Description

A hammer mill

technical field

The utility model relates to a crushing device used for grain product processing of bulk material and hard material, in particular to a hammer mill. the

Background technique

A pulverizer is a device that uses mechanical force to crush solid materials into small pieces, fine particles or powder. Traditional shredders have. Among them, the hammer crusher mainly includes a rotor, the rotor jacket is equipped with hammer blades, and the motor drives the rotor to rotate at high speed in the crushing chamber. The material is fed into the machine from the upper feeding port, and is pulverized by the impact, impact, shearing and grinding of the high-speed moving hammer. However, the existing hammer mill has a relatively complicated structure and poor crushing effect. the

Contents of the invention

The purpose of the utility model is to provide a hammer pulverizer with simple structure and convenient use for the deficiencies of the prior art. the

In order to achieve the above object, the utility model has adopted the following technical solutions:

A hammer mill, comprising a base on which a lower casing and an upper casing are arranged, the lower casing is located below the upper casing, and the upper casing and the lower casing cooperate to form a pulverized Cavity, the upper casing is provided with a feed inlet, and the bottom of the lower casing is a discharge outlet. The crushing chambers in the upper casing and the lower casing are provided with a main shaft driven by a motor. A rotor is sheathed on the main shaft of the rotor, and a plurality of revolving pin shafts are arranged on the rotor, and a plurality of hammer blades that can rotate around the revolving pin shafts are provided outside the revolving pin shaft.

As a preference, a mesh screen is provided at the outlet of the lower casing. After adopting the above-mentioned preferred scheme, according to the difference in the size of the required particles, the required particles can be screened by using the mesh size of the mesh screen, and the oversized particles are left on the mesh screen. the

As a preference, several pin fixing pieces are welded on the outside of the rotor, the plane where the pin fixing pieces are located is arranged perpendicular to the axial position of the main shaft, and the revolving pin shaft is arranged on the pin fixing pieces. After adopting the above-mentioned preferred solution, the pin shaft fixing piece provides an installation position for the small rotor, and at the same time, the pin shaft fixing piece is fixed on the rotor by welding, which makes the fixing more firm. the

As a preference, several spacers are sheathed on the rotating pin shaft, and the spacers are distributed between the hammer pieces. After adopting the above-mentioned preferred solution, the hammer blades sleeved on the same revolving pin shaft are prevented from approaching each other, so that the hammer blades can crush materials better. the

Preferably, the rotor and the main shaft are fixedly installed by means of splines. After adopting the above preferred solution, the installation of the rotor and the main shaft is more convenient. the

As a preference, the two ends of the main shaft pass through the upper casing and the lower casing, and a bearing seat and a bearing shell are provided outside the main shaft passing through the upper casing and the lower casing, and the bearing seat and the bearing shell Bearings are arranged inside, and the bearing sleeve is arranged outside the main shaft. After adopting the above preferred scheme, the pulverizer runs more smoothly. the

The hammer mill of the utility model utilizes the high-speed impact produced by the hammer when the rotor rotates and the material itself punches the hammer at a high speed to crush the material. The impact force is large and the material crushing effect is good. The pulverizer is simple in structure and easy to use. the
