The Hydraulic System of a Hydraulic Three Roll Mill

Hydraulic Three Roll Mill

Three roll mills are widely used in the production of paints, inks, cosmetics, and other products that require the precise blending and dispersion of materials. Hydraulic systems have revolutionized various industries, and one particular application where they shine is in hydraulic three roll mills. 

Details of Three Roll Mill

  • Two types: handwheel and digital control gap
  • Safe scraper socket, Emergency-stop
  • Space-saving desktop models
  • Drip tray for easy cleaning

Application: Paint, Adhesive, Battery, Pharmaceutical industry, Cosmetic

This type of three roll mill consists of three horizontally positioned rolls that rotate in opposite directions, with precisely controlled gaps between each roll. The material being processed is fed between the rolls, and as the rolls rotate, the material is subjected to intense mechanical and hydraulic forces. These forces facilitate the blending, grinding, and dispersion of the material, resulting in a homogenous and smooth product.

A hydraulic system consists of various components that work together to generate, control, and transmit hydraulic energy. In the case of a hydraulic three roll mill, the hydraulic system primarily consists of a hydraulic power unit, hydraulic cylinders, and hydraulic control valves.

The heart of the hydraulic system is the hydraulic power unit. This unit is responsible for generating hydraulic energy by converting mechanical energy into hydraulic pressure. It typically consists of an electric motor, a hydraulic pump, a reservoir, and various valves and filters. The electric motor drives the hydraulic pump, which draws oil from the reservoir and pressurizes it. The pressurized oil is then directed to the hydraulic cylinders, which play a crucial role in the operation of the mill.

The hydraulic cylinders of a hydraulic three roll mill are responsible for applying the necessary force to the rolls. These cylinders are usually positioned on either side of the mill, parallel to the rolls. Each cylinder is equipped with a piston that moves back and forth under hydraulic pressure, exerting force on the rolls. The force applied by the cylinders determines the gap between the rolls, which is crucial for achieving the desired material processing results. Precise control over the hydraulic cylinders allows for accurate adjustment of the roll gap, ensuring consistent and uniform processing of the material.

Hydraulic control valves are the key elements that regulate the flow and pressure of hydraulic fluid within the system. These valves serve multiple purposes in a hydraulic three roll mill. Firstly, they control the flow of oil to the hydraulic cylinders, enabling precise and responsive adjustment of the roll gap. Secondly, they provide safety features by controlling the pressure within the system. High-pressure relief valves are employed to prevent overloading and potential damage to the mill. Additionally, various directional and flow control valves enable the operator to manipulate the movement of the hydraulic cylinders, ensuring smooth and controlled operation of the mill.

The hydraulic system in a hydraulic three roll mill is designed with several advantages in mind. Firstly, the hydraulic system offers precise control over the roll gap, ensuring consistent product quality. This precision is vital, especially in applications where uniform dispersion is crucial, such as in the production of inks and pigments. Secondly, the hydraulic system provides ample power to the mill, allowing it to handle high viscosity materials with ease. Whether it is thick paints or adhesive formulations, a hydraulic three roll mill can process them efficiently. Furthermore, hydraulic systems are known for their durability, reliability, and longevity, making them ideal for industrial applications.

Three Roll Mill For Grease

The three roll mill plays a vital role in the grinding of grease. Grease is essentially a kind of lubricating oil, which is a solid or semi-solid product formed by one or more thickeners through the grinding and dispersing action of a three roll mill.

Three Roll Mill For Attapulgite

Three roll mill is the main equipment for grinding attapulgite. The attapulgite is ground and dispersed mainly because it is a natural colloid. Even if the size of the attapulgite reaches 0.1mm, it cannot be easily dispersed by the machine, so the final state of attapulgite formation has been greatly developed.
