Tsiglomen sawmill: first results. To be continued
3 December 2012
September 2012 new sawmill production launch finalized the first stage of modernization of Tsiglomen production sector of Sawmill 25 (Arkhangelsk).
Currently the new sawmill produces some 1000 cubic meters of sawn timber (under one shift operation).
The second stage works are going at full tilt, their result should be launch of drying complex (consisting of several progressive and compartment kilns), dry board sorting section and a mini-CHP, its capacity making up some 19 MW of thermal power and 3 MW of electric power. It is planned that in spring 2013 the second stage works will be finalized and the sawmill in Tsiglomen will reach its designed capacity, which is 800 cubic meters of round logs processed under 3 shift operation.
Let us get back to beginning of 2011when the contract for equipment delivery for construction of a new sawmill at Tsiglomen was signed.The choice of equipment suppliers is not an easy task, but the Sawmill solved it easily and quickly. Experience of successful construction, launch and work of Maymaxa sawmill sector completed in 2006 to a great extent influenced the choice.
This is also the best evidence that they at the Sawmill are satisfied with the result of the certain equipment operation and the cooperation with the equipment suppliers in general.
Trust is convenience
In spite of technological similarity of the two projects, the new one is pretty much different in terms of project implementation – construction of Tsiglomen sawmill sector is performed with participation of a general supplier. According to Sawmill 25 Managing Director M. Papylev, during construction of Maymaxa sawmill sector all the equipment supplying companies worked independently. With this experience in mind it was decided that it is much more convenient and easier to work with a general supplier than with separate companies. "Ability to achieve mutual understanding with the customer, clear understanding of its obligations, high level of responsibility for the decisions made – that is what we appreciate Hekotek for as a general supplier", commented M. Papylev.
Similar not identical
Today nothing stands on the same point, and the new plant equipment will be much more advanced compared to the sawmill in Maimaxa.
Thus, sawline inTsiglomen (by Linck, Germany) allows sawing of more side boards, due to extra profilers added to a construction line. The line is also equipped with an optimized side boards cutting system. As for the curve sawing option, it was again decided unnecessary for the purpose of the sawmill.
Two green board sorting lines in Tsiglomen also make a significant difference compared to Maimaxa where no sorting line for central boards was provided at all (central board are straight directed to stick stacker). The situation in Tsiglomenis different - 5 separate horizontal sorting bins are installed there to provide a particularly gentle board handling, and also increasing good yield.
However, the fact of installation of the two green sorting lines (by Hekotek, Estonia) does not necessarily imply simultaneous operation of them both. For instance, when sawing small logs the system directs all the boards to one sorting line (mainly meant for the side boards). As a result, the sawmill has more accurate and efficient use of labor, as well as electricity consumption.
A considerable amount of electricity necessary for the sawmill production will be provided by a CHP. Manufacturing practices in Maimaxa shows that neither drying facilities, not the the sawmill as a whole consume the entire amount of thermal power generated to obtain the maximum possible amount of electric power. It is there fore important to use this excess heat efficiently and effectively. In Maimaxa it is used for drying sawdust, which are directed to wooden pellets production.
In the near future Sawmill 25 plans to construct a similar pellet mill in Tsiglomen, whose power at the first stage will be up to 60 thousand ton per year. Belt dryer for drying sawdust consuming all the surplus heat generated by CHP allow drying up to 9-11 ton of sawdust per hour. The pellet mill will be the most logical solution in terms of an effective full closed production cycle. In addition to recycling and consumption of excess heat, the pellet mill in Tsiglomen will provide fuel for the local pellet-burning boilers, built in near by villages about 3 years (boilers houses supplier - Hekotek) and successfully operating for the third heating season.
Secret of success
Ability to invest smartly has always been lineaments of Sawmill 25. This is the pillar stone of this enterprise success. Perfectly designed, constructed, and – most important– effectively operating sawmills is a natural result of the daily hard work, which is calculated not only by the number of working hours spent. The key to success also lies in the ability to analyze a situation, make correct forecasts, find reliable partners and– by all means – in desire to develop the enterprise for the benefit of the region and all its inhabitants’ prosperity.
