The new system acts as a setting adjustment system and releases the crusher cavity to open in the event of hitting non-crushable, over-sized material. In cases where non-crushable material like a piece of iron enters the crusher cavity and generates a high pressure, the relief valve is opened and releases the hydraulic oil from the cylinders. The active control system is based on three hydraulic cylinders and an ultrasonic sensor attached to the rear of the crusher. The new protective system adds greatly to crusher availability, especially in recycling applications.A new, advanced active setting control for the plant is now available.
It is a kind of non-ferrous metal that is closely related with human being. Copper has wide application in electrical, light industry, machinery, construction, national defense industry and so on. After a series of process, copper ore can turn into copper concentrate with higher copper content. After smelting and refining, copper concentrate can become refined copper. As we know, the natural copper exists in the copper ore.Copper is one of the earliest found and use metals.
They can grind materials based on the end-use of materials.These devices can also be used for grinding and processing of gold, copper, silver, manganese, marble, granite. These energy efficient equipment is very popular.Portugal marble powder plants include: marble ball mill, marble Raymond mill,medium-speed T-mill, marble super thin grinding, marble vertical mill and so on.
Lubrication is not uniform and blocked mobile crushing machine bearing lubrication oil too much or too little, will make the bearing lubrication is not good, friction phenomenon will increase, causing the heating of the bearing, elevated temperature; and if not cleaned regularly bearing oil hole and an oil groove and lubrication oil hole will be dust and other foreign matter blocking, added the lubricating oil can’t be into the need to lubricate the parts, resulting in bearing temperature rise.
