Crushing limestone generally choose the hammer crusher, but there are some shortcomings of the traditional hammer crusher, Unique today for pc1000 × 800 hammer crusher shortcomings, combined with the use of it in the actual production situation, to make a few modified opinion:A sieve frame lengthened 160mm, can screen bars arranged four to increase the a hammer crusher acting area, qualified size products in a timely manner to discharge the crushing chamber, reduce crushed generated, to reduce the load of crusher machine easy to increase production capacity.
The overall structure of a second upper rack is replaced by a split structure, this structure so that maintenance rotor is very convenient, and need only move out to the left part of the split portion hanging out rotor. The retrofit should note, cut the upper rack, plus a pair of flanges when welding, require the removal of the stress to ensure the performance of the overall assembly. Sieve frame radian R520 changed to R510, reduce the gap of the screen bars with hammer, sieve frame at the same time easy to adjust screen bars rack can be enough to adjust the position when the hammer wear.
The three the surfacing reinforcement sieve strip frame and screen bars. Hardfacing electrode surfacing reinforcement screen frame installation location of the sieve frame, screen bars, easy to wear face surfacing about a height of 5 mm, while the screen bars welded shelves fixed on the screen bars to prevent screen The bar rack deformation, the screen bars scattered, fixing protective effect. Such improvements can greatly extend the the grizzly bar frame and screen bars the use of time, reduce material consumption.
4) hammer crusher rotor static and dynamic balance test, install combat balance hammerhead, this improvement is an important way to solve the hammer crusher vibration. The basis of the basis of its drive motor of the hammer crusher together as a whole, the use of concrete masonry, to enhance its anti-vibration performance, avoid vibration damage base, in order to ensure the use of the Yuanhua hammer crusher performance.
After transformation, in particular broken limestone effect obviously the most significant, the effective increase in the amount of wear of the hammer, the improved utilization of crushing the increase in production, and to extend the usage time of the screen bars the frame and the screen bars.
