With around 25 years rich experienced engineers in this area, ELE strictly control the every single process from raw material to processing, to assembling to final products testing. Strictly control the accuracy during processing, 

For equipment, superior performance sometimes does not mean good quality. Quality can be understood as mechanical stability which means it will not be damaged or malfunction frequently. Therefore, the definition of an excellent equipment should has excellent mechanical stability on the basis of superior performance.However,how to ensure the quality of the equipment? We think It needs to start from two aspects:

1. High requirements for accuracy;

2. Strict quality control management system

First of all, accuracy is extremely important to the equipment. For example, if the accuracy of the sand mill is not good, the main shaft will happen runout greatly, which will damage the mechanical seal in a short time and seriously affect the service life of the mechanical seal. 

However, accuracy is actually a display of the comprehensive technical level and manufacturing capabilities of the machinery manufacturer due to it involves many aspects of manufacturing. For example, excellent design(structure), complete and high-quality process equipment (machine tools), reasonable and excellent processing technology, skilled technical workers, strict inspection system,and so on. The figure below is a simple diagram.

For quality control, ELE has strict requirements at every step. We have a professional inspection department which is responsible for each step of the inspection, and we also have a strict inspection system which involves in inspection of raw materials, single processed parts, assembly parts, dynamic and static inspection of machine.,and so on.

In summary, Excellent design&accuracy&quality control management system are a solid guarantee for the quality of ELE equipment.

Bead mill machine mainly consists of feeding pump, grinding chamber, grinding beads, motor, machine body, cooling system, protection system,control system ...etc.

Let's take ESW-1.0 bead mill as an example. Details are showed as follows:

Which Other Technologies Can Replace Bead Mill Machine?

Basket mill can be a replacable mill machine of bead mill. It can achieve utlra-fine grinding effect too. Comparatively speaking,  the two types machine have its own advantages. 

For bead mill, motor power is larger,  beads filling ratio is higher, grinding time is shorter and target particle size distribution is narrower. And it can be used to continuous production in that the bead mill is highly automated. Not only because protective devices can be installed on the bead mill and it can automatically shutdown if machine pressure beyond set value, so that one person can operate multiple machines,  but also because the machine cleaning and grinding process are the same , thus don't require workman to do cleaning else. But the price is higher.

For basket mill, it can do grinding and dispersing together, convenient to operate and easy to clean so it particularlly suitable for paint and ink production with many colors. But it requires workman to transfer materials and clean inner  basket  chamber after grinding every time. And also it can't be used in continous production. But price is lower.

How Does Bead Mill Machine Work?

Motor of bead mill machine drive in high speed, bring the rotors (Pin/Turbo/Disc) in high speed rotation, the beads between the rotors are moved fast and collide each other, bring shearing force, impact force and hitting force to the particles, break the particle to be smaller size. With the help large area centrifugal separator sieve, the grinding media keep stay inside the grinding chamber, the particles go through the sieve gap (usually 0.1mm, 0.3mm, 0.5mm, we also can make 0.05mm) for discharge. 

A horizontal bead mill is wet grinding machine for continuous production. The working way is:

Working Principle

Feeding pump: like diaphragm pump or gear pump, to transferring the material into the grinding chamber which is filled with grinding media (normally it is Zirconia Beads, glass beads or steel beads. We recommend you 95% zirconia content Zirconia beads).

Grinding: These beads move along with high-speed Grinding disc. The grinding beads hit against the material which needs to be grinded with high power.

Discharge: After thousands of times hitting, the material will get smaller particle size, and then it will be separated with the beads by a special sieve which installed in the middle of the grinding chamber cover.

Compared to three-roller mill, bead mill doesn’t need high working skill, easy to operate, and bead mill can work continuously on production line, by this way, using bead mill, you will get high quality product, and lower cost.

On the market, there are several types bead mill such as: disc type bead mill, pin type bead mill, turbo type bead mill, and each type have different size, to satisfy different customer’s need: different product, different viscosity, different working capacity….

In all, bead mill is now widely used in Industry such as: paint, ink, medicine, food, cosmetics, pesticide… 

How Many Types of Bead Mill Machine Are There?

In terms of machine rotor structure, we have three types: disc type, rod pin and turbine. In terms of rotor and cavity materials, we have alloy steel, ceramics, and polyurethane.

How Do You Troubleshoot Bead Mill Machine?

Generally, our equipment will be shut down when a failure occurs. Do not rush to restart the machine at this time. Turn on the electric control cabinet first and the fault indicator will light up. Through the fault light, we will find out the corresponding fault location and cause.

Fault indicator

Fault indicator

Faults and Troubleshooting Method:

A)Feeding pump can not transfer materials or showing pressure>2kg on the pressure meter 

I.  Check feeding pump

II. Check whether chamber discharging end blocking, open the outlet port nozzle, clean the discharging sieve.

B) Main motor doesn’t work

III. Check power supply

IV. Security instrument is in protection state, floating ball of liquid level falls to the bottom of the central pole or pressure in mechanical seal cooling tank is too low, ﹤0.25Mpa.

V. Check thermal relay

VI. Check whether cooling liquid transfer pump is working normal

C) Rotor don’t rotate ( while main motor is working)

VII. V-belt is too tight

VIII. Rotor is stuck by media or materials

After troubleshooting, press the emergency stop button. Restart the machine

What Are the Factors That Affect the Service Life of the Bead Mill Machine?

Failure to operate the machine in accordance with our training guidelines.

1. The feed particles are too large or the viscosity is too high to cause the machine block, and the machine is forcibly restarted when the fault is not eliminated. It is very likely that the mechanical seal will be damaged after several times, resulting in liquid leakage.

2. When the current and voltage are unstable, it will cause damage to the motor and abnormal shutdown.

3. The cleaning of the material is not complete, and the material remains in the cavity, which causes the filter screen to be blocked.

4. The mismatch of the selected zirconia beads and the filter screen, and the feeding speed is too fast, will cause the machine to block and cause the shutdown phenomenon.

The above behaviors will affect the service life of the machine.

Which Factors Control Particle Sizes in Bead Mill Machine?

There are many factors that may influenced the final particle size, such as：

1. Grinding type, there are three types bead mills in term of grinding types, Disc type, Pin Type, Turbo type, each type due the grinding efficiency and energy consuming different, the final particle sizes will be different too.

2. Zirconia beads size,  when bead mill working , shaft bring engergy to zirconia beads which cause crushing power on the particle size, the gap space among beads and beads influence the smallest particle size it can reach.

3.Beads loading ratio, in a reasonable scale, the higher beads loading ratio, the higher grinding efficiency, more beads means more crushing power and possibility that hits the particle size.

4.Speed, the higher rotating speed brings higher power and energy, in reasonable scale, the speed is higher means efficiency is higher too.

5.Feeding speed, feeding speed lower means that material has longer grinding time in the grinding chamber, this influence the final particle size too.

6.Temperature, pressure, etc, according to different material characteristics, sometimes temperature and pressure will influence the final particle size too.

What Are Bead Mill Machine Specifications?

When we say the specifications of a bead mill, we generally starts from the following aspects:

1.the grinding type, such disc type, pin type and turbo type.

2.the grinding part material, metallic and ceramic.

3.the motor power.

4.the grinding chamber volume

5.the sieve size

6.the zirconia beads size

7.the other assisting devices

Which Factors Determine Quality Bead Mill Machine Output?

1. the machine handling capacity, flowrate. Bigger motor power always has bigger grinding chamber, meanwhile bigger flowrate.

2. the final particle size requirements, according to different particle size requirements, the grinding time, speed and rounds could be different.

3.the feeding speed, the higher feeding speed lead a higher outputing speed.

What Are the Properties of Materials You Can Process Using Bead Mill Machine?

Horizontal sand mill is a wet fine grinding equipment. Its main function is to break the phenomenon of secondary agglomeration of particles. At the same time, it has a certain crushing ability according to different physical properties. Therefore, the products produced by sand mill must have at least the following two characteristics:

1. The working manner of sand mill is wet grinding, so the material is required to have fluidity and be in the state of slurry, liquid, solid-liquid mixture, etc. The products produced by the sand mill are finally in the state of fluid slurry, suspension agent, etc., not powder state.

2. Sand mill is aimed at fine grinding, so it has requirement for the feeding particle size (preferably less than 100 microns). The material needs to be fully pre-dispersed before entering the sand mill.

How Do You Charge and Discharge Material from Bead Mill Machine?

The horizontal sand mill has two discharging methods, one is the outdated dynamic and static ring discharging mode（gap separator), and the other is the current popular large-flow centrifugal tubular separator discharging mode. The comparison of the two methods is shown in the figure below:

Comparison Between Dry and Wet Bead Mills?

Talking about grinding bead mill, there are dry grinding and wet grinding two methods, As for the nano material powder manufacturer, of course, they wish to use dry grinding to get nano particle, but for dry grinding, the temperature of powder will be increased quickly by the high energy impacted, besides when the powder become nano particle how to prevent the explosion proof, it is hard to solve. SO here comes the wet grinding, It is the cost-effective, Avoid the high cost and solve the problem of dry grinding hard to reach nano particle, usually for dry grinding, it only can reach 8microns, if you want finer, then better to choose wet grinder. 

For dry grinder methods, usually we could use below machines: 

1) Jet Mill 

2) Ball Mill 

3) High pressure Agitator mill; 

For Wet grinder methods usually we could use below machines: 

1) Pin type bead mill 

2) Turbo type bead mill 

3) Disc type bead mill 

The difference is as below: 

1)     Dry grinder: Advantages: short production time, low cost, Disadvantages: Power is easy to get aggregation, Hard to reach nanometer particle size, Easy to increase temperature when grinding 

2)     Wet grinding mill: Advantages: Could reach nanometer particle size, high efficiency;  Disadvantages: Long production time, after treatment is very complicated and high cost
