Safety Target group: All persons concerned in any way with the machine. The SR 200 is a highly modern, efficient product from Retsch GmbH. It is state of the art. If the user handles the machine in a proper fashion and with knowledge of the technical documentation present here, it is completely safe operationally.
Warning signs We give warnings using the following symbols: ! Personal injury Material damage Repairs These operating instructions do not include any repair instructions. For your own safety, repairs may only be carried out by Retsch GmbH or an authorised agent (service technicians).
Technical Data Machine type designation: SR 200 Application in the case of proper use For uses where very frequently different materials have to be ground and it is necessary to open the door to clean the grinding chamber after every grinding operation. The SR 200 is not designed as a production machine, but as a laboratory unit, meant for 8-hour single-shift operation. The SR 200 crushes dry, soft to medium-hard materials with a hardness of up to about 4 according to Mohs.
Drive 1-phase AC motor with brake or Three-phase current motor with brake Speed 2850min-1 at 50Hz 3420min-1 at 60Hz Rated power 1100 Watt Feed grain size max. 15mm With single-piece feed also up to 20mm Volume of collecting pan 5,000 ml or 30,000ml Noise data Noise measurement according to DIN 45635-31-01-KL3 Noise data are dependent on the fracturing properties fo the product beeing ground.

Transport and setting up Target group: Operators, Forwarders, Users Packing The packing is adjusted to the transport route. It complies with the generally applicable packing regulations. Please keep the packing for the whole of the guarantee period. If, in the case of a complaint, the unit is returned in inadequate packing, your guarantee rights may be jeopardised. Transport To transport the SR 200 use the ring bolt H. Fig.1 Fig.
We recommend that the SR 200 be mounted on an underframe, which can be supplied as an accessory. Fig.2 Mounting: * 6 * * 3 4 * 5 1 9 2 7 8 Connect centre cross-piece 9 base side pieces 8 using the cylinder-head screws 1 Push covering caps 2 onto the projecting thread Place stand tube 3 in the sleeve 4 and fasten tight with the headless screws 5 If necessary, the underframe can be aligned using the cylinder-head screws 6 So as to be able to fasten the underframe with screws, maximum diam.
Setting up on the laboratory table You can also mount the SR 200 on your laboratory table. Fig.4 * Measure thickness of laboratory table. The thickness should not be less than 30mm to ensure that safe working with the SR 200 is not adversely affected. * Use screws with a max. diam.

Operating elements and their function Overview of operating elements Item Element Figure Function A Power switch with ON/OFF button A1 Power switch with knob B Door lock D Feed funnel at door E Filter hose Page 15 Prevents build-up of the air pressure generated by the rotating rotor and thus accelerates material throughput. F 5l collecting pan Page 15 Takes the crushed material.
Opening and closing of mill housing Only open when the SR 200 is switched off. * Press button 0 on power switch A or, with A1, turn to OFF position Fig.6 0 I * Press hand wheel B and turn in anticlockwise direction * Hand wheel locks into end position * the door can be opened * close in reverse order Fig.6 Only close the door when the contact surfaces are absolutely free of material to be crushed or other contaminants. Mechanical components and the seal may be damaged.
Insert grinding insert 180° with frame and sieve insert A selection of grinding inserts with frames and sieve inserts of stainless steel with Conidur or round perforations are available as accessories. Fig.8 Conidur 0.08/0.12/0.20/0.25/0.50/ 0.75/1.0/1.25/1.5/2.0mm Round hole 3.0/4.0/5.0/6.0/8.0/10.
Filter hose and collecting pan With the use of a cloth filter hose or a Conidur filter, available as an accessory, between the SR 200 and the collecting pan, the air stream caused by the rotating rotor is taken off and conveyed downward to the material discharge. Furthermore, it accelerates the material throughput and ensures a gentle crushing process. Fig.10 * Push filter hose E over the flange while holding the clamping clip at an angle.
Assembly of feed device When feeding larger quantities, it is advisable in general to feed the material to be crushed evenly using a feed device. This largely prevents any unnecessary load on the grinding tools and reduces possible friction heat. An appropriate means of ensuring even material feed is use of the feed device of the type DR 100/75, which is available as an accessory. Fig.15 Fig.12 Fig.13 Fig. 14 Prepare the DR 100/75 for feed operation in accordance with its operating instructions.
Working Instructions Target group: Laboratory personnel General The SR 200 is highly modern, high-performance product from Retsch GmbH. In view of the wide range of accessories available, the SR 200 rotor beater mill is a unit with many varied uses in the chemical and pharmaceutical sectors, mineralogy and biology etc. in industrial and research laboratories.
General Cleaning SR 200 The SR 200 can be cleaned with brushes, paintbrushes and possibly an industrial vacuum cleaner, as well as compressed air. To clean the grinding chamber on the SR 200 the motor brake can be released at the lever G ( Fig.16 ). the rotor is now easy to turn and this facilitates cleaning. The SR 200's type of protection is IP54. Fig.16 ! Do not clean the SR 200 under running water.
