Abstract

A breaking mixer with vertical hammer plate for the mixture of fused chemical and solid powder is composed of a casing with feeding pipe and discharge pipe, a motor, and a breaking chamber with a mainshaft driven by motor, a hammer plate holder fixed to lower end of mainshaft and with at least two radial slots and the hammer plates (2-8 hammer plates in each slot). When the mainshaft is rotating at high speed, said hammer plates can play their breaking role.

Description

technical field [0001] The invention belongs to the technical field of chemical equipment, and relates to a crushing and mixing device for melt slurry containing suspended solids, in particular to a vertical hammer crushing and mixing device. Background technique [0002] In the chemical fertilizer melt granulation process, the material containing nitrogen element (urea or ammonium nitrate) is first melted, and then mixed with the powder material containing phosphorus element and the powder material containing potassium element heated to the process temperature The device stirs and mixes into a flowable liquid composite slurry with a certain temperature, and then the mixed slurry enters the cooling medium in the form of droplets through a special granulation nozzle. The refrigerant can be gas or mixed with materials. Immiscible liquid, the liquid droplets automatically shrink into spherical solid particles during the process of contacting and cooling with the refrigerant. ...
