Rod mill is named as the grinding media of its cylinder is steel bar,people usually call this type of machine MB model.Rod mill has two types of dry and wet respectively,and user could choose the right one based on their own actual situation.

Features:
1.To save power：Rod mill has 40% power saving than traditional crushing equipment,particles are much more uniform.Comparing the characteristic of finished products of rod mill and ball mill，they are almost same in open work of rod mill and close work of ball mill.
2.Adopt advanced materials-access controllable rod mill technology,equipped with a suitable abrasive material grinding system based on actual user,change surface-contact of traditional ball mill into line-contact,make discharged materials more uniform,and make production more higher and also more suitable for different hardness(Mohs hardness of 5.5 to 12)ore.
3.The fineness of discharged materials can be adjusted：change particle size through simple adjustment，equip-in fineness controllable device,and the screening device is available for discharged materials,there are two pass-guard to ensure neither excessive grinding nor substandard particles mix into finished products.The rod mill products feature is relevant to particle ore of rod grinding situation.When the rod hit against the ore,coarse particle is hited firstly,then smaller mineral particles is under grinding to reduce the risk of excessive-crushing.When rod turn rising with lining plate,fine particle falls through bars sieve and coarse particle is blocked,it is conductive to click coarse particle into pieces,and also make coarse grinding media concentrate on hitting area.Therefore the rod products is more uniform and less over-crushing.

Working Principle:
According the discharging type,wet rod mill could be divided into three type of overflow type rod mill,open-type rod mill and peripheral type rod mill,overflow type rod mill is the most common one.As the first class open grinding equipment,rod mill is widely used for first class grinding equipment of concentrator,artificial sand stone and electricity sector of chemical plants.The rod mill rotation is based on deceleration motor and large gear deceleration rotation or through large gear deceleration rotation which driven by low speed synchronous motor,and then drive rod mill cylinder rotating.Steel bar,the grinding media is installed in cylinder,media is promoted to a certain height because of the joint action of friction and centrifugal force,and is dropping or falling off.The grinding materials are continuously feeding into the cylinder through inlet of rod mill,crushed by steel bar and discharge the finished products out of rod mill by overflow and continuous feeding strength then go to the next process.
