After hearing the start-up warning signal bell, the operator shall keep a half arm distance from the control cabinet, gently press the "start" button with his fingers and start the crusher(aluminum oxide abrasive media). After hearing the start-up warning signal bell, the operator keeps a half arm distance from the control cabinet, and lightly presses the "start" button with his finger to start the linear screen(alumina abrasive). The screw shaft should be started with no load. 

The wear of the tool flank increases, the friction between the flank and the machined surface intensifies, and the plastic deformation increases, resulting in the enhancement of cold hardness(black silicon carbide). It is strictly forbidden to start with load. The particle size of brown corundum determines the price and performance(alumina abrasive). If it is too tight or too loose, or the wear is severe, the belt should be adjusted or replaced.

According to the lubrication standard table, refuel all parts of the equipment, and there must be no shortage of oil, and record it in the equipment refueling record book(aluminum oxide 80 90 grit). Check the abrasion of the guard plates on both sides, if they are severely worn, they should be replaced. Check the tightness and wear of the V-belt (or flat belt)(aluminum oxide suppliers usa). Chromium oxide, iron oxide, magnesium oxide, oxidation bowl, etc(alumina abrasive).

Before starting up, check whether there are potential safety hazards in the workplace, carry out daily spot inspection on the equipment, and start up after confirming that there is no abnormality(alumina abrasive). When the crusher is running, the operator must stand within the injection safety angle and pay attention to whether the old tiger mouth of ore feeding is blocked(aluminum oxide abrasive blasting grit). If any abnormality is found, report and deal with it immediately.

The chromium corundum block cooled and solidified after melting has a small porosity, so the key parts of the furnace body are built with chromium corundum, and the brick gaps are filled with chromium corundum powder and a binder(aluminium oxide sand). Noise injury control measures wear earplugs as required. Dust injury control measures wear masks as required(alumina abrasive). In case of any abnormality, report it to the police in time(refractory materials).

Control measures: shut down for maintenance and cut off the working power supply in time(alumina abrasive). For mixing drums with machinery and corresponding pipelines, truck climbing and discharging shall be arranged according to the length of power failure and manpower distribution(garnet sand). Brown corundum is added into the refractory in proportion, which can make the general refractory become high-grade refractory. 

When operating with the maintenance personnel, the maintenance personnel shall make safety notification before operation, eliminate the occurrence of "three violations", bear in mind the deep danger of the post, and carry out the operation when safety is confirmed(alumina abrasive). The post personnel shall operate in strict accordance with the relevant requirements of the safety operation instruction and post responsibilities(46 grit aluminum oxide).

The crushing process, like the selection of raw materials, is the key to the preparation of high-quality products, which has a direct impact on the properties of products(alumina abrasive). During the operation of the equipment, pay attention to check the temperature and sound of the motor, whether the material inlet and outlet hopper is unblocked, and whether the spring tensioning device of the transmission belt is intact(240 grit aluminum oxide blast media).

Silicon carbide is a super hard metal material, which is currently used in automobile clutches and carbon-ceramic brakes(steel grid). Check whether the nuts of the dynamic frequency and fixed jaw are loose and have abnormal noise(alumina abrasive). Start up and hand over the shift, do a good job in the sanitation of site equipment, carefully fill in the shift handover record, and hand over the shift with the successor at the post(aluminum oxide grit blasting). 

If it is necessary to install the rotor hammer, impact lining plate and box lining plate before starting, check whether there are cracks, cracks and other defects, and whether the lining plate screws are fastened. Before startup, open the inspection door to check whether there is material accumulation in the crushing bin to ensure its no-load startup(aluminum oxide blasting grit). If so, shut down the machine first and then fasten it with a sleeve(alumina abrasive).

During the operation of the equipment, the bearing temperature shall be checked frequently and tested with the back of hand(glass bead blasting media suppliers). It shall not be higher than 75 ℃, which is abnormal and must be shut down for oil injection(alumina abrasive). After hearing the start-up warning signal bell, the operator checks the equipment to ensure that it is normal, and then press the "allow start" button to return the start-up signal to the main control(aluminum oxide blast media canada).

After starting, the screw shaft can run smoothly before feeding(alumina abrasive). The feeding should be stopped before the machine is shut down, and the machine should be shut down after the materials in the tank are drained. After the impact crusher is started, observe whether the current is stable under no-load and whether the machine body vibrates(white aluminum oxide 80 grit). Check whether there are foreign objects or bulk materials in the tank. 

If there are foreign objects or bulk materials in the tank, they should be picked up before starting(alumina abrasive). Before handling equipment failures, notify the shift leader, after getting the permission of the main controller, disconnect the on-site power supply, and hang up the "equipment maintenance, no closing" warning sign, then equipment failures can be handled(alumina grit). Check the gap between the screen box and the fixed object.
