<p>A process for increasing solid content in ore pulp is disclosed, it is characterized in that an ore pulp concentration device is added behind the cyclone of the conventional technique. The process comprises the following steps: feeding the crude ore pulp with a solid content of 250-300g/l from the overflow port of cyclone in the conventional raw material grinding step into an added extra cyclone for concentrating, after which the solid content in the underflow amounting to 600-800g/l, conveying the underflow as a product to atmospheric pressure desilicification step, and returning the overflow after concentration into the intermediate pumping tank for circulation grading and condensing. The process can increase the solid content of ore pulp effectively, improve the technique index of desilicification procedure, and save the expense of the project. The process is used for the raw material grinding procedure.</p> |
