The causes of corrosion on the dedusting and defluorinating equipment under the blast furnace gas atmosphere in FCMP plant are discussed.

Specialized dehulling device for camellia oleosa seed was manufactured with a dehulling rate of 98.

The Paper puts forward that only optimizing the design of dewatering process flow,adopting advanced and appropriate dewatering equipment can the aims be achieved of improving the concentrate quality,reducing energy consumption and decreasing cost.

During the ninth Five-Year Plan period,a relatively rapid progress has been made in respect of research on coal dewatering equipment in China,but how to rationally select to use them remains to be a topic worthy of discussion.

The choice of dewatering equipments is very important to improve the efficiency of sludge dewatering.

Based on the structural characteristics of the existing domestic desliming equipment for iron ore, two kinds of compound force field desliming equipment with the same solvent and different structure, long column compound force field desliming equipment and cone compound force field desliming equipment, have been designed.

The design principle and structure characteristics of long-column-type and cone-type desliming equipment are introduces respectively.

The desliming equipment used in iron ore preseparation process is under the compound force field of gravity, medium resistance and magnetic force to carry out predesliming separation process in terms of objective mineral by means of the difference of feed ore in physical properties.
