Vertical pulverizer

Abstract

The invention discloses a vertical pulverizer. The vertical pulverizer comprises a pulverizer body, and a powder outlet is formed at the upper portion of the pulverizer body. An inspection door is arranged in the middle of the pulverizer body, one side of the inspection door is rotationally connected with the pulverizer body through a fixing pin, and a fixing lock is arranged at the other side ofthe inspection door. A feeding hopper is arranged at the lower part of the pulverizer body and is communicated with the interior of a barrel body; and an air inlet pipe, a pulverizing cavity, a pulverizing device and a first motor are arranged at the bottom of the pulverizer body, the air inlet pipe is arranged around the bottom of the pulverizer body, an air blower is fixed to an opening of the air inlet pipe, the air inlet pipe communicates with the interior of the pulverizer body, and the pulverizing cavity is fixed to the bottom of an inner cavity of the pulverizer body. According to the pulverizer, a pulverizing plate is fixedly connected into the pulverizing cavity through a first spring, an air outlet is formed in the pulverizing plate, the first motor is fixed to the bottom of theouter side of the pulverizer body, the powder discharging efficiency can be effectively improved, and powder is prevented from being accumulated at the bottom of the pulverizer body.

Description

technical field [0001] The invention relates to a milling device, in particular to a vertical milling machine. Background technique [0002] The pulverizer is widely used in the grinding of mineral materials in metallurgy, building materials, chemical industry, mining and other fields. According to the fineness of the ground material and the fineness of the discharged material, the pulverizer can be divided into vertical pendulum pulverizer, There are six types of mills: high-pressure suspension roller mill, high-pressure micro-powder mill, straight-through centrifugal mill, overpressure trapezoidal mill, and three-ring medium-speed mill. Therefore, a mill for limestone processing The demand for powder equipment is increasing day by day. [0003] For the milling devices currently on the market, when the opening between the air inlet pipe and the main body of the mill is opened relatively low, it is easy to be blocked by debris, and it is difficult to clean and maintain.

Problems solved by technology

[0003] For the milling devices currently on the market, when the opening between the air inlet pipe and the main body of the mill is opened relatively low, it is easy to be blocked by debris, and it is difficult to clean and maintain. When the value is higher, the generated negative pressure has a weaker ability to adsorb the powder at the bottom, and some powder will accumulate at the bottom of the mill body
