The utility model discloses an organic pigment grinder, which comprises a feeding hopper, a pre grinding drum and a grinding drum connected in turn; a rotating shaft is suspended at the middle shaft of the pre grinding drum, the outer wall of the rotating shaft is wound with a spiral blade, and several groups of evenly distributed blades are fixedly installed at the end, and the end mouth of the feeding hopper is close to the position of the rotating shaft; the bottom center of the grinding drum is provided with a base, a top fixed installation fixed plate, and a bottom The base is equipped with a rotary table which is opposite to the fixed plate. There is a gap between the fixed plate and the rotary table. The diameter of the fixed plate and the rotary table is smaller than the inner diameter of the crushing cylinder. The fixed plate is equipped with a central channel which is connected with the outlet of the pre grinding cylinder. Several groups of evenly distributed rollers are installed on the inner wall of the crushing cylinder. The utility model is provided with a pre grinding cylinder before grinding, which adopts the interaction of three components, i.e. a fixed disc, a rotary table and a grinding roller, to crush the original organic pigment particles and then carry out high-strength grinding, thereby damaging the aggregation force of the pigment particles, making it easier to grind, with higher efficiency, and making its fineness meet the requirements.

一种有机颜料研磨机
本技术属于有机颜料生产
,具体涉及一种有机颜料研磨机。
技术介绍
为充分发挥有机颜料的着色力、鲜艳度、光泽度等使用性能,有机颜料粒子呈微细、均匀、稳定的状态分散于基料中,所以有机颜料在生产加工过程中尽量使得颜料粒子微细化,目前大多采用物理研磨设备进行分散加工。目前在研磨过程中容易出现研磨颜料达不到细度要求的情况,主要原因有两方面:颜料的原始颗粒粒径过大,直接进行研磨容易造成颗粒不均匀,无法达到要求的细度所致;颜料颗粒自身聚集紧密很难分散。所以需要一种研磨效率高的研磨机。
技术实现思路
针对现有技术中的不足与难题,本技术旨在提供一种有机颜料研磨机。本技术通过以下技术方案予以实现:一种有机颜料研磨机,包括依次连通相接的进料斗、预磨筒和碾碎筒,进料斗与预磨筒顶部连通,预磨筒末端与碾碎筒顶部中心连通;预磨筒中轴处悬挂转轴,转轴的外壁缠绕螺旋叶片、末端固定安装若干组均匀分布的刀片,进料斗的末端口靠近转轴位置;碾碎筒内底部中心设有底座、顶端固定安装定盘,底座上安装有与定盘相对立设置的转盘,定盘与转盘之间设有间隙,定盘与转盘的直径均小于碾碎筒内径,定盘设有与预磨筒出口连通的中心通道,碾碎筒的内壁上安装若干组均匀分布的碾辊。进一步地,预磨筒内壁上设有若干组凸棱。进一步地,碾碎筒内还设有过滤振动筛,过滤振动筛设置在碾辊和转盘下方,过滤振动筛的外侧与碾碎筒内壁相连、内侧与底座相连,碾碎筒内底部设有与其连通的排料通道,排料通道设置在过滤振动筛下方位置。进一步 ...
