Grinding Methods for Clay Operation

Grinding Methods for Clay Operation

Zhengzhou, China (prHWY.com) June 4, 2012 - Clay crusher, clay grinding mill, flotation machine, magnetic separator is widely used in clay processing plant for clay powder making process. In the ultrafine ball mill, the clay is griound combined together with wet or dry method. After iron removal is fifnished by magnetic separation, it can be directly applied in the preparing processes, like ceramics production, cement preparation, paper manufacturing industry, stuffing preparation, etc. Clay grinding machines including Hammermills, hammer crushers, and Disintegrators to grind clay and other materials.

The primary clay belongs to mixed stones with uneven volume, containing stone dust, sand grains, and blocks. In order to fully apply stones to porcelain, fire-resistant materials and stuffing, we must grind fine-sized clay minerals into powder or pulpy industry materials. As for the grinding process, ball mill is the best choice, because it grinds clay minerals by dry or wet method.

The clay raw materials produced through dry grinding technology are mainly applied to the production of cement preparing, raw materials of muffle painting, paper manufacturing industry, and porcelain granule. In the process of dry grinding, ores in mill cavity are crushed under abrasion force, impulse force, and extrusion force.

The clay raw materials made through wet grinding method are mainly applied to production process of porcelain and fire-resistant materials. By wet grinding of clay, materials are processed in watery environment. When stones enter into ball mill, they are crushed under strong impulse effect.

Certain content of iron exists in clay raw materials which are produced by mill; it will influence the quality of later produced products unless the iron is removed. Flotation separation is mainly adopted to remove the iron in clay. The fine particles of required size enter the cyclone collector through pipe, while the large particles drop back to the grinding unit for regrinding. The final powder is discharged at the discharging valve.vibrating screen:http://www.hxjq-crusher.com/40.html

Flotation can be divided into three kinds: The first one is fluorine-acid method. This method is widely used for good flotation effect, easy control, and steady index. However, abration of fluorinion to earth and its damage to ecological environment are serious. The second one is no fluorine-acid method. The biggest advantages are avoiding using fluorinion which has damage to environment and steady production index. But the abration of strong acid to dressing plants cannot be ignored. This method has rather high requirements for dressing plants. The third one is the method without fluorine and acid. Under natural pH condition, through the reasonable allocation of zwitterions collector, a special high concentration environment of ore slurry flotation is created, which can preferentially floating impurity minerals. However, to this day, this method is not widely used for strict demands for raw sand processing and ore slurry environment, also it is not easy to control in production.

Hongxing Machinery has more than 30 years' experience in developing and constructing mineral processing equipments such as ore crushers, mineral grinding mills for quarrying and mining. We are ready to provide you with a range of grinding mills suitable for clay grinding. They can process clay materials of 300-400 in size, and their production capacities can reach more than 100 t/h. The final products are of different sizes to meet customers' different requirements.
