Description

Technical Field

[0001] The utility model relates to the field of pendulum type grinding mills, in particular to an internal reduction pendulum type grinding mill. Background Art

[0002] Internal reduction pendulum mill, also known as suspension roller mill or Raymond mill, is a kind of powder making equipment which combines "ring-roller" grinding with airflow screening and pneumatic conveying. Its working principle is as follows:

[0003] The block material is crushed into a certain size by the jaw crusher (powder or fine-grained material can be crushed without the jaw crusher), and the bucket elevator vertically transports the material to the storage hopper, and then the electromagnetic vibrating feeder quantitatively, evenly and continuously feeds the material into the main machine for grinding; the ground fine powder is brought out by the airflow of the blower, and is classified by the analyzer placed above the main machine. The fine powder that meets the requirements of fineness enters the large cyclone separator with the airflow. The powder after separation is discharged through the discharge pipe as a qualified product; the airflow is discharged from the upper end of the large cyclone separator. The return air duct enters the blower inlet, and the entire air flow and air delivery system is a closed cycle and operates under negative pressure. Since the ground material contains moisture, it evaporates and turns into gas during grinding, and the gas leaks into the air duct at the flange joints of the entire air duct, resulting in an increase in the air volume in the circulating air flow. This increased air volume is introduced into the small cyclone separator from the residual air duct between the blower and the main machine. The fine powder brought out by the air flow is collected by the small cyclone separator and discharged from another discharge pipe. The gas is discharged into the atmosphere through the exhaust pipe at the upper end of the small cyclone separator.

[0004] Taking the internal reduction swing mill model 4R3216 as an example, in actual use, the operator cannot directly observe the grinding conditions of the internal materials when the equipment is running, such as the flow state of the material, the degree of grinding, etc., so as to promptly discover possible problems, such as material blockage, uneven grinding, etc., and take corresponding measures to make adjustments, thereby reducing the continuity and stability of the machine during production.
