4L Micron Powder Mini Benchtop Ball Mill Semi Circle Round Lab 0.75KW

China Tencan 4L Micron Powder Milling Mini Benchtop Ball Mill Semi - Circle Round Shape
 
Overview 
 

 
Vertical semi-circle shape laboratory ball mill is a necessary device used for high-tech materials milling, fine grinding, powder mixing, nano powder making, new product development and small batch production. Tencan planetary ball mill owns advantages and features such as small volume, high efficiency, low noise and complete functions. Tencan planetary ball mill is an ideal equipment for R&D institutions, universities, enterprises’ laboratories to get fine powder samples. Tencan planetary ball mill is designed with four working positions and it makes you get four samples (maximum) at one time. you can also use this machine to get powder samples under the vacuum environment if it is equipped with vacuum ball mill jars for grinding.
 
Working Principle 
 
Vertical semi-circle shape laboratory ball mill has four working positions which can be installed with two or four mill jars on one turntable. When the turntable rotates, the jar axis makes planetary movements at high speed, the balls and materials inside the jars are impacted strongly in high speed movement, and materials are eventually ground into fine powder. Various kinds of different materials can be ground by means of dry or wet grinding method. The smallest granularity of output powder can be reached to 0.1μm or nano scale powder.
 
Applications 
Vertical semi-circle shape laboratory ball mill is widely applied in industries such as geology, mineral, metallurgy, electronics, building materials, ceramics, chemical industry, light industry, medicine, environmental protection and so on. It is especially suitable for production fields like electronic ceramics, structural ceramics, magnetic materials, lithium cobalt acid, lithium manganese, catalyst, phosphor, long afterglow phosphor, rare earth polishing powder and electronic glass. Powder, fuel cell, Zinc Oxide varistor, piezoelectric ceramic, nano material, wafer ceramic capacitor, MLCC, thermistor (PTC, NTC), ZnO varistor, dielectric ceramics, alumina ceramics, zirconia ceramics, phosphor, zinc oxide powder, cobalt oxide powder, Ni-Zn ferrite, Mn-Zn ferrite and etc.
 
Features

Semi-Circle or Square? Comparing the XQM-4A and the XQM-4

Two 4 L models sit side by side in the range: the semi-circle XQM-4A and the square XQM-4. They share the same 4 L turntable, the same 0.75 kW drive and the same 70-670 rpm working speed, so the choice comes down to the housing rather than the capacity. The semi-circle body has a rounded front, which gives it a compact, tidy footprint and a low, stable base, a shape many teaching and research benches prefer. The square body is the more conventional cabinet form. In practice both machines grind to the same fineness; the difference is the look, the bench space and, for some buyers, the familiarity of the housing style.

Estimating Daily Output From a 4 L Benchtop Mill

A common question when sizing a mill is how much powder it can realistically produce. The XQM-4A takes a working load of about 1.32 L across the jars, and with typical mineral or ceramic powders that corresponds to a modest weight per run rather than a large bulk output. Because a run often lasts from a few minutes to a few hours depending on the target fineness, the practical daily figure follows from the number of runs a laboratory can complete, not from the jar volume alone. Where throughput matters, using all four jar positions, keeping a spare set of jars loaded, and not over-grinding are the simple levers; where fineness and repeatability matter more than volume, a smaller number of carefully controlled runs is usually the better trade.

Running a Benchtop Mill in a Shared or Teaching Laboratory

A benchtop mill in a shared laboratory has to be considerate of the people around it. The semi-circle XQM-4A is built with low noise and a low centre of gravity, but it still transfers vibration to the bench, so a sturdy, level surface - and not a glass-topped bench - keeps it steady and quiet. Placing it away from delicate balances and precision instruments avoids any chance of the vibration disturbing a weighing, and leaving clear space at the front makes it easy to load and unload jars safely. In a teaching setting, the safety cover and its interlock, the clear on/off and timer controls, and the habit of one user per machine make the mill easy to run correctly without supervision.

Selecting Grinding Media for Fine and Contamination-Sensitive Work

The jar and the balls are the parts that touch the sample, so they set both the grinding energy and the level of contamination. For very fine grinding of hard materials, zirconia or tungsten carbide media offer high density and wear resistance; for work where metal contact is not acceptable, agate media are a common choice for softer or medium-hard samples. Alumina is often used for ceramics, and stainless steel covers general-purpose work where a small amount of iron is acceptable. A useful rule is to pick media at least as hard as the sample so the wear falls on the sample rather than on the balls, and to keep one jar-and-ball set per material where contamination between samples would matter.

Staged Grinding: From Coarse Feed to Fine Powder

Fine powder is rarely made in a single jump. A staged approach - running the mill for a shorter time to break the feed down, checking the result, then running again, or stepping to smaller media for the final stage - usually gives a more even particle size than one long grind from coarse feed. It also keeps the temperature down, because the material gets short breaks between stages rather than being heated continuously. The XQM-4A's timer and its forward-and-reverse alternating mode suit this way of working, since each stage can be set and repeated. For a new material, a few short trial stages are usually a faster route to the right fineness than guessing a single long run.
