Description

Technical Field

[0001] The invention relates to a sand making building and a production method thereof, belonging to the technical field of sand making buildings. Background Art

[0002] The existing sand and gravel aggregate production lines on the market are mainly divided into two categories: flat production lines (crushing lines) and three-dimensional production lines (sand making buildings). Flat production lines refer to the placement of crushers, vibrating screens, powder selection equipment, dust removal equipment, etc. on the same plane. Belt conveyors are generally used for material transportation between crushers, vibrating screens, powder selection equipment, etc., which have the disadvantages of large footprint, low integration, inconvenience in environmental protection, and large overall packaging investment. The three-dimensional production line is also called a sand making building, which has a three-dimensional layout of crushers, vibrating screens, and powder selection equipment. The main building is highly integrated for overall packaging, but the building is relatively high, and the raw materials are fed by inclined belt conveyors, which occupy a large area and require a large equipment investment.

[0003] A sand-making building provided by the prior art places the crusher below the side of the vibrating screen, not directly below the vibrating screen. The layout is messy and occupies a large area. The user's overall environmental protection package needs to erect columns from the ground, which requires a large investment. The raw materials are lifted to the crusher through a variable frequency feeding belt conveyor, an inclined belt conveyor, and a first bucket elevator. The overall energy consumption of the secondary lifting of the materials is wasted. After crushing, the materials are lifted through a chute and a second bucket elevator and enter the powder selection box and the vibrating screen in turn. The qualified sand after screening is transported to the finished product warehouse. The oversized materials enter the first bucket elevator through a chute and are lifted to the crusher for cyclic crushing. The first bucket elevator and the second bucket elevator are of the same specifications and models. The feeding unit includes a feeding hopper, a variable frequency feeding belt conveyor, and an inclined belt conveyor, which occupies a large area. This solution also requires special dust removal at the transfer point between the variable frequency feeding belt conveyor and the inclined belt conveyor. The equipment process is too complicated and the investment is wasted. The powder selection box is directly connected to the dust collector. The stone powder collected during the powder selection process contains a small amount of fine sand particles. There is no device to filter and recover the fine sand in the dust, which cannot improve the purity of the stone powder, affects the quality of stone powder and finished sand, and reduces the service life of the dust collector bag.
