Bead mill, also known as sand mill or pearl mill, is a type of ultrafine wet grinding machine. It is an efficient and high-energy wet grinding machine with multiple cooling systems, automatic stop control system, and continuous production system. Widely used in various industries such as paints, coatings, colorants, inks, papermaking, adhesives, chemicals, new materials, etc. By grinding the medium (grinding beads) rotating at high speed inside the grinding chamber, materials are crushed or dispersed to achieve micrometer to nanometer and decimeter levels.
There are different types of bead mills to meet the production needs of different industries. POLYC provides different types of high-quality and high-efficiency professional bead mills for the production of various chemical industries.
Working Principle
The horizontal bead mill is a wet grinding machine used for continuous production of solid-liquid material. The motor is driven at high speed to drive the central axis in the grinding chamber and other forms of grinding device such as grinding pins or grinding discs on the axis to rotate at high speed. The grinding zirconium beads in the grinding chamber start to run rapidly and collide with each other due to the rotational power and centrifugal force. The strong shear force, impact force, and impact force break the material particles into smaller sizes and achieve a certain fineness requirement. After the grinding is completed, the zirconium beads are still in the grinding chamber due to the fine gap technical of the sieve, while the material is discharged through the sieve.
Main characteristics
Different materials of grinding pins/discs
Based on the customer's production process and material characteristics, we will customize the bead mill specifically, such as capacity, size, important grinding material selection, type of grinding medium, process temperature, wear rate, etc.
POLYC Bead Mill Feedback From Customers
The color strength and transparency of the ink or pigment by our bead mills are significantly better than those of bead mills on the market.
Notice of Using Bead Mill
The pumping speed of the air pump should not be too fast. If the pump speed is too fast, the pressure inside the chamber will be too high（Please check in a time whether the pressure on the pressure gauge exceeds the limit pressure of 0.4 or not）which will push the beads towards the screen sieve and make it easier to block, especially if the material viscosity is high. After grinding the material, the bead mill isn’t used for a few time, need clean the material remained in the pipe of the air pump in time.
When the current and voltage are unstable, it will cause damage to the motor and abnormal shutdown.
When the machine is used for a long time and the vulnerable operation buttons on the control panel are damaged, it is necessary to replace a new one in time. Otherwise, when the customer starts the machine to grind materials, liquid will inevitably enter, which will cause the machine to leak electricity and shut down.
