Embodiment Construction

[0037] The inventors of the present invention have investigated the situation in which the same batch processing is repeated even when the same processing substance is used.

[0042] a) Adhesive process material adheres to specific locations of the comminution vessel and increases over time.

[0044] c) When the rotation directions of the stirring members are alternated, the adhering / increasing portion of the processed material can be removed. Then, by

[0047] FIG. 1 is a schematic configuration diagram showing a dry grinding system 10 as an example of the present invention.

[0052] Through this stirring, the shear force or impact force generated between the pulverizing media can miniaturize the processed material.

[0054] The cooling medium enters the jacket 25 from the inlet line 91 and exits the outlet line 92.

[0058] The drive unit 60 is a circuit for driving the motor 31 using the power from the primary side power supply 30, and can

[0060] The control unit 50 includes:...

Abstract

The present invention provides a dry pulverization system (10) capable of forming a sharp curve with less variation in particle size distribution after pulverization. It includes: a medium agitation type pulverizer (20), which is provided with a stirring member (23) that rotates simultaneously with the rotation shaft (22) inside the pulverization container (21); a drive unit (60), which drives the rotation shaft (22) Control part (50), it controls the rotation of described driving part (60), and control part (50) possesses: at least can input the setting function of alternate time; Function; an alternate output function indicating the direction of rotation towards the drive (60). The measurement function preferably measures the internal temperature of the pulverization container (21), and instructs the driving unit (60) to alternate from the rising state of the measured value.

Description

Dry crushing system technical field The present invention relates to a kind of dry pulverizing system using medium stirring pulverizer, particularly relate to a kind of implementation batch Dry crushing system for mass processing. Background technique [0002] The dry pulverization process using a medium stirring pulverizer is produced by using the agitated pulverizing medium. The shear force and impact force are used to implement the processing method of fine particles. [0003] Generally, spherical particles with a diameter of 3 to 15 mm, such as stainless steel or wear-resistant ceramics, are used as the processing medium. Most of the quality. Among the pulverizing processing methods are: continuous processing methods, which continuously add processed substances into the pulverizing vessel and continuously A batch processing method in which a predetermined processing material is put into the crushing container and then processed for a predetermined time. [0005] ...
