At the initial stage, the sand is crushed by coarse crusher, transported by belt conveyor into fine crusher for secondary crushing.The concerned material is screened and selected by vibrating screen.During the process, the material that fits the feeding size will be handed to sand maker and the remaining will be returned for secondary crushing.Usually, 25-45% of the fed material turns out as the final product after crushing and washing.The rest will be handed and fed into sand maker again.
4.The hammer of composite crusher.Hammer handles using the low alloy, high strength and high toughness; hammer use of the wear-resistant materials, give full play to the advantages of two materials, make use of the composite technology to combine the two together, expanding the application scope of high wear- resistant materials, so that increase the working life.
Crusher run also known as crush and run, comes from georgias vast granite deposits.This item is gray in color, made up of granite dust, #57 granite stone and #4 granite stone mixed together.The texture of the crusher run stone allows for excellent compaction, which in turn creates a solid, steady base that will support pavers exposed to constant traffic.
Next, better dust removal effect.According to the service life of the filter material and the pulse valve, it is necessary to consider the dust of the ash.In order to improve the comprehensive dust removal effect of the compound crusher and the belt machine, when crushing dry materials, water is properly sprayed at the material inlet of the compound crusher machine(required to be carried out 10 to 20 minutes after the combination crusher being started).

From the above, it can be seen that the direct-selling manufacturers are more favorable in price.Also, for direct-sales manufacturers, the problems of after-sales and accessory support of mobile crushers can be better guaranteed.
With the fast development of china's economy, the management force of the scare mineral resources in our country has been intensifying.As one of the national strategic reserve resources, the reserve and production ratio of the fluorite in recent years has been keeping decreasing.With the wider and wider application of fluorine, the application value of fluorite will become more and more important.Then the government in our country begins to intensify the protection force of the fluorite minerals and the crushing and the fluorite and the powder grinding and processing equipment will be influenced in the large-scale integration process.For this reason, improving the market application ability of such products as the fluorite crusher and grinding machine is a new lesson that is put forward to the fluorite processing equipment manufacturing companies.
However, faced with the benefits of the domestic market, the competition coming from the foreign impact crusher manufacturers that swarm in to china for investment and expansion can never ignored, so that experts in this industry must keep a clear head.Seen from the current situation, although competition has some incentive effect to the ball mill to innovates equipment and change the management and operation, low-level price competition gives opportunity to rough-made machinery to go into the market, which not only damages the image of the domestic brand in the market, but cause confusion to the market, all which is not helpful to the healthy development of this industry.So increasing independent innovation ability, improving the product performance and quality and developing the self-hold brand in order to respond to the market competition is the key question faced with this business scope.
The crushing ratio of hammer crusher is 10-25, the content of needle and flake is more, and the powder content is higher.
Matters need attention when starting a sand making production line : after preparation, according to the provisions of the driving sequence operation to start the main motor, when starting the motor we shoul pay attention to the current meter of the control cabinet, after starting the peak current for 30-40s, the current will reduce to a normal operating current value.In the normal operation, we also should pay attention to current which should not be more than the specified value.After the normal operation of the jaw crusher, it can actuate the feeding machine, and according to the block size and the operating condition of the jaw crusher adjust the feeding machine belt and change the feed quantity.Usually, the material stacking height in the crushing cavity should not more than the 2 / 3 of crushing chamber, and the diameter of the materials should not be more than the 50%-60% of the inlet width, the jaw crusher has a highest production capacity at this condition.When the materials with larger piece, it will cause blockage affecting the normal production.To prevent metal ( such as the spade teeth, crawler plate, bits ) from entering the jaw crusher and avoid damaging the machine, it should be brought out when they pass through the jaw crusher to prevent causing accident; when the electrical equipment automatic trip, if the cause is unknown, forbid forced continuous starting.
Our salesman gave him detailed information about the hammer crusher.He was very satisfied with our equipment.
