Extrusion layered crushing grinding type superfine smashing device

Abstract

The invention discloses an extrusion layered crushing grinding type superfine smashing device. The extrusion layered crushing grinding type superfine smashing device comprises a rack and a main shaft. The main shaft is located on the centerline of the rack. An extrusion layered crushing device is fixedly arranged on the rack and is fixed to the main shaft through a key I. A grinding device and a discharging device are sequentially arranged below the extrusion layered crushing device. The extrusion layered crushing device and the grinding device are both fixed on the main shaft and operate synchronously under the action of an external motor. The extrusion layered crushing device comprises an extrusion layered crushing barrel and a layered crushing disk, the layered crushing disk is installed on the main shaft through the key, and groove and ridge alternating structures are arranged on the surface of the layered crushing disk and the inner wall of the extrusion layered crushing barrel. The grinding device is composed of three levels of grinding mechanisms, and each grinding mechanism comprises a grinding disk and a grinding block. The extrusion layered crushing grinding type superfine smashing device can successfully smash a large number of materials greatly different in particle size at a time, the condition that materials treated with smashers need to pass through screens is improved, the smashing efficiency and smashing effect are improved, and the production efficiency of superfine powder can be improved.

Description

technical field [0001] The invention relates to an extrusion layer crushing grinding type ultrafine crushing device, which belongs to the technical field of powder crushing. Background technique [0002] The demand for powder has penetrated into various fields such as medical and chemical machinery, especially the production of ultrafine powder has become the key to determining industrial efficiency and the quality of people's livelihood, so higher requirements are put forward for powder crushing devices. There are many powder crushing devices, and the use of mechanical action to crush powder still occupies a large part. At present, the common mechanical crushing devices are divided into: extrusion crushing, impact crushing, friction crushing and splitting crushing according to the way of mechanical force. The single crushing method needs a long action time to meet the needs, which virtually reduces the work efficiency. Therefore, the combined powder crushing device has the...
