Raymond Mill

[Introduction] A mill with independent production system.

[Capability] 3-22t/h

[Application] Various non-flammable and non-explosive mineral materials with hardness below 9.3 mohs and humidity below 6%, such as cement, talc, feldspar, quartz, slag, mica, calcite, limestone, barite, potassium sulfate, bentonite, etc.

[Improvement] Unique air self-circulating system, equipped with advanced dust collector, the grinding roller assembly is connected with high-pressure spring through tie rod, which avoids the loss of large material to equipment. The elastic connection between the main engine and the flour separator reduces vibration and noise and improves the service life of the equipment.

Advantages:

1. Raymond mill is vertical structure, just need small area.
2. The particle size of the finished product is uniform, and the pass rate of screening reaches over 99%.
3. The transmission device adopts hermetic gearbox and pulley, which ensures smooth transmission and reliable operation.
4. Important parts are made of high-quality steel. The machine has good wear resistance and reliable operation.
5. The electric system adopts centralized control. The mill workshop can basically achieve unattended operation, and maintenance is convenient.
6. The grinding roller assembly is connected by a tie rod and a high-pressure spring. The force generated avoids the loss of large material to the equipment. The elastic connection between the main engine and the flour separator reduces the vibration and noise, and improves the service life of the equipment.
7. The roll grinding device adopts overlapping multi-stage seal with good sealing performance.
8. Unique air self-circulation system, equipped with advanced dust collectors.
9. High density and high precision impeller devices greatly increase the output of finished products under the same power. The centrifugal induced draft fan with high efficiency and energy saving greatly improves the efficiency of induced draft fan. Convenient and fast impeller adjustment device improves the precision of finished products.

Structure:
Material is evenly and continuously fed into the machine for grinding. The grinded powder is taken out by the circulating air flow of the blower and classified by the classifier above the raymond mill. The powder conforms to the specifications goes into the cyclone dust collector. The air flow is flowed into the blower by the return duct at the upper end of the cyclone receiver. The whole air system is closed cycle, and most of the air flow is in the negative pressure state. Because the grinded material contains water, it evaporates into gas during grinding and leaks into the air duct under negative pressure, which leads to the increase of air flow in the circulating air duct. The increased air flow is introduced into the dust removal box from the residual air duct of the blower and the main engine, and a number of fine powder brought with the air flow is collected in the dust removal box, and the gas is discharged into the atmosphere from the exhaust pipe.
