Vertical combined crushing and grinding machine

Abstract

The invention provides a vertical combined crushing and grinding machine. The vertical combined crushing and grinding machine comprises an integral support, a grinding cavity seat, a cylinder body, a vertical rotor body, a spiral impact plate, a discharge hopper, charge hoppers, a turnover door, a grinding cavity wall lining plate, an electromotor, a crushing mechanism and a grinding mechanism. The vertical combined crushing and grinding machine enables the material crushing and grinding processes to be realized by one machine, is compact in structure and small in occupied area, saves the process, and improves the efficiency. Materials are impacted and crushed at high speed by a hammer head on a tower-shaped hammer seat in a spiral through crushing cavity, are thrown to the turnover door, are rebounded to the hammer head on the tower-shaped hammer seat, and are crushed repeatedly in the way, so as to guarantee relatively sufficient crushing. A centrifugal rotation roller acts on a grinding cavity wall lining plate, the materials are ground and crushed to 1mm below, and the qualified materials discharged from the discharge hopper finally are uniform in granularity and high in crushing ratio. In addition, the crushing and grinding cavity of the through combined crushing and grinding machine of the design is difficult to block, is smooth in material discharge and is long in service life, and the industrial cost is reduced.

Description

technical field [0001] The invention relates to the field of crushing and grinding devices, in particular to a vertical compound crushing and grinding machine, which is used for crushing and grinding materials in the fields of coal, metallurgy, mining and construction. Background technique [0002] In the fields of coal, metallurgy, mining and construction, the crushing of bulky materials is generally carried out by crushers. At present, there are many types of common crushers, such as impact crushers, cone crushers, hammer crushers, and roller crushers. Direct crushing to less than 1m through one machine; the hammer head is easy to wear and the utilization rate is low; the crushing ratio is small; in order to achieve the particle size requirement of less than 1mm, the scheme of repeated crushing through multi-stage screening is not only large in advance investment, but also occupies a large area. In the later stage, the energy consumption is large, the maintenance cost is ...

AI Technical Summary

Problems solved by technology

At present, there are many types of common crushers, such as impact crushers, cone crushers, hammer crushers and roller crushers, etc., but these crushers have some problems, such as the crushing particle size cannot meet the requirements, and the materials cannot be crushed. Direct crushing to less than 1m through one machine; the hammer head is easy to wear and the utilization rate is low; the crushing ratio is small; in order to meet the particle size requirement of less than 1mm, the plan of repeated crushing through multi-stage screening not only requires a large initial investment and occupies a large area, but also Large energy consumption, high maintenance cost and low efficiency in the later stage
