Processing of natural clay material manually unlike wet clay material before processing, because this processing technique has been using a variety of equipment masinal is driven by electric power equipment such as blunger, Pugmill, and filterpress, with the equipment provide a speed advantage and processing quantity of clay that can be processed.
This clay material processing can be either one type or a mixture of clay with Earthenware Earthenware, Stoneware with stoneware, Stoneware or Earthenware with. To a mixture of several types of natural clay, formulas (recipes) clay mixture should also be well documented.
Processing
Natural clay material processing by means masinal wet technique performed through the following stages:
1. Drying
Jemurlah natural clay Earthenware or stoneware form, preferably in the form of small pieces meant that the water contained in the natural clay that quickly evaporates faster drying process.
2. Weighing
Timbanghlah clay when a mixture of some type of clay using existing scales. Weighing should be done thoroughly when the soil body clay in the form of a mixture of several according to the type of clay percentage weight of the formulation (recipe) clay that has been made, then put in blunger.
3. Mixing and stirring
Mix the clay material was weighed and then enter into the blunger has been filled with water, then blunger operated for one hours, then after the motor cold running again. Perform stirring until the mixture to mud clay homogeneous in consistency right, so easily filtered.
4. Filtering
Strain mixture of soil clay in the form of a slip by using mesh sieve size 50 to 80. Filtering is done in order free of silt clay impurity materials such as: plant roots, charcoal, gravel and so on. Enter a land slip clay on the screening results containers and tubs or buckets ready thickened with filterpress.
5. Thickening
Perform coagulation land slip clay that has been filtered with pump slip into fabric filter bags filterpress with the help of compressor. Filterpress function to reduce the water content (Dewatering) in soil slurry by pressing clay slip clay into the fabric filter. Open filterpress grab a slab of clay plastic (clay cake) results thickening clay slip.
6. Penghomogenan
Perform soil penghomogenan clay by putting in Pugmill. Pugmill function to homogenize and soil compacting plastic by pressing clay plastic in the hole Pugmill until full. Do it continuously until the clay plastic cylindrical exit subsequently cut with wire cutters, then put in the bag plastic.
7. Ripening
Peramlah plastic clay on tub or container with a lid airtight so humidity The plastic clay remains awake. Perform curing for approximately 7 days, the longer the curing time the quality of the plastic clay the better, because the fermentation process of organic elements it contains, so the ground become more plastic clay.
