Description

Processing equipment for multi-stage crushing and screening

technical field

The utility model relates to the field of machinery, in particular to a processing equipment for multistage crushing and screening.

Background technique

The pulverizer is a common equipment for crushing materials. Its working principle is to insert a shaft into the cylindrical pulverizer casing, distribute the blades evenly in the axial direction of the shaft, and use the motor to drive the shaft to rotate to complete the pulverization. The material in the machine is crushed. However, due to the limitation of the structure of the casing, the material will move irregularly in the cavity of the casing during the crushing process, so that the blade cannot crush the material in time, resulting in uneven crushing of the material, and with the continuous deepening of the market , the requirements for product diversification are getting higher and higher, and the requirements for equipment for producing products are also getting higher and higher. For material crushing, it is expected to obtain products with different particle sizes after crushing to meet different uses.

Utility model content

The purpose of this utility model is to provide a multi-stage crushing and screening processing equipment, which can make the material be fully crushed and screened at the same time, and the iron impurities in the material can be screened and removed before the crushing process, so as to avoid the impact of iron impurities on the mill. Roll damage and impact, while improving the crushing process efficiency.

The multi-stage crushing and screening processing equipment of the utility model includes a crushing bin and two rolling rollers arranged in the manner of opposite rollers arranged at the feeding port of the crushing bin, and facing the rolling rollers with the axis perpendicular to the horizontal direction. The spiral blade connected to the rotating shaft arranged below, the blade spirally extends from the upper part of the rotating shaft to the lower part of the rotating shaft around the rotating shaft to form a helical structure spaced apart from each other, and the helical radius of the upper part of the rotating shaft is less than The lower spiral radius, side baffles are arranged longitudinally around the spiral blade, a partition is horizontally arranged between the spiral blade and the rolling roller, and a secondary feeding port is arranged on the partition;

Further, a vibrating sieve is arranged in an inclined manner with a certain acute angle to the horizontal direction under the helical blade, and the vibrating sieve is circumferentially distributed in the crushing bin with the rotation axis of the helical blade as the center;

Further, the vibrating screen is set in an inclined manner with an angle of 30° with the horizontal direction;

Further, the side wall of the feeding port is provided with magnets.

Further, the rotating shaft is set through the bottom of the crushing bin;

Further, a slide rail is provided at the bottom of the crushing bin, and a wheel shaft cooperating with the slide rail is provided on the storage tank.

Beneficial effects of the present utility model: the multi-stage crushing and screening processing equipment of the present utility model, through the double crushing action of the rolling roller and the spiral blade, can make the material be fully crushed, and the multi-vibrating screen installed at an inclination can also The materials that are not fully crushed can be quickly screened out to achieve the purpose of fine selection, and can be smoothly discharged from the crushing cylinder. The structure is simple and easy to manufacture.
