Investigators say the employee was working on or near a rock crusher when his harness became tangled in a conveyor belt and he was pulled into the machine.This appears to be an accident, police say.
The impact crusher designed by our company are in the advanced level with the unique structure.And the final products are cubic shape and even size.Dealing with the material with the side length of 500mm, not more than 350mpa anti-pressure strength, impact crusher can be widely used in the first and secondary crushing.And it has found its extensive usage in the field of the chemistry,construction,mine crushing,energy,highway,and railway,etc.
Relying on advanced technology, our engineer transforms the original hammer crusher, making the equipment have better effect on crushing material.Our hammer crusher adopts the new steel.In the medium and fine crushing work for limestone, slag, coke and coal, the wear of the hammer is reduced and the service life of the hammer crusher is prolonged effectively.
The vibrator is made of two fixed eccentric shafts whose gears are jogged.When installation, the two gears must be jogged according to the sign.Through drive of the motor, the two eccentric shafts start rotating to produce a linear huge power which forces the feeder to vibrate.Through the vibration, the materials will slip and sling on the funnel, moving forward, when the materials pass the screening part, smaller parts will fall down, and avoiding the further crushing, so screening purpose can be reached.The vibrating feeder (vibratory feeder) is used to transfer the large size materials and granular materials from silo to receiving device uniformly, periodically and continuously in the production flow and to feed materials into the crusher continuously and uniformly also to screen the materials in the sandstone production line.The vibrating grizzly feeder is widely used to match the crushing and sieving equipments in many industries including metallurgy, coal mine, mineral dressing, building material, chemical, grinding, etc.Ore vibrating feeder can feed block or granule materials from the material storage to charging device evenly and continuously.It can realize even feeding for crushers in sandstone production line and make rough screening for materials.Widely applied in combined operation of crushing and screening in the industries like metallurgy, mine, mine ion, building materials, chemicals, etc.Working principle of china vibrating feeder:there are two eccentric shafts rotating at high speed at the same time from opposite directions, thus the strong centrifugal force is formed.The component forces of centrifugal force along the vibrating direction will always overlap each other, then counteract with that of vertical force from vibrating direction, then exciting force along single direction is formed to drive the feeder vibrate along straight line.When materials are fed into the feeder, they may be thrown up and move like para curve, then fall down.The materials will move forward on the slope surface of the feeder.Vibrating feeder consists of vibrating frame, spring, vibrator, motor vibrating device and motor.The air of the inflatable mechanical mix type flotation machine is blew into the flotation cell by external set of fans.Air inflation and mixing is separated.Its advantage is the large aeration quantity, low power consumption and can be adjustable.But it needs to add fan and pulp to return to the pump.The rotor of mix type flotation machine is similar with xjk type flotation machine, the rotor with several vertical leaf disc, cover the stator above, with several vertical guide blades.Air is blew into the top and bottom of rotor through the sleeve of stirring shaft by external pressure air fan.
According that whether classifier.Html">spiral separator is closed and its transmission lubrication condition, spiral separator can be divided into both open-type and close-type:open type spiral separator mesh is exposed, lubrication condition is not perfect,cement rotary kiln the gear easy to wear off spiral separator structure is simple, the ball mill, the rotary kiln, dryer, into balls set last level of transmission that belong to this.The above type spiral separator transmission mechanism in the installation must adjust on the site,single toggle jaw crusher in order to ensure that the two spiral separator gear meshing of normal.
The most important parts involved are impacted plate and hammer which experience severe abrasion because of strong impact energy.So the first way to prolong the life of the two parts is to choose the right equipment with high-quality and wear-resisting parts.Although the material of the impact plate and hammers in different manufactures looks same apparently, it is way too different in design.The excellent design would greatly reduce the abrasion if complete analysis and upgrade implemented on mechanical property and space design.The second method is applying impact rock crusher into secondary reducing after the primary crushing of fixed jaw crusher.The development of the mining industry and construction are in full swing, which raises higher demands on various mine resources in many countries.For example, elongated and flaky particle in final products must be less than 10% in many fields, which demonstrates the crucial role of impact rock crusher.
Aggregate crushing process plant mainly by vibrating feeder, jaw crusher, impact crusher, vibrating screen, belt conveyor and centrally electric control and other equipment components.Large stone by the hopper evenly sent by the vibrating feeder jaw crusher for primary crushing, stone after crushing by the belt conveyor to the crusher for further crushing; stone after crushing by the belt conveyor sent vibrating screen sifting, screening out of several different specifications of the stone.
The motor of the hammer crusher can be activated through the monitoring system developed on pc, both in manual and automatic mode.In particular, in the manual mode start/stop is controlled by the user, while in the automatic mode start/stop will be managed by the control software developed on plc.In both cases, the boot is regulated by a soft-starter and the actual supply will only be present if the disconnector placed on board of the machine is not in the service position.
When the meter shows that the bearing temperature exceeds the standard, the crusher machine should be stopped for inspection.
The tracked crusher uses the crawler to walk, enabling to realize in-situ steering.In addition, standard configuration and wireless remote control are equipped in the tracked crusher, making it easy to drive the crusher machine onto the trailer and transport it to the worksite.
In recent years, hongxing sand mechanical equipment involving multiple areas and fields, more export to overseas, and in these areas blossom and bear fruits, derivatived the potential business opportunities and customers.Along with the reform and development of national policy, the sand machinanical development course also in qualitative leap, while the expansion of this industry, indicated the real rise of sand mechanical, and the wealth wind.With its high quality products such as primary crusherssand washing equipmentvibrating grizzly feederhenan hongxing mining machinery co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
Impact crushers can work in a quarry one month, a concrete recycling plant the next, and then on a site where asphalt needs to be crushed after that.You can optimize your efficiency by mounting an impact crusher to a portable plant for a completely mobile crushing solution.These portable plants have a small footprint as a screen can be mounted on the same chassis as the crusher.
