LM Vertical Mill

High drying efficiency, Low running cost, Good environmental effect

LM Vertical Mill integrates crushing, drying, grinding, classifying and conveying together, and it is specialized in processing non-metallic minerals, pulverized coal and slag. Its coverage area is reduced by 50% compared with ball mill, and the energy consumption is saved by 30%-40% similarly.

Applications: Cement, coal, power plant desulfurization, metallurgy, chemical industry, non-metallic mineral, construction material, ceramics.

MTW Trapezium Mill

Large capacity, Low consumption, Environmental friendly

MTW European Trapezium Mill has a large market share in the grinding industry. Whether bevel gear overall drive, inner automatic thin-oil lubricating system or arc air channel, these proprietary technologies makes machine advanced, humanized and green.

Applications: Cement, coal , power plant desulfurization, metallurgy, chemical industry, non-metallic mineral, construction material, ceramics.

nihil molestiae consequatur

Little abrasion wear, Long service life

Based on 30 years of development experience of grinding equipment, LM Heavy Industry produced LUM Series Superfine Vertical Roller Grinding Mill to make ultra-fine powder. The grinding roller doesn't contact with millstone usually, which makes abrasion little and service life longer.

Applications: Superfine dry powder of none-metal ores such as calcite, marble, limestone, coarse whiting, talc, barite and dolomite and so on.

Simulating the Bond rod mill grindability test ScienceDirect

Jan 01, 2012 The standard rod mill grindability test (Bergstrom, 1985) was conducted with four ores, ranging from very soft to very hard. Briefly, the test consists of placing a bulk volume of ore measuring 1250 ml, previously stage-crushed to −13.2 mm in the standard mill (305 mm diameter × 610 mm length) fitted with wavy liners, along with grinding media consisting of 2 steel rods with 45 mm of diameter

The Bond rod mill grindability test is a widely used tool to estimate the response of ores to rod milling. However, the mass of ore required to conduct the test, which can typically vary from about 8 to as much as 20 kg, may represent a challenge when sample availability is critical. The present work proposes an alternative procedure, which is based on the size-mass balance model with a specific account for the

Small-Scale Tests to Characterise Ore Grindibility

BOND ROD MILL GRINDABILITY The Bond rod mill grindability test is performed similarly to the ball mill test. The feed sample is stage-crushed to ½” (12.5mm) and the test is run under a 100% circulating load. The test can also be closed with various sieve sizes, but for AG/SAG mill analyses the standard 14-mesh (1.18mm) sieve is typically used.
