Definitions

  • the invention relates to a batch mixer for mixing face mix and a method for mixing face mix for use as a concrete overlay.
  • the face mix can contain colouring means and it can be textured in a variety of ways to resemble other materials, similarly to stamped concrete.
  • face mix is particularly difficult to mix i.e. it is a known problem that it is difficult to get the added water distributed evenly in the entire mixture during a face mix mixing process. If the water is not fully and evenly distributed in the mixed batch of face mix the quality of the face mix is severely reduced.
  • An object of the invention is therefore to provide for an advantageous mixer for mixing face mix and an advantageous method for mixing face mix.
  • the invention provides for a batch mixer for mixing face mix.
  • the mixer comprises a mixing pan including one or more discharge openings and a mixer unit comprising a mixer unit drive and one or more mixing means.
  • the mixing pan comprises water nozzles for adding water into the material being mixed in the mixing pan during a face mix mixing process, wherein the water nozzles are arranged in the bottom half of the mixing pan.
  • Using a batch mixer for mixing face mix is advantageous in that this type of mixer is particularly efficient at mixing large batches of fine-grained material together.
  • batch mixer is to be under stood any kind of mixer comprising a mixing pan with rotating mixing means extending down into the mixing pan.
  • a batch mixer all ingredients are loaded into the mixing pan together or in a pre-defined sequence, and mixed until a homogenous material is produced and discharged from the mixing pan in a single lot.
  • Batch mixer does not include so called “Continuous mixers” where the ingredients are continuously charged into the mixer and where the mixing takes place as the material travels from the charging port(s) to a discharge nozzle, from where it is continuously discharged.
  • Batch mixers exist in a number of design variations and are also known under other names such as counterflow mixer, countercurrent mixer, planetary mixer, stationary pan mixers and vertical axis mixers.
  • bottom half is to be understood the bottom half of the mixing pan which is closes to the ground when the batch mixer in placed on the ground and orientated so that it is ready for use as a batch mixer.
  • a front end of said water nozzles are arranged substantially flush with the inside surface of said mixing pan.
  • the nozzle extends too far through the wall, the walls cannot be scraped clean in the mixing process and the subsequent emptying process, which will extend the mixing process and reduce the quality of the mixed substance. If the front end of the nozzle is retracted too far back into the wall the risk of unwanted material build-up in front of the nozzle is increased, hereby also increasing the risk of clogging the nozzle is increased and increasing the risk of solidified lumps of grout or other material is mixed into the mixture so that the quality of the mixture is reduced.
  • arranging the water nozzles substantially flush with the inside surface of the mixing pan is advantageous in that it reduces the risk of solidified material entering the mixture in the pan while also reducing the risk of clogging the nozzles.
  • said water nozzles comprises penetration adjustment means for adjusting how far the front end of said water nozzles extends into said mixing pan as seem form the outside surface of said mixing pan.
  • the inside surfaces of a mixing pan of a batch mixer are wear parts because of the intense abrasion caused by the constantly moving mixture which constantly grinds the inside surfaces of the pan.
  • said water nozzles are located in a sidewall of said mixing pan. If the nozzles are placed in the bottom of the pan the risk of them being clogged is increased due to gravity pulling material down into the nozzles. However, by placing them in the sidewalls the risk of clogging is reduced. Furthermore, it is easier to maintain, exchange and adjust nozzles placed in the sidewalls since these are much more accessible that if they were placed in the bottom surface.
  • said water nozzles are located between 1% and 50%, preferably between 3% and 40% mm, and most preferred between 5% and 30% of the full height of said sidewall above said bottom of said mixing pan.
  • the mixer can only be used for making large batches or else the nozzles will not be placed below the surface of the mixture in the mixing pan.
  • the nozzles are placed too close to the bottom of the pan the risk of water concentrations at the corner between the sidewall and the bottom is increased hereby reducing the efficiency of the mixer and reducing the quality of the final mixture.
  • the present placement ranges present an advantageous relationship between capacity of the mixer and efficiency.
  • a water exit opening in said water nozzles is formed conically.
  • Forming the nozzles with a conical exit hole is advantageous in that it reduces the risk of material build-up in the exit hole and it makes it easier for the water to flush the exit opening and thereby ensure that the nozzle is clean and usable.
  • said water nozzles are made of hardened steel. Especially the front end of the nozzle will be exposed to intensive wear and it is therefore advantageous to make the nozzle of hardened steel to increase its life.
  • said water nozzle comprises one or more water entrance openings and one or more water exit openings and wherein the total area of the water entrance openings is bigger than the total area of the water exit openings.
  • said water nozzles are formed as separate parts mounted in the bottom half of said mixing pan.
  • the term "separate" in this context refers to the nozzles being manufactured separately before they are mounted in the mixing pan. I.e. during use the nozzles form part of the mixing pan but they are not formed integrally with the mixing pan, in that they are releaseably mounted in the mixing pan and therefore can be dismounted.
  • said mixing pan is stationary and two or more suspension arms are extending between said mixing pan and said mixing unit hereby suspending said mixing unit above said mixing pan.
  • the invention provides for a method for mixing face mix for use as a concrete overlay.
  • the method comprises the steps of:
  • aggregate any kind of sand, gravel, rubble, grit, stones or any combination thereof suitable for making face mix.
  • said water is added to said mixture by means of water nozzles arranged in the bottom half of said mixing pan.
  • said method further comprises the steps of emptying said batch mixer where after said water nozzles are cleaned by pushing water out through said nozzles. Cleaning the nozzles by means of the water pressure is advantageous in that it is readily available and it is an efficient way of keeping the nozzles in working order.
  • said colouring means are dye, granulate or liquid colour.
  • said optional colouring means are mixed at least partly into said aggregate before cement is added.
  • Mixing the colouring means at least partly into the aggregate before cement is added is advantageous in that it is highly important for the quality of the face mix that the colouring means are evenly distributed in the mixture and that the colouring means therefore is added to the mixture as early in the mixing process as possible.
  • the colouring means is the first ingredient to be added it will stick to the inside surfaces of the mixer and the risk of it not being evenly distributed in the final mixture is therefore increased.
  • by adding it to the aggregate it is ensured that it can be mixed properly into the mixture.
  • said water is not added until after aggregate, cement and optionally colouring means have been feed into said mixing pan.
  • Cement and colouring means are very fine-grained and if the water is added before these ingredients the risk of these ingredients not being mixed properly into the mixture is increased. Particularly because the risk of the moisture not being distributed evenly will increase.
