Hongxing Heavy Industry is a high-tech enterprise specializing in mining crushing equipment (crusher), construction sand (sand maker), industrial milling equipment (mill). Compared with similar products, products in this company are more innovative in terms of novel design, high grinding rate and energy consumption savings and they are the best fashion in metallurgical industry and and the best equipment among kinds of ore grinding equipment. Hongxing Heavy Industry is striving to create the most cost-effective supplier in mining equipment industry.The followings are some problems should be noticed in using sand amker: First, sand maker cannot be started and operated when it has materials, because it will burn out the motor for the high starting pressure and lead to other damages. So we must pay attention to the operation order. First start the crusher, and then join the raw materials. Second, any crusher has its own proper scope, it is the same as sand maker.

The raw material size can not exceed a certain size. Too much you pray will plug the feed head of sand maker, which less will cause the cleaning of sand Maker, more lead the broken of impeller and even cease production. Third, all the equipments need regular maintenance to, or it will be easy to damage mutual calculated wear of iron devices within the machine. It is necessary to check whether it needs to add lubricant after a period of time so that the sand maker can have a long service life. Fourth, for the sand maker is fixed with screws, it will be loose with regular strenuous exercise, if the sand maker makes abnormal sound, it is necessary to stop, find the reason, and tighten the screw timely. The solution to that problem is perfect sealing, keeping lubricating oil clean, improving working accuracy of thrust button installation. Originally, the levelness radial error of footwall installation is 0.8 – 1 mm. After improving, the error range is 1.3-1.5 mm.

When checking, we should guarantee the error of vertical degree between machine axis and hanging wall, middle game and footwall not more than the error range. Meanwhile, it can avoid middle game being out of shape and contact area reduction by using scraping and finish turning method. Thus it can guarantee over 80% of the contact area and uniform contacting area distribution. Put the spare middle game on platform to avoid its being out of shape. Adjusting tooth gear gap and the gasket in use should be processed carefully to guarantee the levelness of footwall.
