Machine-made sand screening and treatment integrated device for construction

Abstract

The invention relates to a machine-made sand screening and treatment integrated device for construction. The machine-made sand screening and treatment integrated device comprises a first screening component, a mud water precipitation component, a hammering component, a grinding component and a second screening component. By specifically arranging all the components, efficient separation of stone blocks, stone particles and floating soil is achieved firstly, efficient fine crushing of the stone blocks in the same size is achieved in the mode that the separated stone blocks are hammered and ground, the separated stone particles and floating soil form gravel and mud in the mode of back flushing of a water body to be separated, and thus uniform machine-made sand particles are finely produced. The water body is reused after the mud is precipitated, and thus the utilization rate of the water body is greatly increased.

Description

technical field [0001] The invention relates to the field of preparation of building materials, in particular to an integrated device for screening and processing machine-made sand for construction. Background technique [0002] A large amount of crushed stones are produced in the process of stone mining and crushing. These crushed stones are very good raw materials for machine-made sand. The machine-made sand prepared from processed crushed stones has very high hardness and strength. However, in the process of mining and crushing, a large amount of floating soil will be mixed into the crushed stone, and if these floating soil enters the use of machine-made sand, it will greatly reduce the strength of the machine-made sand product, thereby affecting the quality of the machine-made sand. The method of manual screening and manual flushing is used for separation, but firstly, the manual processing method consumes a lot of labor costs, and secondly, the manual screening method w...

Problems solved by technology

However, in the process of mining and crushing, a large amount of floating soil will be mixed into the crushed stone, and if these floating soil enters the use of machine-made sand, it will greatly reduce the strength of the machine-made sand product, thereby affecting the quality of the machine-made sand. The method of manual screening and manual flushing is used for separation, but firstly, the manual processing method consumes a lot of labor costs, and secondly, the manual screening method will also remove a large number of stone particles. It also causes a lot of waste of water

At the same time, when the raw materials are further crushed, the current crushing machinery is not specially designed to crush crushed stones of this size. Using a general-purpose crushing device not only cannot guarantee the crushing particle size, but also wastes part of the crushing power of the equipment, thereby improving Hidden costs of machine-made sand raw material processing
