Abstract

The invention discloses a dry-process powder-making device adopting a roller press to grind powder, which comprises a feeding unit, a grinding and impurity removal unit, a dry powder homogenization storage unit, a granulation drying unit and a press feeding unit arranged in sequence along the production line Unit, the grinding and impurity removal unit includes a static powder separator connected to the feeding unit, the coarse material outlet of the static powder separator is connected to the roller press, the roller press is connected to the feed port of the static powder separator, and the static powder separator The fine material outlet of the machine is connected to the feed port of the dynamic powder separator, and the discharge port of the dynamic powder separator passes through the first bag dust collector, high square sieve (or double square sieve), and strong magnetic bar type iron remover in turn. 1. The screw conveyor communicates with the dry powder homogenization storage unit. The present invention adopts the dry powder milling device with the above-mentioned structure and adopts the roller press machine with the nail-casting roller surface designed for abrasive materials to grind the material, because of its higher grinding pressure, thereby improving the The high grinding efficiency and the high wear resistance of the casting nail roller surface also make the service life of the equipment longer.

Description

technical field [0001] The invention relates to a dry-process powder-making technology, in particular to a dry-process powder-making device and method using a roller press for grinding powder. Background technique [0002] Ceramic bricks are thin plate products made of clay and other inorganic non-metallic materials used to cover walls or floors. Ceramic bricks are generally formed by dry pressing or extrusion. Extrusion generally adopts wet powder making process, while dry The milling process of pressed powder is divided into dry milling process and wet milling process. [0003] Among them, the raw material milling equipment of the wet milling process adopts the intermittent or continuous wet ball milling method. After grinding, the water content of the slurry reaches about 35%, and the ground slurry is dried and granulated by a spray drying tower. After granulation, the water content of the pellets is 5% to 7%, and then the pellets enter the aging warehouse for 24 to 36 h...
