Three maintenance methods of jaw crusher

There are roughly three types of planned overhauls for jaw crushers: minor, intermediate and overhaul.
 
Minor and intermediate repairs are the main repair methods. Through minor and intermediate repairs, maintain the equipment to make it work well during the two overhauls, and determine the work content of the overhaul. The two repair intervals proposed below are calculated on a three-shift daily basis.
 
 1.The main contents of minor repairs: check and repair the adjustment device, adjust the clearance of the ore discharge; replace the worn liners and thrust plates; repair and replace the transmission parts; clean individual parts of the crusher; Adjust the lubrication system, etc. The interval between minor repairs depends on the operation of the equipment, and it is generally from half a month to once a month.
 
2.The main content of the intermediate repair: including the entire work content of the minor repair. In addition, replace worn thrust plates, bushings, tie rods, liners; check, turn, grind and cast eccentric shaft bushings, connecting rod head bushings, and movable jaw bushings. The interval between two intermediate repairs depends on the wear of the spindle bush, the connecting rod head bush and the movable jaw bush, and it is generally once a year.

Method of calculating cement ball mill capacity

Cement ball mill  is commonly used crushing equipment in the industry ,the statistics on the output of the ball mill in actual production is an important basis for the report-type statistics of the production workshop. The data is mainly the statistics of the production of different shifts and the output of the ball mill, and we usually calculate the capacity of the mill. The basic methods are: the measuring method, the feeding weight measurement method, and the estimation of the output per ton of grinding body. Below, Dawning introduces you to the calculation of the specific yield of different methods. 1. Volume method The bin method is one of the easiest methods for calculating the actual output of the ball mill. For the actual measurement, we take a simple weight measurement as an example, weigh a small iron drum of 1000 ml of water, and then we will Put the cement or raw material into it, tap it, smooth it, weigh it, then pour it out, fill it with water and weigh it again, then...
