Before purchasing a mill, we need to determine which mill equipment we need to purchase according to the materials we need to process. At present, in the market, crushing equipment can be divided into 6 categories, in addition to the more common cone mill and roller mill in industrial production, in ore field is rare grinding machinery and compound pendulum jaw mill, conical mill, return mill and vertical shaft impact mill, etc.. Among them, the conical mill is commonly used as the secondary and tertiary crushing equipment in the sand and stone field, so the diameter size of the cone bottom circle is often used as the division standard of the specification in modern industrial production.

In the purchase of mill equipment should pay attention to the following principles:

1. When choosing conical milling machine, attention should be paid to checking whether the hook, boom, wire rope, control and transmission mechanism, hydraulic system and other parts are normal.

2. Before purchase, the equipment can be used for trial operation to observe whether the equipment operates smoothly and whether the discharge of materials is normal. Also need to pay attention to the various oil temperature and pressure readings are normal.

3. Check whether the connecting parts of the internal parts of the equipment are loose. If it is a second-hand equipment, it is necessary to check whether the internal lining plate is worn or not. Because the worn lining will make the grain size of the discharge coarse, and seriously damage the internal parts of the mill equipment.

4. Finally, don't forget to check the oil temperature, tubing pressure and other factors in the cooler.

In short, mill equipment is a kind of more commonly used industrial equipment, so it is extremely necessary to be careful in the purchase, because once the machine failure is bound to affect the daily production, serious industrial accidents.
