XMB Laboratory Rod Mill

XMB Laboratory Rod Mill

XMB Rod Mill is applicable to lab for wet fine grinding of ore and other materials. Steel ball may be used instead of steel rod in the ball mill.

  1. Description

XMB Rod Mill is applicable to lab for wet fine grinding of ore and other materials. Steel ball may be used instead of steel rod in the ball mill. In rod grinding, fine product particle fractions are relatively uniform with rare occurrence of over grinding and high efficiency. It is also applied in labs for processing and fine grinding for the industry of metallurgical, building material, chemical, light industry, coal, water electric power, agricultural, artificial heavy concentrate in geological testing, mineral processing, etc. The product is produced by the only enterprise designated by the former Ministry of Geology and Mineral Resources, in compliance with the Industrial standards.

  1. Main Structure

Drum of spherical graphite cast iron and big belt pulley are connected through screws. At one end of the drum is an opening and at the other end of it is a hollow journal. Both ends are respectively supported on a pair of rollers and a main bearing. The main bearing seat and bracket are respectively on the bearing plate which can rotate for 180°. The bearing plate is installed on the frame with two bearing pedestals. The bearings control the handle and positioning plate through rotation. Horizontal deflection of 22.5°, 35°,67° and 90°can be applied to realize ore loading, ore discharging, tamping rod, filling antirust limewater, etc.

There is plug of feed mouth on the right of the drum and there is cover of discharge mouth at the end of the machine. During the operation of the machine, use a special-purpose spanner to tighten the bolts, to get the sealing rubber gasket on the cover of discharge mouth to tighten the bolts for three or four rounds so that the cover can go backward for 6~10mm. Ores can be discharged without the cover being removed. At the end of the discharging mouth is installed a slurry cover, which completely avoid splashing of slurry during the washing rotating branch within the designed working speed.

The motor and intermediate shaft are installed below the bearings, so as to realize balance with the weight above. The tension of belt can be adjusted for every grade of the driving two-grade belt pulley, to ensure appropriate grilling speed.

4. Installation, Application, Maintenance

The pulleys of 67 rod mill are respectively adjusted through the T-groove slide on the supporting plate and the slot on the seat board of the intermediate shaft.

The pulleys of 68 rod mill are respectively adjusted according to the following method:

  1. To adjust drum belt, what should be done mainly includes the adjustment of vertical position of intermediate support. However, in order not to affect the tension of motor belt, corresponding adjustment shall be made of the adjusting bolt

△L — Required adjustment amount (needing to tighten as is shown in the figure)

S1 – Adjustment amount of intermediate support (moving downward as is shown in the figure)

S2 – Adjustment amount of adjusting bolt (moving downward as is shown in the figure)

  1. To adjust motor belt, what should be done mainly includes the adjustment of vertical position of screw, to get the intermediate shaft to revolve around intermediate support to a certain position. However, in order not to affect the tension of drum belt, corresponding adjustment shall be made of the intermediate shaft for compensation.

To match the use of various kinds of receiving containers, folding receiving carriage can move upward or downward. The electric equipment of the machine has been installed. When the power and earth wire are connected, the machine can be operated according to instructions.

Please tell your requirements: capacity, raw material, max feeding size, output size, then we will design the ball mills for you.
