aggregate production processing
aggregate crushing 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.
concrete aggregate production line
the crushers conduct a crushing operation in three stages – primary, secondary and tertiary. this ensures production of aggregates with desirable physical characteristics. using state-of-the-art cyclone washing system to wash sand, the silt content is reduced to the permissible limits.
besides coarse and fine aggregates, granular sub base and aggregate base course materials are also produced. granular sub base and aggregate base course materials comply with general specifications for roads.
aggregate crusher equipment
double machinery is a premier supplier of crushing and screening equipment, and related auxiliary equipment in china. we provide complete crushers and screen machineries for producing all types of aggregate, we also can supply the complete turn-key aggregate production circuit.
the major aggregate crusher equipment is:primary jaw crusher;secondary jaw crusher, secondary impact crusher;tertiary cone crusher, fineness cone crusher;vibrating feeder, vibrating screen, belt conveyor;complete stationary, portable, mobile aggregate crushing equipment are available. our aggregate crusher equipment with iso and ce certificates have been sold to over 100 countries around the world. besides, we have established branch offices in many countries. we have different crushing plants, our professional staff will offer suitable solutions according to your requirements.
cement rotary is the main equipment in the dry production line of clinker cement. this series of rotary kiln consist of bowl, supporting part, supporting device with catch wheel, gearing rigging, flexible kiln hood, kiln hood and kiln end sealing device, nozzle device and so on. the rotary kiln is higher than the horizon as the whole body is supported by the riding wheel with the catch wheel controlling the up and down move of the kiln body. besides the main transmission, the transmission system sets auxiliary transmission device which can keep the kiln body move when the main power is off to protect it from bending deflection. the kiln hood and kiln end sealing device adopts advanced technology which ensures the security of the sealing.
crush the zinc charging and the coke coal into powder lot less than 40. mix the zinc charging with the coke coal pro rata 1:0.30~1.35 evenly and make the mixture into granule with diameter being 8-15 mm. in the end, put the granule into the brick kiln to smelt and produce zinc oxide. this technics greatly saves the coke or fire coal. the product gained by smelting is of fine quality and high productivity.
according to the kinds of stones, the aggregate can be classified into many kinds, such as basalt aggregate, granite aggregate, limetsone aggregate, river stone aggregate, cobble stone aggregate, sand stone aggregate and slate aggregate etc.
according the aggregate heavy degrees, the aggregate can be classified into coarse aggregate and fine aggregate.
fine aggregate: the grain size is below 4.75 mm, also called sand. according to the source, there are natural sand and artificial sand. the natural sand is the rock particles whose grain size is below 4.75 mm, formed by natural weathering, potamic transport, separation and stockpiling. the artificial sand is the general terms of mechanism sand and mixing sand that go through the soil removing .
coarse aggregate: the grain size is above 4.75 mm, also called rock. the common coarse aggregate are gravel and pebble. the gravel is the rock particles whose grain size is above 4.75 mm, formed by the natural rock or river stone crushing and sieving.
aggregate product line equipment
the aggregate production equipments mainly consists of efficient crushers, such as jaw crusher, impact crusher and cone crusher. there are other auxiliary equipments, such as storage bin, vibrating screen, feeding machine and belt conveyor.
some aggregates need auxiliary process, including washing, swirling sand washing machine and rotary screen. the main purpose is to make the final products more clearer. thick powder separator and dust-cleaning apparatus can be equipped if using dry production process.
aggregate production processing
material taking: through blasting, the qualified rocks are fractured into pieces for crushing.
conveying: after blasting, the stones are transported to the broken factory by tip lorry or belt conveyor. or the conveying is the internal materials input process in each links.
crushing: using all kinds of crushers or rod mill or ball mill to crush the materials so that the materials will be smaller to meet various specifications demands.crushing is the most important link in aggregate production process and is also where the aggregate production equipment fully plays its role. in addition to various types of crusher and auxiliary equipments, the vsi5x new sand machine researched by sbm machinery is the necessary machine for producing the quality sands.
screening: sorting in the production process. through various specifications of vibrating screen, the qualified materials are selected out then transported to the corresponding materials heaps. the unqualified materials are sent to crushers for next crushing.
drying: drying the aggregates which size and shape are qualified, in order to make the moisture content reach to relevant requirements. generally speaking, the coarse aggregate needs natural drying. the fine aggregate(coarse sand and fine sand) needs dryer equipments.
storage: the produced aggregates, which meet all kinds of specification requirements, are stored separately. for the different requirements for containing moisture and operating and environment condition, the open storage can be used and the storage bin or vertical shaft can be used for storage.
in the six working procedures, conveying, crushing and screening often are repeated. the processing flow can be summarized as screening repeated, crushing repeatedly and directional conveying.
aggregate is granular loose materials whose total volume is the 60% ~ 80% of concrete volume. as the main raw material of concrete, the aggregate plays a role as skeleton or support in the concrete.the aggregate plays an important role in building. when mixing the materials with water, the cement will be thin paste after mixing. if the aggregat is not added, the cement will not be able to shape and not available. so we can say that the aggregate is very important.
sbm machinery provides professional aggregate production equipments and comprehensive technical support for you. we design the various types of equipments in order to meet the customer’s different process requirements.
for aggregate customers, the combination of sbm and hartl powercrusher adds new possibilities.
sbm offers drill rigs from the smallest handling 76 mm holes to the biggest drill rig handling up to 140 mm holes.
the majority of the drill rigs uses the tophammer drilling method, but some also use down-the-whole or coprod methods in order to provide the best solution for the various conditions faced in this application area.
sbm also now offers crushers using three different crushing methods, and screeners using these units in both primary and secondary applications – as follows:
jaw crushers with inlet openings ranging from the smallest of 1000- 550 mm to the biggest that has 1300 –800 mm
impact crushers with inlet openings ranging from the smallest of 1000- 600 mm to the biggest that has 1560 –1020 mm
cone crushers with an inlet opening diameter from the smallest of 1000 mm to the biggest that has 1300 mm
screeners with mesh sizes ranging from the smallest of 3650- 1500 mm to the biggest that has 6340 – 1500 mm.
