Alumina grinding media balls/Grinding Steel Ball/Grinding Media
Ball trader Product DescriptionJunda
ceramic ball refers to alumina powder as raw material,
after ingredients, grinding, powder (pulping, mud), forming,
drying, firing and other processes produced, mainly as grinding
medium and widely used ball stone. Because the content of alumina
is more than 92%, it is also called high aluminum ball. Appearance
is white ball, diameter of 0.5-120mm.Product Parameters Junda

ProcessAccording to the size of the rolling method and machine
pressing method, 0.5-25mm are generally rolling ball large ball
25-90mm are generally machine pressing ballMachine press ball
process brief: powder and various additives after mixing spray
granulation, and then the powder added to the metal mold
prefabricated into balls, and then the billet after the release of
the cold isostatic pressing treatment to obtain the ball billet,
the use of this process to prepare the billet caused by high
density, sintered ceramic ball high density, good quality.It is
generally used to produce large size and high quality grinding
balls with diameter greater than 10mm.Brief introduction of rolling
ball process: the powder and water, adhesives, plasticizers,
lubricants, etc., are added to the mud mixing machine to form mud
by stale plastic mud material, into the mud extruder extrusion made
of strips, and cut length and diameter of the mud section, and then
into the ball rolling machine to make billet. Product
ApplicationsGrinding, polishing, etcIt is widely used in the
precision processing and deep processing of all kinds of ceramics,
enamel, glass and thick and hard materials in chemical plants, as
the grinding medium of ball mill, tank mill, vibration mill and
other fine mills.Product FeatureWear small, high hardness,
corrosion resistance, impact resistance, economic and practical.(1)
High wear resistance: the wear resistance of alumina grinding
porcelain ball is better than that of ordinary porcelain ball. Can
greatly extend the service life of the abrasive body.(2) High
purity: when the grinding porcelain ball is running, it will not
produce pollution, so it can maintain high purity and improve the
stability of the grinding effect.(3) High density: high density,
high hardness and high grinding, so as to save the grinding time
and expand the space of grinding, can effectively improve the
grinding effect.(4) high strength, high temperature resistance
(temperature resistance of about 1000ºC, 1000ºC or more for a long
time is easy to stick), high pressure resistance, acid and alkali
corrosion resistance (not in oxalic acid, sulfuric acid,
hydrochloric acid, aqua Wang and other environments), thermal shock
stability, stable chemical properties Our AdvantagesThe
company chooses mountain aluminum alumina as the basic raw
material, with high purity, less impurities and stable quality.
Implement Kanban production, the whole production process can be
controlled and traceable. Each batch of products are selected for
strict inspection, process and result testing to ensure the
stability of the finished product performance, excellent quality.
Ensure alumina content, ensure low wear, adequate supply, timely
and convenient delivery. Company ProfileLocated in Jinan City,
Shandong Province, Jinan Junda Industrial Technology Co., Ltd.
