What is basket mill?

YourTech EBM-Series basket mill is a wet grinding machine that combines grinding and dispersing together, widely used in inks, paints,coatings, color paste production and other related industries. It can achieve ultra-fine grinding effect. It has unique self-absorbing impeller design, smoothly feeding , with anti-reflux device, no beads leaking, smaller sieve design, which can used smaller grinding beads, get finer particle size and narrow particle size distribution.

Working Principle:

When motor drives the shaft at a high speed , the upper part of basket chamber appears votex and a strong suction force was generated by self-absorbing impeller, thus materials is inhaled into inner chamber. The beads driven by pins inside the chamber produces force in all directions and sunder material through constant collision and friction. After materials out from sieve generator, it will be dispersed by high speed disc and returns to basket chamber repeating grinding cycle. That is why smaller particle size and narrower particle distribution can be achieved finally.

Which other Technologies can Replace Basket Mill Machine?

Basket mill is a good grinding mill for batch materials, But basket mill have its limitation， when you have single color material large capacity need continuous process operation, Horizontal bead mill is best machine replace basket mill.

How does Basket Mill Machine work?

The working principle of the basket grinder is the high-speed suction of the self-priming impeller → the extremely fine grinding in the grinding basket → the high-speed rotation of the dispersing disc to produce dispersion, mixing, and circulation effects → thus forming a high-efficiency cycle of suction, grinding and discharging.

Feeding: impeller rotate in high speed, create powerful suction and vortex, push the material into the grinding basket

Grinding: grinding pins on the shaft rotate in high speed, push the zirconia beads inside the grinding basket in fast movement, collide the material, hit the material, impact the material, create impact force, friction force, shearing force to the material, break the aggregation, reach finer particle size.

Disperser: Disperser disc rotate in high speed, create centrifugal force, force the material from the grinding basket out, getting dispersion force.

The problem of material turning is avoided, the dead angle of circulation is avoided, and excellent grinding effect can be obtained in a short time. Suitable for small batch production (easy to change color), pre-dispersion and grinding can be completed in a paint slurry tank. The speed of the main shaft can be adjusted, the operation is stable, the noise is low, the auxiliary equipment is less, the cleaning is convenient, and the grinding medium is easy to change.

How many Types of Basket Mill Machine are there?

How do you Troubleshoot Basket Mill Machine?

When customer are using the machine, if the motor doesn’t work, firstly check whether the power supply plug is connected, whether the connector is loose; whether the converter operation is normal or not. If after the breakdown mentioned above are eliminated, it still cannot work normally. Ask professionals to maintain it or contact with our after-sales service department. Don’t ask the person who is not familiar with the machine to dismount the machine in case of an accident.

Which Factors Determine Quality Basket Mill Machine output?

Talking About the Basket Mill machine output, we have to say the final particle size, The main function of basket is to reduce the particle size to the required size like 5microns, 2microns, 1 micron or even nanometers. The factors to determine the final particle size is below:

1) Bead size: usually, smaller beads size, smaller final particle size, so the basket mill could use smaller size beads is very important, our YourTech basket mill adopt new constructure, with special screen which could be smaller gap size, so that we could use smaller bead size.

2)Bead filling ratio: More beads filling ratio could create more shearing force, more impact force and more hitting force and more friction force, could get finer particle size, our ELE basket mill could reach bead filling ratio to be 80%.

3)Kinetic energy: decided by motor power

4)No leaking beads, no beads stuck, our YourTech basket mill adopt a special anti-reflux device, no beads leaking, no beads stuck, guarantee the stable production.

5)Temperature: for finer particle size, usually higher temperature will create the aggregation, our YourTech basket mill provide multiple cooling system, a) grinding basket with jacket b) tank with jacket for cooling.

What Influences the Capacity of Basket Mill Machine?

Above questions talking about the five factors determine the output and final particle size of basket mill, like beads size, filling ratio, kinetic energy, temperature and anti-reflux device. All above factors effected by the accuracy and the structure, The new structure make the beads grinding at active area, prevent the useless working by old structure, increase the performance. The accuracy between the three support rods for the grinding basket, the accuracy between the shaft and bearing and the shaft sleeve. Guarantee stable working and continuous production.

Can Basket Mill Machine Produce Intermediate Grades of Particles?

Yes, from micron level 1-50 microns, to nanometer level 500-800nm.

Basket mill is suitable for grinding paints, coating, ink, and related chemical material, the grinding beads can use from 0.2mm-2.4mm, it is suitable for different particle size requirements.

Which Material is used to make Basket Mill Machine Contact Parts?

1) Harden Alloy Steel

2) Ceramic type

The basket mill contact parts generally uses SS304 or SS316L stainless steel, also some acid material can choose to use anti acid material such ceramic and PP, the grinding parts uses hard alloy steel or ceramic.

Cearmic generally refers to ziconia oxide grinding peg or dics, silicone carbide inner chamber, it’s used for anti metal or color contamination.

What are the Properties of Materials you can Process using Basket Mill machine?

According to many years of experimental experience of YourTech Company. the new structure basket mill has the advantages of short grinding time and narrow particle size distribution when the viscosity value is lower than 8000cps and the target particle size of the material is 0.8-15 microns. At the same time, the cooling system of basket jacket and material cylinder block can solve the influence of high temperature on grinding effect to a greater extent. Especially for the grinding of some heat sensitive materials, the minimum controllable range is 23 ~ 30 ℃. This is the technical difficulty that most competitors can’t match.

How do you Charge and Discharge Material from Basket Mill machine?

Raise the basket before preparing the material for grinding, pour the proportioned liquid into the tank first, and then slowly pour the powder material against the edge of the barrel wall. And the mixture should not be too full. It is generally recommended to add about 80% of the cylinder volume.

After all the main materials are added to the cylinder, slowly put down the basket body until the liquid level completely over the dispersion plate and reach the height of the basket body about 8~10cm.

Start the machine at low speed and rotate at low speed for 1 minute, then slowly let the basket body completely penetrate the material to increase the speed. After the grinding is completed, the customer can choose the method of gravity discharge or conveying pump discharge. We have designed a discharge hole on the lower side of each cylinder to install a discharge valve.

At the same time, the cylinder bottom inclination angle design greatly reduces material residue and is easy to clean.
