Embodiment 1

[0031] Refer to attached figure 1 with 2 , Limestone, granite and river pebbles of different particle sizes are selected as raw materials for sand making. The raw material conveyor 2 sends the above-mentioned raw materials in the storage bin 1 to the impurity separator 3 for impurity separation, and then enters the jaw pre-crusher 4 to pre-crush the separated stone raw materials to a size range smaller than about 80mm, and then passes through The raw material conveyor 2 sends it to the fine crusher 5 for sand making, and the raw material smaller than about 80 mm is crushed to smaller than about 25 mm by the fine crusher 5, and is transported to the finished product screening machine 6, and the finished product screening machine 6 screens out the raw materials smaller than about 5 mm. The sand powder is also sent into the finished product classifier 7; the distribution plate 7.3 of the present embodiment is connected at an angle of 85 degrees with the classifying plate 7.4, an...

Embodiment 2

[0033] Refer to attached figure 1 with 2 , choose basalt and tailings of different particle sizes as raw materials for sand making. The raw material conveyor 2 sends the above-mentioned raw materials in the storage bin 1 to the impurity separator 3 for impurity separation, and then enters the hammer crusher 4 to pre-break the separated stone raw materials to a size range smaller than 80mm, and then conveys them through the raw material The machine 2 sends it to the rod mill sand making machine 5 for sand making, and uses the rod mill sand making machine 5 to crush the raw materials less than 80 mm to less than 25 mm, and transports them to the finished product screening machine 6, and the finished product screening machine 6 screens out The sand powder less than 5mm is sent into the finished product classifier 7; the distribution plate 7.3 of the present embodiment is connected with the classifying plate 7.4 at an angle of 70 degrees, and the air volume is 2504m 3 / h Blower ...

Embodiment 3

[0035] Refer to attached figure 1 with 2 , Granite, river pebbles and tailings of different particle sizes are selected as raw materials for sand making. The raw material conveyor 2 sends the above-mentioned raw materials in the storage bin 1 to the impurity separator 3 for impurity separation, and then enters the impact crusher 4 to pre-break the separated stone raw materials to a size range less than about 80mm, and then passes through The raw material conveyor 2 sends it to the impact sand making machine 5 for sand making, and the impact sand making machine 5 crushes the raw materials smaller than about 80 mm to about 25 mm, and transports them to the finished product screening machine 6, and the finished product screening machine 6 Sieve out the sand powder less than about 5mm and send it into the finished product classifier 7; the distribution plate 7.3 of this embodiment is connected with the classifying plate 7.4 at an angle of 90 degrees, and the air volume is 2100m ...

Abstract

The invention discloses a dry method mechanism building aggregate grading method and device. The method includes: separating the impurity for the ore raw material containing different atones, precrushing, anhydrous fine crushing, sieving, grading the finished product, and at last respectively recycling the aggregate finished products with different levels. The device of the invention comprises a impurity separator, a prebreaker, a fine crusher, a finished product sieving machine, a finished product sizing machine. The method and device of the invention are adopted, the whole production flow has no water, the crushing, the sieving and the grading are executed in the anhydrous condition, the used raw material is very wide, various ore raw materials can be adopted, 0 to 25 mm of products comprising stone dust, mechanical sand and broken stone are produced in the whole anhydrous mechanism, thus having saved resource, high productivity effect, low cost, no environment pollution and variousfinished product levels.

Description

technical field [0001] The invention relates to the technical field of building sand making, in particular to a method for grading building aggregates in a dry process, that is, building sand, and sand making grading equipment. Background technique [0002] With the rapid development of my country's construction field, the amount of sand used in construction is also increasing. Traditional sand and gravel production usually uses natural sand and gravel washing. The raw materials are taken from the land, and the production process uses water washing to make sand. Such as Chinese patent 200620101331.5, the advantage of this patent is that it has the functions of crushing, screening, and sand washing; what it wants to solve is that the sand making machine system commonly used in China is composed of a single machine such as a crusher, a screening machine, and a sand washing machine. Install them separately, and use a belt conveyor to connect the components according to the sand...
