The high pressure briquetting machine or the high pressure ball press machine is used to press many kinds of materials such as gypsum, coal powder, mineral powder, scale cinder, slag, fine iron powder and aluminum ash etc.
Lime briquetting machine is also known as lime briquette machine, lime pressure ballmachine, or lime ball press machine.
Rotary kiln is also known as lime rotary kiln. According to different processed materials, rotary kiln can be divided into cement kiln, metallurgy chemical kiln and lime kiln.
Because of its high humidity and strong stickiness, the coal slime can’t be dried by the traditional drying equipment.
High-strength micro powder mill is a widely used device that is based on the Raymond grinder, by increasing the roller compression in the working cavity, analyzing machine air conditioning improvements.
Lime kiln is a kind of environmentally friendly, energy-saving and high degree of mechanization and automatic equipment.
