first-grade quality improved limestone raymond grinder mill

GUIKUANG is the first raymond mill manufacturer and one of largest production base since 1973. first-grade quality improved limestone raymond grinder mill   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:     Benefits&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.     3. Main Technical Parameters:       Technical Parameters 1. Main Unit

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       Workshop & Warehouse Being  an   ISO 9001 : 2008  certified  unit,    systems    and procedures  are   well   defined  and  monitored  closely  at   all  stages of the production process.   7.Installation Sites       Installation Sites Since 1973, more than 8000 grinding mills have been installed in domestic and overseas regions:       8. All Kinds of Models for Different Requirement:    More Models There are more models to meet users'  different capacity requirement: Note:  1.The specifications in the above file are for reference only. We reserve  the right to modify or change them as required. 2. The above capacity is based on limestoe    9. Technical Service:    (1) Free design for the production line flow chart diagram according to the site. (2) Provide technical parameters of auxiliary equipment. (4)  if buyers need to adjust the layout, free technical support is available. (5)  During running period, if buyers want to update the equipments, only cost is charged.     10.After-sale Services: (1) Engineers are available to send to assist installing and debugging the equipment.
