Choice of Grinding Jars & Grinding Balls

    In order to prevent excessive abrasion, the hardness of the grinding jars used and of the grinding balls must be higher than that of the material used. Normally, grinding jars and grinding balls of the same material should be chosen. However, the size of grinding jars and grinding balls should be determined experimentally if necessary.

    Stainless steel balls, zirconia balls, alumina balls, PU balls, steel carbon balls, tungsten balls, agate balls, hard metal balls, silicon nitride balls, high wear resistant steel ball, manganese steel balls, cemented carbide, crystal glass and other special metal materials.

Working Principle
    The planetary gear ball mill is named after its working mode similar to the trajectory of planetary motion in the solar system, that is, the planets revolve around the stars and rotate at the same time. On the working turntable, four or two symmetrical ball mills are installed at the eccentric position of the middle fixed gear. When the turntable rotates (revolution), it drives the ball mill to rotate around the axis of rotation, and the direction is opposite to the rotation of the turntable, forming a planetary motion. The transmission ratio of revolution and rotation is 1:2 (one revolution of revolution is two rotations of rotation). When the balls in the ball mill move together with the ball mill, they are affected by the superposition of Coriolis force (i.e. rotational deflection force), generating strong impact and friction. This combination of impact and friction allows the grinding media balls in the ball mill jar to grind and mix the samples at high speed.

    Ball mill jars are impacted strongly in high speed movement, and samples are eventually ground into powder. Various kinds of different materials can be ground by the mill with dry or wet method. Minimum granularity of ground powder can be as small as 0.1μm.

FAQ

​1.Q: I need a mill machine for lab use, what's your mini type?
A: The minimum type is 0.2L planetary ball mill, Model XQM-0.4A in size of 42*30*26cm, machine weight 20kgs. We have other types from 0.4L to 16L for lab application, and 20L-100L for production type.

2.Q: what's the drive mode of your lab ball mill?
A:Planetary ball mill is drived by gear and belt.
Rolling ball mill is drived by belt.

3.Q: How do you maintaince the equipment?
A:We have been using oil seals for a long time, even earlier than the main planetary ball mill factories in China. but we have made more detailed classifications according to different specifications and models: XQM-20 and above use oil seals, while XQM-20 and below use special wear-resistant gears for laboratories. Because we know very well that oil seals themselves are not the purpose, but the purpose is to reduce gear noise. Special wear-resistant gears have very low noise, and the effect is no different from that of oil seals, and special wear-resistant gears are superior to oil seals in terms of transportation, maintenance, and maintenance.

The oil seal has the risk of leakage during transportation and equipment using.

4.Q: What is your terms of delivery?
A: EXW,FOB, CFR, CIF,DAP,DDP.

5.Q: Can you accept small quantity sample order before production?
A: Yes, we can offer sample for your testing first before production, but the customers have to pay the courier cost.

6.Q: What is your production time?
A: Generally, it will take 5 to 30 days after receiving your advance payment. The specific delivery time depends on the items and the quantity of your order.

7.Q: What is your terms of payment?
A: T/T 30% as deposit, 70% balance against the copy of original B/L. Or 100% L/C at sight. We'll show you the photos of the products and the copy of original B/L before you pay the balance.

8.Q: How long is the warranty period?
A: 18 month after delivered. During the warranty period, if there is any quality for machine, free accessories will be provided.
