Roasted Bentonite Manufacturers in India | HTMC Group

In industrial minerals, bentonite holds a special place for its binding, swelling, and absorbent properties. When processed through controlled thermal treatment, it becomes roasted bentonite—a refined version that offers greater strength, purity, and heat resistance. In India, the demand for roasted bentonite has surged due to its extensive use in steel, foundry, and construction sectors. Among the prominent producers, HTMC Group has emerged as one of the most reliable Roasted Bentonite Manufacturers in India, known for its precision processing, consistent quality, and customer-centric approach.

What is Roasted Bentonite?

Roasted bentonite is produced by heating natural bentonite clay under controlled conditions, removing impurities and moisture to enhance its performance properties. The process improves the mineral’s binding strength, reduces impurities, and increases thermal stability—making it ideal for high-temperature applications.

Key characteristics of roasted bentonite include:

• Superior binding strength.

• Excellent thermal and structural stability.

• Low moisture content and controlled swelling.

• Enhanced mechanical strength and uniform particle distribution.

These qualities make roasted bentonite an essential component across industries such as iron ore pelletization, foundry casting, and construction.

Applications of Roasted Bentonite

1. Steel Industry (Iron Ore Pelletization)

One of the largest consumers of roasted bentonite is the steel industry, where it acts as a crucial binder during iron ore pelletization. The bentonite helps agglomerate fine iron ore particles into uniform pellets with sufficient mechanical strength for furnace processing.

HTMC Group, among the leading Roasted Bentonite Manufacturers in India, produces roasted bentonite grades specifically formulated for steel pellet plants.

Benefits of using HTMC Group roasted bentonite in pelletization:

• High green and fired pellet strength.

• Reduced breakage during handling and transport.

• Better sintering efficiency and metallurgical properties.

• Lower fuel consumption and energy cost.

This makes HTMC Group’s roasted bentonite a preferred choice for major steel producers across India.

2. Foundry Industry

In foundries, roasted bentonite is used as a binding material for molding sand in the casting process. It provides cohesion, mold strength, and thermal resistance, which are essential for achieving high-quality metal castings.

HTMC Group’s foundry-grade roasted bentonite ensures:

• Superior mold strength and stability.

• High thermal endurance for ferrous and non-ferrous castings.

• Excellent surface finish and dimensional accuracy.

• Easy mold collapsibility and sand reusability.

As one of the reputed Roasted Bentonite Manufacturers in India, HTMC Group supplies materials that enhance casting precision and reduce rejection rates.

3. Construction and Drilling Applications

Beyond steel and foundry, roasted bentonite is widely used in the construction industry as an additive in cement and concrete for improved durability and bonding. In drilling operations, it functions as a lubricating and stabilizing agent in mud systems, preventing borehole collapse and improving drilling efficiency.

HTMC Group offers customized roasted bentonite grades designed for construction, civil engineering, and drilling industries to ensure superior performance and cost-effectiveness.

Manufacturing Process of Roasted Bentonite

The production of roasted bentonite requires precision and technological expertise. HTMC Group, as one of the leading Roasted Bentonite Manufacturers in India, follows a rigorous process to ensure consistency and quality:

1. Raw Material Selection
   Only high-grade sodium or calcium bentonite with low impurities is selected. HTMC Group sources raw materials from mineral-rich regions like Gujarat and Rajasthan.

2. Drying and Pulverizing
   The raw bentonite is dried to remove moisture and then pulverized to obtain uniform particle sizes.

3. Thermal Roasting
   The bentonite is heated in rotary kilns or furnaces at temperatures ranging between 300°C to 700°C. This roasting process enhances the mineral’s structural stability, removes organic matter, and improves binding characteristics.

4. Cooling and Screening
   The material is cooled and screened into specific mesh sizes according to industrial requirements.

5. Quality Testing
   Each batch undergoes testing for parameters such as pH, moisture content, swelling index, and thermal resistance.

6. Packaging and Dispatch
   The finished roasted bentonite is packed in moisture-resistant HDPE or jumbo bags to ensure long shelf life and easy handling during transport.

This systematic approach enables HTMC Group to deliver roasted bentonite with consistent quality and performance, meeting the expectations of both domestic and international clients.
