Jaw crusher starting step machine instructions and non-standard cause 

crusher

<P> first, this paper is mainly on the jaw crusher preparing for operation are explained, and then introduces the jaw crusher when starting up the machine needs. In the machine before starting the main components, connections to check the equipment and the fastening bolt, whether the loosening phenomenon, safety device has not been retained its integrity, and then check the crushing cavity, after all this done, ensure the pe jaw crusher operation preparation. </P>
<P> start normal operation steps of jaw crusher is consistent with other machine. Because must follow the rules in order to start, start in the main motor, to ensure the uniformity of feeding, the bearing temperature machine should be maintained in a certain degree, should not be too high. In the electric appliance equipment jaw crusher’s automatic tripping of the case, and do not know what reason, not the machine forced continuous start. </P>
<P> then stop the steps of pe jaw crusher, due to stop working at a machine, we need more than once to remove the crushing cavity ore, of course, this is to be in power off condition. Then, we must pay attention to order and machine broken jaw stop start sequence Is it right? In the opposite direction, if the machine is the production process of the direction of operation, then it is correct. </P>
<P> The components of ultra difference causes uneven components: intermediate alloy. Calculation of charge or batching error. Oxidation burning loss is too large. Melting mixing non-uniform.</P>
<P> pore forming reason: in alloy solidification with holes exist in the form of castings. Subcutaneous blowhole formed by the reaction of metal and the mold in the casting under the epidermis. Clip attached slag or oxidation gas skin were mixed with liquid alloy after the formation of pores. </P>
