Liming Machinery at the 140th Canton Fair: Integrated Solutions for Cement Grinding, Lime Calcination, and Gypsum Processing

Booth Information

The 140th Canton Fair

Date: October 15-19,2026  

Add.: Pazhou Complex, Guangzhou, China

Hall: 20.1 Booth: J44

Liming Machinery will exhibit at the 140th Canton Fair (China Import and Export Fair), held from October 15 to November 4, 2026, in Guangzhou. The company will present its complete equipment portfolio for mineral processing, including vertical roller mills for cement and slag grinding, rotary kilns for lime calcination, and gypsum powder production lines.

What Liming Machinery Brings to Canton Fair

Liming Machinery manufactures complete equipment systems for cement plants, lime production lines, and gypsum processing. The company serves over 30,000 customers across 180 countries and holds more than 280 patents, with ISO9001, EU CE, and CU-TR certifications.

The equipment range covers:

Cement vertical mill systems for clinker and raw material grinding

Lime rotary kilns and vertical shaft kilns for limestone calcination

Gypsum calcination lines for natural gypsum and industrial by-product gypsum

Slag vertical mills for granulated blast furnace slag processing

Cement Vertical Mill: Key Specifications

The cement vertical mill system integrates crushing, grinding, drying, and classification in a single unit. For cement clinker grinding, power consumption is reduced by 15–20% per ton compared to traditional tube mills.

ParameterTypical Value

Capacity Range18–550 t/h (raw meal)

Finished FinenessSpecific surface area ~350 m²/kg

Noise Reduction15–20 dB lower than ball mills

System OperationFully sealed negative pressure

The LMR58-4 vertical mill, with a 5.8-meter grinding disc diameter, achieves raw material grinding capacity of 550 t/h, sufficient for a single unit to support large-scale production lines.

Lime Production Line: Process and Capacity

Liming Machinery’s lime production line uses the “preheater—rotary kiln—vertical cooler” process. Limestone with CaCO₃ content above 85% is calcined at 1100 ± 50°C.

Production capacities:

Lime rotary kiln: 200–1000 TPD

Lime shaft kiln: 100–800 TPD

Twin-shaft kiln: 150–800 TPD

The flue gas treatment system reduces dust emission concentration to below 30 mg/m³ through cyclone and bag filter stages. For the Philippine market, Liming Machinery supplied a 300,000 TPY lime production line combining LM vertical mill grinding with rotary kiln calcination. The finished lime achieved CaO content above 90% and activity above 300 mL, meeting local industrial specifications.

Gypsum Processing: Natural and By-Product Solutions

For gypsum processing, Liming Machinery offers vertical roller mills and complete calcination lines. The process handles both natural gypsum and industrial by-products including desulfurization gypsum, phosphogypsum, and titanium gypsum.

Calcination temperature control ranges from 190–800°C using fluidized bed furnaces or rotary kilns, ensuring uniform crystal transformation and stable product performance. The company’s experience in gypsum processing was recently presented at the 24th Global Gypsum Conference in Istanbul.

A Case Reference: Philippine Lime Project

A Philippine mineral processing company required 300,000 tons per year of active lime for the domestic industrial sector. Operating conditions included high humidity and monsoon rains, demanding equipment capable of processing limestone with elevated moisture content.

Liming Machinery supplied an integrated LM vertical mill and rotary kiln system. The LM mill’s built-in drying function eliminated separate drying equipment. Operational results included:

200-mesh limestone powder production without auxiliary dryers

Power savings of 8–12 kWh per ton compared to ball mill alternatives

Finished lime CaO >90%, activity >300 mL

Dust emissions below 10 mg/Nm³ via pulse bag filter system

2–3 operators sufficient for the entire grinding line
