In the aforementioned calcium carbonate classifying, crushing and screening device, each pair of the rolling rollers are in the shape of gears corresponding to each other.
Compared with the prior art, the utility model discloses with jaw breaker, roll the roller, primary filter screen and second grade filter screen combine integratively, calcium carbonate directly carries out breakage at this device, smashes and screens, smashes the calcium carbonate granule that the back filtered out through setting up primary filter screen and second grade filter screen and reach required standard, screens calcium carbonate granule as required through setting up the second grade filter screen and select coarse grain and fine grain, carries the pay-off mouth again through setting up the calcium carbonate granule that vertical type hinge dragon conveyer will filter out and circulate and smash, adopt the utility model discloses carry out calcium carbonate screening, need not to carry out many times between rubbing crusher and screening machine and smash and filter many times, can directly carry out breakage, the circulation automation operation of smashing and screening, its work efficiency is higher relatively. The utility model discloses combine into the integration operation with breakage, crushing and screening to carry out the operation that circulates through vertical type hinge dragon conveyer, the staff need carry out a lot of collection, throw operations such as material many times, only need throw the collection operation after material operation and the screening, its work load is less relatively.
So the utility model has the advantages of relatively high working efficiency and relatively small manual workload.
Furthermore, the primary filter screen and the secondary filter screen are arranged to be of a structure which is inclined downwards from the middle to two sides, so that coarse particles can automatically slide down under the action of gravity during filtering. Through establish rotating base and hydraulic means at coarse fodder tank bottom portion additional to can control the coarse fodder tank and rotate, make the unable effective landing of coarse grain that falls of self-propelled landing that gathers on the secondary filter screen.

Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. A calcium carbonate classifying, crushing and screening device is shown in figure 1 and comprises a box body 1, wherein the box body 1 is divided into a crushing chamber, a crushing chamber and a screening chamber from top to bottom; a vertical auger conveyor 9 is arranged on the right side of the box body 1; a jaw crusher 2 is arranged in the crushing chamber; the crushing chamber comprises a plurality of pairs of rolling rollers 3 arranged right below a discharge port of the crushing chamber, a primary filter screen 41 arranged right below the rolling rollers 3 and a feed back pipe 5 arranged at the bottom of the crushing chamber; the screening chamber comprises a coarse material groove 6 arranged at the bottom of the box body 1, a fine material chamber 8 arranged in the coarse material groove 6 and a secondary filter screen 42 arranged at the top of the fine material chamber 8; the top of the vertical auger conveyor 9 is provided with a discharge pipe which extends to the upper part of the feed inlet of the crushing chamber; a material collecting pipe 91 is arranged on the left side of the vertical auger conveyor 9; the material collecting pipe 91 is connected with a material return pipe 5 penetrating through the box body 1.
The bottom of the crushing chamber is in a shape of a funnel which is contracted downwards; a conveying pipe penetrating through the crushing chamber is connected below the primary filter screen 41.
The primary filter screen 41 and the secondary filter screen 42 are both of structures which are inclined downwards from the middle part to two sides; the filtering specification of the secondary filter 42 is higher than that of the primary filter 41.
The bottom of the rough trough 6 is provided with a rotating base 7 and two groups of hydraulic devices 71 which are respectively positioned at two ends of the bottom of the rough trough 6.
