According to the experts in DSMAC, the artificial sand produced by the high-efficiency impact crusher reaches the superior index in the sturdiness and durability. In addition, this equipment is suitable for the fine or medium crushing of the hard and brittle materials like refractory material, cement, quartz sand, steel grit, slag powder, copper ore, iron ore, gold ore, concrete aggregate, and asphalt aggregate. In order to guarantee the good operation, it not only has to make daily maintenance and repair, but also to do no-load and load test fully. Today DSMAC introduces the test process of the tertiary impact crusher, and how to judge whether it is normal to all of you.
First the test time must be sufficient, for example, the no-load test of the impact crushing equipment should reach 2 hours continuously, and then check if the temperature of the bearing exceeds 30℃, if all fasteners are all firm and without relaxation, if all transmission parts functions stably, if all the high-speed rotating parts operates without scratch, flaking and grinding phenomenon and abnormal sound and if the discharging device can be regulated conveniently.
In the load test process, there should be no obvious impact sound or vibrating phenomenon. The largest feed particle size should comply with the regulations of crusher design. After continuous operation for 8 hours, the temperature rise of the bearing should not exceed 30℃, and the fractured sandstone material processing capacity and product size should comply with the design rules.
Impact crusher use impact energy to crush materials. When the impact crusher works, the motor drives the rotor of the impact crusher rotate with a high speed. When the materials get into the area which the hammers effect, under the impact function of the hammer at a high speed, materials are thrown to the impact device above the rotor continuously. And then the materials are rebounded from the impact liner to the area where the hammers effects...
