Safety Target group: Anyone who deals with the machine in any capacity whatsoever. The BB 100 is a modern, high-performance product manufactured by the Retsch GmbH, incorporating state-of-theart engineering.
Warnings The following symbols are used to identify specific hazard potentials: Personal injury ! Property damage Repairs These operating instructions do not include any repair instructions. In the interest of your own safety, have repairs made exclusively by the Retsch GmbH or an authorized representative (service technician).
Technical specifications Machine designation: BB 100 Utilization as per the intended purpose This unit is not designed as a production machine, but as as laboratory device intended for 8 hours single shift operation. The BB 100 is suitable for reducing substances of medium to extreme hardness and for brittle and tough materials. The ultimate fineness can be as little as 1 mm and, depending on the material being processed, may be even less. Maximum recommended grain size for feedstock product is 50 mm.
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 - 50 mm Adjusted gap width: < 1 mm Final grain size: < 5 mm Filling ratio of grinding chamber: approx.
Shipping and installation Target groups: Owner, freight forwarder, operators 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 period since, in case of a claim, returning in unsuitable packaging can jeopardize your guarantee entitlements.
Installation Set up the BB 100 only on a solid, level surface. The jaw crusher should be anchored to provide sufficient protection against tipping; use the holes in the feet of the BB 100 for this purpose; see Fig. 1. The vibrations transmitted to the environment by the free mass moments in the BB 100 will be only barely perceptible. Electrical connection Refer to the data plate for information on the voltage and frequency at which the BB 100 is to be operated.

The operating controls and their functions Summary table Element 2/7/2012 Description Function A ON/OFF switch and motor protection Starts and stops the jaw crusher drive; isolates the motor (overload) switch from the power supply in case of overload. B Fill hopper Allows for the feed of material; prevents unintentionally reaching into the crushing chamber; prevents ejection of the material being processed. C Receiver drawer V = 2000 ml Accepts the crushed sample material.
Starting the BB 100 The BB 100 may be started only when the crushing chamber and fill hopper are empty. Product which is present in the crushing chamber or fill hopper 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 BB 100. Fig. 2 Press button I. The motor starts and the movable arm is set in motion.
Adjust the gap width * * * * * Start the BB 10 (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 L 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 Fig. 4 * * * Start the BB 100 (idling, without product). Loosen the lock nut N (turn to the left).
Working instructions Target group: Laboratory technicians General The BB 100 is a rugged, floor-mounted unit which is used primarily for preliminary crushing in preparation for final size reduction. Its continuous operating concept also makes the BB 100 suitable for integration into fully automatic and semi-automatic processing lines. The performance data, throughput rates and ultimate fineness will depend on the fracture properties and hardness of the product and on the gap width which is selected.
General Cleaning An industrial vacuum cleaner and a stable, long-handled brush are best suited for cleaning the BB 100. The stationary breaker arm S can also be removed to allow for sufficient cleaning of the crushing chamber. See Fig. 7 Unscrew the machine screws E. Swing back the fill hopper B. Grasp the breaker arm S at the handle R and pull out the pin Q. Lift out the breaker arm S. The crushing chamber is now accessible. Assemble in reverse order. Fig.
Maintenance The BB 100 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. Quan. in kg Interval, hours of operation 1 0.005 50 2 0.003 50 Use the grease gun supplied with the BB 100 for lubrication purposes. Ordinary multi-purpose graese can be used as lubricant, e.g. EP 4685 by ESSO / SHELL or BP. CE Fig.
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 E. Swing back the fill hopper B. Grasp the breaker arm S at the handle R and pull out the pin Q. Lift out the breaker arm S. Unscrew the machine screws H. Remove the clamping shims G. Replace the breaker jaws J. Assemble in reverse order. Set the gap width as described in this instruction manual. Fig.
