The jaw crusher is the first choice for the crushing of ore in the gravel production line. In the gravel production line, the jaw crusher is generally used for coarse crushing of ore. Compared with the general ore crusher, the jaw crusher can be broken. The ore is relatively hard and has a relatively large feed. Due to the harsh environment of the jaw crusher during use, the crusher manufacturer reminds the users to pay attention to it, and it is necessary to pay attention to the dust pollution problem of the jaw crusher.

In order to reduce the dust caused by air leakage from the crusher casing, in actual production, when the material is dry, water is often poured at the inlet of the crusher. In fact, this situation is wrong, which will aggravate the bag filter of the jaw crusher. The filter bag and the feeder are clogged.

During the falling process of the ore and other materials on the belt conveyor, the air enters the sealed dust hood together with the material, and the dust-containing gas diffuses outside the cover through the gaps and holes in the cover wall. In addition, due to the improper setting of the dust removal point at the corner of the belt conveyor The dust collector has almost no effect on the dust of the lower belt conveyor regardless of the opening and closing. Since the operation of the jaw crusher, the dust collector has not been operated, and the lower belt conveyor has been in the process of dust pollution.

When the crushing material of the crusher machine has a large humidity, the elbow portion is easily worn by the dust and the dust particles that are blocked into the dust collector are thicker than the broken dry material, and the bag type dust remover is easy to paste the bag, and the feeder is easy to block. As a result, the ventilation resistance of the bag filter is greatly increased, and the ventilation capacity is lowered, resulting in wear of the jaw crusher.

1. Lead-containing surface of the welded part is ground with a grinding wheel by 2~3mm.

2. When welding, try to avoid the parent body being heated too much, and hammering the welding after welding to eliminate the internal stress of the welding.

3. The order of surfacing is to first weld one layer on all the teeth on the tooth plate, and then weld the second layer, instead of welding all the surfacing layers of one tooth first, then welding one tooth. Avoid welding deformation of the mother body that is too hot or too large. The speed of surfacing should be fast, the lateral oscillation should be small, try to use small-diameter welding rod and small welding current, and the cooling speed after welding should be fast. When conditions are met, the high-manganese steel casting can be placed in water, and only the surfacing part is exposed. If conditions permit, it is best to carry out quenching heat treatment after welding.

The jaw crusher has always been an important crushing device for the coarse crushing process in the stone production line and the sand production line. Since the feed port of the jaw crusher is large, it is a primary crush in the crushing production line, which shows his importance. The traditional PE series jaw crusher is a toothed plate extrusion type of round-trip crushing, and the broken material can only meet the requirements of entering the impact crusher and fine crusher for crushing production. Therefore, he is usually in the stone production line. The highest point is broken.As a new generation of high-performance crusher, jaw crusher surpasses traditional E-break in performance, maintenance cost and structure, and can be widely used in metal and non-metal mines, cement, construction, sandstone, metallurgy and other industries. PE series high-energy rupture is used in the production process of building gravel and machine-made sand, especially when crushing hard materials such as basalt, it has higher production efficiency and lower running cost than traditional smashing.According to the principle of the PE series jaw crusher, a buffer spring is added to the back, so that it can play the role of buffering the pressure during the production, which further increases the particle size and the degree of extrusion, if it is in production. When the discharge is too large, only the adjustment of the bolts behind will strengthen the discharge particle size of the entire stone production line to alleviate the pressure of the secondary crushing to achieve the overall production efficiency improvement, and the discharge granularity is uniform.
