The oil lubrication control system used for heat or cool the temperature of the lubrication. We use oil to cooling and lubricating the machine, and the oil lubrication control system can also recycle oil automatically. But spring cone crusher doesn't have a separated oil lubrication control system, and it uses grease. So you should add grease every eight hrs.  
The hydraulic control system is used to recharge the hydraulic cylinder. Before installation,we will fix a certain current value by electric control cabinet, and if the crushing cavity is filled with too much material or there's iron or steel come into cavity, the current value of the crushing cavity will larger than that we fixed. And in this way, the oil in the hydraulic cylinder will be extruded to the accumulator, and therefore, the Bowl will be lifted and the material will be discharged out. That is why we say it is fully automatic, you don't need to handle it by hand, but it is not controlled by computor, completely because it is operated by the hydraulic system.
The electric control cabinet, which is one of the most important three control systems, can control all the other two systems by electric control cabinet. The electric control cabinet is not PLC system, it is very easy to operate and with no complicacy. That is to say, it is not controlled by computer, if you need to control by computer, it is also OK. But I think it will be more complex. However, in spring cone crusher, you can only control the bowl by electric control cabinet.
