Description

Kaolin Rotary Kiln Production Plant
Sentai Machinery designs and supplies a complete Kaolin Rotary Kiln Production Line for producing calcined kaolin (and, when required, metakaolin) used in ceramics, refractories, paint & coatings, rubber/plastics fillers, and cement-based materials. In kaolin calcination projects, customers typically focus on four practical issues: Stable product quality (whiteness / reactivity consistency) Fuel adaptability (depending on local energy supply and cost) Dust and emission control Reliable long-term operation with manageable maintenance To address these needs, our solution integrates raw material feeding (and size control if needed), drying/pre-drying options, sealed metered feeding, rotary kiln calcination, cooling, dust collection, and final product handling into one coordinated system. The process layout is customized according to your raw kaolin moisture, feed size distribution, target calcination requirement, and local environmental standards. As a project-type solution provider, Sentai Machinery can support you from process proposal and equipment selection to layout design, installation guidance, commissioning, and operator training. We also offer configurations aligned with international quality and safety expectations (e.g., ISO/CE-oriented manufacturing and documentation, depending on contract scope).

Features

Stable Calcination Quality for Industrial Minerals

Optimized kiln structure, refractory selection, and process control support consistent residence time and temperature stability—key to reliable calcined kaolin/metakaolin performance.

Flexible Fuel Options for Different Countries

The burner system can be configured for different fuel choices based on local availability and compliance needs (e.g., natural gas, diesel, or pulverized coal—subject to project design and regulations).

Turnkey Solution with Project Delivery Logic

From process design to layout guidance, installation/commissioning support, and training—our solution is built for customers who need an integrated production line, not just a single kiln.

Environmental & Safety Considerations

Sealed feeding/conveying plus dust collection (cyclone + pulse bag filter) helps reduce dust leakage and supports cleaner operation. Safety guards, emergency stops, and compliant electrical/control configurations can be applied per project scope.

Process Workflow

Stone Crushing Plant Flow Chart
Process Flow Diagram
1
Raw Material Feeding & Preparation

Kaolin is fed from hopper/feeder to the next stage. If your feed contains oversized lumps, a size-control step (crusher/screen) can be included to protect downstream equipment and improve kiln stability.

2
Drying / Pre-Drying (Optional, Based on Moisture)

For higher-moisture kaolin, a rotary dryer or pre-drying section reduces moisture, helping stabilize the kiln thermal balance and reduce fuel consumption.

3
Sealed Metered Feeding

A sealed and metered feeding system controls the feed rate, reduces air leakage, and supports stable kiln operation and dust control.

4
Rotary Kiln Calcination

Kaolin travels through the rotating kiln with controlled residence time and temperature profile to achieve the required phase transformation and product performance.

5
Cooling & Heat Utilization

The hot calcined product is cooled by a rotary cooler or other cooling solution. Heat utilization options can be considered to improve overall energy efficiency.

6
Dust Collection & Emission Control

Dust-laden gas is treated by a dust collection system (commonly cyclone + pulse bag filter). Additional measures can be integrated according to local standards and customer requirements.

7
Final Product Handling

The cooled product is conveyed to silo/bulk storage or packing system for shipment.

Note: Stcrushers can customize a set of Kaolin Rotary Kiln Production Plant according to customer's needs.

FAQ

A: Yes. The target product depends on the temperature profile and residence time. We recommend defining your end-use requirement first (e.g., ceramics vs. cement additive), then we configure the kiln and process accordingly.
A: Fuel selection depends on your country’s energy supply, cost, and compliance requirements. We can configure the system for different fuel options during project design and confirm details in the technical proposal.
A: A typical solution includes sealed feeding/conveying, controlled negative pressure, and cyclone + pulse bag filter dust collection. Additional configurations can be integrated based on local standards and customer requirements.
A: Please share (1) raw kaolin moisture range, (2) feed size condition (lumps or powder), (3) target product application/spec, (4) local fuel options, and (5) site conditions (available area, elevation limits). Then we can provide a process proposal and layout suggestion.
