The Application of the Vibration Mill in China

There are dozens of countries which use  more than l OOO vibrating ball  mills, and has been done the basic serialization. Vibration mill products  of Chinese can be divided into  the single simple type, the binocular-type and three drum three kinds of basic models, the simplified volume is 200 a l 000 L,. On the basis of the tube vibration mill, Technical University of Berlin developed a rotating chamber tube vibration mill. compared with the conventional vibrating mill, this kinds of mill's processing capacity increased by 0.5-1 times, the unit energy consumption decreased by 20% -40%, get rid of the conventional tube vibration mill's disadvantage that the  diameter of the arguments can not exceed 650 mm. The main problems of the vibration mill is  stand-alone processing capabilities low and can not meet the requirements of mass production, and the development of large-scale vibrating mill has caused great difficulties in the mechanical,the vibration mill springs and bearings are easily damaged; when the raw water requirements is more than 4% -5%, the mill output will be greatly reduced .
The vibrating ball mill of the Chinese production can be divided into  MZ and MGZ -1 type series.
(1) the MZ-type vibration mill. Figure 3.3 -25 shows the structure of this type of simplified mill. The spindle motor rotate by the coupling of tires make with the eccentric weight exciter eccentric with focusing on the centrifugal force generated when the spindle rotation Simplified elastic support vibration. Simplified vibration's frequency depends on the spindle revolutions and change the weight of the angle which can adjust the amplitude size.Simplified wall was installed the rubber liner to reduce noise. To reduce iron contamination, the use of rubber or polyurethane of the ball media can be outsourced. Simple wall with water cooling device can control the heat generated due to medium-high-speed vibration Simplified overheating.
(2) MGZ -1 type vibration ball mill. The machine is a dual-Simplified parallel arrangement, the gear is similar to the MZ-type vibration mill. This mill is characterized by large amplitude in order to improve the vibration intensity (up to 19 g), the elastic system uses a special air spring. 4 spring design in the structure of Bu mutually inclined at an angle to ensure that the trajectory of the machine round. due to the vibration intensity, The vibrating mill grinding effects is good,  the ore particle size is up to 25 mm. MCZ - 1X/80 type vibration mill main technical parameters.
(3) pairs of Jane Parra (Palla) vibrating ball mill. Figure 3.3 - 27 is the Palla type vibration mill structure to indicate that it has upper and lower set of two tubular Simplified l Simplified between two to four supporting board 2 is connected;
support in the rack ; in the middle of the bearing plate equipped with a spindle bearing, spindle Bu fixed eccentric weight, the motor through a universal coupling drive spindle. Palla-type vibration of the small size of the mill two eccentric weights, the large size of four eccentric weights, each eccentric weight of the composition of two, during which the mutual angle is adjustable to adjust the size of the eccentric force. Eccentric force tubular Simplified and bearing plate vibration rubber spring. Usually do not set in the simplified both ends of the feeding part and the part of the nesting, but based on operational need can be located in the Simplified Central.Palla-type vibration mill diameter and length up to 200-650 mm and 1 300 ~~ 4 300 mm, the maximum motor power of 200 kW. Made in Germany, is a vibration mill to use more and a broader model.  Features: without screening superfine material, production is safe operation, we simply need to adjust the amplitude, vibration, diameter, grinding media, fill rate, and control of the feed to get the desired product size, and easy to adjust these parameters . But these  diameter is easy to adjust, with the increase in the effective cross section, low-energy region  accounts for a larger proportion.
