Detailed Introduction Of Upgrade Crusher Mobile Crusher

The most effective way to load a mobile crushing unit can be chosen according to the site conditions, and local preferences.Due to the site mobility the mobile crusher is ideally suited for being loaded by a hydraulic excavator in backhoe operation.In the typical application of the excavator, the operator is able to control the crusher with a remote radio device from his cabin.The operator of the excavator is able to perform a relocation of excavator and ipcs during production normally in less than 5 minutes.Another advantage of this type of operation is that the operator is based on a higher level than the feed hopper.Therefore he can control feed size and separate oversized material with the bucket.In addition the operator, while digging, is able to check if the correct material level is reached in the crusher and bed height on the grizzly bars is sufficient.These major advantages, in contrast to other operations, lead to the point that by using a backhoe operation the correct feed rate can be maintained during the production and therefore ensure higher productivity.The robust construction of mobile crusher also allows for the use of conventional loading machines e.G.Wheel loaders.In applications where the mobile crusher is relocated frequently and the wheel loader is chosen for loading, building an access ramp to the feed hoper is time consuming and expensive in the long run.A better way to solve this problem of building ramps and "not visible" feed hopper for the wheel loader operator is a mobile apron feeder.With this piece of equipment, loading can be done directly from ground level and furthermore the driver can clearly see if the feed figure 2: multi bench operation hopper is overloaded or not.This technique is used when short cycle times are necessary and the blasted material is fine and homogeneous.The moving interval of this application lies in reference to the demands within 15 days.Even loading methods, which are using a dump truck or excavator with face shovel, are not excluded from feeding a mobile crusher.The face shovel is not the dedicated excavator for feeding the mobile crusher, because most of the time the operator is not able to look into feed hopper.As a consequence, experienced operators, who take care of their work, are highly recommended.Another aspect of using face shovel excavators is that the machine itself is normally a bit oversized for the mobile crusher.This is because the loading cycles would otherwise be too long.If an excavator is used, which is just able to match the requirements of height and distance at highest extended point, the boom of the excavator has to always make a very long swing from the bottom to the top of the feed hopper.As an alternative to selfpropelled crushers, semi mobile units can also be used in pit crushing.These units are suitable in fields of application, when the relocation interval varies from 0.52 years.In semi mobile applications the crushing unit is loaded with dump trucks.The dump trucks perform the short distance haulage, which enables selective mining.The long distance haulage is after primary crushing and is done with conveyor belts.That constellation reduces the haulage costs very efficiently.The relocation of the semi mobile unit is assisted by a special carrier unit.The carrier unit is driven under the semi mobile crushing unit and lifts it up by help of hydraulic cylinders and carries it to the new location.Larger quarries or mines, which need several semi mobile crushing stations in different parts of the pit can use one carrier to move all units and fulfil the capacity requirements.A fully mobile crusher can also be converted into a semi mobile unit by using a skid mounted feed hopper.This feed hopper is very large, so that dump trucks can unload the raw material directly.Basically there are three different types of primary crushing units to choose from.Mobile crushers are manufactured and delivered as jaw, impact or gyratory crusher.The gyratory crusher at first was implemented for secondary crushing, but will be soon available for primary crushing too.Depending on the pit demands the engine can be diesel powered and reach up to 645 kw or can also be electric powered.The travel speed of the track gear is approximately 1 km/h and the mobile crushing units are able to incline 20° or 35%.The throughput for jaw crushers can range up to 1800 mg/h depending on the feed material.The weight of mobile crushers varies from about 60 mg to more than 200 mg.Normally jaw crushers are equipped with a vibrating feeder, a bypass to keep small fractions away from the crushing process, the crusher itself, and a main conveyor.Depending on the manufacturer and the individual needs more equipment can be ordered.For example, screens to be placed in the bypass can be bought to scalp out waste material at an early stage of the process.Unnecessary haulage into further processes is thereby avoided.Using screens in the bypass only makes sense if there is a second discharge conveyor installed.In addition to this linking adapter for the mobile conveying system, money could be spent for such things as: dust encapsulating, magnetic separator, hydraulic hammer, driver cabin, several supporting stands, if needed.According to the needs of a mobile conveying system an electric generator must be bought too, because power supplied to the conveyor belts are normally comes from the mobile crusher units.As the professional manufacturer of complete sets of mining machinery, such as china jaw crusher,china dryers,china mobile crushers,sand washer supplier,vibrating grizzly feeder, henan hongxing is always doing the best in products and service.Mobile crushing station:
