Double Roller Granulator

The double roller granulator is a kind of crushing and granulating equipment widely used in chemical, agricultural, food and pharmaceutical fields. Its design and function make it an ideal choice for a variety of material processing. The double roller granulator is a device that uses two relatively rotating rollers to squeeze the material to form particles. This machine is suitable for granulating various powdered materials, such as organic fertilizer, compound fertilizer, etc.

The double roller granulator has a simple structure, easy operation, and can efficiently convert raw materials into the required particle shape and size. Due to its efficient production capacity and good ball formation rate, it has been widely used in the market.

Composition Structure

Feeding port: The feeding port is located at the top of the equipment and is used to feed the raw materials into the equipment. The size and shape of the feeding port can be adjusted according to different raw materials to ensure that the raw materials can enter the equipment smoothly.

Pressing roller: The pressing roller is the core component of the equipment and is usually composed of two interacting rollers. The surface of the roller is usually engraved with some raised patterns to increase its friction and pressure. When the raw material enters the equipment through the feeding port, the pressing roller will compress it into a certain shape and size.

Template: The template is located under the pressing roller and is used to control the shape and size of the granulation. After passing through the rollers, the raw materials will be squeezed into the holes of the template to form the desired shape and size.

Adjustment device: The adjustment device is used to adjust the distance between the rollers and the template to control the size and shape of the granules. The adjustment device is usually composed of a manual or electric adjustment mechanism and can be adjusted as needed.

Discharge port: The discharge port is located at the bottom of the equipment and is used to discharge the finished granules from the equipment. The size and shape of the discharge port can be adjusted as needed to ensure that the granules can be discharged smoothly.

Working Principle

Extrusion process: The raw materials enter from the feed hopper and are extruded through the mold shell on the two roller skins. In this process, the material is squeezed into dense and hard large blocks, which is called the extrusion process.

Granulation process: The large block material (cake material) after extrusion is crushed and screened to become granular material, which is called the granulation process. The shape and size of the granules are determined by the mold, and the mold can be customized to meet different needs.

Advantages

High efficiency and stability: The double roller granulator has high production efficiency and high yield rate, and can quickly produce uniform granules in large quantities to meet the needs of industrial production.

Easy operation: The equipment has a simple structure, is easy to operate, and is easy to maintain and maintain, which reduces labor intensity and cost.

Strong adaptability: It is suitable for granulation of various materials, such as sludge ceramsite, shale ceramsite, fly ash ceramsite, etc., and can meet different process requirements.

Environmental performance: The sealed cover material receiving form is adopted, the work site is clean and tidy, and the environmental pollution and labor intensity of workers are reduced.

In summary, Lane’s double roller granulator has become an ideal choice for powder or small particle material molding with its efficient production capacity, stable performance, simple operation and economical cost.
