Protection plates are designed for additional protection of the crusher’s frame and pitman. They are recommended when using small settings (always greater than or equal to the minimum recommended setting) and/or when the rock to be crushed is very hard (i.e. very low crushability). Of course, these can be used at any time for added…
The intermediate plate is an important jaw crusher wear parts. Fitting an intermediate (backing) plate behind the fixed jaw die reduces the nip angle of the crusher. The intermediate plate reduces the feed opening and the setting range by approximately the same amount as its thickness. However, the intermediate plate does not, under normal circumstances,…
Different jaw plates tooth profiles suit for different working conditions. If you want to decrease your cost, you must choose the right tooth profiles. Qiming Machinery’s engineers will show you which tooth profiles suit for which conditions. Standard Tooth Recommended Usage: Suitable for both rock and gravel crushing. Wear life, power requirements and crushing stresses…
Our customer, The Three Gorges, who have 2 sets of 50-65MK-Ⅱ gyratory crushers. This model was put into operation in August 1999. After the operation, all units responded normally. And because of its large crushing ratio and high productivity, it has become the main equipment for artificial sand and stone processing in this project. However,…
The large impact crusher has the advantages of simple structure, large crushing ratio, and high efficiency. It is widely used in mining, cement, metallurgy, electric power, refractory materials, glass, and chemical industries. The crusher blow bars are one of the keys and easy-to-wear parts of the large impact crusher. It is fixed to the rotor…
Crusher jaw plates are the main jaw crusher wear parts, and those are manufactured by high manganese steel. The as-cast microstructure of high manganese steel is composed of austenite A, carbide K and eutectoid structure, usually pearlite P. As-cast high-manganese steel, during cooling, a large amount of brittle carbides are precipitated at the grain boundaries…
The jaw crusher frame is the most important jaw crusher spare parts of the whole equipment, and the service life of the frame directly determines the service life of the equipment. The frame structure of the jaw crusher the frame of the jaw crusher is divided into integral frame and combined frame according to the…
Different crush stone, different work conditions, need to select the right material suit to cast crusher jaw plates. For example, Mn14 jaw plates can crush soft stone, but can not suit to crush hard stone, because it wears out speed too quickly if use Mn14 jaw plates to crush hard stone. Qiming Machinery can supply…
Jaw plates include a fixed jaw plate and swing jaw plate, which are the main jaw crusher wear parts. They need to exchange very regularly. When & How to change jaw plates? When to change jaw plates? There are two situations that need to change the jaw plates. In order to prevent damage to the…
The perfect circumstance would be when even put-on occurs throughout the jaw plate location, making use of all the manganese teeth, eliminating the demand to execute the “turn”, or modification manufacturing. This is difficult, however, due to the fact that there are locations where we can not stay clear of a lot more extreme wear…
