Description

Efficient mill

The present invention relates to a kind of cylindrical shape grater, be used for industry such as building materials, metallurgy, generating, chemical industry, material is carried out grinding, be particularly useful for material is carried out fine-grinding.

Normal mill the sizing aggregation phenomenon occurs after being ground to certain fineness, be difficult to satisfy above-mentioned industry especially cement industry to the requirement of fine-grinding, in order to address this problem, people have developed Kang Xindan mill and CN8510678 pulverizer for fine powder, and the latter's principal character is to be provided with a kind of material ball separating device of being made up of overflow type partition panel, Xiao Cang, overflow type grate plate, double-deck arc bolter and blind plate between two storehouses; A kind of material of being made up of forward swing angle liner plate and little grate plate has been installed in exit, tail storehouse has been forged separator; And use special grinding body gradation.This invention goes a step further before making the Super-fine grinder technology; but still there are some defectives; double-deck arc bolter and aperture grate plate are made difficulty; easy to wear, easy obstruction, difficult maintenance; the problem that still has the path abrasive body to run off; make abrasive body cost up and downtime long, reduced running rate, fineness is also produced.

The objective of the invention is to disclose a kind of energy and grind the material of higher fineness, low, the easy manufacturing of power consumption is installed, and parts are not fragile, do not block the grinding machine of the little abrasive body of not overflowing.

A kind of efficient mill has rotary barrel and abrasive body; Cylindrical shell divides preceding, tail two storehouses, and feed end and discharge end arranged, it is characterized in that being equipped with in the preceding storehouse ladder classifying lining board, be provided with isolation, the separator that constitutes by overflow partition panel, lifting blade, refeed line, cone and blind plate between preceding tail two storehouses, the inclination material blocking ring is housed in the tail storehouse, is provided with by overflow blind plate, lifting blade, cone in exit, tail storehouse, returns and forge the material forging that pipe, positive and negative spiral discharging tube, screen cloth constitute and isolate materials device.

The present invention separates coarse fodder and the fines that contains abrasive body with refeed line with lifting blade, do not establish double-deck arc bolter and comb hole, little comb hole, the processing and manufacturing installation and maintenance are convenient, and resistance is little, are difficult for stopping up, save energy consumption, increased running rate, the storehouse grinding body gradation changes grinding fineness before and after can regulating easily, improves grinding fineness, the abrasive body in exit borrows lifting blade, return and forge pipe and positive backpitch and return the tail storehouse and do not run off, and saves the cost of abrasive body and examines back man-hour of abrasive body.The present invention can not only grind high thin product, also can increase output to general fineness product, reduces power consumption, and simple in structure, and some parts identical with conventional mill are arranged again, is suitable for modernizing and expanding the existing factory.

Describe in detail below by the example structure accompanying drawing:

Description of drawings:

Fig. 1 is the structural representation of efficient mill;

Fig. 2 is a ladder classifying lining board member oblique view;

Fig. 3 is the oblique view of inclination material blocking ring member;

Fig. 4 is the left view of isolation, separator;

Fig. 5 forges the left view of isolating materials device for material.

The cylindrical shell 1 inner quilt of embodiment is isolated separator and is divided into preceding storehouse 15 and tail storehouse 16, ladder classification lining body 2 is installed in the preceding storehouse, its inner surface is Archimedes's logatithmic spiral surface of revolution, and the big footpath ball that it impels preceding storehouse moves and the path ball moves round about to feed end.Middle part, tail storehouse is equipped with the inclination collet that the member shown in Fig. 3 is spliced, the collet height is the 30-50% of grinding machine effective radius, circle is 40 °-60 ° with the angle of axis, collet makes the garden Zhou Yundong of the abrasive body-little forging that is contained in the tail storehouse increase the axially-movable component, increase movement locus, strengthen grinding effect.

The spacer assembly that is provided with between preceding storehouse and the tail storehouse is made of overflow type partition panel 4, lifting blade 5, cone 6, blind plate 7, refeed line 8.The material that preceding storehouse is levigate overflows into to be defended from the device back under gravity, little effect of shaking, inflating on a small quantity, makes coarse fodder be sunken to the bottom, is raised into refeed line by lifting blade, returns preceding storehouse through the cone inner cone and refaces, and the tail storehouse is gone in the space overflow of fines outside blind plate and cone.The overflow partition panel is an annular slab, and outer garden links to each other with cylindrical shell, near the outer garden, opens the comb hole, and remainder perforate, not perforate partly account for effectively straight craftsman 15-30% of grinding machine.Determined that by material properties and product fineness the width of the width of lifting blade, refeed line inlet equals the interval of overflow partition panel to blind plate, the refeed line inlet is close to lifting blade one end, and refeed line exports an end at the cone inner cone.

The material in exit, tail storehouse is forged and is isolated materials device by overflow blind plate 9, and lifting blade 10, cone 11 are returned and forged pipe 12, positive and negative spiral discharging tube 13 and screen cloth 14 formations.
