Abstract
A kind of Machine-made Sand production technology, step 1: raw material are screened for the first time, are removed impurity and clast therein, are obtained block stone；Step 2: obtaining rubble for the progress coarse crushing of block stone, crushed stone carried out postsearch screening, and the coarse crushing again of the rubble greater than 400mm is broken less than in the progress of the rubble of 400mm until being less than 400mm, obtains product one；Step 3: screening product one three times, will be greater than 10mm rubble re-start in it is broken, until be less than 10mm, by less than 10mm carry out it is fine crushing, obtain product two；Step 4: product two is subjected to four screenings, the sand less than 3mm enters sand washer, and the sand of 3-10mm enters sand washer after carrying out the sand fine crushing for being made smaller than 3mm again；Step 5: finished product is obtained.There are stronger robustness and durability by the sandstone that the production technology obtains, product granularity is more uniform.
Description
Technical field
The present invention relates to a kind of production technology, specifically a kind of Machine-made Sand production technology belongs to Machine-made Sand technology of preparing neck
Domain.
Background technique
It is estimated that the existing annual building aggregate dosage in the whole nation is about 9,000,000,000 tons, the first in the world is accounted for, increasingly with capital construction
Development passes through the exploitation of decades in many areas in China, and limited natural sand resource has been used up, and price rises steadily, shadow
The development for having rung engineering construction, for the protection to environment and resource, country and various regions government strictly limit or forbid exploiting day
The appearance of right sand regulation and policy, further reduces the source of natural sand, so in all parts of the country carry out Machine-made Sand.
Machine-made Sand refers to the sand being process by sand making machine and other auxiliary devices, and finished product is more regular, Ke Yigen
The sand for being processed into Different Rule and size is required according to different process, is more able to satisfy daily demand.Machine-made Sand will have setting for profession
It is standby just to produce qualified applicable sandstone.
But the Machine-made Sand processing process produced and processed at present is simple, the robustness for the sandstone produced and durable
Performance is poor, and product granularity is also uneven.
Summary of the invention
In view of the above existing problems in the prior art, the present invention provides a kind of Machine-made Sand production technologies, by the production work
The sandstone that skill obtains has stronger robustness and durability, and product granularity is more uniform.
To achieve the goals above, the technical solution adopted by the present invention is that: a kind of Machine-made Sand production technology, including following step
It is rapid:
Step 1: raw material are screened for the first time, are removed impurity and clast therein, are obtained block stone；
Step 2: the progress coarse crushing of block stone is obtained into rubble, crushed stone is subjected to postsearch screening, the rubble weight greater than 400mm
New coarse crushing, it is broken less than in the progress of the rubble of 400mm until being less than 400mm, obtain product one；
Step 3: screening product one three times, will be greater than 10mm rubble re-start in it is broken, until being less than
10mm, the carry out less than 10mm is fine crushing, obtain product two；
Step 4: product two is subjected to four screenings, the sand less than 3mm enters sand washer, and the sand of 3-10mm carries out again
Fine crushing be made smaller than after the sand of 3mm enters sand washer；
Step 5: finished product is obtained.
Coarse crushing in the step 2 uses jaw crusher.
It is broken in the step 2 and step 3 to use impact breaker.
It is fine crushing using impact sand production machine rod mill in the step 3 and step 4.
Each cargo handling operation has dust exhaust apparatus.
Sand production line automation degree processed of the invention is high, and operating cost is low, and percentage of damage is high, and energy conservation, yield is big, pollution
Few, maintenance is easy, and the Machine-made Sand that sand production line processed is produced meets national building sand standard, and epigranular, particle shape are good, grade cooperation
Reason.
Specific embodiment
A kind of Machine-made Sand production technology, comprising the following steps:
Step 1: raw material are screened for the first time, are removed impurity and clast therein, are obtained block stone；
Step 2: the progress coarse crushing of block stone is obtained into rubble, crushed stone is subjected to postsearch screening, the rubble weight greater than 400mm
New coarse crushing, it is broken less than in the progress of the rubble of 400mm until being less than 400mm, obtain product one；
Step 3: screening product one three times, will be greater than 10mm rubble re-start in it is broken, until being less than
10mm, the carry out less than 10mm is fine crushing, obtain product two；
Step 4: product two is subjected to four screenings, the sand less than 3mm enters sand washer, and the sand of 3-10mm carries out again
Fine crushing be made smaller than after the sand of 3mm enters sand washer；
Step 5: finished product is obtained.
Coarse crushing in the step 2 uses jaw crusher.
It is broken in the step 2 and step 3 to use impact breaker.
It is fine crushing using impact sand production machine rod mill in the step 3 and step 4.
Each cargo handling operation has dust exhaust apparatus.
The present invention is uniform from storage bin by blocky, feed particulate material by oscillating feeder, timing, is continuously given to receipts
Expect to screen raw material for the first time in the process in device, remove impurity and clast therein, obtain block stone；Jaw
Crusher is the rock crushing plant most generally used in the world at present, and the medium size for being mainly used for various ores and bulk materials is broken
It is broken, with the spy that structure is simple, maintenance is easy to use, performance is stable, operation cost is low, product granularity is uniform, reduction ratios are big
Point；Impact breaker utilize impact energy broken material, equipment work when rotor high speed rotation under the drive of motor, from into
The bar on material and rotor that material mouth enters is hit, and the high speed impact by bar is broken, and broken material is again anti-
It hits on liner plate and is crushed again, be finally discharged from discharge port；Sand washer can remove the mud in Machine-made Sand can be with controlling mechanism
The powder containing quantity of sand.
