As classic crushing equipment, jaw crusher has many series with various types, so as to be suitable for different materials, output and different environmental conditions of crushing production.
Jaw crushers used heavily in the mining industry, often incorporate keyways and/or expensive sweat or press fit connections.Using traditional keyed connections introduces several compromises.Whenever a shaft is keyed, it must be oversized to account for the loss of effective cross section.This adds weight and cost not only to the shaft, but to every component on the shaft.Keyways cause fretting corrosion, allow backlash, do not transmit bending moments or axial loads.
A set consists of a special nut and three hexagon screws and replaces the normal hexagon nuts on each hammer head screw and spring unit.One tri-nut replaces two normal hexagon nuts.The number of hammer screw spring assemblies varies depending on machine / jaws.So if there are 16 spring assemblies in a c110 jaw mounting, there are normally 32 hex nuts.If you replace those with the tri nut solution, you will need only 16 tri nuts.Since 2019, almost all metso jaw crushers have been delivered with the tri-nut fastening system.Customer service is a mutual exchange, not just eliminating a specific customer problem, but also working together on the sustainable optimization of a situation in need of improvement.
Jaw crusher main features and advantages1) high efficiency and low operation cost 2) flexible capacity3) simple structure and easy to operate4) over loading protection 5) easy replacement of wearing parts 6) long service life 7) high reliability 8) wide ranges of choices9) alternative ordinary and hydraulic types.
In highway construction, a large number of high-quality sand and gravel aggregate, jaw crusher to provide important device security.Jaw crusher best suited to crushing compression strength is lower than the 280mpa the ore, rock, slag, and so on.The crushing chamber is symmetrical "v" shaped structure, practical into the discharge port width and nominal feed opening width is consistent; equipped with a crusher compared to the same specification of larger and more durable eccentric shaft bearings, higher carrying capacity and effective labyrinth seal and bearing life greatly extended; perfect whole cast steel bearing to ensure that the broken rack fully compatible with, but also greatly enhance the bearing radial strength, which is split bearing seat does not have.
Secondary broken: after the material jaw crusher evenly transported to cone crusher feed opening through feeder.Material will be broken by cone crusher.The material does not meet the size requirements continue to remain in the cone crusher, until compliance with granularity from the discharge port.
Vietnam 140 t/h river stone gravel sand production line is well-known in vietnam gravel sand production project, the production line using primary crushing jaw crusher, efficient hydraulic cone crusher for secondary crushing and vsi5x sand making machine.
Jaw crusher can crush all kinds of soft and hard materials with compressive strength between 300-350mpa, such as granite, quartzite, diabase, pebble, iron ore, etc.
The general configuration of the limestone crushing line is vibrating feeder + jaw crusher + impact crusher + vibrating screen + belt conveyor.In this crushing line, the most important component is the crusher parts for these parts are easily to be worn.Through the reformation of crusher part constructure, chemical component and casting processing technology, etc.Dsmac especially put forward to the new bole bar.In order to improve the wear resistance, the tungsten titanium alloy was coated on the surface of the traditional blow bars.Therefore, dsmac blow bar can resist the high abrasion in harsh working condition.Theblow bar has the following features:.
The purpose of mobile jaw crusher machineis to eliminate the obstacles brought by crushing site and environment to customers, adapt to the development demand of modern crushing industry to the maximum extent, improve production efficiency and play an important role in railway, highway and urban construction.
Our cone crusher includes symons cone crusher, hydraulic cone crusher, sprind cone crusher.Spring cone crushers are widely used in industries like metallurgy, construction, road building, chemistry etc, to crush many kinds of mid-hard or hard rocks and ores such as iron ore, limestone, granite, basalt, quartz etc.The standard ones are used for intermediate crushing; the medium ones are used for fine crushing; and the short head ones are used for super thin crushing.Compared with jaw crusher, spring cone crusher is of stable structure, high efficiency, easy adjustment, and economical using etc.The spring safety system of crusher acts as an overloading protection system that allows metals to pass through the crushing chamber so as not to damage the cone crusher.The safety system uses dry oil and water as two kinds of sealed formation to make plaster powder and engine oil separated to make sure reliable performance.This type of crushing chamber depends upon the size of feeding and fineness of the crushed product.The standard type (pyb) is applied to medium crushing, the medium type is applied to medium or fine crushing and the short head type is applied to fine crushing.
