Powder selecting machine for processing cement

Abstract

The invention discloses a powder selecting machine for processing cement. The powder selecting machine comprises auxiliary wind blades, main wind blades, a feed opening, a main shaft, a decelerator, an electric motor, a material sprinkling disk, a casing, a support frame, a hot air inlet, wind return blades, a discharge opening, a coarse powder outlet and an air outlet, wherein the support frame is arranged on the side wall of the casing, and the electric motor and the decelerator are mounted at the top end of the support frame; the decelerator is connected with the main shaft perpendicularly arranged in the casing, and the auxiliary wind blades are mounted at the bottom end of the main shaft; the main wind blades are arranged at the top ends of the auxiliary wind blades, and the main wind blades are communicated with the feed opening formed in the top end of the casing; the wind return blades are arranged at the bottom ends of the auxiliary wind blades, and the bottom ends of the wind return blades are communicated with the coarse powder outlet; the air outlet and the hot air inlet are respectively formed in the left end and the right end of the coarse powder outlet, and the air outlet and the hot air inlet are communicated with the casing; the discharge opening is formed in the bottom end of the casing. The powder selecting machine for processing the cement is free from overflow of dust, is environment-friendly, is efficient, is low in consumption, is simple, convenient and rapid ito regulate and is good in powder selection effect.

Description

technical field [0001] The invention relates to the technical field of cement processing, in particular to a cement processing powder separator. Background technique [0002] With the development of society, the demand for cement is increasing. At the same time, the requirements for cement production equipment are also getting higher and higher. The particle size device, the system configuration of this product is simple, the cost is low, and it can greatly increase the output of the mill. Its internal structure is reasonable and the powder selection effect is remarkable. It is the first choice product to improve the product quality of the grinding system after the implementation of the new cement standard. It guides the new trend of technological innovation of the powder separator. According to the fineness or specific surface area of ​​the product, the qualified product and the unqualified coarse powder are separated and collected, and the unqualified coarse powde...

Problems solved by technology

Its internal structure is reasonable and the powder selection effect is remarkable. It is the first choice product to improve the product quality of the grinding system after the implementation of the new cement standard. It guides the new trend of technological innovation of the powder separator. According to the fineness or specific surface area of ​​the product, the qualified product and the unqualified coarse powder are separated and collected, and the unqualified coarse powder is sent back to the ball mill for regrinding. The gas-solid two-phase flow causes the dust-laden airflow to rotate, and the coarse powder obtains a large inertial centrifugal force, which also produces a large segregation radial movement speed, and thus realizes the separation of coarse and fine powder. and fine powder are collected separately. There are many deficiencies in the current powder separator. For example, there are too many rotating parts inside the ordinary powder separator, which increases the damage of the machine during use. There are many wearing parts inside and the service life is long. Short, therefore, a cement processing powder separator is proposed to solve the above problems
