METHOD OF PRODUCING CHIPS-CEMENT PLATES Russian patent published in 2010 - IPC B27N3/00 

FIELD: process engineering.

SUBSTANCE: invention relates to construction, namely to production of chips-cement plates. Proposed method comprises logs unbarking at unbarking line, holding them for 4-6 months at drying and vaporisation site, feeding logs to crushing line, producing chips, feeding chips into mixer of chips, mortar, water, water solution of aluminium sulphate and water solution of liquid glass. Then finished mix is fed into plastic wood moulds. Filled moulds are transferred through mix placement line are stacked by stacker. Said stacker is placed under press to press the stack. Then moulds are placed for 24 h into day-long hardening chamber wherein initial hardening occurs at 40°C. Now, they are removed from said chamber, dissembled by manipulators and transferred to mold removal device for finished plates to be withdrawn and sent to face trimming and stacking. Stacks are placed for 7 day-maturing to remove moisture and acquire intermediate hardness. Note here that plates are placed on spacers in vertical position. After 7 days they are stacked. The stacks are transferred to 20 day-maturing to acquire required hardness. Complete production cycle makes 28 days.

EFFECT: production of chips-cement plates, power savings.
