Problems solved by technology

[0010] The already known equipment is not without flaws, although used and respected; in particular, the intermittent grinding requires a great deal of downtime to load the stock and discharge the slurry; these steps have always been done by hand

Embodiment Construction

[0030] As can be seen from Figures 1 and 2, a discontinuous mill 1 is used to process coarse-grained raw materials to obtain a slurry with a certain particle size.

[0031] The discontinuous mill 1 comprises a cylindrical drum 2 having a horizontal axis, and the drum also comprises a housing 3, a top base 4 and a bottom base 5, the top base 4 and the bottom base 5 The housing 3 is closed on both sides and defines an internal cavity 20 into which grinding bodies of suitable size are introduced.

[0032] A protruding shaft 6 arranged coaxially with the housing 3 is connected to the bottom base plate 5 (see Figure 2), while a hollow cylindrical sleeve 7 also protrudes from the housing 3 and is mounted coaxially with the housing 3 , which is suitable as an opening to communicate the internal cavity 20 with the outside world, and is connected with the top bottom plate 4 .

[0033] The protruding shaft 6 and the hollow cylindrical sleeve 7 are connected together via bearings 8 with...

Abstract

A grinding mill (1) having a cylindrical drum (2) with horizontal axis suitable for rotating about said axis both in an operative direction (A) and in an opposite direction (B), said cylindrical drum being equipped with an outer shell (3) closed by a top base plate (4) and by a bottom base plate (5) and with a system for emptying the cylindrical drum (2) itself that comprises at least one outlet mouth (14) formed in the outer shell (3), and a discharge pipe (16) that, being equipped with a first end (50) associated with said at least one outlet mouth (14) and a second end (51) open to the outside, surrounds the outer shell (3) in a direction matching the operating rotation direction (A) of the cylindrical drum (2).

Description

technical field [0001] The present invention relates to a discontinuous grinder, in particular, but not limited to, a discontinuous grinder suitable for use in the field of ceramics for the preparation of clay dough. Background technique [0002] In the field of ceramics, through wet crushing of raw materials and adding special additives during the crushing process, until a homogeneous slurry is obtained, and the suspended powder in the slurry should meet the required particle size determination requirements, this method It is a known technology to make pottery clay groups. [0003] According to the prior art, the crushing process consists of three consecutive steps and starts with a rolling step and ends with a refining step. [0004] In the field of ceramics, mills for this kind of operation are known and widely used, in which the crushing is done by impact, in general by the interaction between grinding bodies, generally spherical in shape . [0005] The grinding bodie...
