1. Purpose

Dewatered cake produced in the dehydrator, which is in the final process of the turbid water treatment system, is just industrial waste if no further treatment is done. This dewatered cake is recycled into a resource by processing it in a cake-recycling machine for stable treatment giving it strength.
The product is named CAKLE II (CAKLE).

2. Efficiency and features

Models: 30 type and 50 type
Treatment capacity: 30 to 50 t/h
Stabilizer: Unsliced lime, cement, etc.
The amount to be added differs according to the properties of the cake and application. In general, it is about 1 to 2% when cake is used to improve soil and about 3 to 4% when cake is used as a base course material.

Application to soil treatment
(1) Improving soil
Back filling, banking, backing, embankment, land creation, park, ground, piping embedding material, raw material for cement, etc.
(2) Base course material
Mixed with crusher run and RC material and used as a base course material

3. Characteristics

(1) CAKLE has a compact integrated structure, five processes are carried out continuously in short order; fixed-quantity cutting-out of cake, crushing, addition of stabilizer, mixing, and crushing.
(2) The uniquely structured cutting-out and crushing mechanism smoothly performs fixed-quantity cutting-out and crushing of highly viscous cake.
(3) Sufficient strength can be obtained with the addition of only a small amount of stabilizer because the stabilizer is added after the cake has been crushed into strips of several millimeters.
(4) When cake is used as a base course material, the size of 95% or more of the product can be reduced to 5 mm or less.

4. Structure

The structure is as shown in Fig. 1.
(1) The receiving hopper itself rotates slowly and a fixed quantity of cake is cut out from the stationary cutter in the bottom section.
(2) Cake, which is cut out, is crushed into strips of several millimeters by the crushing machine.
(3) A fixed amount of stabilizer is added to all parts of the stripped cake.
(4) Cake is fully mixed by the multi-shaft type mixing and crushing machine, and then, it is crushed to a size of 5 mm or less.
