A cement mill is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.
Ceramic sand kiln is one kind of calcining kilns which is a rotary cylinder machine used for calcining all types of materials.
Cement rotary kiln is the main equipment of calcining the cement clinker. The characteristics of a rotary kiln are simple structure, convenient and reliable control of the producing process.
Chute feeder is a kind of feeding equipment which is earlier used in storage trough and it is suitable for the short-distance transport of metallic and non-metallic materials.
Vibratory feeder in the production line can transport the material with the shape of massive and particles smoothly to the feeding device in a stable time.
Themotordrives thegrinding tablethrough decelerator. The materials fall down the center ofgrinding tablefrom feed opening. At the same time, hot air comes into themillfrom the air inlet. Due to the centrifugal force, materials move to the edge of thegrinding table.
