The original machine adopts double slats, because the middle half slats directly bear the impact of the rotor and limestone , resulting in greater wear, while the slats on both sides wear less. After the middle half of the screen frame is excessively worn (see Figure 1), the screen is not installed firmly, and often loose and fall off, resulting in a large amount of maintenance work. More importantly, the intermediate frame corresponding to the screen bars of about 14% of the area of the blocked material, after passing crushed limestone can not normally discharge Here, part of the cycle is repeated crushing limestone in the crusher, crushing resulting in low efficiency, The output at the time of Taiwan is not high. 2. Improvement measures Remove the middle half of the sieve frame, and change the original double sieve frame to a single sieve frame. The sieve is changed from the original 2 to 1 complete sieve. The material of the sieve bar is unchanged, but the reinforcement rib is integrally cast in the middle of the sieve bar to increase the strength of the sieve bar. After the transformation, the distance between the screen bars and the circumference of the hammer head has not changed. 3, the transformation effect Since removing the intermediate sub-half screen bar rack, coal pulverizer lime stone passing through the screen bars in the area increased by about 14%, to improve the crushing efficiency of the crusher, to improve the production station 65 ~ 75t / h. Limestone power consumption has been reduced from the previous 2.4kWh/t to 2.0kWh/t. It turns out that each hammer can only be crushed by 15,000 tons. After the transformation, due to the increase in production at the time of the Taiwanese, it is necessary to change the hammer by 2 hammers. Feeder, stone breaker manufacturer, crusher manufacturer The service life of the sieve rack and the screen rod was extended by half a year before the technical transformation. Since the original intermediate screen frame is easy to wear, it is often necessary to repair the welding, and the maintenance work is large and affects the production. Eliminating this problem after the transformation can save 2 packs of stainless steel electrodes per month.
