Screening and crushing all-in-one machine

Abstract

The invention discloses a screening and crushing all-in-one machine, which comprises a stander, wherein two vertical shaft crushers are arranged on the stander; a winnowing type screening machine is arranged above the two vertical shaft crushers and comprises a material screening hollow cavity; a mixture material inlet is formed above the material screening hollow cavity; an air inlet and an air outlet are formed on the left side and the right side of the material screening hollow cavity; and a coarse material outlet and a fine material outlet are formed below the material screening hollow cavity respectively and respectively connected with material inlets of the two vertical shaft crushers. Materials with different particle sizes are influenced by wind power and blown to different material outlet positions, so that the aim of screening materials is achieved; and the vertical shaft crushers with different frequencies and different rotating speeds are respectively connected to the coarse material outlet and the thin material outlet, so that the materials with different particle sizes and different characteristics enter different crushing cavities, and different crushing effects are achieved.

Description

technical field [0001] The invention relates to a screening and crushing integrated machine, which belongs to the technical field of material screening and crushing equipment. Background technique [0002] Screening machines and vertical shaft crushers are common equipment in industrial production, among which [0003] The screening machine is a device that divides materials into different particle sizes. The existing screening machine uses the relative movement between the bulk material and the screen surface to make some particles pass through the screen holes, and divides sand, gravel, crushed stone and other materials according to particle size. Different levels of vibrating screening machinery and equipment. The particle level of sieving depends on the pore size of the sieve surface. This type of screening machine is widely used in various industries, but there are the following problems in the process of use: [0004] 1. Its power source is a vibrating motor fixed o...

AI Technical Summary

Problems solved by technology

[0004] 1. Its power source is a vibrating motor fixed on the machine body, which distinguishes the materials on the screen surface through vibration, which has the problems of high energy consumption and high noise;

[0005] 2. The existing screening machine has complex structure, heavy weight and high manufacturing cost;

[0006] 3. The structure of the existing sieving machine is to vibrate with a motor and screen the material with a screen. The screen wears quickly, and the screen needs to be replaced frequently, which is time-consuming and labor-intensive, which will further increase the cost of use.

However, the existing vertical shaft crusher has only one crushing chamber, one main shaft, and one rotor, and there is only one kind of linear velocity and frequency of crushed materials, so that all materials can only be completed in one crushing chamber, and the vertical shaft crusher cannot Working at the best speed and frequency affects the crushing effect and service life of the vertical shaft crusher
