The working principle of the rod mill: the rod mill relies on the pressure of the rod and the grinding and peeling force to grind the ore. When the rod hits the ore, the first is to break the coarse particles, and then grind the smaller ore; the rod is in contact with the rod, and the ball is in contact with the ball, so when the rod rotates along the barrel wall When it rises, it is sandwiched between coarse particles and acts like a bar sieve to allow fine particles to pass between the joints. This also helps to crush the coarse particles and concentrate the coarse particles in the place where the grinding media strikes. Therefore, the rod mill is optimized for selective grinding, and the product has a uniform particle size and less pulverization.
There are roughly three types of rod mills (the range of use of rod mills):
1. When two-stage continuous grinding is used, if the first section is ground from 20-6mm to 3-1mm, when the rod mill is used as the first section of grinding equipment , the production capacity is larger and the efficiency is higher.
2, tungsten, tin ore and other rare metal ore re-election or magnetic separation plant, in order to prevent the "smashing" the harm caused, often using rod mill.
3, in some cases can be used to replace the short-head cone crusher for fine crushing.
It can be seen from the above that the application field of the rod mill is quite extensive, and it can be used not only as a grinding equipment but also as a crushing equipment.
Mini Desktop Cnc Router
The main feature of the desktop cnc router is the small and simple structure under the special spindle design. Various materials can be applied by the machine, such as PVC, Acrylic, wood, PCB, even some soft metal like aluminum and copper. Besides, all the machines are equipped with Mach3 controller. In addition, the machine can achieve the performance of good resolution and less noise with ball screw.
Product Description:
2. UTECH 3040 3axis 800W - is a professional mini- size machine with working area 300 x 400 mm (30 x 40 cm). Has the most powerful ruler in the spindle: XYZ. The spindle has a water cooling - it provides reliability and long service life.
3. Difficult to think of the problem, which cannot handle this car. The only limitation to the possibilities in front of large and heavy brethren: Stage size and speed of processing, and in the aggregate: functionality, compactness and price - out of competition.
4. The machine can easily be placed in a small workshop or home. Will apply for relief 3d- treatment (three-dimensional objects , reliefs, souvenirs, cliche) , engraving (personalization items , creating labels , jewelry , engraving PCBs ) , all types of cutting (letters and labels , signs , models ) , drilling.
Product use:
B. Graphite electrode processing, carving PCB circuit board, wood model mold crafts.
C. 3d sculpture of aluminum alloy, copper and other metal materials according to the feed rate.
D. Can be used as a simple three-dimensional numerical control platform, such as numerical control point glue, numerical control positioning, metal marking.
