With the development and advancement of technology, more and more rod grinding mills are widely used in the industrial fields. Henan Hongxing Mining Machinery Co., Ltd. produces a variety of rod mills, and the rotary rod mill is its flagship product.

The rotary part of the rotary rod mill is a barrel which is welded by the steel plate. Both ends are respectively connected with the feeding hollow shaft and the discharging hollow shaft, and they are horizontally supported on the two main bearings. Spirals are installed in the feeding hollow shaft and the discharging hollow shaft. Through the big gear ring which is fixed on one end of the barrel, the small gear drives the rotation of the rotary part through the reducer and the motor.

 A liner is installed in the barrel, which can be used to protect the barrel and take the steel rod to an appropriate height so that improve the efficiency of sand making. In order to prevent gray leakage and the water leakage from the liner bolt hole, you should tightly wrap two rings to ensure the seal. 

Rotary Rod Mill

When you install the rotary part of the rotary rod mill, you should pay attention to the following points. First, before assembling the cylinder and the hollow shaft, you should check the barrel. The ovality tolerance should not be greater than 5 mm. Second, having been assembled the main bearing and the anchor bolts, you can install the barrel on the main bearing. Third, after the cylinder being put on the main bearings, you should check the elevation at both ends. In terms of the generatrix measurement of the hollow shaft, the relative elevation difference should not be greater than 1 mm.

Henan Hongxing Mining Machinery Co., Ltd. has many years' production experience and it is committed to producing high-quality wearable special rod mill. After many years' research and development, the experts in Henan Hongxing Mining Machinery not only learn and absorb foreign advanced technology, but also actively create products and vigorously develop domestic rod mill, and finally develop a new type of rotary rod mill. The rotary rod mill has made great contribution to the development of the domestic rotary rod mill.
