Quality of grinded grain is one of the critical parameters of grinders, which allows decreasing the starch losses, and, as the result, ethanol losses. The installed HAMMER MIL grinders (90kW, 1500r/min) are designed to crush stone and provide the grinding coarseness of NO MORE than 92% with mesh size of about 1.0mm. Restoring of grinding plates is necessary to be provided in order to upgrade the quality of crushing up to the required 96 … 98% of passage through the similar sieve. The edges of grinding plate MUST be sharp, not rounded. The sharp edges can be made by overlaying/welding-on a plate with following edges cutting.
The main point and method of measure implementation has been thoroughly explained while performing the 1st stage of the audit and need no additional explanations or comments. Economic indicators of the suggested measure are shown in Table 7.4.1. It is offered to restore both of the grinders.
