Description

A vertical dry mill system

technical field

The utility model relates to a grinding system, in particular to a vertical dry grinding machine system for crushing limestone.

Background technique

Limestone is widely distributed and abundant in my country, and is a valuable resource with a wide range of uses. It is usually used as a building material and is also an important raw material for many industries. It can be used for the production of Portland cement and the production of high-grade paper-making coating-grade heavy calcium carbonate products. Used as a filler in the production process of plastics and coatings. Production of foundry sand for machinery manufacturing. Production of desulfurization absorbents. Used in the production of active lime and passivated lime. Limestone is calcined to produce active lime, and after processing, passivated lime can be produced. The commonly used processing technology of limestone is to use a special mill for mechanical crushing to make it into powder. After the limestone is directly crushed, heavy calcium carbonate can be obtained. According to the difference in crushing fineness, it is used in different industrial sectors in industry.

At present, the limestone mills launched by various domestic manufacturers are developed on the basis of the design process of traditional Raymond mills. They are specially suitable for the deep processing of limestone. They are called Raymond mills in the industry. This series of mills The machine adopts a relatively mature milling process design, which can be well applied to the processing and production of limestone. The basic working principle of this type of pulverizer is: after the crusher breaks the bulky raw materials to the required feed size, the material is transported to the storage bin by the bucket elevator, and then evenly distributed by the electromagnetic vibrating feeder. The material is sent to the grinding chamber of the main engine, and the material is scooped up and thrown between the roller rings of the grinding roller during the co-rotation process of the blade and the grinding roller to form a pad layer, and the material is ground between the grinding roller and the grinding ring, thereby achieving Milling purposes. The powder after grinding is brought to the analyzer by the air flow of the fan to select the powder, and the fine powder that meets the fineness requirements enters the large cyclone collector through the pipeline with the air flow, and is separated and collected, and then discharged through the unloader to become the finished powder. The air flow is sucked into the blower by the return air pipe at the upper end of the large cyclone collector. The unqualified powder is thrown to the outer wall by the blades and separated from the air flow, and the coarse powder falls into the grinding chamber due to its own gravity for regrinding. The entire airflow system of this machine is a closed cycle, and it circulates under positive and negative pressure conditions.
