Product Description

Pneumatic Roller Mill

The pneumatic roller mill is an ideal grain milling machine for processing corn, wheat, durum wheat, rye, barley, buckwheat, sorghum, and malt.  Widely used in Flour Mill, Corn Mill, Feed Mill, and so on. The length of the milling roller is available in 500mm, 600mm, 800mm, 1000mm, and 1250 mm.

The roller mill can automatically adjust the opening degree of the door of the feeding mechanism. First-class pneumatic components are used to achieve reliable movement.
It can be installed on the second floor for convenient operation or on the first floor to save space. Different surface parameters correspond to the different grinding passages and different intermediate materials.

Feature
1. As a flour mill, the MMQ/MME type grain roller mill is perfectly designed for the flour milling industry.
2. The milling rolls are running on self-aligning SKF (Sweden) roller bearings housed on a carbon steel beam and located on shock absorbers. Thus the machine vibration can be greatly reduced and the machine operation could become very quiet.
3. The structure of the main base of the roller mill is made of cast iron which is designed for heavy loading capacity. Other frames are welded and appropriately processed by high-quality steel plates for eliminating mechanical stress. This special design can further guarantee limited milling vibrations and noise-free operation.
4. The main drive mechanism between motor and fast roller is the 5V high tension belt, while the transmission part between milling rolls is a sprocket belt which could absorb the vibration and noise to a great degree.
5. The milling rolls of the roller mill are engaged by pneumatic SMC (Japan) air cylinder units installed on both sides of the machine.
6. The milling roller is horizontally installed. The roller set bears all the operational pressure.
7. The advanced scraping blade cleaning technique can ensure the rollers’ desirable milling performance.
8. A built-in aspiration channel is available in the roller mill.
9. The feeding system of this wheat grinding machine is available in two types:
(1) Pneumatic servo feeding system
It can automatically adjust the opening degree of the door of the feeding mechanism. First-class pneumatic components are used to achieve reliable movement.
(2) Automatic Siemens (Germany) feeding roll system with micro PLC
This system adopts the frequency conversion technique to adjust the feeding roller’s speed automatically according to the material quantity, ensuring that the materials can be fed into the rolls evenly and continually. A high-quality speed-reducing motor and frequency converter has been adopted for ensuring accurate movements. The micro PLC control box is located in the main MCC cabinet room of the roller mill.

The material level is controlled by the level sensor plate

The sensitive flow control and the accurate feeding reaction of the feed roller avoid frequent engage and disengage of grinding rollers, which is beneficial to lengthen the grinding roller’s service life. The material after girinding will flow down by gravity or be lifted by suction.

Feeding Roller

The feeding roller is controlled by cylinder whose reaction is sensitive.

Roller

Double metal centrifugal casting, high strength and good wear resistance. 
Unbalance of the dynamic balance ≤ 2g. 
Total radial run-out < 0.008 mm.
The shaft end is treated with 40Cr and the hardness is HB248-286.
Hardness of roller surface: Smooth roller is Hs62-68, tooth roller is Hs72-78. Besides, the hardness distribution is uniform, and the hardness difference of the roller is ≤ Hs4.

Blackening treatment

Blackening treatment is applied to belt pulley and other castings, which keep it from rust. And easy disassembly
