Problems solved by technology

At present, the production of each specification of stone or sand is carried out independently, that is, a producer or a set of production equipment can only produce one of the products or one specification of a certain product, and the user is carrying out construction activities Sometimes it is necessary to obtain all the required raw materials through various channels, which is laborious and laborious, resulting in low efficiency of construction activities

Embodiment 1

[0040] figure 1 It is a flow chart of the steps of a sandstone aggregate production process embodiment provided by the present invention.

[0041] refer to figure 1 As shown, the sand and gravel aggregate production process provided in this example is used to use the ore collected from the mountain to produce the sand and gravel aggregate required for construction. , finished sand, etc. This process requires the use of the preset first intermediate silo, second intermediate silo, third intermediate silo and fourth intermediate silo. The specific process is as follows:

[0042] S101: Collect dolomitic limestone raw material ore from the mountain.

[0043] The production basis of this process is the raw material of dolomitic limestone. In order to save costs, this process adopts the method of collecting the above-mentioned principle minerals from the mountain, thus avoiding the transportation and purchase costs required for importing from other places.

[0044] The steps of c...

Embodiment 2

[0079] figure 2 It is a flow chart of the steps of another sandstone aggregate production process embodiment provided by the present invention.

[0080] refer to figure 2 As shown, the sand and gravel aggregate production process provided in this embodiment is improved on the basis of the previous embodiment. Compared with the first embodiment, the following steps are added.

[0081] S112: washing and screening the finished composite clay.

[0082] In view of the fact that there are still some mineral materials in the composite soil, the function of this step is to make full use of the mineral materials. Specifically, washing and sieving the finished concrete by using a washing sieve, so as to separate mineral materials of different sizes for further utilization. Mineral material and mud with a size larger than 1 mm can be obtained through the sieving treatment of the washing screen, and the mud contains mineral material smaller than 1 mm, but it has no use value.

Abstract

The embodiment of the present invention provides a sand and gravel aggregate production process, the process uses the first intermediate silo, the second intermediate silo, the third intermediate silo, the fourth intermediate silo, multiple crushing devices and multiple Screening device. Among them, the above-mentioned intermediate silo, crushing device and screening device are respectively connected through corresponding belt conveyors to realize the flow of mineral materials between the crushing device, screening device and intermediate silo, and finally output the corresponding Finished concrete, finished crushed stone, finished rice stone and finished sand can obtain all the sand and gravel aggregates required by users for construction activities, and users do not need to obtain them through various channels, thus improving the efficiency of construction activities.

Description

technical field [0001] The invention relates to the technical field of mines, in particular to a sandstone aggregate production process. Background technique [0002] Sand and gravel aggregate is an indispensable and important building material in the construction industry. Among them, the compound soil used for roadbed filling, crushed stone and sand and gravel used as ingredients for concrete are all within the scope of sand and gravel aggregate. The gravel and sand used as concrete ingredients alone require several specifications of stones and sand. At present, the production of each specification of stone or sand is carried out independently, that is, a producer or a set of production equipment can only produce one of the products or one specification of a certain product, and the user is carrying out construction activities Sometimes it is necessary to obtain all the required raw materials through various channels, which is laborious and laborious, resulting in low eff...
