Dry ball mill is the most common ore crushing equipment at present. When it comes to the function of dry ball mill, everyone may think of mineral processing at the first time. If it is said that it can also make sand, it is estimated that many people will not believe it. So today we will analyze whether the dry ball mill can make sand? How many meshes can the finished product be ground?
There are many models of dry ball mills, and each model has different discharge particle sizes. At present, the dry ball mill models with high usage rates on the market are as follows:
900×1800, feeding particle size ≤20mm, discharging particle size 0.075-0.89mm, hourly output 0.65-2t/h;
900×3000, feeding particle size ≤20mm, discharging particle size 0.075-0.89mm, hourly output 1.1-3.5t/h;
1200×2400, feeding particle size ≤25mm, discharging particle size 0.075-0.6mm, hourly output 1.5-4.8t/h;
1200×3000, feeding particle size ≤25mm, discharging particle size 0.074-0.4mm, hourly output 1.6-5t/h;
1200×4500, feed particle size ≤25mm, discharge particle size 0.074-0.4mm, hourly output 1.6-5.8t/h;
It can be seen from the above data that the particle size of the dry ball mill is basically between 0.074-0.45mm, that is to say, the dry grinding of the ball mill can be between 200 meshes and 40 meshes, and the finished product effect is still very good.
Can dry ball mill make sand?
In the past year or two, many small sand making factories have used dry ball mills as sand making machines. The advantages of dry ball mills for machine-made sand are as follows:
1. The effect of the finished product is good: the incoming and outgoing materials of the ball mill can be adjusted, and the discharging particle size is basically between 0.074-0.45mm, which can be used as a sand making machine. The finished product produced by it has a uniform, full and strong cohesion. Through different grades of grinding media, the phenomenon of product over-powder can be reduced and the output can be greatly improved.
2. Good environmental protection effect: The sealing effect of the ball mill barrel is good. In daily operations, there is less dust overflow, and the working noise is small. The noise during operation is ≤70 decibels, which can play a good environmental protection effect.
3. Low operating cost: There are no lubricating parts in the internal structure of the dry ball mill, so the equipment failure rate is very low, the cylinder does not need to be cooled, the equipment has a long service life, stable performance, and can operate continuously for a long time.
Another advantage of using a ball mill for sand making is that the price is much lower than that of a professional sand making machine, but the output is lower, so it is especially suitable for small sand making plants.
