Preparation and grinding of clay via dry processing<\/h2>\n

[\/vc_column_text][vc_empty_space][vc_column_text]Since it is done using impact or percussion, the dry milling and grinding of clay will always be more effective with dry, hard clays than with wet, soft clays, which absorb part of the energy of the impact due to plasticity, thereby reducing the effectiveness of the process, making it unfeasible.<\/p>\n

 <\/p>\n

Therefore, it is advisable to use dry processing:<\/p>\n

\u00b7 For clays with a moisture content under 12% which may vary according to plasticity.<\/p>\n

\u00b7 For clays with high limestone content, in order to minimise the presence of “lime blows” in the finished pieces.<\/p>\n

\u00b7 When you want to produce a quality ceramic product, such as floor tile, stoneware, roof tile, face brick, etc.[\/vc_column_text][vc_empty_space][\/vc_column_inner][\/vc_row_inner][vc_empty_space height=”50px”][vc_row_inner row_type=”row” type=”full_width” text_align=”left” css_animation=””][vc_column_inner width=”1\/2″][vc_column_text]<\/p>\n

Preparation and grinding of clay via wet processing<\/h2>\n

[\/vc_column_text][vc_empty_space][vc_column_text]We understand wet processing as the process capable of working with clays above 12% humidity. The main debate lies in the selection of equipment that can be used for secondary grinding, after a primary phase of crushing. In this case, the ceramicist should choose between the Pan Grinder and the Crusher, based on the cost and space available, the moisture content and abrasion rate of their clays.<\/p>\n

 <\/p>\n

After this secondary grinding phase, a rolling mill is used to achieve more finely granulated clay. With a second and occasionally third laminate, suitable crushing qualities are achieved to produce ceramic products with added value, such as stoneware, roof tiles or facing brick.[\/vc_column_text][vc_empty_space][\/vc_column_inner][vc_column_inner width=”1\/2″]

Direct setting<\/h2>\n

[\/vc_column_text][vc_empty_space][vc_column_text]The principle of direct setting consists of drying the wet (or green) bricks in the same kiln cars and is designed for clays with low drying shrinkage and high mechanical resistance, requiring extrusion with low humidity and high pressure. The dryers used in this process use the kiln cars to transport the “raw” bricks to the drying facility, allowing for fewer loading and unloading devices.<\/p>\n

 <\/p>\n

In addition, they allow for increased simultaneous production capacity, based on the acceleration of the production rate of the furnace, with a low investment in mechanisms, a reduction in the general maintenance of the plant and a better optimisation of the production process.[\/vc_column_text][vc_empty_space][\/vc_column_inner][\/vc_row_inner][vc_empty_space height=”50px”][\/vc_column][\/vc_row][vc_row css_animation=”” row_type=”row” use_row_as_full_screen_section=”no” type=”grid” angled_section=”no” text_align=”left” background_image_as_pattern=”without_pattern” z_index=””][vc_column offset=”vc_hidden-lg vc_hidden-md”][vc_empty_space height=”50px”][vc_column_text]<\/p>\n
