Energy-saving and environment-friendly milling screening machine

Abstract

The invention relates to the technical field of grinding equipment, in particular to an energy-saving and environment-friendly milling screening machine. The energy-saving and environment-friendly milling screening machine comprises a material feeding portion, a barrel body and a driving device, wherein a lining plate is arranged in the barrel body, the material feeding portion is connected with the barrel body through a hollow shaft, the barrel body is connected with the driving device through a transmission shaft, a barrel opening, away from the material feeding portion, of the barrel body is in a sealed shape, a material discharging hole is formed in the barrel body, a screen is arranged outside the barrel body, surrounds the outside of the barrel body, and is arranged in a barrel shape, a screening portion is formed between the screen and the barrel body, one end of the screening portion is open, the other end of the screening portion is closed, and the closed end of the screening portion and the closed end of the barrel body are connected with each other, and are located at the same side. According to the energy-saving and environment-friendly milling screening machine disclosed by the invention, milling and screening integrated production is realized without arranging a plurality of sets of equipment; energy consumption of equipment for screening and conveying can be reduced; the accumulation of materials can be effectively avoided as a strong exhaust hole is formed, and therefore the yield and production efficiency are increased, finer grinding phenomena can be reduced, and the pick-up rate of finished products is increased; moreover, the milling and screening in both dry and wet manners can be realized, so that production adaptability is enhanced, and the wet-type operation can also solve the problem of flying dust.

Description

technical field [0001] The invention relates to the field of grinding equipment, in particular to an energy-saving and environment-friendly grinding and screening machine. Background technique [0002] The grinding equipment currently used for crushing materials mainly includes rod mills and ball mills. Both are widely used in metal and non-metal mines, water conservancy and building materials departments to grind various ores or rocks. The size of the ground material is uneven, if it needs to be subdivided, it still needs to be screened by a screening device. When it is necessary to grind and crush dry and wet materials, different grinding equipment needs to be equipped. When multiple equipments are running at the same time, the energy consumption is high, and the maintenance cost is high, and more operators are required. It is difficult to achieve multiple functions of one machine, which increases equipment and labor. Input costs. When the amount of material added is la...

Problems solved by technology

When it is necessary to grind and crush dry and wet materials, different grinding equipment needs to be equipped. When multiple equipments are running at the same time, the energy consumption is high, and the maintenance cost is high, and more operators are required. It is difficult to achieve multiple functions of one machine, which increases equipment and labor. Input costs

When the amount of material added is large, the ground and broken materials accumulate near the discharge port, and it is difficult to discharge after accumulation to a certain extent. Start and stop, it is easy to cause damage to components and affect the life of the whole machine
