Six ways to Improve Efficiency of Roll Crusher

Roll Crusher, also known as roll sand maker, whose maintenance is a regular work, and the maintenance work have a direct impact on the roll crushers operation rate and service life. In order to detect the deficiency, eliminate hidden dangers and ensure the normal operation, we should do routine maintenance as well as periodical overhaul, now, let us follow Hongxing experts to see how to maintain it and more effectively improve the crusher efficiency.

1. If it is long-term disabled, or initially started, please turn the large pulley 2-3 cycles in advance by manpower, make sure the machine is running freely, and start motor for a few times until motor rotates to correct direction, and then officially launch the crusher.

2. Do regular spot checks to exam whether the crusher product size is qualified. If necessary, re-adjust the spacing between crushing rollers.

3. When normal shutdown, stop the machine till all materials are expelled from crusher.

4. Lubricate main and sub-transmission gear box with gear oil, timely replace lubrication in summer and winter.

5. If it is necessary to open main and sub-transmission gear box when maintaining and repairing, please ensure to replace the rubber seal and evenly spread a layer of sealant on stationary seal surface to prevent oil impregnating or oil spilling in the sealing surface.

6. After maintenance, please tighten torsional moment when re-assembly upside crushing roller and clamping coupling. In addition, what need to pay attention is that tightening diagonal bolts first, and then tightening the middle bolt, while the coupling gap on both sides of the sub-surface should be uniform.

High-efficiency hammer crusher is important equipment in fine crushing field and mainly used for material fine crushing. Making PX high-efficiency fine crusher as an example, hammer head is with split structure, which makes replacement convenient; Hammer head and handle are connected by bolt. Hammer head materials adopts Cr Mo alloy of high wear resistance whose wear-resisting performance is best among hammer crushers.

Sand maker

Sand maker is the most traditional type of hammer crusher, whose hammer head is directly connected to rotor through the rod. In order to avoid the breaking of hammer head, head material hardness cannot be too high. Therefore, its hammer head wear-resistant cycle is shorter than high-efficiency hammer crusher.

Vertical shaft hammer crusher

Its advantage of no-plate structure makes it avoid blocking phenomenon. But its crushing effect is slightly lower because hammer head and liner plate cannot form large angle counter process. The hammer head is an integral-structure one, so the repair and maintenance are complex.
