Description

Technical Field

[0001] The utility model relates to the technical field of production and processing of chemical intermediates, in particular to a grinding machine used for chemical intermediates. Background Art

[0002] Chemical intermediates are intermediates produced by using coal tar or petroleum products as chemical raw materials to manufacture dyes, pesticides, medicines, resins, additives, plasticizers, etc. Most organic chemical reactions are completed by generating certain intermediates. These intermediates are very active and exist for a short time. After they are formed, they immediately participate in the following reaction, so they are usually called active intermediates. Although active intermediates are very active, they still have a certain relative stability and can be detected. Some can even be separated under appropriate conditions. In the process of processing and producing chemical intermediates, a grinding process is required to carry out the next step of production and processing. A grinder for chemical intermediates has come into being. Most of the existing grinders for chemical intermediates are that personnel add the chemical intermediates to be ground into the grinding box, and then drive the grinding roller to move through the motor, so that the grinding roller contacts the chemical intermediate or the bottom wall of the grinding box to rotate and then squeeze and grind the chemical intermediate. After the grinding is completed, the personnel need to use a brush to clean the chemical intermediates adhering to the grinding roller, which increases the labor participation of the personnel, and some chemical intermediates are not pre-crushed before grinding, which leads to low grinding efficiency and inadequate grinding.
