Embodiment Construction

[0033] Chemically gypsum Y is a salt dissolved in seawater. When seawater evaporates, the salt is expelled and deposited in the remaining water. Initially, less soluble carbonates (not shown in this figure as deposits) are expelled and evaporate further with gypsum Y. During geologic time, sediments were deposited on top of gypsum, and the pressure of this sediment (i.e. claystone), converted gypsum Y to anhydrite A by "squeezing" water. figure 1 is an illustration of a natural deposit 1 of the rock mineral gypsum Y / anhydrite A. The lower layer of anhydrite 12 is covered by an overlying layer of gypsum 11 , both of which vary greatly in thickness. The gypsum layer 11 and the anhydrite layer 12 mix at the interface in a typical migmatite, ie at the anhydrite crystals 111 which are uniform "lens" anhydrite A deposits surrounded by gypsum Y.

[0034] The mineral gypsum and anhydrite fractions of the rock material mined at the gypsum-anhydrite interface are unknown. The limita...

Abstract

Apparatus (2) for blending loose rock material (221) of a changing mineral composition having different mineral components (222, 223) to provide blended rock material (224) having predetermined portions of the different mineral components. A conveyor (21) for transporting the loose rock material (221), a first container (20) for depositing the rock material (221) of a changing mineral composition onto the conveyor (21), a second container (23) and a third container (24), both capable of separately depositing rock material of the different individual rock material components onto the conveyed rock material (221). An acoustic mineral detector unit (25), arranged after the first container (20) and before the second and third container (23, 24) for detecting the portions of the different mineral components in the conveyed rock material and regulating the quantity of the different individual rock material separately deposited from the second or the third container based on the detected portions.

Description

technical field [0001] The present invention relates to an apparatus for mixing loose rock material and a method for mixing loose rock material to provide mixed rock material having predetermined fractions of different mineral compositions. Background technique [0002] The "rock material" mentioned in the present invention takes loose sulfate rock material with different mineral composition and variable composition as an example. Certainly this loose rock also can be another kind of material. Sulphate rocks are found natural mineral rocks calcium sulfate dihydrate (CaSO4 2H2O), commonly known as gypsum, stucco or plaster, and anhydrous anhydrite (CaSO4) in various hydrate stages. The raw gypsum ore is crushed and usually stored near the factory for further processing, i.e. for the manufacture of gypsum wallboard. [0003] Gypsum and anhydrite rock materials are sedimentary rocks deposited in thick beds or layers and mined in quarries and underground mines. Both minerals,...
