In the hydrated lime production process line, it is necessary to equip the grinding equipment at the output end of the quick lime digestion system, so as to grind the semi-finished hydrated lime into finished hydrated lime with target particle size. Then, Does the hydrated lime could be ground by Raymond Mill?
In order to expand the scope of application of grinding objects, most of the calcium hydroxide Raymond mills on the market are equipped with more than three grinding rollers, such as 4R Raymond mills or 6R Raymond mill. However, since the slaked lime itself has the characteristics of low hardness and friability, if the existingcalcium hydroxide Raymond mill with multiple grinding rollers are directly used, the excessive number of grinding rollers will lead to problems such as large load of the drive motor, high energy consumption and low grinding efficiency. In addition, since impurities (such as calcium carbonate and insufficiently digested calcium oxide) are inevitably mixed into the grinding chamber in the semi-finished hydrated lime fed, which will not only affect the purity of the final finished hydrated lime, but also because these impurities have the characteristics of high density and hardness (relative to the hydrated lime), they will be difficult to be ground to the target particle size and discharged by wind separation, In this way, impurities will deposit in the grinding chamber after long-term grinding, which will affect the feed rate and final production capacity. In addition, the existing calcium hydroxide Raymond mill also has the problems of poor inter equipment linkage and failure to maintain automatic warning, which affects the further improvement of production capacity and the timeliness of equipment maintenance.
The fineness of the finished product can be adjusted from 80 mesh to 400 mesh. At the same time, it can solve the problem that the traditional lime lime machine cannot produce in a large scale. It is a new type of flour mill product with high efficiency and energy saving, and is a kind of equipment with high cost performance among many flour mills. Its production advantages are as follows:
1. High yield: high output, single unit output up to 30 t/h
2. Low energy consumption: low installed capacity of single machine, low energy consumption per ton
3. The fineness is easy to adjust: the fineness is adjustable at 80-600 meshes, and the particle size distribution is uniform
4. Strong slag discharge function: precise slag discharge according to customer requirements
5. Small footprint: small footprint of single machine
6. Stable operation: low vibration, low noise, stable operation and reliable performance
7. Environmental protection: the whole machine system is sealed to basically achieve a dust-free workshop
