A sieving mill with large crushing ratio supported by idler roller includes a cylinder with hollow holes on it, an end liner plate is installed at the end of the cylinder body, a cylinder liner plate and a lifting liner plate with several intervals are installed on the side wall of the cylinder body, and the outer cover of the cylinder body is provided with a shell. The feeding hollow shaft, the cylinder body, the shell and the discharging hollow shaft cooperate with each other to form a rotating part. The rotating support is on the supporting wheel set, and the screw structure is arranged in the feeding hollow shaft to guide the material into the inner cavity of the cylinder, and the screw structure is arranged in the discharging hollow shaft to export the material into the inner cavity of the cylinder. During the rotation of the rotating part, the material is lifted and projected on the inner wall of the cylinder under the action of the lifting liner so as to achieve crushing. This application integrates the functions of secondary crushing, screening and impurity removal. It can simplify the traditional crushing and grinding process into a sieving grinder with roller support - conveying - finished product bin + dust collecting system. Simplify process flow, reduce investment in equipment and infrastructure, and reduce operation and equipment maintenance costs.

一种大破碎比托轮托辊支撑的筛分式粉磨机
本专利技术涉及一种破碎装置,尤其是涉及一种大破碎比托轮托辊支撑的筛分式粉磨机。
技术介绍
传统的破碎磨粉系统由初次破碎,二次破碎,粉磨机,筛分机,输送设备,收尘设备等构成,整个工艺设备多,环境扬尘大,操作与维护困难,工艺流程过长造成基建投入很大。目前的破碎磨粉生产工艺:氧化铝结壳块采用颚式破碎机将来料破碎至小于200mm以满足后续筛分式粉磨机的入料要求,通过皮带输送机输送至缓冲仓,再由振动给料机输送至筛分式粉磨机、(或自磨机,反击破)破碎粉磨后的物料再由平皮带输送至斗式提升机,斗式提升机输送给筛分机,筛分机筛网下合格的物料由溜槽或皮带输送至成品仓,筛分机筛网上不合格的物料再由皮带返回再次破碎,整个系统中存在以下问题;1.由于现有筛分磨机的入料是通过磨机轴承的空心轴给入筛分式粉磨机,受筛分式粉磨机轴承直径的限制入料粒度小于200mm,如果为提高入料粒度而加大空心轴直径,会极大增加筛分式粉磨机的加工难度和制造成本。2.颚式破碎机难以有效密封,收尘效果差,易堵塞,清料维护困难;3.设备多、占地空间大,造成设备及基建投资较大。4.工 ...
