425-2500 mesh grinding mill plant

Micro Powder MillMW series three-ring & medium-speed micro-powder grinding mill is designed basin on our 20 years’ manufacturing experience, adopt the advanced Swedish machine manufacturing technology. It is a new type of mill for processing super fine powder, which is with test and improvement for more than 20 times. It is the latest type of micro powder grinding mill.

MW series three-ring medium speed micro-powder mill is designed to get fine and super fine powder. It is mainly used to process more than 200 kinds of non-inflammable, non-explosive and brittle materials with Moh’s hardness under 6 scales, such as calcite, chalk, limestone, dolomite, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, tablite, ceyssatite, barite, gypsum, alunite, black lead, fluorite, phosphate rock, potassium ore, floatstone etc.

European Grinding Mill

mtwEuropean Tech. Grinding Mill also called MTW Series Trapezoid Mill, that is our lastest grinding machine with several patents, optimized based on our suspension mill 9518, absorbed european manufacturing technology, meets clients requirements of excellent fineness, reliable performance and favorable price.

OUTPUT SIZE: 1.6-0.045 mm, the fineness is 0.038mm

PRODUCTION CAPACITY: 3.5-25T/H

PERFORMANCE

Kefid is specialized in producing large scale industrial mills. These grinding mills are used in thermal power and steel companies’ limestone desulfurization, lime milling, crushing and screening. MTW series Mill is the world’s largest industrial milling machine and the world’s most advanced European-style trapezoidal milling machines is is particularly applied to limestone, lime crushing and milling of large production.It is widely used in steel mills and thermal power plant desulfurization process of milling,and the ratio of desulfurization can be higher than 92%. Its maintenance is convenient and results are obvious. It is exported to European , Asian and African countries and more regions. It is called “Chinese king of mill” by Power plants and iron and steel enterprise, and makes contribution to the world’s environment protection.

Micro Powder Mill

Micro Powder Mill is mainly used to grind non-flammable, non-explosive non-mental materials with medium and low hardness, temperature below 6%, and Mohs hardness below 9 grade, such as processing gypsum, calcspar, talc, and other materials used in painting, pigment and cosmetics industry. Compared with jet mill, It is economic-cost, high-capacity, and the spare parts just need to exchange once a year.Environmental and less pollution. High efficient pulse dust removing device is adopted, which can guarantee little dust pollution of the whole set of equipment. Muffler and silencer room are allocated, which will reduce dust pollution and noise and meet the national environment protection standard, and protect the surrounding environment.

Micro Powder Mill Features:

1.Low investment cost. With same fineness and motor power, it invest less comparing with airflow mill, stirring mill, ball mill, which is of low cost, short recovery period and twice more production capacity.
2.High powder outlet ratio. With same product fineness and energy consumption, capacity is 45% higher comparing with airflow mill and stirring mill.
3.Less loss of wearable parts, long life span. All wearable parts are of high-quality abrasion resistant materials both at home and abroad, which has longer life span than ordinary mill, generally more than one year.
4.High security and reliability, running safely and stably in the grinding cavity. Comparing with ordinary mill, the super fine mill has advantages of no rolling draft, no bolts. Thus, there is no problem of weariness of drafts and other seal parts, which can avoid bolts loosing and machine damage.
5.High fineness of final product. Final fineness can reach d97≤5μm in one time.
