GÜRSAN has been working on mineral processing technology
IMPACT PRIMARY UNITS
3 dimensional CAD design program has been used during design of Units; a software program where stresses to exert effect on critical parts so designed were analyzed within a computer environment has been used.
Taking into consideration the requirements of end user the following targets have been selected on design of products:
• Higher productivity,
• Easy and simple operation,
• Easy transportation,
• Easy and rapid installation.
Gür-san Primary units have been built around Gürsan Jaw and Impact Crushers which proved themselves on all kinds of materials for many years.
Jaw Crushers which are placed at the heart of our Jaw Primary units have been designed and manufactured for the purpose of using them in the first stage crushing of all types of materials ranging from soft limestone rock to the hardest basalt. These crushers have been providing unique and exclusive operational advantages to their users with their high flywheel speeds, jaw grabbing angles, safety plates of their pitmans and their rear blocks as well as their superior performances based on their geometry, reliabilities, durability and their user friendly adjustment mechanisms.
If the material to be crushed is soft or semi-hard, lower abrasive, then capacity and crushing rate will be much more higher, cubical values will be perfect; therefore our primer unit with impact crusher has been recommended as alternative.
In the course of numerous applications finish product can be produced without need for secondary crusher, eventually investment costs could be reduced. Several of numerous superior features of our user friendly impact crushers are: Hammers which can be easily replaced and presented also as chromium alloy, used reverse and plain, heavy-duty rotor, completely cable-controlled and hydraulic controlled adjustment system, primary apron preventing clogging, hydraulically opened upper body.
Another significant feature in our Impact Crushers is that they are equipped with a protection system against pieces of metal which might be present within the material fed to the Crusher. This protection system ensures that in case of entering of any material which is impossible to be crushed into crusher such material may pass through the machine without causing damage by removal of aprons automatically from rotor, and that the crushed should continue its trouble free operation by returning aprons to their adjusted original position after such unbreakable material left the machine.
Our Mobil Primary facilities have been provided with hydraulic legs in order to be able to carry out installation easily and quickly at the Work Site. This System makes it possible as soon as possible that the unit be lifted to studs at the Work Site. Hydraulic power unit which supply power to this system controls the system which adjusts the discharge setting, if the crusher on the facility has jaw. Adjustment of the crusher can be made easily by moving adjustment block to and front by means of pistons available at the rear of the crusher and by inserting or removing shim plates. If the crusher is of impact type this system provides assistance in making adjustment the clearance between the aprons and rotor and crusher plates and easy and rapid maintenance for armour, inings, rotor and hammers by opening upper body of the crusher.
Our Mobile primary units have been designed and manufactured as heavy duty type in so much as stationary units; both their hopper capacities and feeder structures are of capacity and structure which could be fed by heavy rock trucks. These feeding systems, depending on the request, are capable of feeding the material automatically without need for operator to the crusher as much as it needed, ensuring that the facility is to be fed in optimum capacity according to hardness of the material, adjustment position of the crusher.
Another a unique feature involved in our facilities however is the pre-screening system which has been solved at our feeders as compact. Thanks to this system fine material which is unnecessary to be fed to the crusher can be by-passed directly to the crusher’s conveyor belt; and in the mean time however the unwanted soil in the fine material is separated and conveyed to the soil conveyor belt. This unique system, whose duty has been performed by most companies by employing an extra screen, increases both capacity and production quality of your plant.
Our Primary Plants, in addition to standard features mentioned above, include according to demands of end users optional attachments such as hydraulic rock crushers, operator cabins, drive systems with diesel engine and generator, dust dumping system, finger grid by- pass sieve, magnetic separators on outlet conveyor belt and hoppers with larger volume capacity, etc.
In addition to all of foregoing features and specifications our primary units have been also manufactured EC Directives on Machine accepted by the European Community (CE Sign) like all other products of Gür-San.
