First, open shelves and unload the screw connecting upper shelf and middle box, next, use wrench to flip hex head part, and slowly open shelves. At the same time, we can hang the after-frame by cable suspension device, and then repeat the above process until shelves close.

1. Replacement of impact crusher plate hammer: plate hammer should be timely adjusted or replaced when they are worn to a certain extent to avoid the injury of the fasteners and other components.

2. Replacement of impact crusher liner: first, open the cover, remove the cotter pin, slotted nuts and bolts which are used to fix liner, and then replace the liner. If install a new liner, just to upside down the steps.

3. Treatment of impact crusher bearing: the reason why bearing is of over-high temperature are that: (1) excess or deficiency lubricating grease. Then we just try to check whether lubricating grease is excess; (2) smudgy lubricating grease. Then we just try to clean and replace grease;3damaged bearing. Then we just try to replace a new bearing.

Impact crusher plays a crucial role in sand making production line, we should timely maintain and repair it in the use of the process, try to eliminate problems in the bud to avoid more severe loss, in this way, ensure sand-making production line keeps in a normal and steady state.

Ways to the reduction of hammer crusher head wearing: select a reasonable speed. Quickly improve hammer heads impacting and hardening degree in early process; improve grate bar structure to make the material-excluding expedite; often adjust the gap between parts, so that it is in a proper range. These ways would help reduce hammer wearing. From analyzing factors that influence hammer crusher head, we should adopt different measures to reduce wearing, prolong the service life, reduce material consumption and downtime, reduce costs and improve the economic efficiency of enterprises.

At present, our country mainly adopts high manganese steel flat hammer and impact plate. Because different manufacturer adopt different heat treatment and material, the life expectancies are also equally intervallic. Our country also researched use dilute alloy white cast iron or of high chromium iron manufacture impact hammer for its high hardness, good wearing-resistance, convenient production, low cost, which achieved good results. There are a number of manufacturers adopt surfacing welding layer method by welding" - 64" or " - 64A" electrode or high fierce steel electrode it can not only improve the wear-resistance and service life, but also repair old plate hammer or impact plate. Plate hammer shape and fixing method are very important in repairing process, besides convenient dismounting, plate hammer shape also should improve the utilization rate of the metal. Plate hammer quality should be accurate for whose error should be limited within 0.5kg, in order to ensure the smooth running of the machine rotates. In addition, the rotor cannot rotate 1 / 10 of the circumference at any state in rotor static balance experiment.

With its high quality products such as China sand washer, Combination crusher, Portable crusher, Impact crusher, Hammer crusher, Henan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
