Detailed Description

In order to explain the technical content, the objects and the effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.

Referring to fig. 1 to 3, a horizontal sand mill of the present invention includes a frame, a driving motor, a cylinder, an end cover and a main shaft; the driving motor is arranged on the rack and is arranged corresponding to one end of the long barrel, a boss for sealing the opening at one end of the long barrel is formed on a shell of the driving motor, and the end cover is arranged at the opening at the other end of the long barrel;

From the above description, the beneficial effects of the present invention are:

As can be seen from the above description, the grinding media inside the barrel can be increased by the grinding media addition port.

As can be seen from the above description, with the above structure, grinding at a certain ambient temperature is realized, and the grinding effect is improved.

Can know from above-mentioned description, can directly perceivedly know the intraoral pressure condition of pan feeding through the manometer, avoid unusual emergence.

Referring to fig. 1 to fig. 3, a first embodiment of the present invention is:

the utility model relates to a horizontal sand mill, which comprises a frame 1, a driving motor, a cylinder 2, an end cover 3 and a main shaft 4; in this embodiment, the cylinder is a hollow cylinder, and the radius of the cylinder is 35cm and the length is 120 cm.
