Abstract
The utility model discloses a hammer mill, comprising a base, wherein a lower housing and an upper housing are arranged on the base; the lower housing is located under the upper housing; the upper housing and the lower housing are matched to form a milling chamber; a feeding hole is formed in the upper housing; a discharge hole is formed at the bottom of the lower housing; a main shaft driven by a motor is arranged in the milling chamber in the upper housing and the lower housing; a rotor is sleeved to the main shaft; a plurality of rotating pin shafts are arranged on the rotor; and a plurality of hammer pieces capable of rotating around the rotating pin shafts are sleeved to the rotating pin shafts. The hammer mill provided by the utility model is characterized in that materials are milled by virtue of high speed impact generated by the hammer pieces while rotating along the rotor and also by means of materials pressing the hammer pieces at a high speed, the impact force is great and the material milling effect is good; and the hammer mill provided by the utility model is simple in structure and convenient to use.
Description
Technical field
The utility model relates to the reducing mechanism for the grain product processing usefulness of bulk material and hard material, is specifically related to a kind of beater grinder.
Background technology
Pulverizer is that application machine power is carried out comminution process to solid material, makes it to become the device of fritter, particulate or powder.Traditional pulverizer has.Wherein, hammer mill mainly comprises rotor, and rotor is arranged with hammer leaf outward, and the motor drives rotor is rotation at a high speed in crusher chamber.Material feeds in the machine from the top material inlet, is subjected to the strike, impact, shearing, abrasive action of the hammer leaf of high-speed motion and pulverizes.And existing beater grinder structure is comparatively complicated, and crushing effect is relatively poor.
Summary of the invention
The purpose of this utility model is: at the deficiencies in the prior art, the utility model provides a kind of beater grinder simple in structure, easy to use.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of beater grinder, comprise base, base is provided with lower casing and upper casing, described lower casing is positioned at described upper casing below, described upper casing and lower casing cooperate the formation crushing chamber, described upper casing is provided with charging aperture, the below of lower casing is discharging opening, be provided with by motor-driven main shaft in the crushing chamber in described upper casing and the lower casing, be arranged with rotor on the described main shaft, described rotor is provided with some axles of shipping and reselling on another market, and the described outer shaft sleeve of shipping and reselling on another market is provided with the hammer leaf that some bearing pins that rotate rotate.
As preferably, the discharging opening place of described lower casing is provided with mesh screen.After adopting above-mentioned preferred version, the difference of the size of particle that can be as required, the particle that the difference screening that utilizes mesh to count size needs, excessive particle is left on the mesh screen.
As preferably, described rotor outside weld is connected to some bearing pin stators, and plane, described bearing pin stator place arranges with the main shaft axial location is vertical, and the described axle of shipping and reselling on another market is arranged on the bearing pin stator.After adopting above-mentioned preferred version, the bearing pin stator provides the installation site for changeing Xiao Zhou, and the bearing pin stator adopts the mode of welding to be fixed on the rotor simultaneously, and is fixing more firm.
As preferably, be arranged with some spacers on the described axle of shipping and reselling on another market, described spacer is distributed between hammer leaf and the hammer leaf.After adopting above-mentioned preferred version, avoid the hammer leaf that is enclosed within on the same axle of shipping and reselling on another market close mutually, make hammer leaf comminuting matter better.
As preferably, described rotor and main shaft fixedly mount by the mode of spline.After adopting above-mentioned preferred version, rotor and main shaft easier for installation.
As preferably, the two ends of described main shaft pass outside upper casing and the lower casing, and are provided with bearing block and cartridge housing outside main shaft passes upper casing and lower casing, are provided with bearing in described bearing block and the cartridge housing, and described bearing holder (housing, cover) is located at outside the main shaft.After adopting above-mentioned preferred version, pulverizer operation ground is more steady.
High speed impact and material itself that beater grinder of the present utility model utilizes hammer leaf to produce when rotating along with rotor make material pulverize with the high speed stamping hammer leaf, impulsive force is big, the material good crushing effect, and beater grinder of the present utility model is simple in structure, easy to use.
