Technical data Target group: Owners, operators Machine type designation: BB 300 Use for the intended purpose This machine is not designed as a production machine or for continuous operation, but as a laboratory machine intended for 8 hour single shift operation. The BB 300 is suitable for crushing of medium to extremely hard substances and brittle and hard/tough materials. The achievable final fineness can be up to 5 mm and less, depending on the input material. The maximum input grain size is <130 mm.
Example 2: Sound power level LWA = 102 dB(A) Workplace related emission level Lp eq = 90 dB(A) Service conditions: Input material: Quartz pebbles, grain size <55 mm Gap width set: < 1 mm Final grain size: < 10 mm Filling of milling chamber: approx. 65% Equipment dimensions Height: approx. 1450 mm Depth: approx. 1600 mm Width: approx. 670 mm Weight: approx.

Transport and installation Target group: Owners, carriers, operators Packaging The packaging is suitable for the mode of transport selected. complies with the general packaging regulations. Please keep the packaging for the duration of the guarantee period, as your guarantee claim will be endangered in the case of a complaint or return of the machine in inadequate packaging. Transport The BB 300 must not be thrown, subjected to impact or shock during transport.
Parameters for the installation location Ambient temperature: 5°C to 40°C If the ambient temperature falls below or exceeds the limits specified, the electrical and mechanical components may be damaged or the performance data changed to an unknown extent. Humidity: Maximum relative humidity 80% at temperatures up to 31°C, decreasing in a straight line to 50% relative humidity at 40°C.
Electrical Connection The electrical connection must be established by a specialist electrician. Consult the type plate for the voltage and frequency of the BB 300. Ensure that the values are in agreement with the mains power supply. Connect the BB 300 to the mains using the cable supplied. Ensure that there is an external fuse in accordance with the local regulations when connecting the unit to the mains supply.
Operation Target group: Operators Controls and operation Graphical representation of the controls Fig.
Overview table for the graphic Control A Description ON/OFF and motor protection switch Function Starts and stops the jaw crusher motor, interrupts the power supply when the motor is overloaded. B Feed hopper Facilitates material feed, prevents inadvertent reaching into the crusher chamber, prevents ejection of process material. C Chamber for a collecting bin A collecting bin with external dimensions: height = 280mm//width = 450mm//depth = 650mm can be inserted here.
Starting the BB 300 The BB 300 may only be started with the crusher chamber empty. Process material fed into the crusher chamber or feed hopper before starting leads to blockages, and mechanical components may be damaged. The ON/OFF switch is located on the front right of the BB 300. Fig.4 Turn the switch to the ON position. The motor is started, and the moving crusher arm starts to move. The crushing process can only be started when the door is closed and locked.
Do not set the gap width of the BB 300 to below 1 mm. Mechanical components can be damaged if there is blockage. Feeding in process material The feed hopper B can accept process material with grain sizes up to 130 mm. Only fill the feed hopper and the crusher chamber when the machine is running. The feed hopper is not however intended for storage of process material: its function is solely that of feeding material into the crusher chamber.
Notes on working procedures Target group: Laboratory technicians General The BB 300 is a robust free-standing machine which can predominantly be used for preliminary pulverisation of hard or brittle materials. The performance data, throughput and achievable final fineness are dependent on the breakage behaviour and hardness of the process material, and on the gap width set. Input grain size The maximum input grain size is determined by the size of the intake opening, and is max. 130 mm on the BB 300.
General Cleaning Cleaning of the BB 300 is best effected with an industrial vacuum cleaner and a robust, long-handled brush. ! The feed hopper may only be dismantled by trained specialists, by removing the eight hexagon screws, for cleaning purposes. Operation of the BB 300 with the feed hopper removed is impermissible. Risk of crushing fingers and hands! ! Do not clean the BB 300 with running water.
Notes on setting the limit switch Remove screws S1. Remove cover A1. Release screws S2, but do not remove them. Move the bracket with limit switch E. The limit switch must operate as soon as the door is opened by max. 50 mm. Fig.9 Re-tighten screws S2. Fit cover A1 and fasten with screws S1. Perform the test as described above under “Tests” Fig.10 Replacing crusher jaws Disconnect the mains plug. Remove the feed hopper. Set the gap width to maximum. Remove cheese head screws S3. Remove clamps K1.
