The mill provides grinding of agricultural crops according to the current standards regulating methods of determining their quality. Principle of operation: grain is fed into the mill dispenser, where an air-grain mixture is formed, which enters the grinding chamber. The crushed product is separated from the air in the cyclone and collected in a special removable container. After the grain supply is stopped, the air flow ensures self-cleaning of the dispenser and the grinding chamber of the mill. application It is used in the preparation of samples to determine the quantity and quality of gluten, the "drop number" and other indicators of the quality of crops by infrared spectroscopy and other laboratory analysis methods, which require a high degree of grinding of samples. The CALIBRE differs from its predecessor, the BOREY laboratory mill, by a drastic reduction in overall and weight characteristics. An additional advantage of the CALIBRE mill is the reduction in the number of structural elements. So the absence of the door of the grinding unit makes it possible for quick access to carry out work on cleaning the grinding headset. technical specifications: Volume of the receiving funnel, ml 400 Permissible amount of ground product per hour, kg 3 The grinding time of the suspension is 50 gr., from 25-35 The maximum size of the crushed product, mm 12 The diameter of the sieve holes, mm 0.8; 1.0 The speed of rotation of the grinding hammers, rpm 16 500 Minimum mass of the milled product, g 10 The maximum mass of the milled product, g 300 Overall dimensions, mm 400 x 445 x 400 Weight, kg 26 Noise level, dB 70 Power supply Single-phase AC 220 V, 50 Hz Power, W 1050 The response time of the overload protection system, from 2 GENERAL CHARACTERISTICS: 1. Reproducible sample preparation process: The mill is equipped with a sieve with round holes with a diameter of 0.8 mm*, which makes it possible to obtain a finely dispersed product with a stable particle size during grinding. On a separate order, it is possible to complete a sieve with holes with a diameter of 1.0 mm. 2. Quick and easy cleaning The cyclone-exhaust system of the mill provides self-cleaning of the grinding chamber. The ledges and holes in which the ground sample can be collected are minimized. 3. Low noise The vibration and noise insulation system of the CALIBRE mill allows, with considerable power and productivity, to ensure comfortable work of personnel during the working shift. 4. Maximum safety and ease of operation The closed grinding chamber ensures safe operation of the mill. The thermal overload protection system turns off the electric motor when it stops during the grinding process.

The working condition of the ND-400(R) diffusion pump depends on the temperature of the working fluid in the pump boiler. During the initial filling, it is recommended to fill the maximum volume of the working fluid. Working fluid is "VACMA OIL 500" vacuum oil (under technical specifications TU 19.20.29-061-00218526-2019). The total amount of working fluid in the ND-400(R) diffusion pump is a maximum of 5 liters, a minimum of 3.3 liters. The viewing window for visual inspection of the working fluid has marks of its maximum and minimum amounts. During normal operation of the pump, the level of the working fluid practically does not change. The temperature of the working fluid when the pump is operating at the maximum residual pressure is about 240°C to 255°C. It is recommended to monitor the operation of heaters in the ND-400(R) diffusion pump using one temperature sensor. The temperature sensor must be installed in a special radiator socket above the heater. If there is a loss of working fluid and an increase in the temperature of the radiators of the ND-400(P) diffusion pump to 320°C, the temperature sensor must give the command to automatically turn off the heaters. The subsequent activation of the pump heaters should not be automatic and should be performed only after cooling the system. Water at the inlet to the cooling systems of the housing and the oil reflector must be supplied with a pressure of 0.3 MPa (3 kgf/cm2) to 0.5 MPa (5 kgf/cm2) and a temperature of plus 4°C to plus 25°C. The recommended cooling water consumption for the housing is 250 l/h, for the oil reflector it is 40 l / h. It is regulated by the outlet water temperature, which should not exceed plus 40°C. The water drain should be free (with a jet break).
