Abstract

The invention discloses a multi-stage crushing and grinding output device for building aggregate, which comprises a base, a pushing material cylinder, a grinding cylinder, a secondary crushing cylinder and a primary crushing cylinder. The upper end of the base is fixed with a pushing material cylinder, and the pushing material The upper end of the cylinder is welded in sequence from bottom to top with a grinding cylinder, a secondary crushing cylinder, a primary crushing cylinder and a feeding hopper. The cavity is connected, and the left crushing roller and the right crushing roller are installed in the primary crushing cavity; the bottom of the primary crushing cylinder is provided with a primary crushing port, and the bottom of the primary crushing port is connected to the crushing and screening hopper, which has a simple structure and is convenient for feeding. , realize the primary crushing of building aggregates, and obtain evenly textured building aggregate crushed particles with good grinding effect, which are discharged from the discharge port under the push of the pusher screw, and realize the step-by-step crushing, grinding and output operations of building aggregates. Improve the efficiency and effect of building aggregate crushing and grinding.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a multi-stage crushing and grinding output device for building aggregate. Background technique [0002] Construction aggregate is a granular loose material that acts as a skeleton or filling in concrete. Aggregate, as the main raw material in concrete, plays a vital role in construction. Aggregate is divided into different types according to different particle sizes. : Aggregate with a particle size ≥ 4.75mm is called coarse aggregate. There are often two types of gravel and pebbles. Crushed stone is made by mechanically crushing and screening natural rocks; the particle size below 4.75mm is called It is fine aggregate, commonly known as sand. Sand is divided into natural sand and artificial sand according to the source of production. The amount of natural sand is limited and it is difficult to salvage, and the texture of large-grained aggregates such as stones is ...
