Abstract
The invention discloses a method for independently producing sand by using a vertical shaft impact crusher. The method comprises the following steps: firstly, feeding a stone machine stored in a transfer cabin to a constant-speed vertical shaft impact crusher; grading the crushed stones through a screen grader, and returning all the crushed stones of which the particle sizes are greater than 5mm to the transfer cabin; feeding a part of stones of which the particle sizes are 2.5-5mm to a high-speed vertical shaft impact crusher through a belt conveyer to crush again; and feeding the recrushed stones and a part of stones of which the particle sizes are 2.5-5mm and smaller than 2.5mm into a finished product cabin in a mixing manner. Thus, the stones in the product bin are uniform in particle size distribution, and the yield is increased and the energy consumption is reduced under the premise of ensuring excellent sand.
Description
Technical field
The present invention relates to a kind of method of broken sand processed, particularly a kind of method and device that utilizes vertical shaft type impact crusher independent sand manufacture.
Background technology
In recent years, along with the development of national basis Facilities Construction, Sand for Concrete demand is anxious to be increased, due to the closely exhaustion and non-renewable in the short time of existing natural sand resource, therefore the status of Machine-made Sand in engineering is more and more important, becomes the important sources of building with sand.Especially for the how Highway Construction in Mountainous Area of the few stone of sand, imperative especially with made sand to substitute natural sand concrete batching, Machine-made Sand production line becomes the new lover on market! In sandstone after the fragmentation of existing sand standard-required processed, particle diameter is wanted evenly at the gravel content of 0.075mm-5mm, for solving the uniform problem of gravel size, existing conventional sand system kind processed is a lot, thereby common a kind of be with two rod mill sand processed, to control the modulus of fineness of aggregates, another kind is with vertical shaft type impact crusher and rod mill joint sand manufacturing, but these two kinds is typical case and conventional sand system schema processed, all has the problems such as cost is high, efficiency is low, not environmental protection.
Summary of the invention
The technical problem to be solved in the present invention is, a kind of method of utilizing vertical shaft type impact crusher independent sand manufacture and device guaranteeing can reduce costs, raise the efficiency under the prerequisite of sand standard processed is provided, and can overcome the deficiencies in the prior art.
Technical scheme of the present invention: the method for utilizing vertical shaft type impact crusher independent sand manufacture is first to send being stored in the building stones machine that turns feed bin into constant speed vertical shaft type impact crusher, building stones after fragmentation are by screening machine classification, wherein the building stones of broken rear particle diameter > 5mm all return and turn feed bin, it is broken again that the part building stones of particle diameter in 2.5～5mm are sent into high speed vertical shaft type impact crusher by belt feeder, through broken again building stones and building stones and the < 2.5mm building stones of another part 2.5-5mm, be mixed into finished bin, can make like this building stones particle diameter in finished bin be evenly distributed, under the prerequisite that guarantees high-quality sand, improve output, reduce energy consumption.
The above-mentioned method of utilizing vertical shaft type impact crusher independent sand manufacture is that the rotating speed of the High Rotation Speed rotor of high speed vertical shaft type impact crusher is
, through the medium sand that obtains 0.63-2.5mm of its fragmentation.
Utilize the device of vertical shaft type impact crusher independent sand manufacture, it comprises and turns feed bin, turning feed bin is connected with constant speed vertical shaft type impact crusher by batcher, at the discharging opening place of constant speed vertical shaft type impact crusher, be provided with the screening machine more than two-layer and two-layer, the upper strata discharging opening of screening machine with turn feed bin and be connected, two layers of discharging opening are connected with tripper, bottom discharging opening is connected with batch mixing belt: an outlet of tripper is connected with batch mixing belt, another outlet is connected with high speed vertical shaft type impact crusher, the outlet of high speed vertical shaft type impact crusher is connected with batch mixing belt, batch mixing belt is connected with finished product bin.
The aforesaid device of vertical shaft type impact crusher independent sand manufacture that utilizes is that the discharging opening of constant speed vertical shaft type impact crusher is connected by conveyer belt with screening machine.
The aforesaid device of vertical shaft type impact crusher independent sand manufacture that utilizes is that described tripper is one-to-two tripper.
Compared with the prior art, applicant finds in long-term work, adopt the building stones reason not up to standard after vertical shaft type impact crusher fragmentation to be, there are many, the middle few polarizations in obvious two, what be particle diameter at 2.5-5mm and 0.63-0.16mm is more, 0.63-2.5mm's is less, thereby can not adopt separately vertical shaft type impact crusher sand processed.For the problems referred to above, the present invention sends being stored in the building stones machine turning in feed bin into constant speed vertical shaft type impact crusher, building stones after fragmentation are by screening machine classification, wherein the building stones of broken rear particle diameter > 5mm all return and turn feed bin, it is broken again that the part building stones of particle diameter in 2.5～5mm are sent into high speed vertical shaft type impact crusher by belt feeder, through broken again building stones and building stones and the < 2.5mm building stones of another part 2.5-5mm, be mixed into finished bin, utilize like this vertical shaft type impact crusher just can fundamentally solve the problem of the modulus of fineness of aggregate, and in production efficiency, also there is very large lifting, operating cost also has obvious reduction, energy-conserving and environment-protective have been realized simultaneously, economic and practical contribution.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
