SCREW MIXER SERIES DMC
For the constant and automatic feeding of water and lime mixture up to 4 granite gang-saws in the percentage requested by the operator.
Its application offers following immediate advantages to the sawing cycle:

  • perfect lime batching
  • lime mixture homogeneity
  • constant level in the feeding pump pit also without lime
  • better sawing results
  • lowering increase due to mixture homogeneity
  • time saving in the slabs washing
  • less danger of slabs oxidation

The assembled unit is compact and easy to install so it can be used in any sawmill WITHOUT SUPPLEMENTARY EQUIPMENT OR MODIFICATIONS TO THE EXISTING PLANTS.

The unit is composed of:

  1. mixer in metallic carpentry with diam. 900 mm, zinked, capacity of 700 l about of lime milk. Can be assembled with one or two batchers for powdered lime.
  2. screw batcher for the storage and automatic conveying of powdered lime into the mixer. Capacity 0,68 m3 – 680 l (about 340 kos of powdered lime). Manufactured in zinked metallic carpentry. Delivery rate varies from 10,5 to 11,5 kos/min (values variable depending on the temperatures, the humidity ratio and the age of the lime). It is complete with vibrator anti-clogging for screw and metallic grit for the choice of lime and protection against the entrance of foreign bodies
  3. electrovalve (automatic drive) allowing the entrance in the lime mixer of the clean water necessary for the composition of lime milk
  4. level probes for the automatic call of water and powdered lime
  5. pump/s conveying mixture of lime-water to the pits of the single gang-saws with circuit of “falling type”
  6. electrical control board with protection rate IP55.

SILO FOR LIME WITH AUTOMATIC DOSING AND MIXING SERIES S
This replaces the screw-operated lime batcher on fully automated systems. It achieves big operating autonomy with the following advantages

  • reduced need for operator control
  • labor savings
  • saving in lime costs

The silo is loaded directly from duly-equipped tank trucks using a suction system. Lime is instroduced into the mixer by a programmed variable screw. The lime mix is sent to the gang-saw feed pits by a closed circuit pump and travels through stainless steel solenoid valves controlled by level probes. These silos are made of a metal load-bearing structure with plating that can be built at the installation site according to our drawings (when shipping costs – expecially for foreign sales – make this more economic).
The volume of the silo varies from m3 23,9 (height 9130 mm) to 37,3 (height 12760).
