Simple method of cooling clinker crusher bearing seat

Simple method of clinker crusher bearing cooling - 2020 12 - 03 a company after the 5000 t/d clinker production line put into production, the average in 5500 ~ 5800 tons, as the production of Taiwan continues to increase, lead to rising temperature of the clinker, makes out the clinker cooler temperature at 100 ~ 120 ℃, the temperature will be higher in the summer, the bearing temperature rises to above 70 ℃ will call the police, 80 ℃ jump stop, in order to reduce the crusher bearing temperature, the bearing seat with two fan to blow cold to cool down, sometimes still makes production is affected. A, the causes of high bearing temperature ( 1) The increase of the kiln production, lowered the cooling effect of cooling machine, grate cooler discharging temperature is high, the crusher rotor temperature rise, and through the shaft to the bearing, bearing temperature rise; ( 2) Clinker crusher grease quantity more than half of the bearing cavity volume, due to the excess grease, bearing heating temperature rise; ( 3) Broken clinker in the process of producing a large amount of dust, as part of the fine dust into the bearing seat, make the oil metamorphism in bearing seat, and heat generation. Second, the bearing cooling way of improvement ( 1) In clinker crusher respectively under the two bearing oil cavity at the bottom of the horizontal direction drill a 20 mm diameter hole, tapping on both ends, after wearing in circulating cooling water pipe, to cool bearing oil cavity, to reduce the effect of bearing temperature, at the same time access transparent glass tube in the outlet pipe, is advantageous for the observation of the circulating water flow and water quality status; Specific methods as shown in figure 1 a, one of the shaft diameter of 250 mm, the diameter of the end cover of 450 mm, and the length of the bearing is 490 mm, the distance of the lower part of the pitch of cooling water pipe of 40 mm. On both sides of the pitch of cooling water pipe on the edge of the distance for each 75 mm, upper part of the cooling water pipe hole is apart from the distance is 290 mm, 500 mm high bearing, high seed 50 mm, bold lines for the position of the cooling water pipe, As shown in figure 1 b) Sketch map is shown in figure 1: the cooling water pipe, 2) In the crusher bearing upper with compressed air blowing on the upper part of the bearing and shaft surface, cooling effect, and can reduce dust to enter, and compressed air used manual valve control, can be adjusted according to the site condition to stop and open the valve opening: ( 3) To change the original add 2 # of extreme pressure lithium base grease for mobil lithium base grease, do it less frequently, during oil filling to prevent the excessive grease to join. After the improvement, now in more than 5800 t/d clinker production, bearing temperature of clinker crusher about 33 ~ 38 ℃, have had a good run. （ Source: shandong ShenFeng group wefound cement company)
