Production process of magnesium chloride granules

Abstract

The invention discloses a production process of magnesium chloride granules. The production process comprises the following steps of: crushing crystallized magnesium chloride, then, placing the crushed magnesium chloride into a dissolving tank, stirring the crushed magnesium chloride, then, standing for settlement, inspecting the baume degree of the liquid not to be lower than 33.5Be', and primarily filtering the liquid in the dissolving tank to obtain primary filtrate magnesium chloride; naturally settling the primary filtrate magnesium chloride for at least three days, then, sequentially placing the primary filtrate magnesium chloride into a two-effect separator and a one-effect separator to carry out steam-liquid separation to obtain liquid magnesium chloride; and delivering the liquid magnesium chloride to a dust-free pelleting chamber through a pipeline to pellet to obtain finished products of the magnesium chloride granules. The method is advanced in process design, strong in operability, controllable in process parameter and capable of realizing large-scale industrial production; the prepared product is high in purity and capable of meeting the requirement of a high-quality product; the magnesium chloride granules are high in dissolving speed and clear, transparent and free of impurities after being dissolved; and an automatic production line is adopted, and the product is high in stacking density and not easy to air slake.

Description

technical field

[0001] The invention relates to a production process of magnesium chloride particles. Background technique

[0002] The magnesium chloride produced by the magnesium chloride production process in the prior art is mostly magnesium chloride flakes. This kind of magnesium chloride flakes has low content, many impurities, and a slow dissolution rate, which affects the use efficiency and causes prolonged working hours. After dissolving, there are impurities, which need to be precipitated and filtered. And most of them adopt full manual production, manual weighing and packaging, and the production efficiency is low. The product has edges and corners, and the package is prone to breakage during transportation. The product has a large area and cannot be evenly mixed with other products. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a production process of magnesium chloride granules with reasonable de...
