How To Ensure Continuous Work Time Of The Crusher

Impact crusher (Impact breaker) is a new type of high-efficiency crushing equipment

. Its features are small in size, simple in structure, big reduction ratio, low energy, large production capacity, equal product granularity, selective in crushing minerals. It is promising equipment.

It involves the use of impact rather than pressure to crush material. The material is contained within a cage, with openings on the bottom, end, or side of the desired size to allow pulverized material to escape. This type of crusher is usually used with soft and non-abrasive material such as coal, seeds, limestone, gypsum or soft metallic ores. There are two types of impact crushers: horizontal shaft impactor and vertical shaft impactor.

Electric drive production machinery is appears as a motor load. Usually mechanical load torque production characteristics are for short of load torque characteristics, or load characteristic.

As for impact crusher, the load torque falls into resistance torque and cogging torque. When the sensor is installed on detected objects or entering the medium to be measured, it will absorb energy or interference from the object and the medium. The physical quantity to be measured is deviation from true value, thus making it impossible to achieve the desired measurements, this is known as load characteristic of testing device (load effect).

Instantaneous load characteristics are generally indicated by a transient load curves. Although the accuracy of that method is poor, it is simple and intuitive, practical and user-friendly. Instantaneous load curve represents that when a focus occurs in a rectifier case, it is corresponding to a certain voltage (peak), which allows a maximum tube current (relationship between the average exposure time curve, different mining equipment has different curves.

The continuous load characteristics of mining equipment are generally represented with heating and cooling curves. Each mining machine has a rated maximum thermal capacity. In accordance with this value, we determine the continuous operation time of mining equipment. Corresponds to a certain amount of heat generation rate, the relationship curve of anode heat accumulation and time is called the heating curve of mining equipment. Both curves of the maximum thermal capacity of mining equipment are drew in the same diagram, which reflects the continuous load characteristics of cone crushers used mining equipment.

Impact Crusher Operating principle:

Impact crusher is one type of high-efficiency crushing equipment. When the ore where on the screen leave was crushed by the high-speed rotary rotor's hard-alloy hammer, then though the basic crushing stone follow on the tangent fly the first impact plate with the higher-speed for the crushing again, the impact plate will be stricken back by the ore. And other ore behind of rotor blows out collision. Ore after firstly crushing room break up the some size , though impact plate and the rotor space to discharge the secondary crushing room , going on be struck repeatedly, when the size of the stone is general then output from the output port of the bottom of the crusher .
