Jaw Crusher
Model BB100 / BB200

The jaw crushers are suitable for the rough crushing and pre-crushing of medium-hard, hard, brittle and hard-ductile materials. With their level of performance and safety, they are ideal for preparing samples both in laboratories and industrial plants. A distinguishing feature of the jaw crushers is the capability to adjust the gap to any desired width from 0 to 20 or 30 mm.

This is your guarantee for output grain size matched exactly to the requirements at hand. In contrast to units where the width is adjusted in discrete steps, it is also possible to reset the zero point to compensate for wear, and that means output which is always exactly uniform. Robust design, simple operation and cleaning are further features. Both crushers can be used in intermittent mode for small sample quantities, and in continuous mode for larger quantities.

ADVANTAGES
  • Large throughput
  • High crushing performance
  • Infinite gap adjustment
  • Scale of gap width indication
  • Very economical
  • High final fineness
  • Hinged safety hopper with
  • Quick-release
  • Brake motor with safety switch
  • Easy cleaning of crushing chamber
  • 2-year guarantee, design to CE specifications
With a maximum feed size and a minimum gap width, the degree of crushing (feed size to end fineness) is up to 50:1. The throughput and end fineness depend on the model type, the gap width set and the crushing properties of the feed material. The feed funnel cannot be reached into and can be simply hinged open for a fast cleaning of the grinding chamber. A safety switch and brake motor ensure immediate shut-down if the unit is incorrectly opened or switched on. The fixed crushing arm can be removed easily for cleaning and jaw replacement. The crushed material is collected in a drawer with a capacity of 2 and 5 litres respectively. In the case of larger quantities and free discharge downwards, one can work without a drawer.
The jaw crushers crush medium-hard, hard, brittle and hard-ductile materials with degrees of hardness up to 10 according to Mohs. For example, bakelite, bauxite, concrete, chemical raw materials, ores, rocks, glass, ceramics, coal, coke, corundum, artificial resins, alloys, quartz, salts, chamotte, slags, cement clinker and many other substances can be crushed from coarse to fine quickly and gently. The crushers are specially designed for the preparation of laboratory samples, but they can also be used to make samples and product in small quantities in industrial plants.
With the type BB 100 the jaw opening width is 60 x 60 mm and the maximum feed size 50 mm. The type BB 200 has a jaw opening width of 100 x 100 mm and a maximum feed grain size of 90 mm. The gap width can, according to model, be infinitely adjusted from 0 to 20 and 0 to 30 mm respectively and read off.

SELECTION OF CRUSHERS AND CRUSHING JAWS

The crusher type is selected primarily according to the feed grain size and the feed quantity.
With grain sizes up to 90 mm, larger quantities and difficult-to-crush materials such as ferrochrome, the BB 200 can be recommended, and for grain sizes up to 50 mm and small quantities the BB 100.
Crushing jaws are available in 3 materials
  • Manganese steel
  • Stainless steel
  • Tungsten carbide
Features
  • Tungsten carbide is the most abrasion-resistant and purest material, but in many cases jaws of manganese steel are adequate.
  • Stainless steel can be recommended when the feed material to be expected is not too hard and could form rust.
  • The side wearing plates are of stainless steel as standard.

MATERIALS BASE COMPOSITION
Crushing jaws manganese steel 85% Fe, 13%Mn, 1.5%C, 0.5% Si
stainless steel 66.8% Fe, 19.5% Cr, 10% Ni, 2% Si, 1.5% Mn

tungsten carbide 90% WC, 10% Co

BB 100 & BB 200 TECHNOLOGY

The jaw crushers are forced-feed crushers. The feed material passes through the safety hopper into the grinding chamber. Crushing takes place in the wedge-shaped shaft between the fixed crushing arm and that moved by an eccentric shaft. With the elliptical motion, the feed material is crushed, conveyed downward and collected in the collecting drawer. The fixed, adjustable crushing arm can be moved towards the movable arm by means of a spindle. This infinite gap adjustment with scale ensures an optimum setting corresponding to the feed material and the desired end fineness.

A Belleville spring washer integrated in the spindle adjustment mechanism provides extra overload protection in addition to the motor protection switch. The drive mechanism works via V belts using a robust brake motor with 0.75 and 1.5 kW rated power respectively. The large belt pulley is at the same time a flywheel and ensures smooth and powerful running.
