subject: Cement Grinding System And Its Kinds [print this page] Two cement grinding system will be adopted and each system includes a roller press and a 4.212.0m cement mill in closed circuits with O-Sepa high efficiency classifier. The nominal capacity of each cement mill system will be 120t/h of Ordinary Portland Cement at fineness of 320m2/kg. The main motor power of each mill is about 2800kW.
Proportioned mixture are conveyed via belt conveyor and elevator below the proportioning bins to feeding bin, which is equipped with three load cells, above the roller press. The weight signal sent by the cells serves as the feedback signal of materials flow to control the feed volume of belt weighed under the proportioning bins for mixture. Materials from the roller press are sent to V-shaped powder separator. Coarse particles return to the feeding bin above the roller press. Fine product taken by the airflow is sent to cyclone collector and then to the ball cement mill for grinding. Those cannot be caught by cyclone collector are sent to O-SEPA separator of the ball cement mill by airflow.
Materials ground by ball cement mill are transported to N2500 O-SEPA separator by high efficiency bucket elevator. The coarse particles separated return to ball cement mill for regrinding while the fine product is collected by the high efficiency bag filter behind the separator and then conveyed to cement silo via an air slide and bucket elevator.
Vertical cement mill works in the last part of the cement production line, supplying right size cement powder for the industry. Hongxing series vertical mill is widely used for ore and stone crushing production line. We produce vertical mill with high capacity long service time, with a decade of years research of mills, Vertical Roller Mill is designed and manufactured based on our advanced design idea, and in combination with the European technology and the market demand. impact crusher:http://www.hx-crusher.com/impact_crusher.html
Cement ball mill is the most widely used cement mill in cement manufacturing industry. The materials are fed into cement ball milling cavity, which will roll with materials and grinding balls, and then with continues rolling the materials will be resized into cement powder. It is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry process and the wet process. It can be divided into tabular type and flowing type according to different forms of discharging material.
Cement roller mill is a new kind of large scale power mill which is designed specially to solve the problems of low capacity and high consumption of industry cement mills. With a decade of years research of mills, Cement Roller Mill is designed and manufactured based on our advanced design idea and best materials.
