Description

The invention relates to continuous slaking machines for lime, equipped with milling drums for grinding lime clods and sprinkles for watering the material to be ground.

In the known machines of this kind, the obtained milk of lime, containing its solid inclusions of underburning, must be passed through additional devices in order to separate large solid inclusions, which lower the quality of milk of lime. Additional devices complicate and increase the cost of the preparation of lime milk, and the transition of part of the raw material to waste reduces the yield of the product.

In the described machine, this disadvantage is eliminated by the fact that, in order to use the obtained milk of lime without separating large inclusions, twin milling rollers are installed under the milling drums with an adjustable wedge between them to further crush large incinerate inclusions to allowable particle size.

The drawing schematically shows the described machine in cross section.

In the upper part of the fixed body / machine, ending with a coius bottom 2 with a hole 3, there are two milling drums 4 rotating in the direction of the arrows shown in the drawing. Milling drums are designed to grind lime clods in the presence of water. For irrigation of the material being crushed with water, showers 5 are located in the lid of the upper part of the body.

The lumpy lime is loaded and crushed and loaded into a bunker 6, the bottom of which is made in the form of two turning flaps 7, opened using handwheels 8 and hinged levers 9. For uniform and continuous feeding of lump lime from the bunker to the milling drums of the shutter 7, they are periodically shaken by means of hinges rtch1 10. interacting with cam copiers //,

mounted on the shafts of the drums 4. With noiviouiH handwheels S, by more or less opening the shutters 7, you can .regulate the amount of lump lime supplied per unit of time.

Irrigated with water, located on the milling drums, clod lime is quenched, transformed into milk of lime.

Milling drums, grinding lump lime, contribute to its rapid quenching. Nedozhod, however, containing ice in a clod of lime in the form of large solid inclusions, passes through milling drums insufficiently crushed and cannot be applied to the Cause together with the resulting lime milk. In order not to separate these large particles of underburning and use them together with the resulting milk, under the milling drums there are paired, rotating in different directions rolls 12 and 13, which crush large particles of underburning to an acceptable value. The gap between the rollers of each pair of rollers can be adjusted in size by expanding the rollers, which are driven by a system of gears 14 and 15.

Subject invention

A continuous slaking machine for lime, equipped with milling drums for grinding lime clods and sprinkles for watering the crushed material, characterized in that, under the milling drums, to use crushable milk of lime containing solid inclusions of underburning, without additional separation of large inclusions, under milling drums paired rollers with an adjustable gap between the two for additional crushing of large incineration inclusions to acceptable values particles.
