The advantages and disadvantages of the horizontal rice mill

Advantages of horizontal rice mill

1. Smooth operation. The bearing only bears radial force, and the bearing stress and torque of the whole machine produced by the unbalanced force are small. The horizontally installed white rollers do not have high requirements for manufacturing and assembly; the technical requirements of the corresponding structural parts are general;

2. The volume and machine weight per unit output are small. Due to the large axial driving force and the high flow rate of rice grains, under the same material flow rate as the vertical rice mill, the diameter of the white roller and the annular area of ​​the white room are both small, and the volume and weight of the whole machine are small. Lighter, lower manufacturing technology requirements, and lower cost;

3. It is convenient to disassemble and assemble the sand roller in the horizontal direction of the rice mill, saving time and effort;

4. The rate of rice production is high, and the spiral groove makes the density of the rice grain fluid uniform over the entire length of the whitening room, and the tumbling movement is good, and the parts of the rice grain are evenly milled;

5. The two white-rolling rollers are very convenient and reasonable to be combined coaxially or off-axis in one rice mill.

Disadvantages of horizontal rice mills

1. Gravity affects the centrifugal acceleration of rice grains, and makes a difference between the upper and lower parts of the whitening room, which affects the uniformity of the whitening degree;

2. The number of rice knives is small, the material is hard, and some are not easy to adjust. For example, the fixed rice knives in the middle and lower parts need to be stopped and adjusted. Although the steel rice knives are wear-resistant, they are easy to damage the rice grains and increase the rate of broken rice;

3. Bran is easy to accumulate in the upper part of the whitening room;

4. After the spiral groove is worn, manual chiseling is required, and the quality after repair is different from person to person; the sand roller is $ 35 knots. After wear, it cannot be adjusted or partially replaced, and the maintenance cost is high.
