Abstract

A new type of rod mill, which is composed of a power unit and a cylinder. The cylinder is composed of a semi-cylindrical casing and two dropped steel plates. There is a rotating main shaft in the middle of the cylinder. The rotating main shaft is connected with the external pulley. There are two rotating scrapers welded, a number of dielectric rods are placed inside the cylinder, there is a material inlet at the top of the cylinder, and a discharge port at the bottom of the cylinder, between the two throwing steel plates and between the throwing steel plates and the The semi-cylindrical casings are connected by a rotating pin shaft, and the angle of the dropped steel plate can be adjusted by rotating the pin shaft. The utility model realizes the multiple throwing process of the material and the medium rod, which not only strengthens the impact effect of the material and the dropped steel plate, but also strengthens the grinding and crushing action between the material and the medium rod, and has high grinding efficiency and high grinding efficiency. The mining effect is good, and at the same time, the angle of the steel plate can be flexibly adjusted by turning the pin shaft, which increases the adaptability to different materials.

Description

A new type of rod mill

technical field

The invention relates to a crushing and grinding machine, in particular to a high-efficiency rod mill for multiple throwing and grinding.

Background technique

Rod mills are widely used in mineral processing plants and chemical plants. They are mainly used for grinding and crushing of materials. Steel rods or rods of other materials are used as grinding media in the grinding cylinder. Under the action of centrifugal force and friction, the material and medium rod are lifted to a certain height along with the wall of the cylinder, and then fall or roll down freely from the wall of the cylinder, mainly relying on the impact force and grinding effect of the medium rod to grind the material. The rod milled product is more uniform, and the over-grinding is lighter. However, conventional rod mills can only be dropped once in a cycle, so the impact force on materials is poor, so there are problems such as unsatisfactory grinding efficiency and poor adaptability to different materials.

Contents of the invention

Aiming at the problems existing in the background technology, the utility model provides a new type of rod mill, which realizes multiple impacts and grinding between the material and the steel plate and between the material and the medium rod through the multiple throwing process of the material and the medium rod. Cutting and other functions, thereby improving the grinding efficiency, and at the same time, the angle of the steel plate can be adjusted by turning the pin shaft, thus enhancing the adaptability to different materials.

The technical solution adopted by the utility model to solve the technical problem is: a new type of rod mill, which is composed of a power device and a cylinder body. The cylinder body consists of a semi-cylindrical casing (4) and two throwing steel plates (1) Composition, there is a rotating main shaft (2) in the middle of the cylinder, the rotating main shaft (2) is connected with the outer pulley (6), two rotating scrapers (3) are welded on the rotating main shaft, and a number of medium rods (9) are placed inside the cylinder ), there is a material inlet (5) at the top of the cylinder, and a material outlet (7) at the bottom of the cylinder, between the two throwing steel plates (1) and between the falling steel plates (1) and the semi-cylindrical The casings (4) are connected by a rotating pin shaft (8), and the angle of the dropped steel plate (1) can be adjusted by rotating the pin shaft (8).

The beneficial effect of the utility model is that in the grinding process, the material and medium rods are dropped many times, which not only strengthens the effect of the impact force in the grinding process, but also reduces the power consumption of the grinding, thereby improving the At the same time, the angle of dropping the steel plate can be changed by turning the pin shaft to increase the adaptability to the material.

Detailed ways

The embodiments of the present invention will be further described below in conjunction with the accompanying drawings: A new type of rod mill, consisting of a power unit and a cylinder, the cylinder consists of a semi-cylindrical casing (4) and two throwing steel plates (1) Composition, there is a rotating main shaft (2) in the middle of the cylinder, the rotating main shaft (2) is connected with the outer pulley (6), two rotating scrapers (3) are welded on the rotating main shaft, and a number of medium rods (9) are placed inside the cylinder ), there is a material inlet (5) at the top of the cylinder, and a material outlet (7) at the bottom of the cylinder, between the two throwing steel plates (1) and between the falling steel plates (1) and the semi-cylindrical The casings (4) are connected by a rotating pin shaft (8), and the angle of the dropped steel plate (1) can be adjusted by rotating the pin shaft (8).

Working process: The material enters the rod mill from the feeding port (5), the belt pulley (6) drives the rotating main shaft (2) to rotate, the media rod (9) installed inside the rod mill and the material under the action of centrifugal force and friction Next, as the rotating scraper (3) makes a counterclockwise circular motion along the semi-cylindrical casing (4), a certain grinding effect will occur between the materials and between the materials and the medium rod at this time. When the medium rod and the material reach the highest point of the hollow cylinder, they are thrown flat, and at the same time, because of their high kinetic energy, they can be repeatedly thrown on the dropped steel plate (1), and the final product is discharged from the discharge port (7). The material is not only impacted by the impact, but also ground and crushed by the medium rod during the multiple throwing process, which strengthens the grinding effect.
