Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

Mill belt drive conversion. The Sieg X1L is a fairly robust little machine and I have used it for many years with few problems. Being a small mill means that it has its limitations and large cuts are not possible in one pass but they can be accomplished with multiple passes.

Motors, Drives Basics of belt drives Power transmission belting has been used for more than 200 years. The first belts were flat and ran on flat pulleys. Later, cotton or hemp rope was used with V-groove pulleys to reduce belt tension. This led to the development of the vulcanized rubber V-belt in 1917.

Due to the costs of lead and ball screws and components, you will find that these type of drive systems will cost more than a belt drive system. Summary If you are looking for high accuracy, a more rugged design, or if you plan to cut harder materials like hard plastics, hard woods and metals, then you will want a system that uses a screw-drive.

Belt drive or gear drive really doesn''t make too much difference if you are running a samll milling machine. Most of the time you will be in open belt drive. The back gears on a B''port type mill are useful for slowing the spindle down when using big drills or fairly large diameter end mills in tough steel.

An inching drive is used as an auxiliary system to the main drive for a large machine such as a ball mill, industrial kiln, conveyor, or elevator. Its purpose is to turn the equipment at a speed slower than the normal operating speed — typically 1 to 2 rpm, although fractional rpms are also common — and to do so at high torque — typically 120 percent of the normal drive torque.

Drive efficiencies: Belt drives suffer from negligible efficiency losses, running at around 98% efficiency (which is what I have shown), while ball screws are >90% efficient. Leadscrews however can be quiet inefficient, especially with smaller leads (due to friction per turn).

There should be no scats at 10 mm unless you are using much too small a grinding ball or the mill charge is much too low. For example, I was told by a client his ball mill feed was P80 = 9mm but when I went to look at the feed belt, I saw this below. The conveyor belt is 15 mm thick, therefore the rocks on it are more like 20-30mm.

Belt drives are made up of synthetic material. This is not stronger as compared to the belt drive. Chain drives are made up of metal which is stronger and more durable. Belt drives are used in mills. The chain drive is used in bicycles, motorcycles, and many more engines. In belt drive, little difficulties have when it gets damaged.

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill’s
