2 sets of MTW175 European type grinding mill were put into operation in South African limestone powder production site
Recently, Kefid's large limestone powder production line in South Africa has been officially put into operation. The production line is configured with 2 sets of MTW175 European type grinding mill.The capacity is up to 30 tons per hour which exceeds customer's expectations.
The main component of limestone is calcium carbonate (CaCO3). Its Mohs hardness is 3, which belongs to the easy type of ore for grinding. Meanwhile, in view of the customer's raw material size is too large, we configure the complete production line: jaw crusher + bucket elevator + vibrating feeder + 2 sets of MTW175 European type grinding mill.
Chunks of limestone were fed into jaw crusher for primary crushing, the output size can reach 25mm.Then the material will be sent to storage hopper by elevator, and then continuously fed into grinding mill by vibrating feeder for grinding. After grinding the material was classified by powder concentrator. Under the action of the impeller of powder concentrator, the material does not meet the required fineness are falling into the grinding room for re-milling. In line with the requirements of the fineness of 200 mesh material with the airflow via conduit into the cyclone powder collector for collecting, by discharging,it shall be finished powder. The entire system is a closed loop system and run under positive and negative pressure state.
MTW series European type grinding mill is new grinding equipment which absorb the latest technology and ideas in Europe with overall drive bevel gear, internal lubrication system, arc air channel and other independent patent property rights.It is fourth-generation upgrade raymond mill. In addition, the advanced dust removal system makes dust removal efficiency up to 99.9%. Whether environmentally friendly or production are in line with customer's requirements.
