SU1435291A1 - Mill for wet grinding of materials - Google Patents

Abstract

The invention relates to a device for grinding materials and improves the efficiency of grinding and reliability of the mill in operation. The wet grinding mill contains a cylindrical body 1. In the lower part of the body there are pallets 3 and 4 with drainage hatches for trapping non-crushing objects. The mill body is divided by partitions 6 into three chambers, the outermost of which is for coarse grinding, and the middle one for fine grinding. A three-sectional rotor is installed in the body, the working elements of the extreme sections are filled with a blade shape, and the middle one is rectangular. On the side surface of the housing 1, removable sieves are installed, through the openings of which the finished material flows through the chute into the discharge pipe and then into the drainage basin. To prevent the release of comminuted material, the feed funnel 22 is lined with a prismatic shape and shifted toward the discharge of the finished product. 1 hp f-ly, 4 ill. i SL

The mill for wet grinding of materials contains a cylindrical box mounted in two supports 2. In the lower part of the hull there are pallets 3 and 4 with drainage hatches 5 for pressing indented objects and emptying the mill when replacing a faulty rotor and for other repairs. The mill casing is divided by partitions b into three chambers, the middle of which is for coarse grinding, and the outer ones for fine grinding. Removable stationary sieves 8 with round and 5 mm diameter or 5 mm diameters are installed on the side surface of the housing 7. Through the openings of these screens, the finished material enters: Through the chute 9 into the discharge port 10. Inside the case there is a rotor, consisting of a horizontal shaft P 5 on which are hingedly fastened with the help of holders 12 and .13 of the sleeve-shaped working elements 14 and 15 of the lamellar and blade Forms 5 that grind the material, respectively, in chambers for coarse and fine grinding. The rotor is mounted in two roller bearings 16 and is driven by a 17-wheel drive. Tank fittings 1 are sealed at the exit of housing i and are provided with a stuffing box is by supplying pressurized water to it through pipes 19 Shield 20 serves to guide the material .la, discharged through a sieve 8 to the bottom of the gutter 9.

The crushing chamber is designed to replace work items without disassembling the casing.

The mill works as follows.

Through the feed funnel 22, the material enters the housing 1. To prevent the release of comminuted material, the feed funnel is prismatic in shape and shifted toward the discharge of the finished product. The vacuum generated in the metal housing due to the continuous removal of material through sieves promotes the material. from the grinding chamber into the grinding chamber and subjected to the action elements of the rotor. From the discharge port 10, the finished material is transported by gravity to a drain pool (not shown).
