subject: Difference Coming From Comparison Of Two Type Rod Mill [print this page] Brief Introduction Brief Introduction
Dry rod mill is named as wet rod mill opposite; it is mainly used in building materials, chemical industry and industrial milling operation. Be with analyses machine, dust collector and other equipments assembling industrial flour production line. Products size is adjustable; system is stable, no wearing parts, and most widely using.
Wet type rod mill is most mainly used in mineral processing industry, also in glass and other building material industry. Wet rod mill is named as wet-processing production. In the production process, a material mixed with water is poured into pin crusher for grinding. Under the action of water, the flow of materials is good enough to get a higher processing capacity. Spiral classifier, hydro cyclones, high frequency screen and other grading equipment are common used for controlling particle size.
Features of Dry rod mill and Wet type rod mill
1.Transmission adopt rolling bearing instead of sliding bearing, great reduce the friction, ease start and power saving a lot.
2. Cone design of discharge end, not only increase the volume, but also force cone side materials separate from steel ball, the closer of out-put end, the smaller diameter of steel ball, and then increase the effect of repeated grinding;
3.The using of circular trench liner increasing the contact surface of ball and mineral ore, enhancing the grinding and capacity of mineral ore, reducing energy consumption. ball mill:http://www.hx-crusher.com/
4.Using the whole frame to facilitate civil constructionone construction of a concrete foundation is availableand equipment installation.
Working principle of Dry rod mill and Wet type rod mill
The working principles of Dry rod mill and Wet type rod mill are the same, so we only take wet type rod mill as an example.
Wet type rod mill is a horizontal cylindrical rotating device, outer gear, two chambers, tumbling box. With the hollow shaft screw, materials evenly run into the first chamber through feeder device. The first chamber has ladder liner or corrugated liner, different specification steel ball is inner-built too, Steel ball is lifted to a certain height and then fall off because of centrifugal force based on rotating cylinder, then make impact and grinding materials. After coarse grinding in the first chamber, materials enter into the second chamber through single-compartment plate, with inner flat plate and cement miller's impact effect; materials would be under further grinding. Powder is discharged through discharging grate plate, then grinding processing is finished.
