Technical specifications Machine designation: BB 200 Utilization in accordance with the intended purpose The BB 200 is suitable for reducing medium-hard to very-hard substances as well as for brittle and tough materials. The ultimate fineness can be as little as 2 mm and, depending on the material being processed, may be even less.
Noise emissions Noise measurements according to DIN 45635-31-01-KL3 Characteristic noise values are dependent on the fracturing properties of the product beeing ground. Examples: Workplace-related emission value LpAeq = 84 dB(A) Operating conditions: Sample material: marble, grain size 40 - 80 mm Adjusted gap width: < 1 mm Final grain size: < 5 mm Filling ratio of grinding chamber: approx.
Shipping and installation Packing The type of packaging used has been selected in accordance with the shipping mode. It complies with generally accepted packaging guidelines. Please retain the packaging for the duration of the guarantee since, in case of a claim, returning in unsuitable packaging can jeopardize your guarantee entitlements. Shipping The BB 200 shall not be subjected to impact or vibration during transportation; it shall not be thrown.
Installation Set up the BB 200 only a flat and solid surface. Anchoring is not absolutely necessary since the vibrations transmitted to the environment by the free mass moments will be only barely perceptible. The machine may, if desired, be anchored using the holes in the feet as shown in Fig.1. Electrical connection * * * * Fig. 1 Refer to the data plate for information on the voltage and frequency at which the BB 200 is to be operated.

Starting the BB 200 The BB 200 may be started only in the idling mode, i.e. without product in the hopper or grinding chamber. The presence of product before starting will cause the machine to block and can cause damage to mechanical components. The ON/OFF and motor protection switch A/A1 is located on the left, at the front of the machine, at the left. Fig.2 * Press the button I. The motor starts and the movable arm is set in motion.
Adjust the gap width * * * * * Start the BB 200 (idling, without product). Loosen the lock nut N (turn to the left). Turn the spindle O to the right to reduce the gap. Turn the spindle O to the left to enlarge the gap. The pointer K shows the approximate gap width at the scale M. * Re-tighten the lock nut N (turn to the right). Fig. 4 Adjusting the zero setting for the gap width * * * Start the BB 200 (idling, without product). Loosen the lock nut N (turn to the left).
Working instructions Target group: Laboratory technicians General The BB 200 is a rugged, floor-mounted unit which is used primarily for preliminary grinding in preparation for final size reduction. Its continuous operating concept also makes the BB 200 suitable for integration into fully automatic and semi-automatic processing lines.
General Cleaning An industrial vacuum cleaner and a stable, long-handled brush are best suited for cleaning the BB 200. The stationary breaker arm S can also be removed to allow for sufficient cleaning of the grinding chamber. See Fig. 7 * Unscrew the machine screws F. * Swing back the fill hopper B. * Grasp the breaker arm S at the grip and pull out the pin Q. * Lift out the breaker arm S. The grinding chamber is now accessible. Assemble in reverse order. Fig.
Maintenance The BB 200 is to be lubricated from time to time. Fig. 8 Kindly refer to the table below for the quantities of grease and the lubrication intervals. The lubrication points are marked with red dots on the unit. No. 1 2 Quan. in kg 0.008 0.008 Interval, hours of operation 50 50 The points not shown in Fig. 8 but indicated with arrows are permanently lubricated. Use the grease gun supplied with the BB 200 for lubrication purposes. Ordinary multi-purpose graese can be used as lubricant, e.g.
Replacing the breaker jaws The stationary breaker arm S can be removed to provide sufficient space for dismantling the machine. Fig. 10 * Unscrew the machine screws F. * Swing back the fill hopper B. * Grasp the breaker arm S at the grip and pull out the pin Q. * Lift out the breaker arm S. * Unscrew the machine screws I. * Remove the clamping shims H. * Replace the breaker jaws J. * Assemble in reverse order. * Set the gap width as described in this instruction manual.
