◆ Product Description

The Rolling Ball Mill is specialized powder milling equipment engineered for ultra-fine grinding and mixing, suitable for laboratory use as well as small-scale batch production. Often referred to as a multi-position rolling ball mill, it serves as an excellent choice for scientific research, teaching, experimental work, and small production runs.

Working Principle:

When the machine operates, the grinding media and the materials within the cylinder are rotated to a specific height. Due to gravity, they then fall down along the tube wall. This process crushes the materials through the impact of the grinding media, as well as through friction and shear forces generated by the rolling and sliding media.

Applications: This equipment is widely used in electronic materials, magnetic materials, biological medicine, ceramic glaze, metal powder, nonmetallic minerals, and the development of new materials.

◆ Frequently Asked Questions

1. Q: What is the smallest type available for laboratory use? A: The minimum type is the 0.2L planetary ball mill, measuring 42*30*26cm and weighing 20kgs. We also offer lab types up to 16L.

2. Q: What are the drive modes for the lab ball mills? A: Planetary ball mills are driven by gears and belts, while rolling ball mills are driven by belts.

3. Q: How is the equipment maintained regarding noise and wear? A: We use special wear-resistant gears for laboratory models below 20L to reduce noise. For larger models, oil seals are used. Special gears are easier to maintain and have no risk of leakage.

4. Q: What are your terms of delivery? A: We accept EXW, FOB, CFR, CIF, DAP, and DDP.

5. Q: What is the typical production and delivery time? A: Generally, it takes 5 to 30 days after receiving payment, depending on the items and order quantity.

6. Q: How long is the warranty period? A: The warranty period is 18 months after delivery. We provide free accessories for any quality issues during this time.
