BSM

Established in 2000 Bulkmatic Solids Machinery has introduced a revised and re-designed product range of equipment for the handling and processing of dry bulk materials. Although technology is advancing at an alarming rate there is no substitute for experience. We combine both these elements to offer outstanding product quality and economy. Bulkmatic was founded by a team of dedicated entrepreneurs with a combined total of over 100 years of experience in the materials handling field. The multidisciplinary design team ensures that the equipment is designed with the following in mind: functionality based on over 27 years of practical experience in the industry, innovative and modern manufacturing methods and a constant awareness of the costs involved in manufacturing. With a fresh approach, old problems in industry are being examined in detail and new solutions found.

Bulk Solid Handling Equipment

Bulkmatic manufactures a comprehensive range of quality equipment for the processing and conveying of bulk powders and granules. Use of the latest technology available such as 3-D CAD, laser profiling, water jetting, CNC bending and machining ensures repeatable accuracy and fully interchangeable spare parts.

We design and manufacture equipment that includes amongs others: rotary vane feeders, flap valves, knife gates, screw conveyors, diverter valves, vibrating bin dischargers, telescopic loaders and ribbon blenders specifically for the handling of powdered and granular solids. All of the products are designed and manufactured in-house.

Blenders & Mixers:
Bulkmatic Ribbon Blenders are manufactured using the “contra-flow” ribbon to ensure gentle and even mixing of product. Ribbon Blenders are primarily used in the food industry but have applications in a diverse spectrum of industry such as blending of cement, fertiliser, grease constituents and plastic masterbatch.

Laser profiling of supports and mounting brackets ensures consistent part size and ensures that drive shaft and ribbon shaft are correctly aligned during assembly. The robust trough is designed for structural rigidity allowing the ribbon blenders to be started in the filled condition without distorting the trough.

For special applications contact Bulkmatic to arrange for blending tests on specific materials. Maintenance is simple as the ribbon shaft can be removed from the trough without opening the bearings, stuffing boxes or removing the drive shaft. Stuffing boxes are fitted with four gland packing layers and can be supplied with air purging on request.

Optional extras include steam jacketing, stainless steel 304 or 316 construction, support stand, loading platform with stair access and pneumatic knifegate for the outlet

Bucket Elevators:

Bulkmatic Bucket Elevators are available in standard casing sizes to tie in with flange arrangements of associated equipment such as screw conveyors, rotary feeders and diverter chutes. This allows seamless integration of feeding equipment in terms of the complete materials handling system that the bucket elevator is to be fitted into.

Bulkmatic supplies belt or chain bucket elevators. Drive arrangements are either belt driven via a shaft mounted gearbox with backstop bearing or direct drive with a flexible coupling and backstop.

The material of construction is matched to the application and the units are available in mild steel or stainless steel. Depending on the size of the buckets these can be supplied in HDPE, mild steel or stainless steel.

Optional extras include access platforms support brackets, hoist frames on access platforms, catladders, rotation sensors and belt drift sensors.

Bulk tanker loaders:

Bulkmatic Bulk Tanker Loaders are designed to assist in unloading bulk bags into standard height bulk tankers. Very often imported chemicals, flocculants and other granular and powdered materials are imported in bulk bags. These are then transported from the harbours in bulk bags to minimize transport costs to the point of distribution.

Here the products often need to be loaded into bulk tankers for final delivery to the customer. The bulk tanker loader takes care of this reloading operation. Two bulk bag hatches allow the operator to increase the loading speed by unloading two bulk bags at the same time. An incline screw then elevates the product to the inlet hatch of a bulk tanker.

The unit is also mobile and can be moved to a desired position as required. While standing on all four wheels the unit has a total height of 4240mm. The complete unit is then tilted upward which fixes its standing position and elevates the screw outlet to clear a standard bulk tanker at 4250mm with a total unit height of 5840mm.

The operator accesses the bulk spout opening hatches by standing on a platform that is reached via a stairway attached to the bulk tanker loader. Bag opening is safely accessible below the bulk bag resting tray.

As an option an integrated reverse jet pulse filter can be fitted but requires separate access to compressed air. Units can be manufactured in mild steel or stainless steel depending on the product to be conveyed.

Knife Gates - Square: Hand or Chain Wheel operated

Bulkmatic Knife Gates are manufactured in two basic forms - “Hand operated” or “Chain Wheel operated”. Laser profiling results in a light but robust knife gate. The inlet ports are generously sized with a protective cover shroud insert. This shroud ensures that contact of material with the sealing strips above the gate blade is minimised reducing wear and maintenance. The outlet port opening is larger than the inlet ensuring minimal chances of material hangup.

The design of the stuffing box is such that the packing can be changed with the knife gate blade in position and only the cover plate removed for access. The Hand Wheel operated valve uses a conventional hand wheel while the Chain Wheel operated version is ideal for hand operation where the gate is at an elevated position. Limit or proximity switches can be fitted as optional extras.

Knife Gates can also be supplied in stainless steel.

Rotary Vane Feeders:

Bulkmatic Rotary Vane Feeder Model Square D Type is a low cost direct driven feeder for dust feeding applications. It is specifically designed to feed material from dust collection hoppers and other low pressure applications.

The design includes an impeller which is mounted directly onto the gearbox shaft and an end plate mounted bearing with lip seals on the non-driven side. The inlet ports have “V’s” cast into the side wall to create a scissor cutting action between impeller blade and casing.

This ensures smooth rotation without the “chopping effect” experienced with other valves. The result is increased bearing and impeller tip life. The D type valve has a closed end impeller and has adjustable tips fitted as standard. This valve is suitable for applications where the pressure differential is below 30 kPa and the material is non abrasive and free flowing.

Various options are available including different materials of construction such as stainless steel, soft flexible or hard wearing impeller tips, body venting, inlet scrapers and hard chromed casings.

Sampling screws - motorised / hand

Bulkmatic Sampling Screws are designed to extract material sample from a stream of material flowing down a chute. The screw is designed to pick up material through a slot at the top of the screw and draw the material to a flanged outlet on the side. Provision has been made to purge the screw through an off-centre slot at the bottom of the screw when the motor is run in the opposite direction.

Precision laser cut flanges, side walls and screw conveyor tube slots ensure a quality finish with consistent hole spacing on the flanges.

The standard unit is compatible with other Bulkmatic equipment such as rotary feeders, flap valves and knife gates.

Standard outlet flange is a NB50 SABS 1123/1000 flange. Other flanges can be supplied on request.

Standard material of manufacture is mild steel. Stainless steel 304 or 316 units with a quick release mechanism can be supplied for food grade applications. Round units are also available to suit customer specific flanging and chutes.

Silo Safety Valves (SSV) - Gravity Operated

Bulkmatic Silo Safety Valves are used to protect bins and silos from overpressure and underpressure damage. Underpressure collapse of a silo may occur if a column of material that has hung up in the silo suddenly dislodges and slides down creating a vacuum above the material. For the prevention of overpressure damage the valve would typically be fitted to bins and silos that are fed by a pneumatic conveying line or fed from a bulk tanker. Optional weather cowls are supplied for outdoor applications. A rubber seal on both flaps ensures an air tight seal.

The overpressure valve pressure and vacuum settings can be adjusted by changing the weights fitted to the sealing flaps. Standard settings are at +1.5 kPa and –1.5 kPa. The unit may not be used as a substitute for an explosion panel for potentially explosive products in the bin or silo. Typical material of construction is mild steel. Stainless steel units are also available. The silo safety valve can be ordered as an overpressure valve, vacuum breaker valve or as a combination of the two.
