Description

Basically zkt. St. L 43322 describes a method for preparing a well-known 1 olan cement, in which pozzolans 1 are used as the starting material for artificial plastics 1: the burning rocks are crushed, crushed in nde otros1 with j-; aN; eniioro corner, and predstanl yush. not himself nodver; chines sag: ovo gorni1o is otva; 1aX c.ec; i HycToii rocks with coal. Burned rock in cMCCii with a pctnizer is subjected to heavy treatment for about 5 minutes.

The disadvantages of this method are without adjustment, nods; 1, B, resulting in unopened components, as well as several and other end elements. worse than (1) shchpa quality vypuschemoght cement. In addition, with this method of ne.) Tc are large fractional resins, which are located in dumps (ternkonpkah).

A distinctive feature of the ired.tagelco method consists in the fact that this rock is broken up before being ground and mixed with the actinator undergoes fractionation with the aim of separating unfired components from the burned rock and not large, as a building rubble, medium fractions with the most stable characteristics cement and fine fractions as building sand and gravel.

The process of separating the unburned components is carried out in two steps, with the small unbaked parts of clay enveloping the calcined rocks first by cutting the rock through a vibrating device, and then, to separate large pieces of green blasted impurities, the rock is subjected to a blow to the firing slab, followed by sorting the rock by size sieves with the release of burnt rock for the production of cement, sand, rubble and gravel.

FIG. 1 shows a horizontal section of an installation for carrying out the method; on fit. 2-section aa on fng. one.

The essence of the method,) 1kets and the following; from the tercoiik it burned with a float by a trolley / scrubbing conveyor, or in another way it was fed into camper 2 bunker 2, where groups of rock were crushed into smaller pieces of 25-60 mm.

Burned rocks after leaving Kamkedrob 11, Tkn come through the Vorik on the internal wedge consisting of a series of pan (grooves). Due to the vibrations and currents of the air, which goes towards the burning rocks, they are subsequently shaken and freed from the particles enveloping them, which are burnt or weakly burned clays and other inclusions. An air cyclone is mounted in the vibro-silky aggregate, thanks to which all dust fractions of the burning fractions of the burning rocks that are burning, but also more expensive than the unbaked or s.chabo burnt species, are released and thus free the valuable burnt norm.

Upon leaving the vibrating-susceptible aggregate of the burned rock, it is directed to a valuable elevator 4 with a specially arranged device for regulating, striking the burnt-out rock on a metal board, inside a bucket, designed from 11 tons of sieves.

The most sensitive fragments of the Jesmanic and other inert, inert, sonorous burned rocks are separated from the rest by nerve sieve and go through the trays to the skins of bread and butter 5.

Well burned burnt rocks, of lower mechanical strength, are passed to the second sieve and set to be prepared for chewing through the hopper 6 and the metering devices on the ball mill 7 mixed with the actuator and according to 1 and 1 in 1 in the bunker.

Small fragments of sandstones are partially woeful on the third sieve and go to the warehouse of the gravity 8. Very small fractions fall on the fourth bed and leave 1a sk.1ad sand.

The dust-like unsuitable fractions are deposited on a new sieve and the i-a warehouse leaves.

In a ball mill, enriched grief, which comes together with an activator, is subjected to fine grinding and, however, the skip stand 9 is fed to the hopper 10. Cement obtained after leaving the mill is not active.

Rubble, sand and splits can be used as modern materials for construction or other purposes.

Thus, the proposed method decides, comnodexually, the question of isno, the use of burnt hydrogen and the production of high activity cement, crushed stone, sand and gravel from them.
