Description

Novel mill structure

Technical Field

The utility model belongs to the technical field of mining machinery, concretely relates to novel mill structure.

Background

The mill is an important fine grinding device in modern industry, is one of the most common important devices in a grinding system, and is widely used for grinding cement and other materials in building materials, metallurgy, mineral separation, electric power and chemical industry. The main components of the mill are a cylinder, a feeding part, a discharging part, a transmission part and the like. The material passes through feed arrangement and gets into inside the mill barrel, and when the barrel rotated, grinding medium and material along with the barrel gyration and promoted certain height under the effect of frictional force and centrifugal force, then fall or cascade down according to certain linear velocity, and the material receives the striking of whereabouts steel ball and bold material to with the help of between steel ball and steel ball, between steel ball and mill welt, between material and the material and between material and steel ball and welt additional crushing and the mill effect of peeling and is smashed. The materials with gradually reduced particle sizes slowly flow to the discharge end under the action of material pressure, are ground to very fine particle sizes when reaching the discharge end, and are screened by the discharge grate plate, fine powder with qualified particle sizes is forcibly discharged out of the mill by the discharge grate plate and enters the next process.

At present, a barrel lining plate and grinding balls are main working components in normal operation of the mill, and for the whole mill, the whole length of the mill is long, the material particles close to a feeding end are large, the material particles far away from the feeding end are small, the lining plate close to the feeding end is seriously worn, the surface wear of the lining plate far away from the feeding end is relatively light, and the purpose of synchronous wear of the front lining plate and the rear lining plate cannot be achieved.

Disclosure of Invention

The utility model discloses a solve above-mentioned technical problem, provide a novel mill structure, its project organization is reasonable, convenient to use, can be more shallow with the groove depth design of being close to mill feed end welt bottom, the welt bottom groove depth design of keeping away from mill feed end is darker, under the unchangeable prerequisite of the whole appearance of welt, the welt that is close to the feed end can bear great wearing and tearing volume for the welt at both ends can obtain make full use of around the mill, improves the rate of utilization of welt.

The utility model adopts the technical proposal that: the utility model provides a novel mill structure, includes the barrel and installs a plurality of welts at the barrel inner wall position, and a plurality of welts splice each other at the barrel inner wall, and the welt includes the welt body, and the lower surface of welt body is circular-arc structure, is equipped with the recess sunken to the welt body is inside at the bottom surface intermediate position of welt body, and the welt bottom groove depth degree that is close to barrel feed end position is less than the welt bottom groove depth degree of keeping away from barrel feed end position.

The upper surface of welt body one side position an organic whole is connected with the bellied promotion strip that makes progress, and the length of promoting the strip equals with the length of welt body.

The upper surface an organic whole of welt body is connected with the bellied welt mount pad that makes progress, and welt body bottom groove position is equipped with and corresponds with welt mount pad position and bellied circular boss, has seted up the bolt mounting hole on the welt mount pad.

The circular boss is coplanar with the bottom surface of the lining plate body.

The quantity of welt mount pad is two, and a side and the promotion strip body coupling of welt mount pad install on the position between two welt mount pads and be used for fastening the enhancement ear seat of strengthening with promotion strip and welt body.

And the inner wall positions of the front end and the rear end of the cylinder are respectively and fixedly provided with a cylinder feeding plate and a discharging plate.

When the novel mill structure is used, a bolt is penetrated through a bolt mounting hole on a liner plate mounting seat, a liner plate body is fixed on the inner wall of a cylinder body of the mill by the bolt, when the novel mill structure works, materials enter the cylinder body from the feed end of the cylinder body, the cylinder body is lifted to a certain height under the action of a lifting strip and centrifugal force after rotating, then the materials are thrown down according to a certain linear velocity, and in the throwing process, the materials collide with steel balls, other materials and the liner plates to achieve the purpose of grinding and grinding, because the material particles close to the feed end position of the cylinder body are large, the impact force on the liner plates is large when the liner plates fall, the abrasion speed of the liner plates close to the feed end position of the cylinder body is high in unit time, in order to prevent the liner plates at the front end in the cylinder body from being completely abraded and the liner plates at the rear end from being, the design depth of the groove at the bottom of the lining plate body close to the feeding end is shallow, and the design depth of the groove at the bottom of the lining plate body far away from the feeding end is deep, so that the service life of the front-end lining plate is prolonged, and the purpose of front-back synchronous abrasion is achieved.

The lower surface of the lining plate body is of an arc-shaped structure, and a groove which is sunken towards the inside of the lining plate body is formed in the middle of the bottom surface of the lining plate body; the purpose of this is: the lining plate body with the arc-shaped structure is matched with the inner wall of the cylinder, and the groove is formed to reduce the contact area between the lining plate body and the inner wall of the cylinder when the lining plate body and the inner wall of the cylinder are installed, so that the installation precision is improved.

The depth of the groove at the bottom of the lining plate close to the feeding end of the cylinder body is smaller than the depth of the groove at the bottom of the lining plate far away from the feeding end of the cylinder body; the purpose of this is: can change the thickness change of welt body through the change of recess degree of depth, under the unchangeable prerequisite of guaranteeing welt appearance structure, reach the synchronous wearing and tearing of welt purpose around in the barrel, avoid causing the waste of material.

The utility model has the advantages that:

the utility model relates to a rational in infrastructure, convenient to use can be more shallow with the depth of groove design near mill feed end welt bottom, and the welt bottom depth of groove design of keeping away from mill feed end is darker, under the unchangeable prerequisite of the whole appearance of welt, and the welt that is close to the feed end can bear great wearing and tearing volume for the welt at both ends can obtain make full use of around the mill, improves the rate of utilization of welt.
