high output energy saving quicklime vertical roller mill machine


1. Brief Intruduction:


Raymond  grinding mill is mainly used in  chemical industry such  as grinding  glass, rubber,   pesticides, enamel, 

paint,  phosphate fertilizer, paper.  Hardness below  seven  Moh’s  hardness   following    humidity below   6%  non-flammable and   explosive  materials.Such as: talc, barite,  calcite, limestone, manganese oreiron ore ,   chrome ore, quartz, gypsum, bentonite,   etc, below are some material in application:


2. Technical Advantages:




1.Host Improved -- The increasing grinding space and force ,achieved by heightening   roller & ring and enlarging blade , increase production capacity.
 2. Reducer Improved -- Compared with past single rotating speed,the modified reducer’s rotating speed can be adjusted optionally as per requirement,production capacity increa-sed by improving grinding force.
3.High Classification Accuracy -- Classifier adopts built-in large taper blade turbine classifier. The outlet fineness can be adjustable from 80-600 mesh.
4.Cyclone Collector Improved -- More effective collecting efficiency is achieved by adopting super large cyclone collector.
5.Air Blower Improved -- It is equipped with high pressure air blower . The wind pre-ssure is doubled and  pneumatic conveying ability is improved greatly.
6. High Capacity & Low Power Consumption -- 30% production capacity is improved compared with 4R3220’s.

  4. Production Process




Production Process

Grinding Process of Main Unit:


The motor’s power is driven to the decelerator’s output torque, by way of the coupler, drives the center shaft’s plum-shape holder to make a circumference revolution. In the mean while, the rollers rotate due to their mutual friction. And caused by the centrifugal force, these rollers sway outward, pressing the ring tightly. In the course of its turning around, the shovel blade, which is fixed at the intersect for the lower part of the holder and the roll, shovels the ore to the point between the roll and the link, forming an ore-cushion coat. As the rolls keep on rolling, crush and pulverization are thus completed.






 5. Details Decide Quality

(1) Jaw Crusher

 a. The body shell is whole casting by our own foundry. Much more stable than welding shell.

 b. Thickened shell gets longer service life. 3, Simple and reasonable structure

Note: some jaw crusher of other supplier  is welded with seperate pieces. This makes the structure less compact.


(2) Foundation Bolt

 The long foundation bolt can reduce vibration and make the machine more stable when then machine is  running, thereby it will prolong service life.

Note: some supplier adopts expansion screw insead of the foundation bolt. This increases the vibration during the machine is running. 


(3) Large Base of Main Unit

 a. Large base makes the machine more stable during running.

 b. The design of tangential airflow inlet make the airflow from air blower into the chamber more easier.The design  take full advantage of the airflow and save energy  consumption.

Note: some supplier only weld some steel onto the inside wall of main unit. This reduces the price but weaks the stability and performance of the mill.


 (4) All shafts

 Central Axis is core component for each machine,we have strict quality control for this:

a. First step --The central axis will be preliminarily rough machined by lathe

b. Second step -- Heat Treatment Quench and elimit its internal stress to make the central axis more tenacious and stable

c. Third step -- Finsh turning

d. Last step -- To mill bearing position by grinder

 Note: in order to reduce cost, some supplier would not to take the above full steps.





 6. Workshop & Warehouse
