Definitions

  • the present invention essentially relates to a process for grinding and compacting any mineral material, such as for example cement clinker.
  • roller presses for grinding and compacting various mineral or organic materials has been known for a long time. It is also known that, in order to obtain regular operation of the roller presses, the material feeding the press should be preconditioned to avoid excessive swelling of the feed.
  • Grinding plants are also known which are provided with rollers allowing prior grinding of the material to be ground, which makes it possible to pre-compact the material before applying the final grinding force.
  • the present invention aims to remedy this drawback in particular by proposing a method and a grinding installation which make it possible to ideally precondition the material feeding the press, which can thus work optimally.
  • the subject of the invention is a process for crushing and compacting any mineral material, such as for example cement clinker, and of the type consisting in preconditioning this material before crushing it in a press.
  • rollers or the like characterized in that the preconditioning of the material consists in mixing various forms of the material feeding the press in order to regulate its bulk density at a value of between approximately 0.60 D p and 0.90 D p , D p being the density of the agglomerated or compacted product leaving the press, in order to ensure stable operation of the latter and therefore stabilize the instantaneous energy consumption necessary for grinding.
  • This process is further characterized in that the bulk density of the material feeding the press is between 0.68 D p and 0.85 D p .
  • the bulk density at the press feed is regulated between 1.7 and 2.05.
  • the invention also relates to a grinding and compacting installation for implementing the process meeting the above characteristics and of the type comprising a roller press or the like allowing the grinding and partial agglomeration of a material. any mineral, and downstream of this press, a means of transport associated with a distributor system and allowing the recycling of part of the cased and partially agglomerated material towards the press supply.
  • This installation is characterized in that the other part of the material leaving the aforementioned distributor system feeds a second distributor system, one outlet of which communicates with the aforementioned means of transport, thereby regulating the quantity and density of the crushed and partially agglomerated material recycled. to the feed to the roller press.
  • one of the two aforementioned distributing systems is a screen, a sieve or the like.
  • roller press is supplied with mineral matter coming from a pneumatic separator or an equivalent system connected to the supply of said press by at least one pipe fitted with a third system.
  • distributor whose outlet is connected on the one hand to the inlet of the roller press, and on the other hand to the other outlet of the aforementioned second distributor system.
  • a density measuring device is advantageously arranged at the entrance to the press.
  • the installation visible in the single figure is a grinding installation in a closed circuit comprising a press 1 with rollers 2, the inlet 3 of which is provided with a device for measuring the density of the products feeding the press. 1, which device is schematically identified in 4.
  • the press 1 is supplied with raw products as materialized by line 5, with a ground product and partially agglomerated by the press and recycled, as materialized by line 6, and with grainy or powdery products, as materialized by line 7, these latest products from a pneumatic separator or equivalent system 8.
  • the separator 8 receives a mixture of ground products, as will be described in detail below, and this by line 9, and it separates said mixture into a fine and finished product which is discharged in suspension in the gases extracted via line 10 , and in a grainy or pulverulent product which leaves the separator 8 via the pipe 11. It will be observed here that the separator 8 ensures, at the level of the bodies for distributing the material, a deagglomeration function.
  • the crushed and agglomerated product forms a flow 12 passing through a first distributing system 13 dividing the material into two partial flows marked at 14 and 15.
  • the flow 14 essentially comprising compacted plates is recycled to the input 3 of the press 1 by a means of transport 16 connected to the line 6 previously mentioned.
  • the other part or flow 15 of the material leaving the first system distributor 13 feeds a second distributor system 17 dividing the flow of crushed and partially agglomerated product on the one hand into coarse elements leaving through the line 18 communicating with the means of transport 16, and on the other hand into fine products leaving through the line 19 .
  • the line 19 could lead directly to the conveyor 20 recycling the fine products to the inlet of the pneumatic separator 8 via the line 9 mentioned above.
  • the separator 8 outlet pipe 11 is equipped with a third distributor system 21, the outlet of which is connected on the one hand to the line 7 leading to the inlet 3 of the press 1, and on the other hand, although this is not shown, at the outlet 19 of the second distributor system 17, via a conduit or the like 22, for the purpose of directly recycling the grainy product to the feed of the separator 8.
  • the installation includes additional grinding equipment shown diagrammatically at 23 which can be constituted by a ball, bar, vibrating, impact or similar mill.
  • outlet 19 can be equipped with a distribution flap 24 for the finished products leaving the second distribution system 17.
  • the distribution flap 24 subdivides the material which reaches it into two lines, namely a line 25 terminating in the crusher 23 and a line 26 terminating in the conveyor 20, which also receives the ground products extracted from the crusher 23 by the line 27.
  • the duct 22 instead of being directly connected to the outlet 19 of the second distributor system 17, is here connected to the inlet of the crusher 23, which may include ventilation which can be used to extract at least part of the ground product.
  • the density in bulk or of the mixture of the various forms of the material fed to the inlet 3 of the roller press 1 by the lines 5, 6 and 7 will be modulated in such a way that it lies within a range allowing stable operation. of the press, and this essentially by modulating the proportion of recycled platelets in line 6, by actuation of the first distributor system 13.
  • the aforementioned bulk density will also be advantageously modulated by acting on the third system distributor 21 to modulate the proportion of granular products passing through line 7.
  • the second distributor system 17 also intervenes for the regulation of the bulk density of the products feeding press 1 since, as we understand, it plays a role as regards the quantity of plates leaving the first distributor system 13 and recycled at the inlet 3 of the press 1 via the transport means 16.
  • the second distributor system 17 or the first distributor system 13 can be constituted by a screen, a sieve or the like.
  • the bulk density of the material feeding the roller press should have, according to an essential characteristic of this invention, a value between 0.60 D p and 0.90 D p , D p being the density of the agglomerated or compacted product leaving the press.
  • the density of the material feeding the press will preferably be between 0.68 and 0.85 D p, it being understood that the density regulation giving the press excellent operating stability can be achieved in any suitable manner.
  • the density measuring device 4 located at the inlet 3 of the press 1 will advantageously and at all times allow the density of the products feeding said press to be controlled, this device possibly being able to act automatically on the distributing systems. 13 and 21.
