As we all know, Latin America is rich of minerals. This place is full ofmountains, rivers, and forests, which are the rich areas of volcanic rocks,basalt, river pebbles, and coal. The reserves and production of iron, copper,gold, silver, and other metallic minerals range first in the world. Therefore, mining,crushing, grinding, and processing equipments are widely used in Latin America.

Kefid Machinery Co., Ltd. is a leading and pioneering enterprise with the mostadvanced international level in R&D, manufacturing and selling oflarge-scale crushing & screening plants and industrial milling equipments.In the past two years, the sold machines of Kefid in Latin America are mainlycrushing equipments, while grinding machines are relatively fewer. However,grinding mills has a very large potential market in America. So, let’s learnmore about roller mills and ball mills’ usage in Latin America.

First,people in Latin America are very familiar with ball mills for a long time. Ballmills belong to traditional grinding equipments, widely used in metallicminerals processing, chemical fertilizer, glass, ceramics, cement, newconstruction materials and silicate products industries. There are wet and drymilling methods. Ball mills have many advantages, such as diverse optionalmodels, stability, suitability for hard materials, etc. However, they also havemany disadvantages, like lower production, higher energy consumption, andcomplex process.

Second,roller mills have advantages over ball mills to grind limestone, andesite, andmarble, while ball mills are still their first-choice in Latin America. Rollermills include vertical and dry milling. They rely on the gap between millingroller and milling ring to grind and select powder through air machine andclassifier.

Rollermilling machines of Kefid consist of trapezium mill, high pressure mill, Raymondmill, MTW series trapezoid mill, micro powder mill and vertical grinding mill.Their advantages include:

I. Small occupiedarea and low investment cost because of its vertical structure;

II. Highefficiency, energy saving, uniform particle size, easy to adjust;

III. Simpleoperation, easy maintenance, safe and reliable;

IV. Environmentalprotection, low vibration;

V. Integratedsystem, from crushing, feeding to selecting, no waste of manpower.

Therefore,roller mills can replace ball mills to process powders below 6 hardness, that10 – 400 meshes. Micro powder mills can even grind materials into 300-3000 meshes.

Ourcompany’s roller mills have sold to Egypt, Russian, Columbia, and Kazakhstan.Welcome to visit our company.
