Abstract
The invention provides an artificial marble and a method for manufacturing the artificial marble. The artificial marble is manufactured using raw materials such as silica, fluorspar and one or more waste materials. The one or more waste materials are selected from a group that includes limestone, clay, magnesite and phosphate.
Claims8
A method for manufacturing an artificial marble, the method comprising:
- grinding a set of raw materials to a fine powder in a ball mill with a speed of about 400 revolutions per minute to about 500 revolutions per minute for a period of about 2 hours to about 3 hours, wherein the set of raw materials comprises silica and at least two raw materials from a group comprising limestone, clay, magnesite, phosphate and fluorspar;
- sieving the fine powder for filtering out particles having diameter more than about 100 microns;
- mixing the fine powder to obtain a homogenous mixture;
- shaping the homogenous mixture;
- drying the homogenous mixture in response to shaping;
- and
- firing the homogenous mixture at a temperature of about 750° C. to about 1350° C.
