Raymond grinding mill for graphite



Graphite archaically referred to as plumbago, is a crystalline allotrope of carbon, a semimetal, a native element mineral, and a form of coal. Graphite is the most stable form of carbon under standard conditions.

Graphite properties, high temperature resistance, electrical conductivity, thermal conductivity, lubricity, chemical stability, plasticity, thermal shock resistance。

Natural graphite is mostly consumed for refractories, batteries, steelmaking, expanded graphite, brake linings, foundry facings and lubricants.

For 80-400 mesh graphite raymond grinding mill, Guilin hengda HD series high efficiency raymond grinding mill is a good choice, it breakthrough the bottleneck of the grinding mill, the production is 20-30% higher than traditional raymond mill, The increase mechanism of linkage pressure of the rollers, which greatly prolongs the useful life of the equipment and increases the capacity by 20% under the same power. With the original roller assembly, the oiling time increased 6 – 15 times, achieve the application of oil once, use for 30-45 days.Higher Accuracy powder Classify, without coarseness missing, e accuracy is 80-600 meshes. The classify efficiency reached 99%. HD series has the advantages of high production, high qualification rate Low noise and vibration in grinding of the 325-400 meshes.
HD series high efficiency raymond grinding mill specifications:
Max feeding size: ≤35mm
Main motor power：45-315KW
Capacity: 1-60t/h
Final product size: 80-400 mesh
Applications : For non-metallic minerals with a Mohs hardness of 6 or less and moisture content of 6% or less, it has a high productivity and high grinding power, such as talc, calcite, calcium carbonate, dolomite, , Kaolin, clay, graphite, , zircon sand, bentonite and other non-metallic minerals.
Grinding process
Stage 1: Breaking
Graphite is broken by a crusher to a fineness (≤20mm) that can enter the mill.

Stage 2: Grinding
The broken small pieces of graphite are sent to the silo via a lifting machine, and then evenly and quantitatively sent to the grinding chamber of the mill via a vibrating feeder for grinding.

Stage 3: Grading
After grinding, the graphite powder is graded by a separator. Unqualified powder is graded by the separator and returned to the host for re-grinding.

Stage 4: Collecting powder
The powder with fineness follows the air flow and enters the dust collector for separation and collection. The collected finished powder is sent from the conveying device to the finished product silo through the discharge port, and then is uniformly packed with powder tankers or automatic balers.

How much does it cost to buy a grinding mill production line

图片
Guide: For the purchase of a grinding mill  production line, in addition to concern   about whether the production line can meet the production needs, is the reference to its price, then what is the price of a grinding mill production line? The grinding mill production line is mainly for the grinding of materials. This production process contains many types of equipment. Therefore, a production process requires a large cost. This cost input is a relatively large part of the cost of the process. Therefore, it is an important reference for customers to purchase this process. Here is the price issue of the mill process. For the grinding mill production line, because it contains a large variety of equipment s , the choice of different equipment will affect the price, in addition, the difference in production requirements and the difference of manufacturers will also cause price differences . The impact  of these aspects of the price of the process is mainly as follows:...

Raymond Mill common faults and solutions

图片
Guilin Hengda   h as  summarized the various failures that Raymond Mill  has encountered during its use  according to the comprehensive R&D production experience and customer feedback, and provides related solutions  for your reference: Common faults  1 : No powder or low yield. R reasons: (1) The powder locker is not adjusted properly and the seal is not good , resulting in powder sucking. (2) B lade wear  terribly , material can not afford shovel. Solution s : (1) Check and adjust the lock of the powder locker. (2) Replace the blade. Common fault 2 : The finished powder is too thick or too fine. R eason s : (1) The blades of the analyzer are seriously worn and do not have grading effects. (2) The air volume of the fan is not appropriate. Solution s : (1) Replace the blades, and properly turn down  the air intake of the fan to solve the rough. (2) Too fine should increase the imported air volume. Common fau...
