What is the working principle of calcium carbonate double roller granulator?

Double Roller Granulator for Calcium Carbonate is a device for converting powdered calcium carbonate into granular products. It is widely used in chemical, construction, pharmaceutical and other industries with high efficiency, energy saving and environmental protection. This article describes in detail the working principle of this equipment and its advantages.

Equipment composition

Dual roll granulator for calcium carbonate consists of the following main parts:

• 1. Feeding system: feeds the material evenly between the rollers.
• 2. Roller system: two rotating rollers are the main elements of pelletizing, usually made of alloys with high hardness and wear resistance.
• 3. Compression system: provides the pressure required for granulation.
• 4. Discharge system: transports the formed pellets to the next stage of the process.
• 5. Control system: regulates the operating parameters of the equipment, such as roll speed and pressure.

Working principle

Feeding Stage

Powdered calcium carbonate is fed through the feeding system into the granulator, the gap between the rolls can be adjusted to control the granule size.

Compression and formation

• The powder is compressed as it enters between the rollers. Due to the rotary motion of the rollers, the material is continuously compressed, gaining higher density and mechanical strength.
• Under the pressure of the rollers, the powder material is gradually molded into granules. The surface of the rolls is usually provided with grooves or patterns to help shape the material.

Pellet Forming and Adjustment

• The size and shape of the formed pellets can be adjusted by changing the roller spacing and the speed of the rollers.
• During the compression process, binders can be added or temperature can be adjusted to improve pellet quality and strength.

Discharging and cooling

After granulation, the formed granules are discharged through the discharge system. Further cooling, screening and packaging is carried out as required.

Advantages

• – High efficiency and energy saving: the twin roll pelletizer provides high output with low energy consumption.
• – Environmentally friendly: the pelletizing process is virtually dust free, thus meeting environmental requirements.
• – Flexible: simple adjustment allows you to change the size and density of the pellets, adapting to different production needs.
• – Ease of use: the equipment is easy to operate and maintain, reducing labor costs.

Areas of application

Calcium carbonate roller granulator is widely used in building materials, feed, rubber, chemical, pharmaceutical, food and other industries. Especially in the occasions where calcium carbonate powder materials need to be processed and converted into granular products, this equipment has significant advantages. For example, in the building materials industry, calcium carbonate powder can be made into granular form, which is used to improve the fluidity and usability of the products; in the feed industry, calcium carbonate powder can be made into granular feed additives, which improves the utilization rate of feed and the digestive absorption rate of animals.

Structural characteristics

• Integrated welding and processing frame: it ensures the machining, matching precision and form tolerance of each part, and effectively improves the installation precision and reliability of the whole machine.
• Belt transmission system: belt transmission is adopted between motor and reducer, which is smooth and reliable, and has overload protection function for motor.
• Movable roller adjusting device: The movable roller device can adjust the pre-pressure of the movable roller device by adjusting the position of the bearing seat, so as to get the products that meet the requirements.
• Split structure of roller and hub: it is easy to replace the roller and reduce the maintenance cost.

Calcium carbonate roller granulator can produce what material

Calcium carbonate roll pelletizer can transform calcium carbonate powder and many kinds of inorganic raw materials into granular materials through physical extrusion process, and its core applications include: production of modified calcium carbonate particles, processing of talc/kaolin and other non-metallic mineral particles, the preparation of magnesium oxide/calcium phosphate and other chemical raw material particles, through the adjustment of the roll parameters can be adapted to the needs of the particle size of 0.3-10mm, covering the building materials, chemical industry, environmental protection, new energy and other fields of granular production scenarios. It covers the granular production scenarios in the fields of building materials, chemical industry, environmental protection, new energy and so on.

Understanding the operation of the Dual Roll Calcium Carbonate Granulator allows you to optimize your production process, improve product quality, and meet a variety of market needs. With the development of technology, the performance of this equipment in automation and intellectualization continues to improve, providing more powerful support for modern industry.
