Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0016] The invention integrates the relationship between the two power systems of the crusher and the feeder, and fully avoids the occurrence of the phenomenon that the crusher is overloaded due to too fast feeding of the feeder, thereby damaging the structural parts of the crusher. In order to realize the effective synergy between feeding and crushing in the ore crushing process, so that the feeding is uniform, the crushing is rapid, and the production is continuous. The relay RJ3 is to protect the limit current value of the crusher motor M2, and an overcurrent relay RJ2 is added to control the highest current value generated by the crusher motor M2, thereby controlling the start and stop of the feeder motor M1.

[0017] The mineral crusher automatic feeding control device of the present invention, such as figure 1 , figure 2 As shown, it include...

Abstract

The invention relates to a self-feeding control device of a mineral crusher. A main circuit of a feeding machine motor M1 is connected with a thermorelay RJ1 and an AC contactor KM1; a main circuit of a crusher motor M2 is connected with a thermorelay RJ3 and an AC contactor KM2. The main circuit of the crusher motor M2 is additionally connected with an overcurrent relay RJ2, and the buttons of the feeding machine are connected with a normally-closed contact of the overcurrent relay RJ2, a normally-closed terminal of the thermorelay RJ1, and an AC contactor coil KM1 of the feeding machine motor. When the current of the crusher motor M2 exceeds the set value of the overcurrent relay RJ2, the normally-closed contact of the RJ2 is disconnected, the coil KM1 of the feeding machine motor loses power, the main contact of KM1 is disconnected, and the feeding machine stops operating. In the process of ore crushing, the signal of the crusher motor can be fed back to the feeding machine so as to control the operation of the feeding machine motor, thereby realizing the effective cooperation between feeding and crushing in the process of ore crushing to ensure uniform feeding, rapid crushing and consecutive production.

Description

technical field [0001] The invention relates to an automatic feeding control device for mineral crushers, which is suitable for various ore crushing industries and used in conjunction with mineral crushers and feeders. Background technique [0002] Crusher is a necessary equipment for the utilization of various hardness and larger ores. It is widely used in the crushing of iron ore, limestone, coal gangue, lump coal, gypsum and other medium-hard ores. Due to the need of energy saving and consumption reduction, heavy hammer impact crushers have been popularized in recent years. However, due to the large feed size and the continuous supply of the feed system (feeder), it is easy to block the main machine of the crusher, and even more Serious damage to the internal structural parts of the crusher host, causing the entire crushing system to be shut down for maintenance, wasting manpower and material resources. [0003] In the existing technology, such as figure 1 , figure 2 ...
