Pan mill for solid material generally includes milling container, and this milling container is limited with room, chamber of milling. Milling container can form rotation in the known pan mill of prior art, or position is supported fixingly in other known pan mills.

In order to each pulverizes operation, room, chamber has ball of milling milling, this ball such as rotating or being arranged on moving for pulverizing the agitator of solid material in room, chamber of milling by room, chamber of milling of milling. Being incorporated in room, chamber of milling in order to ball of can each being milled and derive from room, chamber of milling, each milling container all has closeable hole.

Pulverizing in operation process, ball of milling can not leak out from each milling container from each room, chamber or say of milling. To this, by stopper lipostomous.

Because solid material can have very little granularity pulverizing in operation process, and known ball of milling has very little diameter, so each stopper is connected with sealing element usually, mills ball to prevent or say that solid components is attached between stopper and shell of tank. Also the attachment preventing to have the ball of milling of mill ball and the damage of wear phenomenon with this kind of sealing element is needed. Each stopper is held by known sealing element form fit.

Practice is it has proven convenient that the form fit connection between each sealing element and stopper can not get rid of solid components cmpletely or the accident of the outer side of ball with stopper of milling contacts. If occurring milling body and/or solid components to be attached on stopper, it would be possible that stopper can be made to be clipped in hole and no longer can take out from hole.

Summary of the invention

Therefore, it is an object of the present a kind of milling container, this milling container has the sealing effect to stopper through improving.

Above-mentioned purpose is achieved by a kind of milling container, and this milling container comprises the feature in claim 1. Other favourable design is described by dependent claims.

Milling container according to the present invention is used for pan mill and therefore, it is possible to is configured to ball mill or says the integral part of agitating ball mill. Such as, milling container can have cylindrical shape.

Milling container also comprises: shell of tank, and this shell of tank limits room, chamber of milling; At least one is through the hole of shell of tank, and this hole is provided to the entrance of room, chamber of milling; In milling container and the stopper of lipostomous is remained on removedly with at least one. By this hole or say by this entrance, element of milling, such as mill ball or like can be introduced in milling container or say in room, chamber of milling and from milling container or say in room, chamber of milling and take out.

When pan mill operates, hole is closed, thus prevents solid material and/or element of milling overflows from room, chamber of milling.

In addition, be furnished with between shell of tank and stopper at least one can the sealing unit of elastic deformation, to forbid solid components and/or element of milling is attached between stopper and shell of tank. Sealing unit can with stopper and with shell of tank formed surface contact.

Specify according to the present invention, sealing unit is configured with sealing section that is that be an angle relative to the outer side of stopper or that says direction, room, the chamber inclination and court mills relative to the longitudinal center line of stopper be an angle at least in part, sealing section loaded by power and with the outer side of stopper formation surface contact.
