non-autoclaved curing, demoulding and finishing conditions are confirmed for the selected block and local materials.

CUTTING WASTE RECOVERY

Cutting Waste Settling & Recovery System

HENGDE plans collection, drainage and settling as a connected recovery loop. We size the recovery area and select pump and return-water arrangements around the cutting process, factory layout and material-test results.

  1. 01CuttingCollect cutting water and fine material at the cutting area.
  2. 02DrainageGuide the wet stream through a controlled drainage path.
  3. 03Recovery PitReceive the collected stream in an accessible recovery pit.
  4. 04SettlingAllow suspended solids to separate before water returns to the process-water system.
  5. 05Water ReuseReturn clarified water within the water-quality limits established for the mix.
  6. 06Suitable Fine Material ReuseMeter compatible recovered fines at the reuse rate established by material trials.
