Изобретение относитс к области измельчени сыпучих материалов, например минеральных удобрений, фосфогипса .The invention relates to the grinding of bulk materials, such as mineral fertilizers, phosphogypsum.

Известны измельчители, содержащие цилиндрический бункер и приводн рабочий орган, выполненный в ви;:}е вращающегос диска с отверсти ми.Grinders are known that contain a cylindrical hopper and a drive body made in vi::} e rotating disk with holes.

Известна также дискова мельница , содержаща корпус и режущий элемент, который выполнен в виде двух расположенных под углом друг к другу и установленных по спирали пил. Шаг зубьев пил увеличиваетс от центра.A disc mill is also known, comprising a housing and a cutting element, which is made in the form of two saws arranged at an angle to each other and mounted in a spiral. The tooth pitch is increased from the center.

Нетрстатком данных мельниц вл етс низка эффективность работы в виду малой степени воздействи плоских рабочих органов на весь объем дробимого материала.The net result of these mills is low work efficiency due to the low degree of impact of flat working bodies on the entire volume of the material being crushed.

Наиболее близкой к предлагаемой по технической сущности вл етс дискова мельница, содержаща корпус , смонтированный в нем-рабочий орган, выполненный в виде крестовины с ножами, и съемные сита с прижимным диском, на котором укреплен режущий элемент.Closest to the proposed technical entity is a disk mill, comprising a body, an assembly mounted therein, made in the form of a cross with knives, and removable screens with a pressure disc, on which the cutting element is fixed.

Недостатком ее вл етс также низка эффективность работы, потому что фаза малой зоны воздействи , не справл етс с предварительным дроблением материала, что приводит к снижению производительности по выходу готового продукта.The disadvantage of it is also low efficiency, because the phase of the small zone of influence does not cope with the preliminary crushing of the material, which leads to a decrease in the productivity of the finished product.

Цель изобретени - повышение интенсификации процесса измельчени .The purpose of the invention is to increase the intensification of the grinding process.

Цель достигаетс тем, что в измельчителе минеральных удобрений, The goal is achieved by the fact that in the shredder of mineral fertilizers,

0 содержащем цилиндрический бункер, установленный на раме, соосно расположенные в нем перфорированный диск, крестовину с рабочими элементами , фрезу и лопасти, шибер 0 containing a cylindrical bunker mounted on a frame, perforated disk coaxially located in it, a crosspiece with working elements, a milling cutter and blades, a gate

5 и привод, внутренн сторона бункера снабжена жестко прикрепленными Г-образными противорежущими элемен .тами, взаимодействующими с рабочими э ементами крестовины, установлен0 ной на высоту бункера.5 and the drive, the inner side of the bunker is equipped with rigidly attached l-shaped counter elements, interacting with the working elements of the cross, set to the height of the bunker.

На фиг.1 - разрез А-А на фиг.2; на фиг.2 - измельчитель, вид сверху.Figure 1 - section aa in figure 2; figure 2 - chopper, top view.

На раме 1 установлен цилиндрический бункер 2. В нижней части On the frame 1 there is a cylindrical hopper 2. At the bottom

Claims

5 hoppers horizontally mounted working body - perforated disk 3 with knives 4. Blades 5 are mounted under disk 3. A milling cutter 6 and crosspiece 7 with working elements 8 are attached to the disk. To prevent the SRI from rotating the crushed material, a disk 9 is installed above the disk Bunker rigidly attached G-riddled anti-cutting elements 10. Disk 3 with knives 4, blades 5, mill 6, crosspiece 7 with working elements 8 are fixed on the vertical drive shaft 11. The grinder works as follows. When working, the crosspiece 7 with the working elements 8, the perforated disk 3 with the knives 4, the milling cutter 6 and the blade 5 rotate together with the vertical drive shaft 11. The hopper 2 of the working shredder is loaded with barely fertilizer, phosphogypsum. The contaminated material is subjected to primary crushing by L-shaped contradictory elements 10 when interacting with the working elements ki 8 crosses 7. The pre-crushed material is crushed under the influence of the milling cutter 6, the perforated disk-J with the knives 4 and the vane 9. The finished material spills into the perforated hole disk 3 and blades 5 are carried out of the hopper

2. Installation of rigidly mounted counter-cutting elements 10 on the inner wall of the bunker 2, which provide preliminary crushing of the packed material when interacting with the working elements 8 of the cross 7, mounted on the height of the bunker, allows to significantly increase the intensification of the grinding process and increase the capacity of the shredder of grinding the adjacent materials. mineral fertilizers. The invention of the Grinder of mineral fertilizers, containing a cylindrical hopper mounted on a frame, a perforated disk coaxially disposed therein, a crossbar with work elements, a milling cutter and blades, a gate, and an actuator that is distinguished by the fact that, in order to increase the intensification of the grinding process, the inside of the bunker it is equipped with rigidly attached / l-shaped contradictory elements that interact with workers crosses, set to the height of the bunker.
