Problems solved by technology

In the process of building a raw material mill building, the lime silo can only be built after the construction of the column of the plant is completed, and the column of the plant is generally required to be as high as 30 meters. Therefore, the corresponding cap foundation needs to be enlarged, and the construction period is long. Large investment, large investment in plant construction

Embodiment

[0015] image 3 It is a plan view of the raw material mill room layout obtained by the raw material mill room layout method according to an embodiment of the present invention. Such as image 3 As shown, the raw material mill building comprises four ball mills 1, four rod mills 2, four classifiers 3, two lime bins 4, four raw ore bins 5, four pulp tanks 6 and four grinding conveyor belts (in image 3 Not shown in ), corresponding to the formation of four raw material process lines. Because the amount of lime added is relatively small, one lime silo corresponds to two raw material process lines, that is, one lime silo adds lime to the bauxite in the two grinding conveyor belts at the same time through a conveyor belt or other means. In the method for arranging the raw material mill building according to an embodiment of the present invention, the lime bin 4 is arranged separately from the factory building column, that is, the lime bin 4 and the factory building column are sep...

Abstract

The invention relates to a method for laying out a workshop building and provides the method for laying out a raw material grinding mill plant layout. The workshop building comprises a lime bin, a classifier, a classifier platform, a feeding conveying belt and a plurality of workshop building upright columns, wherein the classifier is arranged on the classifier platform; and the lime bin and the plant upright columns are arranged separately so as to make the lime bin be independent of the workshop building upright columns. When the method for laying out the raw material grinding mill workshop building is used, a main body and the lime bin of the raw material grinding mill workshop building can be constructed synchronously, so the construction cycle is greatly shortened and the construction investment is greatly saved.

Description

technical field [0001] The invention relates to a plant layout method, in particular to a raw material mill plant layout method. Background technique [0002] In the alumina production process, the raw material process is roughly as follows: bauxite goes from the raw ore bin to the grinding conveyor belt, and lime is added in proportion to the bauxite in the grinding conveyor belt from the lime bin. The feeding conveyor belt transfers the prepared raw materials into the rod mill, and adds circulating mother liquor in the rod mill. The raw materials after being ground by the rod mill are pumped by the pulp to the classifier (hydrocyclone) for classification. The coarse particle pulp separated by the classifier is sent to the ball mill for secondary grinding; the fine particle pulp separated by the classifier is sent to the pulp tank. The pulp in the pulp tank is then pumped from the raw pulp to the desiliconization tank in the normal pressure desiliconization sub-process of...
